//Laser Script by TemplarGFX
//This script is used to check for collisions over
//a distince in a direction in a single step.
//It returns either the distance travelled before
//hitting a blocking object, the id of the enemy we hit,
//or 0 if no collision occurs

//argument0 = direction to shoot
//argument1 = max distance to shoot
//argument2 = object you want to damage
//argument3 = blocking object
//argument4 = precision (1<->argument1)

//returns 0 : no collision
//returns -distance : distance to colliding point for blocking object (negative value)
//returns id : id of object to damage
