[RESOLVED] a few general questions.
Just have a few simple questions.
1. In the draw image command what does the 4th condition specify? In this example it's 0, and in lesson 1 it's also 0.
GRRLIB_DrawImg(10, 50, tex_test_jpg, 0, 1, 1, GRRLIB_WHITE);
2. In the printf command, what's the 5th condition for?
GRRLIB_Printf(5, 100, tex_BMfont4, GRRLIB_WHITE, 1, "TO QUIT PRESS THE HOME BUTTON.");
3. In the draw rectangle command, what's the last condition? GRRLIB_Rectangle(left + 150, top + 150, 200, 200, 0x0000FFC8, 1) the comments seem to say it's alpha. Is there a reason to have it alpha, or perhaps put in 2 and have it be beta (if that's even what putting in 2 would do)?
4. Is there a draw circle command?
Answers to the following questions would be appreciated. Currently I'm just recreating an old pong game from basic, but i thought it would be nice to better know the commands for when I make a more complex game.

Re: [RESOLVED] a few general questions.
I think all your questions could be answered by looking at the HTML documentation: http://code.google.com/p/grrlib/downloads/list
Open the file named index.html and use the search engine at the top.
Useful links: libOGC Documentation, libOGC Repository, GRRLIB Documentation, GRRLIB Repository, #GRRLIB on IRC

Re: [RESOLVED] a few general questions.
1. angle of rotation (around the handlex and handley of the GRRLIB_texImg struct)
you can set it with GRRLIB_SetHandle (GRRLIB_texImg *tex, const int x, const int y)
2. it's the zoom factor (i dont recommend using it because it's bitmap, using freetypeGX is the prefered)
3. 1-filled,0-not filled ; you can use 'true' and 'false' as well. (alpha is the least significant 2-bytes of the color)
4. GRRLIB_Circle (const f32 x, const f32 y, const f32 radius, const u32 color, const u8 filled);
have fun creating!

Re: [RESOLVED] a few general questions.
Wow, that helped a lot, thanks! I didn't even know there was documentation, so that should be really useful.
