Weird First Person Body Glitch

Help and Feedback Scripting Support

#1

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!
    I’m making a first person body script, where you can toggle first person and third person.

  2. What is the issue? Include screenshots / videos if possible!
    In third person it works perfectly fine, but when I go into first person, my collisions mess up and I can walk through walls.

  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    I have tried asking ChatGPT to view my script, but the solutions it tried didn’t work.

After that, you should include more details if you have any. Try to make your topic as descriptive as possible, so that it’s easier for people to help you!
