Help and Feedback Scripting Support
#1

hello everyone, I’m trying to make a footstep sound script, and I’m getting this problem of (invalid argument #3 (string expected, got table) ). Any help on how to fix this.

Script:

local soundboard = {

Use the tostring function when you’re attempting to change a Material’s sound inside a table, as it’s attempting to find a string value but apparently ended up being a table instead:

local floodMat = tostring(humanoid.FloorMaterial)
print(floodMat)

You should probably also change your Enums as well

Also how much sounds do you need geez

The sounds are grouped in lists. By the looks of it, you are assigning the SoundId as a table. You can fix this by:

-- change this line
footstepsSound.SoundId = soundOfMat
-- to this
footstepsSound.SoundId = soundOfMat[math.random(1,#soundOfMat)]

Good luck!
