RenderComponent(system, entity) 

Create a new RenderComponent.

Parameters

system	RenderComponentSystem	The ComponentSystem that created this Component.
entity	Entity	The Entity that this Component is attached to.

Asset, numberasset 

The render asset for the render component (only applies to type 'asset') - can also be an asset id.

numberbatchGroupId 

Assign meshes to a specific batch group (see BatchGroup). Default is -1 (no group).

booleancastShadows 

If true, attached meshes will cast shadows for lights that have shadow casting enabled.

booleancastShadowsLightmap 

If true, the meshes will cast shadows when rendering lightmaps.

BoundingBoxcustomAabb 

If set, the object space bounding box is used as a bounding box for visibility culling of attached mesh instances. This is an optimization, allowing oversized bounding box to be specified for skinned characters in order to avoid per frame bounding box computations based on bone positions.

booleanisStatic 

Mark meshes as non-movable (optimization).

number[]layers 

An array of layer IDs (Layer#id) to which the meshes should belong. Don't push, pop, splice or modify this array, if you want to change it - set a new one instead.

booleanlightmapped 

If true, the meshes will be lightmapped after using lightmapper.bake().

numberlightmapSizeMultiplier 

Lightmap resolution multiplier.

Materialmaterial 

The material Material that will be used to render the meshes (not used on renders of type 'asset').

Asset[], number[]materialAssets 

The material assets that will be used to render the meshes. Each material corresponds to the respective mesh instance.

MeshInstance[]meshInstances 

An array of meshInstances contained in the component. If meshes are not set or loaded for component it will return null.

booleanreceiveShadows 

If true, shadows will be cast on attached meshes.

numberrenderStyle 

Set rendering of all MeshInstances to the specified render style. Can be:

• RENDERSTYLE_SOLID
• RENDERSTYLE_WIREFRAME
• RENDERSTYLE_POINTS

Defaults to RENDERSTYLE_SOLID.

EntityrootBone 

A reference to the entity to be used as the root bone for any skinned meshes that are rendered by this component.

stringtype 

The type of the render. Can be one of the following:

• "asset": The component will render a render asset
• "box": The component will render a box (1 unit in each dimension)
• "capsule": The component will render a capsule (radius 0.5, height 2)
• "cone": The component will render a cone (radius 0.5, height 1)
• "cylinder": The component will render a cylinder (radius 0.5, height 1)
• "plane": The component will render a plane (1 unit in each dimension)
• "sphere": The component will render a sphere (radius 0.5)
• "torus": The component will render a torus (tubeRadius: 0.2, ringRadius: 0.3)

hide() 

Stop rendering MeshInstances without removing them from the scene hierarchy. This method sets the MeshInstance#visible property of every MeshInstance to false. Note, this does not remove the mesh instances from the scene hierarchy or draw call list. So the render component still incurs some CPU overhead.

show() 

Enable rendering of the component's MeshInstances if hidden using RenderComponent#hide. This method sets the MeshInstance#visible property on all mesh instances to true.

booleanenabled 

Enables or disables the component.

Entityentity 

The Entity that this Component is attached to.

ComponentSystemsystem 

The ComponentSystem used to create this Component.

fire(name, [arg1], [arg2], [arg3], [arg4], [arg5], [arg6], [arg7], [arg8]) 

Fire an event, all additional arguments are passed on to the event listener.

obj.fire('test', 'This is the message');

Parameters

name	string	Name of event to fire.
arg1	*	First argument that is passed to the event handler.
arg2	*	Second argument that is passed to the event handler.
arg3	*	Third argument that is passed to the event handler.
arg4	*	Fourth argument that is passed to the event handler.
arg5	*	Fifth argument that is passed to the event handler.
arg6	*	Sixth argument that is passed to the event handler.
arg7	*	Seventh argument that is passed to the event handler.
arg8	*	Eighth argument that is passed to the event handler.

Returns

EventHandler

Self for chaining.

hasEvent(name) 

Test if there are any handlers bound to an event name.

obj.on('test', function () { }); // bind an event to 'test'
obj.hasEvent('test'); // returns true
obj.hasEvent('hello'); // returns false

Parameters

name

string

The name of the event to test.

Returns

boolean

True if the object has handlers bound to the specified event name.

off([name], [callback], [scope]) 

Detach an event handler from an event. If callback is not provided then all callbacks are unbound from the event, if scope is not provided then all events with the callback will be unbound.

const handler = function () {
};
obj.on('test', handler);

obj.off(); // Removes all events
obj.off('test'); // Removes all events called 'test'
obj.off('test', handler); // Removes all handler functions, called 'test'
obj.off('test', handler, this); // Removes all handler functions, called 'test' with scope this

Parameters

name	string	Name of the event to unbind.
callback	HandleEventCallback	Function to be unbound.
scope	object	Scope that was used as the this when the event is fired.

Returns

EventHandler

Self for chaining.

on(name, callback, [scope]) 

Attach an event handler to an event.

obj.on('test', function (a, b) {
    console.log(a + b);
});
obj.fire('test', 1, 2); // prints 3 to the console

const evt = obj.on('test', function (a, b) {
    console.log(a + b);
});
// some time later
evt.off();

Parameters

name	string	Name of the event to bind the callback to.
callback	HandleEventCallback	Function that is called when event is fired. Note the callback is limited to 8 arguments.
scope	object	Object to use as 'this' when the event is fired, defaults to current this.

Returns

EventHandle

Can be used for removing event in the future.

once(name, callback, [scope]) 

Attach an event handler to an event. This handler will be removed after being fired once.

obj.once('test', function (a, b) {
    console.log(a + b);
});
obj.fire('test', 1, 2); // prints 3 to the console
obj.fire('test', 1, 2); // not going to get handled

Parameters

name	string	Name of the event to bind the callback to.
callback	HandleEventCallback	Function that is called when event is fired. Note the callback is limited to 8 arguments.
scope	object	Object to use as 'this' when the event is fired, defaults to current this.

Returns

EventHandle

• can be used for removing event in the future.
