How do i make a roblox Executer?

If you don't know anything, don't start with Roblox. That's a tough game to start with. In fact, don't start with any game. Start with understanding how your operating system works, then pick a low level systems programming language to learn. After that, you can start learning how to make cheats.

1. Learn the basics of your computer. These are some key points you'll need to understand, along with resources:
   
   - What is systems programming?
      The primary mechanism in your cheat is mainly virtual memory manipulation.
      https://en.wikipedia.org/wiki/Systems_programming
   
   - How does a CPU work?
      You're going to be working with primitives. You need to understand how your CPU works.
      https://en.wikipedia.org/wiki/Central_processing_unit#Operation
   
   - What is disassembly and where is it useful?
      Disassembly breaks down instructions that a CPU understands into something humans can read.
      https://en.wikibooks.org/wiki/X86_Disassembly
   
   - What is virtual memory?
      If you're making cheats, understanding what virtual memory is and how it works is non-negotiable.
      https://en.wikipedia.org/wiki/Virtual_memory
   
   - How does a compiler work with primitive structures?
      This will carry on from your knowledge of a systems programming language like C. Google also exists and is very useful for questions like these.

2. Learn OS theory and how Windows works specifically

- To understand processes, threads, and the Windows API:
   https://learn.microsoft.com/en-us/sysinternals/resources/windows-internals

- Information on disassembly, obfuscation, and system internals:

   https://www.amazon.com/Practical-Reverse-Engineering-Reversing-Obfuscation/dp/1118787315

3. Learn your programming language of choice. C is solid and doesn't require you to jump hoops:

- Choose a solid development environment for C/C++ programming:
   https://visualstudio.microsoft.com/downloads/

- Learn the basics, then go deeper afterwards:
   https://www.learn-c.org/

4. Tools I'll throw out that are helpful once you learn the basics:

- Cheat Engine:
   Learn how to use this on a simple game like AssaultCube. Get comfortable with making basic cheats

   https://www.cheatengine.org/

- Reclass.NET:
   This helps you analyze memory in real-time

   https://github.com/ReClassNET/ReClass.NET

- Binary Ninja:
   Solid choice for disassembly and decompilation
   https://binary.ninja/

- Scylla
   Dumps modules in processes. More advanced, will be needed for some games
   https://github.com/NtQuery/Scylla

5. Most importantly: You need to want to learn more.

If you're not interested in learning anything, you won't get far. You need to have disciplined learning in order to understand what you're doing. A lot of people think that AI can get you there. It can't always do it. An AI agent can sometimes make something that works, but it's not going to be useful to you if you don't know what you're doing. This is a niche section of programming, and with Roblox it can get super niche. Keep that in mind.

That should get you started, but I'm not going to pretend like making a game cheat from scratch is something you can simply accomplish. You need to understand the fundamentals in order to accomplish this, and trying shortcuts will lead to failure.

What I listed are your fundamentals. There's plenty of guides online that should help you once you get ahold of the basics, or talk to me once you figure out the basics. I can point you in the right direction. GuidedHacking is a good place to start after the fundamentals are covered.
