Dimension Check

[ThePCGuy]

Well i got a function that makes a object at the position of a player, but when changing dimension the object disappears ofcourse. But is there a way to make a automatic system that checks if the player changes from dimension the object does too?

There's no native event, but you can build your own.

Event:

onClientPreRender

Function:

getElementDimension 

You store the current dimension on a variable, then you check, if it changed, you trigger an event with:

triggerEvent

Isnt the server going to lag if it sets the object to the players dimension every frame?

There's 2 ways, 1 is a timer and the other is a render.

If you create a render all you have to do is check if the object is in the same dimension as the player and if it's not then set it's dimension to the player's.

Example 1: Server-sided

setTimer(function() 
    for _,player in ipairs(getElementsByType("player"))do 
        for _,child in ipairs(getElementChildren(player))do 
            if getElementType(child) == "object" then 
                local playerDim = getElementDimension(player) 
                if getElementDimension(child) ~= playerDim then 
                    setElementDimension(child,playerDim) 
                end 
            end 
        end 
    end 
end,3000,0) 

Example 2: Client-side

addEventHandler("onClientPreRender",root,function() 
    for _,player in ipairs(getElementsByType("player"))do 
        for _,child in ipairs(getElementChildren(player))do 
            if getElementType(child) == "object" then 
                local playerDim = getElementDimension(player) 
                if getElementDimension(child) ~= playerDim then 
                    setElementDimension(child,playerDim) 
                end 
            end 
        end 
    end 
end)

Another dirty solution is using onElementDataChange

When you setElementDimension, you set at the same time an element data to the player.

That could work no?

[Castillo]

If the server uses a lot of element data, then it would be a problem.

[Jaysds1]

Ya, where as if you set the object as the player's child then it would still sync but not as bad as using element data.

Follow what Solidsnake suggested, you have a variable that stores your dimension the previous frame and then you compare your new dimension onClientPreRender with the variable you had stored, only then has your dimension changed and you can trigger your own event.

It will only trigger once then per dimension change and server wont lag at all. You can even change the object dimension client sided if you wish, then its fully client sided.
