Module The Animation Script



local AnimationTable = {}

AnimationTable.Animations = {
	
	RightDribble = 04900889894,
	LeftDribble = 04900894178,
	FakeCross = 04900885146,
	
	



}

return AnimationTable

btw i also copied this from a youtube live stream

here’s the link

Where are you getting the error? " [Attempt To Index nil with WaitForChild]"

#3

you meant the line?

Well I can’t see the line through here so just tell me what the line says

#5

It’s not advised to do this, this is called polling and it’s not efficient, a better way to wait for the character, is like this

local player = game.Players.LocalPlayer
local character = player.Character or player.Characteradded:Wait()

#6

see the code with a print(Handle(“FakeCross”))

#7

You can’t print that because [handle] is a function and your not returning anything

#8

Is that in a LocalScript or a Script?

#9

local script

that does the animations

#10

well my animation does not play

#11

You told the script is erroring, right? Reading the above conversation, I couldn’t make it clear which line it is erroring. Could you specify it?

Edit: Nevermind, got it.Could you specify the line of the error attempt to index nil with WaitForChild()?

#12

This is erroring because, at this point, Ball does not exist. According to the if statment, if the ball does not exist, do the dribble stuff, if it does do then FakeCross. Your if statment are wrong.
Here is what’s correct:

local plr = game.Players.LocalPlayer
local character ) plr.Character

It seems that this script was just ripped out of the above video, please don’t do that, make your own scripts.

yes it is but i want the animation to play plus the ball exists in the workspace
