Instead of image[pl] use img[pl].

for pl = 1,32 do
image[pl] = {x = 0,y = 0,id = 0}
end

that wont work, didn't work for me too, you have to place it inside function.

img[id].i=image("gfx/weapons/bomb.bmp",x,y,0)
img[id].x = x
img[id].y = y
end
end
end

I think it will work, didn't test it maybe some ends are missing.

But you won't be able to freeimage.

img[pl] = {x = 0, y = 0, i = 0}

instead of images[pl] = ...
It's i, not id.

eww your code won't really work anyway. And I wouldn't use The Camo's code either, it'll totally screw everything up.

1:
Suppose I just joined the server and immediately press F2. The server will try to remove my image (img[myid].i), but it will come across a nil value as the image has not been created yet. Result: error.

2:
That will be fixed with what Yasday said. Still, you might come across some trouble there, you'd better check if an image has been created already.

3:
Anyone can just spawn bombs. I think you want to prevent that with your 'air' function, don't you?

4:
Please read the info.txt carefully.

info.txt has written

x<=0: do not rotate with player, x>0: rotate img with player
y<=0: only draw if not covered by fog of war, y>0: draw always

x and y do not represent the location of the image. Use cs2d lua cmd

imagepos for this.

5:
I might still miss a few things in there, but I'll also cover The Camo's function:
Every time someone presses F2, all the image data of all players will be overwritten. This will create a huge amount of useless pictures with lost id's so they're hard to remove and it can only be done manually.

+ he puts an end at the wrong position; it will now try to free the image (of which the id has just been overwritten), create a new one (once again overwriting the id) and set the x and y 32 times. That means 32 images for each keypress! Madness!
