Detailed Description

This area covers raycast functions. Set or get various raycast propertie.
Use as raycast.function()
These functions give access to basic raycasting that DOES NOT require
physics in order to work.

For more information on how these functions can be used please visit the User Manual - http://www.aurasoft-skyline.co.uk

Member Data Documentation

int ray::fx

raycast to center of screen.

Ray out from the center of the screen, similar to how and fps shoots, returns the world position of where it hits.

function onInit(objID)
    x,y,z = raycastToCenterScreen();
end

int ray::x

raycast from object.

ray from a position in direction of dir_xyz

function onInit(objID)
    x,y,z = raycastFromObject(objx,objy,objz, dirx,diry,dirz);
end

int ray::y = getHeightOffGround(objx,objy,objz)

get height off ground.

ray fired down and check for objects below and returns y distance

function onInit(objID)
    y = getHeightOffGround(objx,objy,objz);
end

int ray::z = raycastToCenterScreen()
