Struct bevy_transform::components::GlobalTransform [−][src]
Expand description
Describe the position of an entity relative to the reference frame.
- To place or move an entity, you should set its
Transform
. - To be displayed, an entity must have both a
Transform
and aGlobalTransform
. - To get the global position of an entity, you should get its
GlobalTransform
.
Transform
and GlobalTransform
Transform
is the position of an entity relative to its parent position, or the reference
frame if it doesn’t have a Parent
.
GlobalTransform
is the position of an entity relative to the reference frame.
GlobalTransform
is updated from Transform
in the system
transform_propagate_system
.
In pseudo code:
for entity in entities_without_parent:
set entity.global_transform to entity.transform
recursively:
set parent to current entity
for child in parent.children:
set child.global_transform to parent.global_transform * child.transform
This system runs in stage CoreStage::PostUpdate
. If you
update theTransform
of an entity in this stage or after, you will notice a 1 frame lag
before the GlobalTransform
is updated.
Fields
translation: Vec3
rotation: Quat
scale: Vec3
Implementations
Creates a new identity GlobalTransform
, with no translation, rotation, and a scale of 1
on all axes.
Returns the 3d affine transformation matrix from this transforms translation, rotation, and scale.
Equivalent to -local_x()
Equivalent to -local_y()
Equivalent to [-local_z()
