Struct bevy::prelude::TransformBundle

pub struct TransformBundle {
    pub local: Transform,
    pub global: GlobalTransform,
}

A Bundle of the Transform and GlobalTransform Components, which describe the position of an entity.

• To place or move an entity, you should set its Transform.
• To get the global transform of an entity, you should get its GlobalTransform.
• For transform hierarchies to work correctly, you must have both a Transform and a GlobalTransform.
  • You may use the TransformBundle to guarantee this.

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 by systems in the system set TransformPropagate.

This system runs during PostUpdate. If you update the Transform of an entity in this schedule or after, you will notice a 1 frame lag before the GlobalTransform is updated.

Fields

local: Transform

The transform of the entity.

global: GlobalTransform

The global transform of the entity.

Implementations

impl TransformBundle

pub const IDENTITY: TransformBundle = _

An identity TransformBundle with no translation, rotation, and a scale of 1 on all axes.

pub const fn from_transform(transform: Transform) -> TransformBundle

Creates a new TransformBundle from a Transform.

This initializes GlobalTransform as identity, to be updated later by the PostUpdate schedule.
