Needing help with making a script

[Fsfan]

Hey guys,

I'm requesting help for a simple mod, for a bus to spawn somewhere and the objective is to do go to a certain location, get some passengers and then go to another location. After getting to that location the player gets money. I don't quite know how to start because I'm only a beginner at this I hope to build up and make a working bus mod for all with many missions!

Thanks,

Fsfan

I have a feeling you're asking someone to explain to you how to write a script from beginning to end. Unfortunately, the best way to learn how to do something is by trial and error.

 

With that said, I would like to donate a Tow Truck script I was working on. It's written for the Lua ScriptHook (not GTALua). I provide the source code in hopes that it will help you understand the very basics of what you need to do.

Hey, thanks for the reply and the lua script, you are right about the trial and error thing. I'm just a bit impatient on when I'm going to become as good as others LOL!

Cheers,

Don't use LUA, it's the worst, you can't use many functions/natives. Try using C#. Add me on Skype/Steam: jedijosh920 and I can send you a script or teach you.

Don't diss Lua, man! Blame the script hook guys for not keeping it updated
