Question about bitmap.dispose

[hima]

  When we create a sprite like this

  @object = Sprite.new
  @object.bitmap = Bitmap.new(some_width,some_height)

when dispose, should I just do this

  @object.dispose

or this

  @object.bitmap.dispose
  @object.dispose

I mean, would the bitmap be freed if the sprite's freed? In the animation system that I use, if I don't free the bitmap, it'll keep on eating up the memory. But in the shooting game that I'm working on, I don't have to free the bitmap and the memory is still the same, so it confuses me

Thanks you in advance ^ ^

Dispose them both

That's what I thought too. But I still want to know as for the reason why. And when I do that in my shooting game, all the bullets bitmap are gone, not the only one that is out of screen. But when I use only self.dispose, only the sprite is gone and the memory is still the same. = =

Both are different objects, and each of them must be disposed separatedly, as in the Sprite implementation it does not dispose the bitmaps it´s holding. If it was that way, RPG::Cache would never be possible :D Also, Sprites consumes way much less memory than bitmaps. That´s why you see that the memory consume of the game doesn´t drop much after you dispose it. Think of it as a single bitmap object is reutilized in several sprites, and therefore saving memory by not needing a single bitmap for each sprite to show the same thing on the screen

I say, if you load a bitmap through the cache, don´t dispose it unless you have a good reason lol, and try not to load lots of bitmaps at once too, it´ll run your computer out of memory if you abuse :D

Thanks Linkin_T!  I get it now. After reading your post and go back to the manual, I realize it's also written in the manual about Rpg::Cahce.  Should have read it more carefully  orz
