How cool is the texture management?

Hi @all.

When an app loads the very same texture more than once does Gideros handle this case gracefully? Meaning does Gideros notice that the texture is already loaded? Or does Gideros actually load it again? (Do I have to take care more accurate of the asset management by myself?)

As far as I am aware, all files, textures, sounds and music are loaded once and cached.

Yes as Scouser said, you can call them multiple times, but if they are already in memory, they will be reused

Thanks for the information .

And what about actively unload textures? Is it necessary or does Gideros handle this part as well? Based on some heuristics like memory workload or the rendering frequency of each texture?

Do you mean deleting texture from memory?
If yes, then it's done by Lua garbage collection, which uses mark and sweep algorithm, which periodically checks all memory allocations, and if there are no references to them, marks them and then frees the memory.
That is why texture is not immediately removed from the memory, when reference is deleted, but stays until next mark and sweep cycle.

Ok, so it probably has some kind of this implemented http://giderosmobile.com/forum/discussion/comment/21402#Comment_21402 respectively the c counterpart.
