Decode Sprites

carrion · 17 January 2024, 11:35

In my game Robot Jet Action 2 I load most of the data in one file and decompose it in the mem. Except sprites. I load sprites separately as seams there's no DecodeSprites function.
Is there away to Decode sprites from memory?

I mean I could load shapes and convert them to sprites but I'm afraid that it will take double amount of the mem, does it?

You could use "GetaSprite Sprite#, Shape#" to create a sprite out of the shape.
After creating the shape you can free the shapes memory by using "Free Shape Shape#".

But you are right: while creating the sprite you will need the extra memory before you can free it up.

Yeah, plus I'm afraid that creating sprites this way would end up with memory fragmented a lot.

I wonder why there's no decodeSprites function , wha was the rationale?

There are goood chances the fragmentation will be not that as severe if you convert one shape after another to a sprite.

The memory needed for GetaSprite could could be allocated at the same memory location then.

I possibly could implment a DecodeSprites-function but the benefit would be low as your requirement is fullfilled with the existing routines.

You are right

What I will do I will try to use CludgeBitmap on already allocated mem and load sprite bitmap there.
Thanks for ideas.
