Creating a weapon and attaching it on a vehicle

[Noah_Antilles]

Hello there,

I've been trying to create a weapon (uzi) and attach it on a vehicle (hydra) the weapon should fire when I click the left mouse button.

I am stuck at the very beginning of the script (trying to get the uzi to spawn) and I just cannot progress any further.

function hydraGuns()
    local vehicle = getPedOccupiedVehicle(localPlayer)
    if(vehicle)then
        if getElementModel(vehicle) == 520 then
            local x, y, z = getElementPosition(vehicle)
            local weapon = createWeapon("uzi", x, y, z)
			outputChatBox ("Hydra guns are installed")
        end
    end
end

What am I doing wrong?

Is hydraGuns() ever called? Maybe make it on a command or attach it to onClientVehicleEnter

Thanks for your reply,

as far as I can see the uzi should spawn when I enter a Hydra. On one point I actually managed to have the uzi spawn, but soon after it didn't work anymore.

would it be better to have the uzi spawn when I press left mouse?

Spawning a weapon doesn't make it fire.

You can use the function setWeaponState (theWeapon, "firing") to make it fire (i.e when you press the left mouse button)

I know spawning a weapon doesn't make it fire, but since I am a beginner I try to make my script in little steps.

First try to spawn the weapon > try to attach it to the vehicle > make it fire on left click.

Right now I am stuck on spawning the weapon, that's why I asked for help

After creating the weapon attach it to the Hydra with attachElements

Thanks for your reply but you´re giving me tips on my next step which I haven´t reached yet.

Right now I am trying to get the uzi to spawn, but it doesn´t work for some reason. 

I think the problem might be that the uzi spawns somewhere, but not on the x,y,z coordinates of the player/vehicle.

What could the problem be that the uzi doesn´t spawn?

Is that your full code (the one you posted)? If so, you never attached that function to an eventHandler. How would MTA know, you want that piece of code to run when the player enters a hydra?

Oh of course I am a retard. I totally forgot that.

I got it working now, an uzi spawns and is attached to the Hydra. Now I will try to make it fire on left mouse button

Thanks for helping me!
