So i made a KnockBack sistem but it's just off

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 would just like some feedback from someone about the knockback sistem that i made here, it just seems off.

  2. What is the issue? Include screenshots / videos if possible!
    Probably there are some issues in regarding the whole writing of the script and also the way i detect the force based on the percentage of the script.So will be grateful to everyone that would take some time to check the script.I was trying to imitate the knockback sistem from the TSB or the Project Smash

  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    Tried rewriting it a whole lot of times, but this is the best i was able to achieve so far.

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!

Please do not ask people to write entire scripts or design entire systems for you. If you can’t answer the three questions above, you should probably pick a different category.
