Error : attempt to compare number with boolean.

[v36u]

I know what a boolean is. True or false. But i don't understand how the variable "Radio Device", which changes, because it's a dayz server and that thing is an item and it is a *number*, was converted ( somehow ? ) to a boolean.

Here is that specific part of the code.

addCommandHandler("radiochat", function(player, _, ...)
	if (getElementData(player, "Radio Device") >= 1) then
		for _,v in ipairs(getElementsByType("player")) do
			if (getElementData(v, "Radio Device") >= 1) then
				if (getElementData(v, "radiochannel") == getElementData(player, "radiochannel")) then
					outputChatBox("#BCC643[Radio] "..getPlayerName(player):gsub("#%x%x%x%x%x%x", "").." : #d0e1e1"..table.concat({...}, " "):gsub("#%x%x%x%x%x%x", ""), v, 255, 255, 255, true);
				end
			end
		end
	else
		return
	end
end);

The thing is that i don't get the error on the first if which compares almost the same way the variable "Radio Device", but on the second if. And i don't know what is the problem. I bet it is something stupid and i don't see it.. ;/

Thanks in advance ^^

This will solve it in most cases:

1. If it is nil or false use OR to change it to the next value, which is in this case 0.

getElementData(player, "Radio Device") or 0

2. If it was a string before, it is now converted to a number, with the lua function tonumber. "100" (string) is now converted to 100 (number)

tonumber(getElementData(player, "Radio Device") or 0)

3. Apply your statement.

if tonumber(getElementData(player, "Radio Device") or 0) >= 1 then

 

 

 

addCommandHandler("radiochat", function(player, _, ...)
	if tonumber(getElementData(player, "Radio Device") or 0) >= 1 then
		for _,v in ipairs(getElementsByType("player")) do
			if tonumber(getElementData(v, "Radio Device") or 0) >= 1 then
				if getElementData(v, "radiochannel") == getElementData(player, "radiochannel") then
					outputChatBox("#BCC643[Radio] "..getPlayerName(player):gsub("#%x%x%x%x%x%x", "").." : #d0e1e1"..table.concat({...}, " "):gsub("#%x%x%x%x%x%x", ""), v, 255, 255, 255, true);
				end
			end
		end
	end
end)
