Ok.. i´m working on a template Project for my workshop. But got a little Problem...

I created a Level. inside is a straigth way, with a little half-pipe at the end. The way and the pipe are made of 13 plates. The pipe is built of 6 models. each has a higher roll-value ( to rotate it to a half-pipe ).

Now i created a ball on the way. i want the ball to fly straight on, ask for the pipe-plates roll value.. and set the balls own tilt to the you.roll

Problem:
i´m tracing below the hero:
Code:
action player_action()
{
	player = my;
	wait(1);
	c_setminmax(my);
	while(1)
	{
		c_trace(my.x,vector(my.x,my.y,my.z-9999),IGNORE_ME);
		if(you != NULL){my.tilt = you.roll;}
		
		if(key_a == 1){c_move(my,vector(1*time_step,0,0),nullvector,GLIDE);}
		
		vec_set(camera.x, vector(my.x,my.y-400,my.z));
		wait(1);
	}
}


ok.. works fine. The plate gives his roll-value to the ball. BUT.
Now the tilt of the ball is 15 ( the roll-value of the 1st pipe-plate ).
But the c_trace is scanning straight down... How to say the tracing, to trace into the new direction?
