What do you want to achieve?
I want to upgrade this script for my games and other people, this script is used for certain tools when inserted inside, this script like Tools follows Mouse. It use to easily shoot in first person.
- I just want you guys to upgrade this script and remove all that bugs -
-
What is the issue?
Bugs: when I reset my avatar it always removes the script or doesn’t work with the tools I had inserted the script and head players will float when using tools, animations not looking good when using this script; 2 arms do always not follow the mouse, 1 move 1 not, and when load morph for a certain team too.

Proof/Pictures(Bugs):
2 Arms bug with animations
Reset bug
Load morph bug
Head float
Need it work like this
Follow mouse when using tool
Reset

What solutions have you tried so far?
I tried many ways like removing some parts of the script, and changing types of scripts,…But still, nothing change
