Thanks for 1° question : it work. To use these 2 graphs was a good idea to martyrize crazy modders
Concerning 2° question : the pb is that I have erased the content of all counter sprites files in the game, by security to test. Logically, if these are used to create the circles, these circles should no more be displayed.
But they stay in place (blue for blue side, and red for red side (the 2 sides of my mod).
In reason of the used colors for the circles, I suspected that the program create (in hard code) automatically these circles, basing his action on the color of sprites each side, and I tested to give the 2 sides the same blue color for all sprites (3D and nato). But it changed nothing, blue side keep blue circles and red side keep red circle.
And I did not found no any file in bitmaps and Interface directory that could intervene to create these mysterious circles. Seems it's hard coded because only HQ have these blue and red circles circles, not other units (and this last fact is logical because I hare erased the content of all unit coubnter sprites files in the game (for all powers, and in game + in user campaign)
EDIT : pb is Solved => It was the
unit_counter_flag_sprites that created these circles, I forgottet it in my searching.
Hubert placed little piece of graphs everywhere to martyrize the poor modders.
All works perfect now, thanks
) : my work was just to adapt with some tips
