Line drawing tool

Published by request. Draws lines using Chompy's and Sales' DrawLine() function. Hold ctrl and drag yer mouse through Graal, wee~

PHP Code:
//#CLIENTSIDE
function onCreated() {
  
this.draw = false;
  
this.ox = nil;
  
this.oy = nil;
  
this.iIndex = 0;
}

// erase drawn lines
function onEraseLines()
  
hideImgs(0, 199);

// mouse stuff
function GraalControl.onMouseDown(kmod) {
  if (
kmod in |4, 8|) { // ctrl
    
this.draw = true;
    
this.ox = mousex;
    
this.oy = mousey;
    
    
cancelEvents("EraseLines");
  }
}

function 
GraalControl.onMouseUp() {
  if (!
this.draw)
    return;
  
  
this.draw = false;
  
cancelEvents("EraseLines");
  
scheduleEvent(3, "EraseLines", nil);
}

function 
GraalControl.onMouseDragged() {
  if (!
this.draw)
    return;
  
  
temp.dx = abs(this.ox - mousex);
  
temp.dy = abs(this.oy - mousey);
  
temp.d  = (temp.dx ^ 2 + temp.dy ^ 2) ^ 0.5;
  if (
temp.d > 0.1) {
    
temp.i = this.iIndex;
    
temp.t = 0.5;
    
    
DrawLine(temp.i, this.ox, this.oy, mousex, mousey, 2 / 16);
    
changeImgColors(temp.i, 1, 1, 1, 1);
    
changeImgVis(temp.i, 3);
    
    
this.iIndex++;
    
this.iIndex %= 200;
    
    
this.ox = mousex;
    
this.oy = mousey;
  }
}

function DrawLine(idx, sx, sy, tx, ty, w) {

showPoly(idx,
    { 
sx, sy,
      
tx, ty,
      
tx + cos(ang) * w, ty - sin(ang) * w,
      
sx + cos(ang) * w, sy - sin(ang) * w  });
}
