Constructor Details

RRayCast

public RRayCast(RVec3Arg startLocation,
 Vec3Arg offset)

Instantiate a ray cast with the specified endpoints.

Parameters:

startLocation - the desired start location (not null, unaffected)

offset - the desired end offset from the start (not null, unaffected)

Method Details

getDirection

public Vec3 getDirection()

Copy the end offset. The ray cast is unaffected. (native attribute: mDirection)

Returns:

a new offset vector (relative to the start location)

getOrigin

public RVec3 getOrigin()

Copy the start location. The ray cast is unaffected. (native attribute: mOrigin)

Returns:

a new location vector

getPointOnRay

public RVec3 getPointOnRay(float fraction)

Return a point on the ray with the specified fraction. The ray cast is unaffected.

Parameters:

fraction - (0→start of ray, 1→end of ray)

Returns:

a new location vector
