Assets Loading / Memory Management in C++ and Lua.

[Hgawmphdmph]

Hi all,

I'm in the process of converting key parts of my partially written framework using Leadwerks from Lua into C++ and I have a question about loaded assets and memory management.

Looking at things like the CreateNew load parameter, the Asset path attribute and the Copy function, I'm guessing that if I load the same asset more than once, the API will just return a pointer to the existing instance already loaded, in order to save memory - is that correct?

If so, my real question is, what happens if I load a Texture from C++ and then load the same one again from my Lua code. Will the API return a Lua table pointing to the original asset?

Alternatively, is there some way of accessing a C++ loaded asset or entity from Lua or Lua table of an asset or entity from C++? Last time I tried this I got an access violation.

Cheers and thanks in advance,
Colin

Yes.

It doesn't matter if the load command is called from C++ or Lua. The engine uses the same routine to check for the loaded asset by file path.

Hi Josh,

That's brilliant, thanks so much for such a quick reply.
(Absolutely love Leadwerks by the way. Best engine I've ever used.)

Cheers,
Colin
