How does it know what and when to pack & load? Packing everything in your project is also bad - often there are textures and models that are not supposed to get into the game and are not actually used, i.e. Loading everything on start up is silly as the user device will quickly run out of memory.
Your assets are ready, your code is working, your levels are polished! Time to build the final game and release it to the world! But how is that actually working? Will Unity just ship all assets in the project and load them on start up? Who is this for: game developers enthusiasts with some basic knowledge of assets project organization. If you wanna know more about how asset references work in Unity, read our previous article: Unity References Basics. Indirectly referenced stuff remains in memory until all references are released.Ĭomparing asset references using = or Equals WILL NOT WORK if:įirst asset is referenced in a scene and the second one is in a bundle.įirst asset is referenced in one bundle while the second one is in another bundle.įirst asset is referenced by one scene and the second one is referenced in another scene.įirst asset is referenced in a bundle and the second one is referenced in the same bundle. Unity bundles AND SCENES have 4 GB (2 GB for older versions) size limitation. All subsequent level files will just refer to the first one and load it on demand.Īn asset packed by scenes AND bundles is actually duplicated. While Unity packs scenes during build, when a shared asset is met it will be packed in the first level in the build list that is met. There are 4 ways assets are packed and loaded: Scenes, Resources, Bundles, StreamingAssets
As a follow-up to our last Unity References Basics post, Snapshot Games’ Filip Slavov shares some more behind-the-scenes tips for aspiring developers coding in Unity, and explains how in our game, Phoenix Point, a bug around the Technician’s mech arms animation happened! TL DR
