Hi again,
I am done with a custom projecttile script.
The happy news is that the bullet even moves through walls.
So how can i detect the walls and bounce back or atleast prevent the bullet from moving futher when it meets a wall.

Here is the scrap:

addhook("attack","bbb")
function bbb(id)
local h = player(id,"x")
local j = player(id,"y")
		   img[id]=image("gfx/blabla.png",0,0,0) 
			imagepos(img[id],h , j,90)
			tween_move(img[id],500,screenx[id],screeny[id])
			timer(700,"freeimage",img[id])
end

screenx and screeny are client data positions. (who cares anyway.. :/)

You have to make an updating function (with ms100 or always hook, for example) to check if image of your projectile isn't moving through a wall atm. Try cs2d lua cmd tile.

And to make you know, 
object(imgid,"x")
and 
object(imgid,"y")
can be used in this case.

Otherwise, you gotta specify your own parameters for coordinates.

if tile(object(img[id],"x"),object(img[id],"y"),"wall") then

Oh, I forgot about something, if you're interested in a good code optimisation, read this. The post is two years old but you should check if it's still up-to-date.
