Re: need help in getting image coordinates
Maybe those simple collision functions will work for you:
GRRLIB_PtInRect
GRRLIB_RectInRect
GRRLIB_RectOnRect

Re: need help in getting image coordinates
thank you for your reply but,i dont think that these functions can help me.I need to find the exaclty x,y coordinates of my image which is randomly created with the function rand().and also there is no command like target.x or target_x (target is the texture)

Re: need help in getting image coordinates
If you generate the coordinates why don't you keep them in memory

If you need information about the GRRLIB_texImg structure: http://grrlib.santo.fr/doc/struct_g_r_r … x_img.html

Re: need help in getting image coordinates
Look at the code in the basic_drawing example folder. Check the code where Link is moving over a rupee.

Re: need help in getting image coordinates
my code is based on this example but it uses rectonrect function this one"(GRRLIB_RectOnRect(320+left, 240+top, 48, 64, 618, 434, 12, 30))"

Re: need help in getting image coordinates
It's so easy to do something like this:
static int CoordX = 0;
static int CoordY = 0;
...
CoordX = 22; // Random value
CoordY = 44; // Random value
GRRLIB_DrawImg(CoordX, CoordY, MyTexture, 0, 1, 1, 0xFFFFFFFF);
...
GRRLIB_RectOnRect using CoordX and CoordY...
