I was asked to make a chopshop system, and I know how to do the internal stuff but I'm completely stumped on how to start it. Any help? Like how do I start the script? ENUm's, etc?
Well, seeing that you must first know how to script pawno (SA-MP Code) I recommend seeing the sa-mp wiki: https://sampwiki.blast.hk/
Next, I would consider either learning Y_INI or MySQL.
Now, if you followed those steps you should find this easy;
1. Create a basic registration/login system using Y_INI or MySQL.
2. Create a saving system either using Y_INI or MySQL to store the information.
3. Get some simple includes ZCMD.
