How to get values from a table/array ([1] = value)

#1

Hello! I got an issue with tables.

local materials = {
	[Enum.Material.WoodPlanks] = 9058073414,
	[Enum.Material.Wood] = 9058073414,
	[Enum.Material.Plastic] = 74510715852116,
	[Enum.Material.SmoothPlastic] = 74510715852116
}

I want to find the material the player is standing on (Humanoid.FloorMaterial) inside of the table and then take the sound id of it to play a sound.

I searched the internet however all I found is people asking about simple thing as these;

local t = {"cats"}

Which is not what im looking for

Thanks in advance!

NOTE: When giving me code please explain what things do because I have seen people just give code without any extra comments and call it a day.

I believe every enum has a .Value property, which is a unique number assigned to it. Something like this:

local materials = {
	[Enum.Material.WoodPlanks.Value] = 9058073414,
	[Enum.Material.Wood.Value] = 9058073414,
	[Enum.Material.Plastic.Value] = 74510715852116,
	[Enum.Material.SmoothPlastic.Value] = 74510715852116
}

All this may not be necessary though, because enums are hashable, you can use them as keys in a table.

materials[Humanoid.FloorMaterial]

What does that do? Could you please provide more information?

#5

if you assign a variable to that you get the sound id for the material

local soundID = materials[Humanoid.FloorMaterial]

Hmm how do I do this…

Tried table.unpack and printed, returned nil.

Tried for loops, nothing…

#7

What are you asking? If you’re asking how to determine which id to use, use the expression @Hzodx mentioned earlier:

local soundID = materials[Humanoid.FloorMaterial]
#8

I think that it printed nil when I tried it

#9

Wait I think that know whats wrong

#10

Output is still printing out nil…

#11

Do you maybe have another method for this?

#12

Can you send the code? The full code.

I made many attempts on this one

local materials = {
	[Enum.Material.WoodPlanks] = 9058073414,
	[Enum.Material.Wood] = 9058073414,
	[Enum.Material.Plastic] = 74510715852116,
	[Enum.Material.SmoothPlastic] = 74510715852116
}
script.Parent.SpeedController.FootstepEvent.OnServerEvent:Connect(function()
	print("serverfootstep")
	--local un = table.unpack(materials, script.Parent.Humanoid.FloorMaterial.Value, script.Parent.Humanoid.FloorMaterial.Value)
	--print(un)
	--for material, id in pairs(materials) do
	--	if material == script.Parent.Humanoid.FloorMaterial.Value then
	--		print(material, id)
	--	end
	--end
	--table.find(materials, script.Parent.Humanoid.FloorMaterial.Value, 1)
	local soundid = materials[script.Parent.Humanoid.FloorMaterial]
	print(soundid)
	--fs.SoundId = table.find(materials, script.Parent.Humanoid.FloorMaterial, 1)
	--type(materials)
	--print(table.find(materials, script.Parent.Humanoid.FloorMaterial, 1))
end)

for loop worked only once, then mysteriously stopped working

#15

This exact thing worked for me, it must be something else, are you getting any errors?

#16

No errors in the output

(annoying character limit)

So thats why… hmm

#18

I know the issue, I just had to put a tiny delay before firing the event on client side. Credits to @Hzodx for providing the solution to the first and main issue!
