trigger clientside event error

[hipolitalakaj]

Hi!

I trying to trigger a clientside event in server.lua which exists in client.lua but the debugscript says "Server triggered clientside event onClientReceiveItems, but event is not added clientside"

What's wrong? 

---- client ----

function receiveItems(data)
	item_table = {}
	item_table = data

	if(itemElement and getElementType(itemElement) == "player" and itemElement == localPlayer or itemElement==nil )then
		item_table_player = data
		for index, value in ipairs (item_table) do
			if value[5] > 0 then
				item_table_action[tonumber(value[5])] = {item_table[tonumber(index)][6], item_table[tonumber(index)][1], item_table[tonumber(index)][3]}
			end
		end
	end

	isMove = false
	movedItem = 0
	newCount = 0
	movedSlot = -1
	movedCount = 0
	movedValue = 0
	selectedAmount = 0
	currentActionSlot = 0
end
addEvent("onClientReceiveItems", true)
addEventHandler("onClientReceiveItems", getRootElement(), receiveItems)

---- server ----

function loadPlayerItems(element)
	local ownerID = tonumber(getElementData(element, "acc:id") or -1) 

	array[0][ownerID] = {}

	local item = -1
		
	for i = 1, 50 do
		array[0][ownerID][i] = {-1, -1, -1, -1, -1, -1, -1}
	end

	local loadItems = dbPoll(dbQuery(connection, "SELECT * FROM items WHERE owner = ? AND type = 0", ownerID), -1)
	if #loadItems > 0 then
		for i, row in ipairs(loadItems) do
			item = tonumber(row['itemid']) or -1
			value = row['value'] or -1
			count = tonumber(row['count']) or -1
			slot = tonumber(row['slot']) or -1
			type = tonumber(row['type']) or -1
			slot = tonumber(row['slot']) or -1
			id = tonumber(row['id']) or -1
			actionslot =  tonumber(row['actionslot']) or -1
			duty = tonumber(row['dutyitem']) or -1
			array[tonumber(getType(element)) or 0][ownerID][slot] = {tonumber(item), value, tonumber(count), tonumber(id), tonumber(actionslot), tonumber(slot), tonumber(duty)}
		end
	end

	triggerClientEvent(element, "onClientReceiveItems", element, array[tonumber(getType(element)) or 0][ownerID]) 
end
addEvent("playerLoadItemsToServer", true)
addEventHandler("playerLoadItemsToServer", root, loadPlayerItems)

See this topic:

That guy has the same issue.

 

You get this error because you send a trigger event, but the clients/players haven't loaded their scripts.
This can be either an timing issue or there is another error which causes the script to fail loading.

The event onClientResourceStart is a great way to detect when a player can receive triggerClientEvents

Um, thanks for your reply. So I need to put a timer? if yes, where I need to put that timer? I still don't get it

Use onClientResourceStart to trigger the event "playerLoadItemsToServer" or trigger another server event to mark that the client is ready to communicate with the server side.

Also, you'll need to remove any call for the function 'loadPlayerItems'  in events that should be causing that error (it may be the event "onResourceStart" for example).

What do you mean? Something like this?

---- client ----

function receiveItems(data)
	item_table = {}
	item_table = data

	if(itemElement and getElementType(itemElement) == "player" and itemElement == localPlayer or itemElement==nil )then
		item_table_player = data
		for index, value in ipairs (item_table) do
			if value[5] > 0 then
				item_table_action[tonumber(value[5])] = {item_table[tonumber(index)][6], item_table[tonumber(index)][1], item_table[tonumber(index)][3]}
			end
		end
	end

	isMove = false
	movedItem = 0
	newCount = 0
	movedSlot = -1
	movedCount = 0
	movedValue = 0
	selectedAmount = 0
	currentActionSlot = 0
end
addEventHandler("onClientResourceStart", getRootElement(), receiveItems)

Nope, actually in that code the table "data" isn't being passed to the function.

What I mean is, where are you calling the function 'loadPlayerItems'? You should first fix what is causing this error message. After that, follow this step I said above:
