Showing checkpoints only for THAT player

[kuwalda]

Hello.

I have a bit problem with my script:

  
function testejam(thePlayer, command) 
        if ( getElementData ( thePlayer, "dbid" ) == 2 ) then 
            setElementData(thePlayer, "time", getTickCount ()) 
        end 
    local pid = getElementData ( thePlayer, "dbid" ) 
    local ciga = getElementData ( thePlayer, "dbid" ) 
    destroyElement(markeritis) 
    markeritis = createMarker ( blueBerryRally[ciga][1], blueBerryRally[ciga][2], blueBerryRally[ciga][3], "checkpoint", 6, 190, 156, 252, 170 ) 
    if ( #blueBerryRally == ciga ) then 
        outputChatBox("You finished, nice", thePlayer, 255, 255, 0) 
        outputChatBox("Your time:"..(getTickCount () - getElementData( thePlayer, "time" )) / 1000 .."sec.", root, 255, 255, 0) 
        setElementData(thePlayer, "dbid", 1) 
    end  
    setElementData ( thePlayer, "dbid", getElementData ( thePlayer, "dbid" ) + 1 ) 
    addEventHandler( "onMarkerHit", markeritis, testejam ) 
end 
addCommandHandler("race", testejam) 
  

But I still have some problems I haven`t figured out how to fix them:

* when player types /race ,why does everyone sees checkpoints and are allowed to drive through them? I have tried using setElementVisibleTo function but it works only partly.? How to make those checkpoints availabe only for that person, who asked for /race ?

* when player finishes race, his time is stored in table, for later use. Lets say i have 3 guys who have raced:

x with time 21sec

y with time 15sec

z with time 17sec

How to determen witch one of those was fastest? How to write it in code?

* Is it possible to make this script work for multiple people? For that I mean if someone is driving this track and someone else types /race, he gets his own checkpoints and wont disturb other players?

And one more question offtopic - how can I make variable, with variable.

Like:

x = 6

theplayernamex ,so it would be like theplayername6

Here's the edited code for the visibility of the marker:

function testejam(thePlayer, command) 
        if ( getElementData ( thePlayer, "dbid" ) == 2 ) then 
            setElementData(thePlayer, "time", getTickCount ()) 
        end 
    local pid = getElementData ( thePlayer, "dbid" ) 
    local ciga = getElementData ( thePlayer, "dbid" ) 
    destroyElement(markeritis) 
    markeritis = createMarker ( blueBerryRally[ciga][1], blueBerryRally[ciga][2], blueBerryRally[ciga][3], "checkpoint", 6, 190, 156, 252, 170, thePlayer ) 
    setElementVisibleTo(markeritis, root, false) 
    setElementVisibleTo(markeritis, thePlayer, true) 
   if ( #blueBerryRally == ciga ) then 
        outputChatBox("You finished, nice", thePlayer, 255, 255, 0) 
        outputChatBox("Your time:"..(getTickCount () - getElementData( thePlayer, "time" )) / 1000 .."sec.", root, 255, 255, 0) 
        setElementData(thePlayer, "dbid", 1) 
    end  
    setElementData ( thePlayer, "dbid", getElementData ( thePlayer, "dbid" ) + 1 ) 
    addEventHandler( "onMarkerHit", markeritis, testejam ) 
end 
addCommandHandler("race", testejam) 

As for the timing and finding out who finished first:

--t is the table that holds all the finish times of the players. 
--It should be in this layout for the function to work: t[thePlayer] = finishtime 
function findRaceWinner(t) 
    if t and type(t) == 'table' then 
        local time, winner = math.huge 
        for thePlayer, theTime in pairs(t) do 
            if theTime < time then 
                winner, time = thePlayer, theTime 
            end 
        end 
        return winner, time 
    end 
    return false 
end 

-Yes it is very possible to make it work for multiple people. Each player should get his own marker now with the visibility fixed, you will probably run into a few issues though.

-To make a dynamic variable name, you can utilize a table.

--name refers to the player name. 
-- 
local x = 6 
table[name..x] = value 
  

Another way would be to use _G, which is a table of all global variables ( of this resource, I think ). But that will create a GLOBAL dynamic variable, not a local one.

local x = 6 
_G[name..x] = value 
  

Note: I didn't mess with the rest of your script, didn't remove redundancies like pid, etc; You should remove it since you don't need it.
