CreateSprite

[_aNdy_]

I'm coding my first full game (after a couple of false starts) after having already coded a few applications. I'm creating a sprite with:

Code: Select all

Global sp_LEVELMAZE = CreateSprite(#PB_Any, #TILEW * #MAZEW, #TILEH * #MAZEH)

If the code repeats and then this command is encountered again, does 'CreateSprite' delete the old version and create a new one, or is the 'old' sprite floating in memory somewhere needing to be 'freed'?

By using #PB_Any the function returns a handle. It's up to you to delete the sprite, because next time another handle is returned and the current one still stays valid (though your variable now points to the new handle).
It's differently, when not using #PB_Any: If the handle with a fixed number is already in use, it is freed and recreated with the new parameters by the function.

In this instance, because you are using #PB_Any, the old one will still be around but you'll no longer have a 'handle' to it because you've overwritten the value of sp_LEVELMAZE.

You can use IsSprite and FreeSprite to be tidier:

Code: Select all

Global sp_LEVELMAZE 
If IsSprite(sp_LEVELMAZE)
  FreeSprite(sp_LEVELMAZE)
EndIf
sp_LEVELMAZE = CreateSprite(#PB_Any, #TILEW * #MAZEW, #TILEH * #MAZEH)

Thanks for the quick responses! All understood and code inserted!
