[HELP] Modify glue script to allow weapon switching.

[UTurn]

Since weapon switching can't be done while glued to a vehicle, I tried to modify a glue script made by uPrell.

I made 2 functions to change weapons that are bound to Q and E just as X is bound to 'glue'.

Somewhere online I read I could still set the players weapon slot so I thought it would work.

Either I made a simple mistake in the code or I'm going about this wrong.

Did plenty searching and couldn't find anything that could help.

Here is the modified script, if you could tell me what I'm doing wrong or how I could do this it'd be greatly appreciated.

        slot = slot - 1

The code doesn't throw any warnings or errors, but it doesn't do anything.

Thanks in advance for any help you can give.

Most of the time 70% of the slots are empty.

So the weapon won't be changed. (because you don't have a weapon in that slot)

Most of the time 70% of the slots are empty.

So the weapon won't be changed. (because you don't have a weapon in that slot)

So instead of just moving to the next slot, I need to check for the next slot that actually contains a weapon, and then set that slot? How can I check if a weapon slot actually contains a weapon? I looked through the ped functions in the wiki and I can only find a get and set method for the slot, I haven't found a function that can check the contents of a particular slot.

if getPedWeapon ( player,slot ) then 

[UTurn]

if getPedWeapon ( player,slot ) then 

Thank you IIYAMA, it's working perfect. Here's the code for anybody who does some searching on how to do this.
