Struct gdnative_bindings::MultiMesh

impl MultiMesh

Constants

pub fn new() -> Ref<Self, Unique>

Creates a new instance of this object.

This is a reference-counted type. The returned object is automatically managed by Ref.

pub fn get_aabb(&self) -> Aabb

Returns the visibility axis-aligned bounding box in local space. See also VisualInstance.get_transformed_aabb.

pub fn color_format(&self) -> ColorFormat

Format of colors in color array that gets passed to shader.

pub fn custom_data_format(&self) -> CustomDataFormat

Format of custom data in custom data array that gets passed to shader.

pub fn get_instance_color(&self, instance: i64) -> Color

Gets a specific instance’s color.

pub fn instance_count(&self) -> i64

Number of instances that will get drawn. This clears and (re)sizes the buffers. By default, all instances are drawn but you can limit this with visible_instance_count.

pub fn get_instance_custom_data(&self, instance: i64) -> Color

Returns the custom data that has been set for a specific instance.

pub fn get_instance_transform(&self, instance: i64) -> Transform

Returns the Transform of a specific instance.

pub fn get_instance_transform_2d(&self, instance: i64) -> Transform2D

Returns the Transform2D of a specific instance.

pub fn mesh(&self) -> Option<Ref<Mesh, Shared>>

Mesh to be drawn.

pub fn physics_interpolation_quality(&self) -> PhysicsInterpolationQuality

Choose whether to use an interpolation method that favors speed or quality. When using low physics tick rates (typically below 20) or high rates of object rotation, you may get better results from the high quality setting. Note: Fast quality does not equate to low quality. Except in the special cases mentioned above, the quality should be comparable to high quality.

pub fn transform_format(&self) -> TransformFormat

Format of transform used to transform mesh, either 2D or 3D.

pub fn visible_instance_count(&self) -> i64

Limits the number of instances drawn, -1 draws all instances. Changing this does not change the sizes of the buffers.

pub fn reset_instance_physics_interpolation(&self, instance: i64)

When using physics interpolation, this function allows you to prevent interpolation on an instance in the current physics tick. This allows you to move instances instantaneously, and should usually be used when initially placing an instance such as a bullet to prevent graphical glitches.

pub fn set_as_bulk_array(&self, array: PoolArray<f32>)

Sets all data related to the instances in one go. This is especially useful when loading the data from disk or preparing the data from GDNative. All data is packed in one large float array. An array may look like this: Transform for instance 1, color data for instance 1, custom data for instance 1, transform for instance 2, color data for instance 2, etc… Transform is stored as 12 floats, Transform2D is stored as 8 floats, COLOR_8BIT / CUSTOM_DATA_8BIT is stored as 1 float (4 bytes as is) and COLOR_FLOAT / CUSTOM_DATA_FLOAT is stored as 4 floats.

pub fn set_as_bulk_array_interpolated(
 &self,
 array_current: PoolArray<f32>,
 array_previous: PoolArray<f32>
)

An alternative version of MultiMesh.set_as_bulk_array which can be used with physics interpolation. This method takes two arrays, and can set the data for the current and previous tick in one go. The renderer will automatically interpolate the data at each frame. This is useful for situations where the order of instances may change from physics tick to tick, such as particle systems. When the order of instances is coherent, the simpler MultiMesh.set_as_bulk_array can still be used with interpolation.

pub fn set_color_format(&self, format: i64)

Format of colors in color array that gets passed to shader.

pub fn set_custom_data_format(&self, format: i64)

Format of custom data in custom data array that gets passed to shader.

pub fn set_instance_color(&self, instance: i64, color: Color)

Sets the color of a specific instance by multiplying the mesh’s existing vertex colors. For the color to take effect, ensure that color_format is non-null on the MultiMesh and SpatialMaterial.vertex_color_use_as_albedo is true on the material. If the color doesn’t look as expected, make sure the material’s albedo color is set to pure white (Color(1, 1, 1)).

pub fn set_instance_count(&self, count: i64)

Number of instances that will get drawn. This clears and (re)sizes the buffers. By default, all instances are drawn but you can limit this with visible_instance_count.

pub fn set_instance_custom_data(&self, instance: i64, custom_data: Color)

Sets custom data for a specific instance. Although Color is used, it is just a container for 4 floating point numbers. The format of the number can change depending on the CustomDataFormat used.

pub fn set_instance_transform(&self, instance: i64, transform: Transform)

Sets the Transform for a specific instance.

pub fn set_instance_transform_2d(&self, instance: i64, transform: Transform2D)

Sets the Transform2D for a specific instance.

pub fn set_mesh(&self, mesh: impl AsArg<Mesh>)

Mesh to be drawn.

pub fn set_physics_interpolation_quality(&self, quality: i64)

Choose whether to use an interpolation method that favors speed or quality. When using low physics tick rates (typically below 20) or high rates of object rotation, you may get better results from the high quality setting. Note: Fast quality does not equate to low quality. Except in the special cases mentioned above, the quality should be comparable to high quality.

pub fn set_transform_format(&self, format: i64)

Format of transform used to transform mesh, either 2D or 3D.

pub fn set_visible_instance_count(&self, count: i64)

Limits the number of instances drawn, -1 draws all instances. Changing this does not change the sizes of the buffers.

Methods from Deref<Target = Resource>§

pub fn duplicate(&self, subresources: bool) -> Option<Ref<Resource, Shared>>

Duplicates the resource, returning a new resource with the exported members copied. Note: To duplicate the resource the constructor is called without arguments. This method will error when the constructor doesn’t have default values. By default, sub-resources are shared between resource copies for efficiency. This can be changed by passing true to the subresources argument which will copy the subresources. Note: If subresources is true, this method will only perform a shallow copy. Nested resources within subresources will not be duplicated and will still be shared. Note: When duplicating a resource, only exported properties are copied. Other properties will be set to their default value in the new resource.

Default Arguments

subresources - false

pub fn emit_changed(&self)

Sample code is GDScript unless otherwise noted.

Emits the changed signal. If external objects which depend on this resource should be updated, this method must be called manually whenever the state of this resource has changed (such as modification of properties). The method is equivalent to:

emit_signal("changed")

Note: This method is called automatically for built-in resources.

pub fn get_local_scene(&self) -> Option<Ref<Node, Shared>>

If [resource_local_to_scene][Self::resource_local_to_scene] is enabled and the resource was loaded from a PackedScene instantiation, returns the local scene where this resource’s unique copy is in use. Otherwise, returns null.

pub fn name(&self) -> GodotString

The name of the resource. This is an optional identifier. If [resource_name][Self::resource_name] is not empty, its value will be displayed to represent the current resource in the editor inspector. For built-in scripts, the [resource_name][Self::resource_name] will be displayed as the tab name in the script editor.

pub fn path(&self) -> GodotString

The path to the resource. In case it has its own file, it will return its filepath. If it’s tied to the scene, it will return the scene’s path, followed by the resource’s index.

pub fn get_rid(&self) -> Rid

Returns the RID of the resource (or an empty RID). Many resources (such as Texture, Mesh, etc) are high-level abstractions of resources stored in a server, so this function will return the original RID.

pub fn is_local_to_scene(&self) -> bool

If true, the resource will be made unique in each instance of its local scene. It can thus be modified in a scene instance without impacting other instances of that same scene.

pub fn set_local_to_scene(&self, enable: bool)

If true, the resource will be made unique in each instance of its local scene. It can thus be modified in a scene instance without impacting other instances of that same scene.

pub fn set_name(&self, name: impl Into<GodotString>)

The name of the resource. This is an optional identifier. If [resource_name][Self::resource_name] is not empty, its value will be displayed to represent the current resource in the editor inspector. For built-in scripts, the [resource_name][Self::resource_name] will be displayed as the tab name in the script editor.

pub fn set_path(&self, path: impl Into<GodotString>)

The path to the resource. In case it has its own file, it will return its filepath. If it’s tied to the scene, it will return the scene’s path, followed by the resource’s index.

pub fn setup_local_to_scene(&self)

This method is called when a resource with [resource_local_to_scene][Self::resource_local_to_scene] enabled is loaded from a PackedScene instantiation. Its behavior can be customized by overriding [_setup_local_to_scene][Self::_setup_local_to_scene] from script. For most resources, this method performs no base logic. ViewportTexture performs custom logic to properly set the proxy texture and flags in the local viewport.

pub fn take_over_path(&self, path: impl Into<GodotString>)

Sets the path of the resource, potentially overriding an existing cache entry for this path. This differs from setting [resource_path][Self::resource_path], as the latter would error out if another resource was already cached for the given path.

Methods from Deref<Target = Object>§

pub const NOTIFICATION_POSTINITIALIZE: i64 = 0i64

pub const CONNECT_DEFERRED: i64 = 1i64

pub const NOTIFICATION_PREDELETE: i64 = 1i64

pub const CONNECT_PERSIST: i64 = 2i64

pub const CONNECT_ONESHOT: i64 = 4i64

pub const CONNECT_REFERENCE_COUNTED: i64 = 8i64

pub fn add_user_signal(
 &self,
 signal: impl Into<GodotString>,
 arguments: VariantArray
)

Adds a user-defined signal. Arguments are optional, but can be added as an Array of dictionaries, each containing name: String and type: int (see [enum Variant.Type]) entries.

Default Arguments

arguments - [ ]

pub unsafe fn call(
 &self,
 method: impl Into<GodotString>,
 varargs: &[Variant]
) -> Variant

Sample code is GDScript unless otherwise noted.

Calls the method on the object and returns the result. This method supports a variable number of arguments, so parameters are passed as a comma separated list. Example:

call("set", "position", Vector2(42.0, 0.0))

Note: In C#, the method name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined methods where you should use the same convention as in the C# source (typically PascalCase).

Safety

This function bypasses Rust’s static type checks (aliasing, thread boundaries, calls to free(), …).

pub unsafe fn call_deferred(
 &self,
 method: impl Into<GodotString>,
 varargs: &[Variant]
) -> Variant

Sample code is GDScript unless otherwise noted.

Calls the method on the object during idle time. This method supports a variable number of arguments, so parameters are passed as a comma separated list. Example:

call_deferred("set", "position", Vector2(42.0, 0.0))

Note: In C#, the method name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined methods where you should use the same convention as in the C# source (typically PascalCase).

Safety

This function bypasses Rust’s static type checks (aliasing, thread boundaries, calls to free(), …).

pub unsafe fn callv(
 &self,
 method: impl Into<GodotString>,
 arg_array: VariantArray
) -> Variant

Sample code is GDScript unless otherwise noted.

Calls the method on the object and returns the result. Contrarily to call, this method does not support a variable number of arguments but expects all parameters to be via a single Array.

callv("set", [ "position", Vector2(42.0, 0.0) ])

Safety

This function bypasses Rust’s static type checks (aliasing, thread boundaries, calls to free(), …).

pub fn can_translate_messages(&self) -> bool

Returns true if the object can translate strings. See set_message_translation and tr.

pub fn connect(
 &self,
 signal: impl Into<GodotString>,
 target: impl AsArg<Object>,
 method: impl Into<GodotString>,
 binds: VariantArray,
 flags: i64
) -> GodotResult

Sample code is GDScript unless otherwise noted.

Connects a signal to a method on a target object. Pass optional binds to the call as an Array of parameters. These parameters will be passed to the method after any parameter used in the call to emit_signal. Use flags to set deferred or one-shot connections. See ConnectFlags constants. A signal can only be connected once to a method. It will print an error if already connected, unless the signal was connected with CONNECT_REFERENCE_COUNTED. To avoid this, first, use is_connected to check for existing connections. If the target is destroyed in the game’s lifecycle, the connection will be lost. Examples:

connect("pressed", self, "_on_Button_pressed") # BaseButton signal
connect("text_entered", self, "_on_LineEdit_text_entered") # LineEdit signal
connect("hit", self, "_on_Player_hit", [ weapon_type, damage ]) # User-defined signal

An example of the relationship between binds passed to connect and parameters used when calling emit_signal:

connect("hit", self, "_on_Player_hit", [ weapon_type, damage ]) # weapon_type and damage are passed last
emit_signal("hit", "Dark lord", 5) # "Dark lord" and 5 are passed first
func _on_Player_hit(hit_by, level, weapon_type, damage):
    print("Hit by %s (lvl %d) with weapon %s for %d damage" % [hit_by, level, weapon_type, damage])

Default Arguments

binds - [ ]
flags - 0

pub fn disconnect(
 &self,
 signal: impl Into<GodotString>,
 target: impl AsArg<Object>,
 method: impl Into<GodotString>
)

Disconnects a signal from a method on the given target. If you try to disconnect a connection that does not exist, the method will print an error. Use is_connected to ensure that the connection exists.

pub fn emit_signal(
 &self,
 signal: impl Into<GodotString>,
 varargs: &[Variant]
) -> Variant

Sample code is GDScript unless otherwise noted.

Emits the given signal. The signal must exist, so it should be a built-in signal of this class or one of its parent classes, or a user-defined signal. This method supports a variable number of arguments, so parameters are passed as a comma separated list. Example:

emit_signal("hit", weapon_type, damage)
emit_signal("game_over")

pub fn get(&self, property: impl Into<GodotString>) -> Variant

Returns the Variant value of the given property. If the property doesn’t exist, this will return null. Note: In C#, the property name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined properties where you should use the same convention as in the C# source (typically PascalCase).

pub fn get_class(&self) -> GodotString

Returns the object’s class as a String. See also is_class. Note: get_class does not take class_name declarations into account. If the object has a class_name defined, the base class name will be returned instead.

pub fn get_incoming_connections(&self) -> VariantArray

Returns an Array of dictionaries with information about signals that are connected to the object. Each Dictionary contains three String entries:

source is a reference to the signal emitter.
signal_name is the name of the connected signal.
method_name is the name of the method to which the signal is connected.

pub fn get_indexed(&self, property: impl Into<NodePath>) -> Variant

Gets the object’s property indexed by the given NodePath. The node path should be relative to the current object and can use the colon character (:) to access nested properties. Examples: "position:x" or "material:next_pass:blend_mode". Note: Even though the method takes NodePath argument, it doesn’t support actual paths to Nodes in the scene tree, only colon-separated sub-property paths. For the purpose of nodes, use Node.get_node_and_resource instead.

pub fn get_instance_id(&self) -> i64

Returns the object’s unique instance ID. This ID can be saved in EncodedObjectAsID, and can be used to retrieve the object instance with [method @GDScript.instance_from_id].

pub fn get_meta(
 &self,
 name: impl Into<GodotString>,
 default: impl OwnedToVariant
) -> Variant

Returns the object’s metadata entry for the given name. Throws error if the entry does not exist, unless default is not null (in which case the default value will be returned).

Default Arguments

default - null

pub fn get_meta_list(&self) -> PoolArray<GodotString>

Returns the object’s metadata as a PoolStringArray.

pub fn get_method_list(&self) -> VariantArray

Returns the object’s methods and their signatures as an Array.

pub fn get_property_list(&self) -> VariantArray

Returns the object’s property list as an Array of dictionaries. Each property’s Dictionary contain at least name: String and type: int (see [enum Variant.Type]) entries. Optionally, it can also include hint: int (see [PropertyHint][PropertyHint]), hint_string: String, and usage: int (see [PropertyUsageFlags][PropertyUsageFlags]).

pub fn get_script(&self) -> Option<Ref<Reference, Shared>>

Returns the object’s Script instance, or null if none is assigned.

pub fn get_signal_connection_list(
&self,
signal: impl Into<GodotString>
) -> VariantArray

Returns an Array of connections for the given signal.

pub fn get_signal_list(&self) -> VariantArray

Returns the list of signals as an Array of dictionaries.

pub fn has_meta(&self, name: impl Into<GodotString>) -> bool

Returns true if a metadata entry is found with the given name.

pub fn has_method(&self, method: impl Into<GodotString>) -> bool

Returns true if the object contains the given method.

pub fn has_signal(&self, signal: impl Into<GodotString>) -> bool

Returns true if the given signal exists.

pub fn has_user_signal(&self, signal: impl Into<GodotString>) -> bool

Returns true if the given user-defined signal exists. Only signals added using add_user_signal are taken into account.

pub fn is_blocking_signals(&self) -> bool

Returns true if signal emission blocking is enabled.

pub fn is_class(&self, class: impl Into<GodotString>) -> bool

Returns true if the object inherits from the given class. See also get_class. Note: is_class does not take class_name declarations into account. If the object has a class_name defined, is_class will return false for that name.

pub fn is_connected(
 &self,
 signal: impl Into<GodotString>,
 target: impl AsArg<Object>,
 method: impl Into<GodotString>
) -> bool

Returns true if a connection exists for a given signal, target, and method.

pub fn is_queued_for_deletion(&self) -> bool

Returns true if the Node.queue_free method was called for the object.

pub fn notification(&self, what: i64, reversed: bool)

Send a given notification to the object, which will also trigger a call to the [_notification][Self::_notification] method of all classes that the object inherits from. If reversed is true, [_notification][Self::_notification] is called first on the object’s own class, and then up to its successive parent classes. If reversed is false, [_notification][Self::_notification] is called first on the highest ancestor (Object itself), and then down to its successive inheriting classes.

Default Arguments

reversed - false

pub fn property_list_changed_notify(&self)

Notify the editor that the property list has changed, so that editor plugins can take the new values into account. Does nothing on export builds.

pub fn remove_meta(&self, name: impl Into<GodotString>)

Removes a given entry from the object’s metadata. See also set_meta.

pub fn set(&self, property: impl Into<GodotString>, value: impl OwnedToVariant)

Assigns a new value to the given property. If the property does not exist or the given value’s type doesn’t match, nothing will happen. Note: In C#, the property name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined properties where you should use the same convention as in the C# source (typically PascalCase).

pub fn set_block_signals(&self, enable: bool)

If set to true, signal emission is blocked.

pub fn set_deferred(
 &self,
 property: impl Into<GodotString>,
 value: impl OwnedToVariant
)

Assigns a new value to the given property, after the current frame’s physics step. This is equivalent to calling set via call_deferred, i.e. call_deferred("set", property, value). Note: In C#, the property name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined properties where you should use the same convention as in the C# source (typically PascalCase).

pub fn set_indexed(
 &self,
 property: impl Into<NodePath>,
 value: impl OwnedToVariant
)

Sample code is GDScript unless otherwise noted.

Assigns a new value to the property identified by the NodePath. The node path should be relative to the current object and can use the colon character (:) to access nested properties. Example:

set_indexed("position", Vector2(42, 0))
set_indexed("position:y", -10)
print(position) # (42, -10)

pub fn set_message_translation(&self, enable: bool)

Defines whether the object can translate strings (with calls to tr). Enabled by default.

pub fn set_meta(&self, name: impl Into<GodotString>, value: impl OwnedToVariant)

Adds, changes or removes a given entry in the object’s metadata. Metadata are serialized and can take any Variant value. To remove a given entry from the object’s metadata, use remove_meta. Metadata is also removed if its value is set to null. This means you can also use set_meta("name", null) to remove metadata for "name".

pub fn set_script(&self, script: impl AsArg<Reference>)

Assigns a script to the object. Each object can have a single script assigned to it, which are used to extend its functionality. If the object already had a script, the previous script instance will be freed and its variables and state will be lost. The new script’s [_init][Self::_init] method will be called.

pub fn to_string(&self) -> GodotString

Returns a String representing the object. If not overridden, defaults to "[ClassName:RID]". Override the method [_to_string][Self::_to_string] to customize the String representation.

pub fn tr(&self, message: impl Into<GodotString>) -> GodotString

Translates a message using translation catalogs configured in the Project Settings. Only works if message translation is enabled (which it is by default), otherwise it returns the message unchanged. See set_message_translation.
