Detailed Description

Helper object for gameplay physical forces.

PhysicsForces can be created and "attached" to other PhysicsBodies to attract them to the position of the PhysicsForce.

Member Function Documentation

void PhysicsForce::attach	(	Point3F	start,
		Point3F	direction,
		float	maxDist
	)

Attempts to associate the PhysicsForce with a PhysicsBody.

Performs a physics ray cast of the provided length and direction. The PhysicsForce will attach itself to the first dynamic PhysicsBody the ray collides with. On every tick, the attached body will be attracted towards the position of the PhysicsForce.

A PhysicsForce can only be attached to one body at a time.

Note:

To determine if an attach was successful, check isAttached() immediately after calling this function.n

void PhysicsForce::detach

(

Point3F

force = Point3F::Zero

)

Disassociates the PhysicsForce from any attached PhysicsBody.

Parameters:

force

Optional force to apply to the attached PhysicsBody before detaching.

Note:

Has no effect if the PhysicsForce is not attached to anything.

bool PhysicsForce::isAttached

(

)

Returns true if the PhysicsForce is currently attached to an object.
