Physics Test

Room Creation Code:
{
    physics_create_world( room , 0 , 0 , room_width , room_height , 32 );
    repeat( 20 )
    {
        instance_create( random( room_width ) , random( room_height ) , objBall );
    }
}
objBall Create:
{
    direction = random( 360 );
    speed = 10;
    friction = 0.1;
}
objBall Collide with objBall:
{
    with other
    {
        physics_apply_force( other.x , other.y , other.hspeed , other.vspeed );
    }
}
