Struct fyrox::scene::terrain::Terrain

pub struct Terrain { /* private fields */ }

Terrain is a height field where each point has fixed coordinates in XZ plane, but variable Y coordinate. It can be used to create landscapes. It supports multiple layers, where each layer has its own material and mask.

Chunking

Terrain itself does not define any geometry or rendering data, instead it uses one or more chunks for that purpose. Each chunk could be considered as a “sub-terrain”. You can “stack” any amount of chunks from any side of the terrain. To do that, you define a range of chunks along each axes. This is very useful if you need to extend your terrain in a particular direction. Imagine that you’ve created a terrain with just one chunk (0..1 range on both axes), but suddenly you found that you need to extend the terrain to add some new game locations. In this case you can change the range of chunks at the desired axis. For instance, if you want to add a new location to the right from your single chunk, then you should change width_chunks range to 0..2 and leave length_chunks as is (0..1). This way terrain will be extended and you can start shaping the new location.

Layers

Layer is a material with a blending mask. Layers helps you to build a terrain with wide variety of details. For example, you can have a terrain with 3 layers: grass, rock, snow. This combination can be used to create a terrain with grassy plateaus, rocky mountains with snowy tops. Each chunk (see above) can have its own set of materials for each layer, however the overall layer count is defined by the terrain itself. An ability to have different set of materials for different chunks is very useful to support various biomes.

Level of detail (LOD)

Terrain has automatic LOD system, which means that the closest portions of it will be rendered with highest possible quality (defined by the resolution of height map and masks), while the furthest portions will be rendered with lowest quality. This effectively balances GPU load and allows you to render huge terrains with low overhead.

The main parameter that affects LOD system is block_size (Terrain::set_block_size), which defines size of the patch that will be used for rendering. It is used to divide the size of the height map into a fixed set of blocks using quad-tree algorithm.

Current implementation uses modified version of CDLOD algorithm without patch morphing. Apparently it is not needed, since bilinear filtration in vertex shader prevents seams to occur.

Painting

Terrain has a single method for “painting” - Terrain::draw, it accepts a brush with specific parameters, which can either alternate height map or a layer mask. See method’s documentation for more info.

Ray casting

You have two options to perform a ray casting:

1. By using ray casting feature of the physics engine. In this case you need to create a Heighfield collider and use standard crate::scene::graph::physics::PhysicsWorld::cast_ray method.
2. By using Terrain::raycast - this method could provide you more information about intersection point, than physics-based.

Physics

As usual, to have collisions working you need to create a rigid body and add an appropriate collider to it. In case of terrains you need to create a collider with Heightfield shape and specify your terrain as a geometry source.

pub fn chunks_mut(&mut self) -> &mut [Chunk]

Returns a mutable reference to chunks of the terrain.

Sets a new set of properties of the node.

pub fn set_lifetime(&mut self, time_seconds: Option<f32>) -> &mut Base

Sets lifetime of node in seconds, lifetime is useful for temporary objects. Example - you firing a gun, it produces two particle systems for each shot: one for gunpowder fumes and one when bullet hits some surface. These particle systems won’t last very long - usually they will disappear in 1-2 seconds but nodes will still be in scene consuming precious CPU clocks. This is where lifetimes become handy - you just set appropriate lifetime for a particle system node and it will be removed from scene when time will end. This is efficient algorithm because scene holds every object in pool and allocation or deallocation of node takes very little amount of time.

pub fn lifetime(&self) -> Option<f32>

Returns current lifetime of a node. Will be None if node has undefined lifetime. For more info about lifetimes see set_lifetime.

pub fn parent(&self) -> Handle<Node>

Returns handle of parent node.

Set new mobility for the node. See Mobility docs for more info.

pub fn mobility(&self) -> Mobility

Return current mobility of the node.

pub fn global_visibility(&self) -> bool

Returns combined visibility of an node. This is the final visibility of a node. Global visibility calculated using visibility of all parent nodes until root one, so if some parent node upper on tree is invisible then all its children will be invisible. It defines if object will be rendered. It is not the same as real visibility from point of view of a camera. Use frustum-box intersection test instead.

pub fn original_handle_in_resource(&self) -> Handle<Node>

Handle to node in scene of model resource from which this node was instantiated from.

Notes

pub fn remove_all_scripts(&mut self)

Removes all assigned scripts from the scene node. The scripts will be removed from first-to-last order an their actual destruction will happen either on the current update tick of the parent graph (if it was removed from some other script) or in the next update tick.

pub fn replace_script(&mut self, index: usize, script: Option<Script>)

pub fn try_get_script_component<C>(&self) -> Option<&C>

where C: Any,

Tries find a component of the given type C across all available scripts of the node. If you want to search a component C in a particular script, then use Self::try_get_script and then search for component in it.

pub fn try_get_script_component_mut<C>(&mut self) -> Option<&mut C>

where C: Any,

pub fn script_count(&self) -> usize

Returns total count of scripts assigned to the node.

pub fn script(&self, index: usize) -> Option<&Script>

Returns a shared reference to a script instance with the given index. This method will return None if the index is out of bounds or the script is temporarily not available. This could happen if this method was called from some method of a ScriptTrait. It happens because of borrowing rules - you cannot take another reference to a script that is already mutably borrowed.

pub fn scripts(&self) -> impl Iterator<Item = &Script>

Returns an iterator that yields all assigned scripts.

pub fn script_mut(&mut self, index: usize) -> Option<&mut Script>

Returns a mutable reference to a script instance with the given index. This method will return None if the index is out of bounds or the script is temporarily not available. This could happen if this method was called from some method of a ScriptTrait. It happens because of borrowing rules - you cannot take another reference to a script that is already mutably borrowed.

Important notes

Do not replace script instance using mutable reference given to you by this method. This will prevent correct script de-initialization! Use Self::replace_script if you need to replace the script.

pub fn scripts_mut(&mut self) -> impl Iterator<Item = &mut Script>

Returns an iterator that yields all assigned scripts.

pub fn set_enabled(&mut self, enabled: bool)

Enables or disables scene node. Disabled scene nodes won’t be updated (including scripts) or rendered.

Important notes

Enabled/disabled state will affect children nodes. It means that if you have a node with children nodes, and you disable the node, all children nodes will be disabled too even if their Self::is_enabled method returns true.

pub fn is_enabled(&self) -> bool

Returns true if the node is enabled, false - otherwise. The return value does not include the state of parent nodes. It should be considered as “local” enabled flag. To get actual enabled state, that includes the state of parent nodes, use Self::is_globally_enabled method.

pub fn is_globally_enabled(&self) -> bool

Returns true if the node and every parent up in hierarchy is enabled, false - otherwise. This method returns “true” enabled flag. Its value could be different from the value returned by Self::is_enabled.

pub fn root_resource(&self) -> Option<Resource<Model>>

Returns a root resource of the scene node. This method crawls up on dependency tree until it finds that the ancestor node does not have any dependencies and returns this resource as the root resource. For example, in case of simple scene node instance, this method will return the resource from which the node was instantiated from. In case of 2 or more levels of dependency, it will always return the “top” dependency in the dependency graph.
