Need help with combat system - note that I used shiftkey as an example of the function name

Help and Feedback Scripting Support
#1
  1. What do you want to achieve? Keep it simple and clear!
    I want to make a script where when a player presses V, rings (already-made) show up on their hands. And then when you hold down v on a player, an animation plays and is supposed to do damage to them. Then after that, an explosion will finish them off.
  2. What is the issue? Include screenshots / videos if possible!
    The issue is that when I try to make the rings go on their hands, it doesn’t work and the animation doesn’t play. Before I incorporated the rings, the animation played fine.
  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    I looked for solutions on the developer hub. I have tried to put the rings in different locations but it doesn’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!
