components

mixer-control

Adds a click listener to an element to set aframe-extras/mesh-mixer on a model

<a-entity mixer-control="model: #model; clip: walkcycle"></a-entity>

property	type	default	usage
model	selector	null	the model to set animations for
clip	string	*	which clip to play on click

layered-material

Creates two lambert materials and blends them based on an alpha derived from a canvas

split-mesh

extracts sub-objects from models and attaches them to entities

<a-entity id="gltf" gltf-model="assets/my-model.glb"></a-entity>
<a-entity split-mesh="model: #gltf; name: subModel; map: mesh"></a-entity>

property	type	default	usage
model	selector	null	the model to split up
name	string	null	the name of the sub-object, typically named in a 3d software like Blender
map	string	'mesh'	optional - the name in <a-entity>.object3DMap

portal

requires camera component. renders view from another camera in scene to a texture

<a-entity id="cctv" camera="fov: 120; active: false;" spectator="screen: #tv; fps: 25;"></a-entity>
<a-entity id="tv" geometry="primitive: plane;"></a-entity>

property	type	default	usage
screen	selector	null	the entity to apply the screen to
fps	number	30.00	the refresh rate of the screen texture. Increasing this number impacts performance

aabb

a very simple collision detection system

<a-entity id='cube' aabb="
    moves: true;
    enabled: true;
    autoRefresh: true;
    bounds: proxy;
    interval: 40;
    belongsTo: group1, group 3;
    collidesWith: group2;
    predict: true
"></a-entity>

property	type	default	usage
enabled	boolean	true	whether the object is considered for collision by other objects
autoRefresh	boolean	true	when object is moving, collision boundary is also updated
size	vec3	0.25 0.25 0.25	When bounds is 'box' or 'subproxy', sets the dimensions of the object in meters width x height x depth
bounds	string	proxy	how the shape of the AABB is computed. supports box,mesh, proxy and subproxy
offset	vec3	0 0 0	move the aabb collider relative to local position
interval	number	20	Number of miliseconds between collision checks. Low numbers are allow more accurate collision, higher numbers are more performant.
belongsTo	array	none	The groups to which this AABB belongs.
collidesWith	array	none	A list of groups to check for collision against.
predict	boolean	true	Test for collisions a frame ahead for more precise collision detection.
