about the syntax from createBlipAttachedTo

[IIYAMA]

blip createBlipAttachedTo ( element elementToAttachTo, [int icon=0, int size=2, int r=255, int g=0, int b=0,  
int a=255, int ordering=0, float visibleDistance=99999.0, visibleTo = getRootElement()] ) 

The last argument is about the visibility from the blip, I can fill in 1 element or the root. Is it possible to fill in more elements(players)?

support tables?

[NodZen]

i think so, but i not sure. And tables? Why not?

[IIYAMA]

Because nobody says anything about tables?

The only way to know is to try it.

[IIYAMA]

or to wait for somebody who knows already the answer, it does not have my priority that's why I post it on the forum.

I am 100% sure somebody already tried it.

You can make wrappers of blip functions, here's an example of how would createBlipAttachedTo seem like:

_createBlipAttachedTo = createBlipAttachedTo 
function createBlipAttachedTo ( ... ) 
    if ( type ( arg [ #arg ] ) ~= 'table' ) then 
        return _createBlipAttachedTo ( ... ) 
    end 
    local pElement = createElement ( "blip" ) 
    local blipArray = {} 
     
    for i,v in ipairs ( arg [ #arg ] ) do 
        local newArg = arg 
        newArg [ #newArg ] = nil 
         
        blipArray [ #blipArray + 1 ] = createBlipAttachedTo ( unpack ( newArg ), v ) 
    end 
     
    setElementData ( pElement, "blips", blipArray ) 
    return pElement 
end 

The con is that you have to modify other functions that has a blip element as parameter.

Some of the arguments I don't understand.

Like:

... 
arg -- doesn't this have to be defined?(probably it is already defined with ... but I don't understand that) 
  

Right now I am making for every player a blip and create 1 element that contains all elements?

Isn't it better to use setElementVisibleTo to reduce the amount of elements?

arg is a Lua pre-defined variable, it has the same meaning of '...' which is a table of variables.

Indeed, I didn't think about the most efficient way to do it, I firstly had that idea and this code is supposed to give you an idea of how you could do it.

Thank you for explaining me things I did not used before and how to make a wrapper.

I think I will use setElementVisibleTo to manage the visibility.

You are welcome.
