Hello Guys, i'm working on this new script its a Mounted machine gun and i faced some problems, so first problem is in the `getOut` function supposed to make the player free by that i mean (detach the player from the minigun and the turret object `a minigun` and back to normal) and the second problem is, in drawin a crosshair for the weapon as you can see in the line [75] of the code it supposed to `drawImage`. but it does not < maybe i'm mistaken in writing the `drawImage` function under those lines of `cursorX` statement, if so please enlighten me

and last but not least i want the `Weapon` to appear so i probably remove the `SetElementAlpha` to zero and replace the Weapon Model with a realistic weapon (i.e MG42) so, is this can be accomplish ? replacing the actual minigun weapon with another one? i tried to use 

function m42()
txd = engineLoadTXD("m4.txd", 31)
engineImportTXD(txd, 31)
dff = engineLoadDFF("m4.dff", 31)
engineReplaceModel(dff, 31)
end
--i guess the Weapon Model is 356 i tried with it but it didn't change the wepaon

but its the same and if could replace the weapon how can i avoid the firing Rotation problems. because i think the weapon firing Rotation is already buggy. i really need this to work, beacuse i want to prove to myself that i'm capable of learning.

You can attach an object to the weapon (same model) and set the opacity of the weapon-element to 0. This way you can change the attach offset in depended.
