Actions are used to continuously modify the state of particles created by an Emitter.

---

	Class	Description
	Accelerate	The Accelerate Action adjusts the velocity of the particle by a constant acceleration.
	AntiGravity	The AntiGravity action applies a force to the particle to push it away from a single point - the center of the effect.
	ApproachNeighbours	The ApproachNeighbours action applies an acceleration to the particle to draw it towards other nearby particles.
	BoundingBox	The BoundingBox action confines each particle to a box.
	Collide	The Collide action detects collisions between particles and modifies their velocities in response to the collision.
	DeathSpeed	The DeathSpeed action marks the particle as dead if it is travelling faster than the specified speed.
	DeathZone	The DeathZone action marks the particle as dead if it is inside a specific zone.
	Explosion	The Explosion action applies a force on the particle to push it away from a single point - the center of the explosion.
	Friction	The Friction action applies friction to the particle to slow it down when it's moving.
	GravityWell	The GravityWell action applies a force on the particle to draw it towards a single point.
	Jet	The Jet Action applies an acceleration to the particle only if it is in the specified zone.
	LinearDrag	The LinearDrag action applies drag to the particle to slow it down when it's moving.
	MatchRotateVelocity	The MatchRotateVelocity action applies an angular acceleration to the particle to match its angular velocity to that of its nearest neighbours.
	MatchVelocity	The MatchVelocity action applies an acceleration to the particle to match its velocity to that of its nearest neighbours.
	MinimumDistance	The MinimumDistance action applies an acceleration to the particle to maintain a minimum distance between it and its neighbours.
	Move	The Move action updates the position of the particle based on its velocity.
	MutualGravity	The MutualGravity Action applies forces to attract each particle towards the other particles.
	QuadraticDrag	The QuadraticDrag action applies drag to the particle to slow it down when it's moving.
	RandomDrift	The RandomDrift action moves the particle by a random small amount every frame, causing the particle to drift around.
	Rotate	The Rotate action updates the rotation of the particle based on its angular velocity.
	RotateToDirection	The RotateToDirection action updates the rotation of the particle so that it always points in the direction it is traveling.
	RotationalFriction	The RotationalFriction action applies friction to the particle's rotational movement to slow it down when it's rotating.
	RotationalLinearDrag	The RotationalLinearDrag action applies drag to the particle to slow it down when it's rotating.
	RotationalQuadraticDrag	The RotationalQuadraticDrag action applies drag to the particle to slow it down when it's rotating.
	ScaleAll	The ScaleAll action adjusts the size of the particles image, its collision radius and its mass as it ages.
	SpeedLimit	The SpeedLimit action limits the particle's maximum speed to the specified speed.
	TargetRotateVelocity	The TargetRotateVelocity action adjusts the angular velocity of the particle towards the target angular velocity.
	TargetVelocity	The TargetVelocity action adjusts the velocity of the particle towards the target velocity.
	TurnTowardsPoint	The TurnTowardsPoint action causes the particle to constantly adjust its direction so that it travels towards a particular point.
	TweenPosition	The TweenPosition action adjusts the particle's position between two locations as it ages.
	ZonedAction	The ZonedAction Action applies an action to the particle only if it is in the specified zone.
