Hi! how would you draw some points on screen and then get their coordinates in desired Co-sys ? The output should be just pair of X Y newline , for each drawn point.
I wanna do some test for some new classes and don't wanna rewrite possible exisitng program

Take a look at my "osgg" game, the buildin level editor does exactly this, and leaves you with a list of coordinates that it will happily write to a file for you. You might want to change a few lines of code to make it print out coordinates to screen while editing and to make it output in the desired format (it's raw text and there is a tiny bit of metadata that you could strip out).

Funny side note, I actually used the level editor to create the ship, base and enemy graphics in the game, so it was a bit chicken and egg, osgg was the main tool used to create osgg :P

Yeah thanks very much , but your answer comes with much aftertime :P,
I wanted to test the culling mechanism with quadtrees, already wrote a simple generator and python script to display point sets :P.
