Problem with custom inventory system

Help and Feedback Scripting Support
#1

So I have this script:

player.Character.Humanoid:EquipTool(player.Backpack["slot"..key.ThingOccupying.Value])

“key” is the number that the player pressed, and ThingOccupying is a string value that contains the name of the tool occupying that slot. The images that represent the slots are named slot1,slot2,slot3, etc.
However, this line gives me an error:

 Players.nicknickphoenix.PlayerGui.ScreenGui.LocalScript:43: attempt to index nil with 'Value'

How should I fix it so that it will equip the tool that is supposed to be equipped?

The error suggests that ThingOccupying is nil .

Also, you shouldn’t equip tools on the client due to replication issues. Try using a RemoteEvent to tell the server to equip the tool.

So, “key” is the number that the player pressed. What exactly is it? Is it a NumberValue or Enum.KeyCode or something else?

We need to know this, since the only thing the error message is saying is that "there is no ‘ThingsOccupying’ inside of ‘key’

I used

local mouse = player:GetMouse()
	 
mouse.KeyDown:connect(function(key)

to get the key

Oh yeah, forgot about that however ThingOccupying shouldn’t be nilScreen Shot 2021-08-07 at 12.41.01 PM
(As you can see, it’s a string value inside all the slots)

In this case, “key” is either something like MouseButton1 or an enum thing idk, but it does not contain ThingsOccupying for sure.

when I do

print("slot"..key)

In the output, I get “slot1”, which is the name of the image button and slot1.ThingOccupying.Value should be the name of the tool, but instead it says “attempt to index nil with ‘Value’”

Oh I think I got it. It’s a simple logic error. This should maybe work:

player.Character.Humanoid:EquipTool(player.Backpack[("slot"..key).ThingOccupying.Value])

Replace your script’s line that caused the error with this.

Thanks, however it still did not work

#11

Did you get any errors? If yes please tell me what the error was.

#12

I just got the same error again

#13

Send me a screenshot of the player’s backpact in Explorer please.

Actually I managed to fix it, I changed the line to

player.Character.Humanoid:EquipTool(player.Backpack[player.PlayerGui.ScreenGui["slot"..key].ThingOccupying.Value])
