When i pull out my weapon my characters does weird things,
my character gets faster, moves diagonally, sometimes stops moving, all of this happends
when i pull out my weapon and only move backwards, the weapon being pulled out is just
a script cloning a sword in to the characters hand
heres an example of what happends
all Im doing in this clip is holding S [which moves my character back]
This could be the weapon itself, try setting the contents of the tool to massless.
It’s the humanoids man, you never trust a humanoid. Also probably due to some funky collisions, humanoids can do some really funky things.
so how would i go about fixing this?
it seemed to have slowed down the character, but he is still doing weird things
You have to search for a direct cause of the problem, there are many different possible causes from constrains to scripts to body movers and of course humanoids.
Alright thanks for the reply 
Have you used free models? That could be the problem because sometimes there are malicious scripts in them…
I have not used free models…
Hmm… Is the tool CanCollide set to false?
Yes the tools CanColide is set to false
Try replacing the tool with something else, and tell me if there is the same problem.
I have tried replacing the parts of the tool but the problem still persists
It could’ve be the animation itself. I suggest you keep that animation, but add a script that checks if the character is walking or not. If yes, then walking animation + sword animation, else the idle animation + sword animation.
I hope i didn’t mess up.
I have tried that but it didnt work
What do you animate with?
CFrame or Animation Editor.
Animation Editor is what i use
Do you block the walking animation, when pulling out a sword?
No i do not block the walking animation, when pulling out a sword
Maybe the animation doesn’t only affect the arm. It might affect the other body parts too.
