Hello all,

I am playing aroun with one of my old Sigil demos. I was trying to make it so you can move the sprite around using the arrow keys, which I have accomplished. However I can't keep the sprite from going off the screen. Here is my code. Any help is appericated.

without type_check 
 
include std/machine.e 
include EuSigil.ew 
 
constant WIDTH = 640, HEIGHT = 480 
 
slWindow(WIDTH,HEIGHT,"Sprite Example",0) 
 
atom x = WIDTH / 2 
atom y = HEIGHT / 2 
 
integer spr = slLoadTexture("Stick.png") 
 
if spr = -1 then 
	puts(1,"Failed to load sprite!\n") 
	abort(0) 
end if 
 
while not slShouldClose() do 
 
    slSetBackColor(255,255,255) --change background to white 
 
	if slGetKey(SL_KEY_ESCAPE) = 1 then 
		slClose() 
	end if 
	 
	if slGetKey(SL_KEY_LEFT) = 1 then 
		x -= 2 
		slSprite(spr,x,y,32,32) 
		elsif x  and WIDTH <= 0 then 
			x *= 2 
			slSprite(spr,x,y,32,32) 
	end if 
	 
    slSprite(spr,x,y,32,32) 
	 
   slRender() 
    
end while 
 
slClose()
