"integers" for every player?

[kevin433]

Hi,

I recently began to script in LUA, and I have experience with PAWN. The problem is now that i want an "integer" which every player has his own off. I just know how to do this in SA:MP, but not in MTA. I mean something like this (I hope some guys understand what i want to do), I just can show how i would write it in SA:MP:

new lightson[MAX_PLAYERS];
 
if(lightson[playerid] == 1)
{
...... etc
}

How should i write this in LUA? I've checked the wiki, but I couldn't find it there.

If you want to associate information with players, the official way to do that is setElementData and getElementData.

What is meaned with "string key"? I just saw the example on the Wiki page and there the key was "tempdata.originalnick". I just need to save an integer

the key is simply something to find the information later. for example you use setElementData(somePlayer,"phoneNumber",666999333) and later you use getElementData(somePlayer,"phoneNumber") to get the information you have previously set, in this case 666999333

if this way seems uncomfortable to you you can also use a table

local playerPhoneNumberTable = {}
playerPhoneNumberTable[somePlayerElement] = 666999333
playerPhoneNumberTable[someOtherPlayerElement] = 123123123

Should this work?

setElementData(source,"lightson", 1)

Don't I have to make a local or global "lightson"? Or should it just be like that? And can I do things like this?

if(getElementData(source, "lightson") == 1) then
outputChatBox("Your lights are on!", source)
end

yep, that should work, you dont need a global, you're just adding a key and a value to it.

yes that would work. and in this case you could even save some memory by using true and false instead of an integer

setElementData(source,"lightson", true)

if(getElementData(source, "lightson") == true) then
outputChatBox("Your lights are on!", source)
end

That wouldn't save any memory, but it's a good idea anyway.
