Hey you all. I’m currently trying to get a first person script to work while the player can see their own character (With the right camera placement), but when I sprint, the camera goes behind the player for some reason, making it turn into 3rd person. Even when I’m idle, the camera is placed slightly behind the character, which makes it look weird.
After I turn on transparency modifiers for the character, I noticed that this was happening with the camera, because I could actually see the character of course.
I’m asking here because this was a resource that I applied to my game.
I tried modifying the different CFrames, by modifying this value: (x, y, Here) where negative values were the only way to put the camera in place, which did place the camera a bit better, but for some reason the player’s character would constantly look backwards.
Also, when looking directly down, the character looks backward and forward constantly (Similar to how the negative values made the character look backwards), which is another issue.
Here’s an image of how the player’s view looks like:
While Idle:
While Running:
The credits to the scripts made by others are comments in the scripts.
So with that out of the way, here is the code:

Log:
- Changed the Sway effect to work on CameraOffset because it caused the player to rotate on Y axis since they were in first person.
- Changed line 65 [Cam.CameraType = Enum.CameraType.Scriptable] to .Custom
