Sorry if I'm being too rookie on this, but could somebody explain me one thing that happens in the sprite demo?
When the sprites collide, the borders become red. I don't understand were is that effect coming from...
Thanx!

Dont worry, I can explain you. If you look the SpriteCollision.cpp code, you can see this line:
isCollision=sprRabbit->Collision(surfCursor,&rCursor,-1,-1,1);and in documentation you can find this about Collision member:
Citarint CRM32Pro_CSprite::Collision (CRM32Pro_CSprite * spr,
Sint16 spr_x = -1,
Sint16 spr_y = -1,
Sint16 this_x = -1,
Sint16 this_y = -1,
Uint8 debug = 0
)
Check collision with another sprite.
Parameters:
spr test sprite collision against this sprite
spr_x by default is -1 and it uses current screen X position of the sprite 'spr'. Other value, means only your absolute X position on your own system coordinates
spr_y by default is -1 and it uses current screen Y position of the sprite 'spr'. Other value, means only your absolute Y position on your own system coordinates
this_x by default is -1 and it uses current screen X position of this sprite. Other value, means only your absolute X position on your own system coordinates
this_y by default is -1 and it uses current screen Y position of this sprite. Other value, means only your absolute Y position on your own system coordinates
debug by default is 0 and it won´t to render any debug information. Otherwise, it will show bounding box and so on
So the blue box is debug information to see the real limits of the sprite and the red box is the bounding box or what it is the same, the area where pixel perfect collision will be performed.
Let me know if you have any other problem :)
cheers!
