Having trouble with animations, how do I make the animations work inside of my tool?

Hello! I'm still a beginner to LUA, and i'm wondering how an animation for a weapon, such as a sword works. Do I insert them into the tool itself, the handle, or do I need a script to run them? Please help!

You need to use a script. You load the animation into the player's character's humanoid, and it will play the animation from there. Make sure that the animation priority is set to the highest one (action) so that it wont be interrupted by anything else. Here's a wiki page to help you do this; if you need any more assistance in regards to the formatting or actually making the animation then I'll be glad to help :)

you can us the dance potion as base, just create your animation, and configure in the potion tool
