Custom item causes server disconnection when used

[D4rkh0bb1T]

Hi everyone,

The title says it all. When playing as a server, my custom item causes a disconnection when I use it. Someone can help?

There is no crash log as the game is not likely crashing...

If you are playing a local game without caves, the only thing you can do in this case is to place print("sample") all over your code to track the exact steps that lead up to the disconnection.

Else, I assume the server is silently crashing. Check the server's log!

No crashing, the server just disconnect. This is a edible item.

I use a local inst = GetPlayer(), Telling me that inst has a nil value. It works well when I play in single player.

It's like the server is not sending the right information to the client so it disconnect,,, something like that.

The GetPlayer thing was to be able to use inst.component.talker, haven't found another way to do it. Plus, other ''inst'' would'nt be working. Now things being to get confused.

if its when its in the inventory u can use local player = inst.components.inventoryitem.owner to get the player holding it

GetPlayer() has no meaning in DST, because there can be multiple players, as opposed to single player in DS.

IIRC, if it's in the backpack worn by a player, this returns the backpack, not the player.

local player = inst.components.inventoryitem:GetGrandOwner() should return the player.

backpack

Well, nothing should return in the backpack!

That's a edible item and I wanted the character to say something when eaten. In single player, the code works very well, but not when playing with someone. I have three item based on the same frame, and they don't work in MP. The other items I have are coded in a different way and seems to work, I can't figure out what I should change, remove, place.  I'll show you what it looks like, :

local function reduce3()
	local inst = GetPlayer()
	
	if breakcounter > 1 then
		breakcounter = breakcounter - 1
	else
		intens = 0
		inst.Light:SetIntensity(intens)
		inst.Light:Enable(false)
		print "Light off"
		breakcounter = breakcounter - 1
	end
	
	inst.components.talker:Say("Light has gone...", 4)
	
end


local function oneaten(inst, eater)
    local inst = GetPlayer()
	addlight()
	
	inst.components.talker:Say("Let there be light!", 4)
end

function addlight()
	local inst = GetPlayer()
	
	if inst.Light then
	else 
		inst.entity:AddLight()
		print "new light :("
	end
	intens = 0.75
	
	--
	breakcounter = breakcounter + 1
	print (breakcounter)
    --
	
	inst.Light:Enable(true)
    inst.Light:SetIntensity(intens) -- 0.75
    inst.Light:SetColour(197/255,197/255,50/255)
    inst.Light:SetFalloff( 1.0 ) -- 0.5
    inst.Light:SetRadius( 4 ) -- 2

	inst:DoTaskInTime(potiontime-3, reduce1)
	inst:DoTaskInTime(potiontime-2, reduce2)
	inst:DoTaskInTime(potiontime-1, reduce3)
end

 

The crash log :

EDIT : I just tried to host a game without Caves and it works.

Then I started a new game with Caves and I got disconnected.

What's going wrong with Caves? What's wrong with the code? Something is missing isn it?

When you enable caves, the game is no longer directly on the server, but rather you create a local server and connect using a seperate client. It's like a miniature model of actual server-client communication.

GetPlayer() does not work in DST. Instead, pass along the player variable like this:

1. in oneaten, it's already available as "eater"

2. pass it to addlight like this:

addlight(eater)

3. and then change the head of "addlight" function to:

local function addlight(inst)

4. remove the "inst=GetPlayer()" line

Repeat the last two steps for the reduce functions. (the player variable is already being given to the functions by DoTaskInTime, but they need to receive it properly)

[Aquaterion]

ye change

inst.components.talker:Say("Let there be light!", 4)

to

eater.components.talker:Say("Let there be light!", 4)

[D4rkh0bb1T]

All right! I managed to fix that item among other that was not right.

Replacing inst by eater at some places and adding variables the the functions.

I went through a lot of crashes but I finally did it! Yeah!

Thanx to you guys for helping me out! That character will be very fun to play with
