Laser Beamos script

Instead of a stream of fireballs, it draws a line and a beam end. But I've run across a few problems. The beamos won't start his laser jet. Also note the commented Line function. I can't figure out how to get it through the compiler, so I commented it out.

Anyway:

//-----Scripts for Beamos-----
// When you are close enough, the beamos shoots
// a laser at you. It draws a line representing
// a laser shot from the beamos's eye. A damage
// combo represents the tip of the laser.
//----------------------------
import "std.zh"
//-----BeamosEye-----
// This half determines when the beam should be fired
//
// D0 = The radius of the beamos's sight
// D1 = The delay (in frames) waited before firing (I'd recommend 20)
//-------------------
ffc script BeamosEye{
	void run(float radius, int maxdelay){
		int currentdelay = 0; 	  // delay waited
		bool delaystart = false;	// flag for start of delay
		float xdist;				// used to find how close Link is
		float ydist;				// same
		float hdist;				// distance between Link and Eye
		Screen->D[0] = 0;	       // link's xy position
		Screen->D[1] = 0; 	  	// tells whether link is close enough
		Screen->D[2] = this->X + ((this->Y/100)/100) + 8.0008; // xy of eye
		while(true){
			xdist = this->X - Link->X;
			ydist = this->Y - Link->Y;
			hdist = Sqrt(Pow(xdist, 2) + Pow(ydist, 2));
			// ^Distance formula^
			if((hdist <= radius) && (!delaystart)){
				Trace(9);
				Screen->D[0] = Link->X + ((Link->Y/100)/100);
				delaystart = true;
				currentdelay = 0;
			} //end if
			if((hdist > radius) && (Screen->D[1] == 1) || (delaystart)){
				Screen->D[1] = 0;
				delaystart = false;
			} //end if
			if(delaystart){
				currentdelay += 1;
			} //end if
			if(currentdelay == maxdelay){
				Screen->D[1] = 1;
				
			} //end if
			Waitframe();
		} //end while
	} //end void
} //end ffc script
//--------Beam-------
// This half draws the beam and follows Link
//
// D0 = Speed of the travelling beam
// D1 = Color of the beam
// D2 = Combo to be changed to when active
//-------------------
ffc script Beam{
	void run(float speed, float beamcolor, int activecombo){
		int passivecombo = this->Data; // combo for inactive beam
		bool active = false;	// flag determining whether this is active
		float xdist;			// xdelta of target

			// activation device
			if((Screen->D[1] == 1) && (!active)){
				this->X = Floor(Screen->D[0]);
				this->X = Ceiling(Screen->D[0]) * 100 * 100;
				active = true;
				this->Data = activecombo;
			} //end if
			// moving device / line draw-er
			if(active){
				xratio = 1;
				yratio = 1;
				xdist = Link->X - this->X;
				ydist = Link->Y - this->Y;
				if(xdist > ydist){
					xratio = xdist / ydist;
				} // end if				
				if(xdist <= ydist){
					yratio = ydist / xdist;
				} // end if
				hratio = Sqrt(Pow(xratio, 2) + Pow(yratio, 2));
				xratio = xratio / hratio;
				xratio = xratio * speed;
				yratio = yratio / hratio;
				yratio = yratio * speed;
				this->Vx = xratio;
				this->Vy = yratio;
				tempxy = this->X + ((this->Y/100)/100) + 8.0008;
				//Line(tempxy, beamcolor, Screen->D[2], 3, 1, false, 0, 0, 0);
			} //end if
			// deactivation device
			if((Screen->D[1] == 0) && (active)){
				this->Vx = 0;
				this->Vy = 0;
				this->X = 0;
				this->Y = 0;
				active = false;
				this->Data = passivecombo;
			} //end if
			Waitframe();
		} //end while
	} //end void
} //end ffc script

What am I doing wrong?
