Struct GltfAsset 

pub struct GltfAsset {
    pub models: Vec<(Handle<Mesh>, Handle<PbrMaterial>)>,
    pub conditions: Vec<Option<ModelCondition>>,
    pub geometry: Vec<Arc<MeshGeometry>>,
    pub bbox: MeshBbox,

    pub lights: Vec<GltfLight>,
    /* private fields */
}

Representation of a 3D GLTF model asset. This will spawn the model and return the parent entity ID. See the crate documentation for usage examples.

Fields

models: Vec<(Handle<Mesh>, Handle<PbrMaterial>)>

The list of parsed glTF models. Each model is represented by a mesh and its associated material.

conditions: Vec<Option<ModelCondition>>

Connection condition of each entry of Self::models (None = always shown).

geometry: Vec<Arc<MeshGeometry>>

Triangles of each entry of Self::models, kept on the CPU (e.g. for navigation): the meshes themselves leave the main world once uploaded to the GPU.

bbox: MeshBbox

The englobing bounding box of the entire model, computed from the bounding boxes of all meshes.

properties: HashMap<String, (Vec3, Vec3)>

Named properties (e.g. spawn points) extracted from meshes whose name starts with %P%. These meshes are not added to Self::models; only their name, position and scale are kept here.

bones: Vec<GltfBone>

Bones of a rigged model (nodes named %B%<bone>), parents first.

model_bones: Vec<Option<usize>>

Bone each entry of Self::models moves with (its vertices are then relative to the bone).

animations: HashMap<String, Handle<AnimationClip>>

Animation clips of the bones, by name.

lights: Vec<GltfLight>

Lights of the model, spawned with it (see Self::spawn_lights).

Implementations

impl GltfAsset

pub fn animation(&self, name: &str) -> Option<&Handle<AnimationClip>>

pub fn spawn_lights(&self, commands: &mut Commands<'_, '_>, parent: Entity)

Spawns the lights of the model under parent, following its transform.

pub fn models_where( &self, connected: impl Fn(&str) -> bool, ) -> impl Iterator<Item = &(Handle<Mesh>, Handle<PbrMaterial>)>

Models whose connection condition holds, connected telling whether an anchor is connected.
