RigidBodyComponentSystem(app) 

Create a new RigidBodyComponentSystem.

Parameters

app

pc.Application

The Application.

pc.Vec3gravity 

The world space vector representing global gravity in the physics simulation. Defaults to [0, -9.81, 0] which is an approximation of the gravitational force on Earth.

raycastFirst(start, end) 

Raycast the world and return the first entity the ray hits. Fire a ray into the world from start to end, if the ray hits an entity with a collision component, it returns a pc.RaycastResult, otherwise returns null.

Parameters

start	pc.Vec3	The world space point where the ray starts.
end	pc.Vec3	The world space point where the ray ends.

Returns

pc.RaycastResult

The result of the raycasting or null if there was no hit.

contact 

Fired when a contact occurs between two rigid bodies.

Parameters

result

pc.SingleContactResult

Details of the contact between the two bodies.

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	object	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

pc.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.

var 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 hander functions, called 'test' with scope this

Parameters

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

Returns

pc.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

Parameters

name	string	Name of the event to bind the callback to.
callback	pc.callbacks.HandleEvent	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

pc.EventHandler

Self for chaining.

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	pc.callbacks.HandleEvent	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

pc.EventHandler

Self for chaining.
