If you want to make a mod menu in C++, use ScriptHookV, if you want in C#, VB and other languages, use ScriptHookVDotNet (that's what I use, I kinda used C# all the time and now I'm used to C# rather then C++). For making your own C# mod menu, you can start with a nativeui template, understand how submenus, buttons, checks, etc. work and also native functions, and then you can start adding buttons such as Invincible (this is the first one I started with). It's the easiest: Game.Player.Character.IsInvincible = true; . I'm not gonna give you any more code, since you want to make your own mod menu. It isn't that hard, you just gotta learn the basics like what bool means (false or true), what void means, what string means, etc. Btw, I'm also currently making a mod menu, I almost added all the features from other mod menus (ALMOST), and I got mp to sp cars working, just one line of code (won't tell it to anyone since I worked hard to discover that crap)
