How to use these commands? Give me some examples, please.

1.DrawCircle
INFO: Draw a 3d circle at a with size s and color c
2.DrawLine
INFO: Draw a 3d line from a to b with color c
3.DrawLinePop
INFO: Draw a 3d line from a to b with color c with a circle at the end of the target lin
4.GetHighlightBackgroundColor
INFO: color GetHighlightBackgroundColor()
5.GetHighlightForegroundColor
INFO: color GetHighlightForegroundColor()

Nope sorry, those commands are secret

Code: Select all

DrawCircle( Position, Radius, Color )
DrawCircle( VECTOR3( {100, 50, 200} ), 5, 'ff00ff00' )


Example:

Code: Select all

function DrawBaseRanger()
    -- Render the radius of any base and expansion location
    if Scenario.MasterChain._MASTERCHAIN_.BaseRanger then
        for Index, ArmyRanger in Scenario.MasterChain._MASTERCHAIN_.BaseRanger do
            for nodename, markerInfo in ArmyRanger do
                -- Draw the inner circle black
                DrawCircle(markerInfo.Pos, markerInfo.Rad-0.5, 'ff000000')
                -- Draw the main circle white
                DrawCircle(markerInfo.Pos, markerInfo.Rad, 'ffFFE0E0')
            end
        end
    end
end


Code: Select all

DrawLinePop( Position1, Position2, Color )
DrawLinePop( VECTOR3( {100, 50, 200} ), VECTOR3( {150, 50, 250} ), 'ff00ff00' )


I don't know the other 2 commands. But i guess the name tells us what they will do

Thanks! Do you know how to deal with the error?

The function needs a number and you're feeding it with a table.

You don't need to write the Vector stuff, its only for explanation that we need 3 values for the position:

Code: Select all

DrawLine( {2684.5, 63.96, 489.5} , {2682.5, 63.96, 514.5} , 'ff00ff00' )

Btw. when you don't know how to use something, you can try to search our game repo on the github, it usually have same examples https://github.com/FAForever/fa

@Uveso

OK! I got it
