getElementData

[Drakath]

if getElementType(getElementData (source, "car")) == "vehicle" then 

WARNING: script\server.lua:47: Bad argument @ 'getElementType' [Expected element at argument 1]

car=getElementData(source, "car") 
destroyElement(car) 

WARNING: script\server.lua:141: Bad argument @ 'destroyElement' [Expected element at argument 1]

Why can't I use getElementData as an element? With what should I replace it in order for the script to output no errors or warnings?

You can, unless it is destroyed.

local car=getElementData(source, "car") 
if isElement(car) then -- check if it still does exist. 
    destroyElement(car) 
end

element data is a very bad way for such thing as vehicle elements. You should use tables for that. Otherwise a hacker could create a custom vehicle and set it as the element data. Or set any existing one to its element data and own it.

Thanks.

True, but for him it isn't important at the moment.

It's more important than you think it is. Scripting *badly-designed* codes might become a habit and one might use this all the time. It's very easy to get a bad habit and pretty much difficult to get rid of it. So studying should go on properly, without *easier* workarounds.

It is important, but not everybody wants to learn lua else he would ask for the tables.
