[Solved] How to check if character has something equipped on head?

[. . .]

@Serpens Can I ask you one last question? If you don't wanna help then that's fine i'll just give up on this .

So, I tried doing something like

AddPlayerPostInit(function(inst)

inst:ListenForEvent("equip", function(inst, data)
local item = data.item
   if item.prefab == "earmuffshat" and not inst.HasTag("perfect") then
   inst.components.talker:Say("my ears are safe.")
   inst.soundproof = true
   elseif not item.prefab == "earmuffshat" then
   return
   end
end)

end)

and I get this crash, what did I do wrong?

Spoiler

Also, what's the event for unequipping a item ?

"unequip"

try to find out the error yourself This time the log error does not show the exact error in your script. But you know that something might be nil.
"index something" mostly mean, that you try to make eg. "data.item" while data is nil. Or item.prefab, while prefab is nil.
So you could check, if one of them is nil. The easiest way to test it, is to put print statements in your code like print("data: "..tostring(data))
Then you can hit CTRL+L ingame to see the logs and see what data and all the other stuff is.

But if data or item would be nil, the error log would not include entityscript. So now you go into scripts/entityscript.lua and go to line 492. There you see it is the function "HasTag" that throws the error. So you have to check, if something about "HasTag" is wrong in your code.
Most likely you will notice, that item/inst is not nil, so it should work.
What else could be wrong with "inst.HasTag("perfect")" ? It is a typo

@Serpens Serpens, thanks so much for your guidance ! I figured out what the error was...   "inst.HasTag("perfect")" this was a typo thanks for the hint, looks like it's not good to code when you're sleepy, haha!

So, I did something like this

AddPlayerPostInit(function(inst, data)

inst:ListenForEvent("equip", function(inst, data)
local item = data.item
   if item.prefab == "earmuffshat" and not inst:HasTag("perfect") then
   inst.components.talker:Say("safensnsasz.")
   inst.soundproof = true
   elseif not item.prefab == "earmuffshat" then
   return
   end
end)

inst:ListenForEvent("unequip", function(inst, data)
local item = data.item
   if item.prefab == "earmuffshat" and not inst:HasTag("perfect") then
   inst.components.talker:Say("No more protection foir me.")
   inst.soundproof = nil
   elseif not item.prefab == "earmuffshat" then
   return
   end
end)

end)

and put a check for inst.soundproof on my code & it works just like I intended ! I have no idea why the equip code didn't work though? But whatever this code works just as fine  & I couldn't have done it without you Serpens, really thanks so much!
