Loading and unloading of resources

[shaz68]

I am instantiating animated objects from prefabs, then using Resources.Load() to change the animation.

If I do this in a loop and create 10 objects, is the resource actually loaded 10 times, or just once, and all objects use the same animation?

Do I have to do anything to unload the resource when the scene changes, or will all of the objects being destroyed trigger garbage collection on the animation?

As far as I am aware, the resource is only loaded once. You can verify that by keeping track of memory.

From what I have noticed, when the scene changes, everything gets unloaded, so you won't need to manually keep track of things if you don't need to.

In our titles where we have had to do this, we had to keep track of everything, as we were using it as a customization system. It wasn't really that complicated - we had a singleton class where we requested an animation.

thanks for that.  I'm still getting familiar with Unity - need to figure out tracking memory usage.

If you have Unity Pro, the profiler is really really useful.

I don't have it yet, but I will down the track.
