Thx dude, this tutorial finally worked for me, after all the struggle I had to went through. The three main problems for me were, if can help some of you :
1. The use of dots instead of comas for the coordinates : 0.86 is wrong, you should go for 0,86. Well i guess it depends on your computer settings about decimal numbers;
2. The color and police settings : it took me some time before i realized the text was set up by default as black (0,0,0) and that the police size was also of 0. Btw, what does A stands for ?
3. When it all worked, i had to set up manually the path for the osu game files, as it was not installed at the same place at all.
However i stream casually but i noticed that for me, it looks quite fine (even though sometimes the text flashes in the middle of the screen),
but the watchers only see briefly and every 2 seconds at quick flash at the place the counters should be, and nothing at all the rest of the time. Any ideas ?
