Devilish Particles

Hi,

some devilish particles for Christmas.

Code: [Select]

screen(640,480,0,"Particles")
backcolor(0,0,0)
setframetimer(60)
mousehide()

function distance(x1,y1,x2,y2)
   local dx, dy
   dx=x1-x2
   dy=y1-y2
   return math.sqrt(dx*dx+dy*dy)
end

function xMove(x3,w,s)
  return x3 + cosin[w]*s
end

function yMove(y3,w,s)
  return y3 + sinus[w]*s
end

function rand(minZahl,maxZahl)
  maxZahl=(maxZahl-minZahl)
  return int(rnd()*maxZahl+minZahl)
end

anzahl,i,aSpeed,xscreen,yscreen = 1000,0,0,640,480

What about a mousehide() ?
