All geometry and some other assets should be loaded async-ly.
|
||
|
|
|
||
|
|
We need a background thread which loads assets from disk. It will have a queue, where any script can register it's file for loading.
|
||
|
|
|
||
|
|
We need a way to wait until specific asset is loaded.
|

|

First identify what is taking time using Profiler. Maybe not all time goes on loading from disk. Some of it may be spent on converting the mesh.
|
||
|
|
|
||
|
|
Identified what is taking time:
|
||
|
|
|
||
|
|
- loading from disk (mostly takes around 20 ms, and goes up to 70 ms, but for some txds it goes to 100 ms)
|
||
|
|
|
||
|
|
- creating mesh (mostly around 10 ms, but can go up to 100 ms)
|
||
|
|
|
||
|
|
- attach collision model (mostly below the time to create mesh, but in some cases it goes to more than 100 ms)
|
||
|
|
|
||
|
|
- updating divisions - runs almost every frame (especially when loading something), even though you invoke it with 100 ms interval - takes around 30 ms
|
||
|

## TODO
|
||
|
|
|
||
|
|
- order in which Async functions will return is not equal to order of call to those functions - because some of loading objects may be cached - adjust Geometry.LoadAsync() when loading multiple textures
|
||
|
|
|
||
|
|
- create meshes asyncly (this means converting mesh and it's textures)
|
||
|
|
|
||
|
|
- attach collision model asyncly
|
||
|
|
|
||
|
|
- update divisions in separate thread ? or optimize division system ?
|
||
|
|
|
||
|
|
- unload map objects which are not visible to any focus point for given amount of time - this means destroying meshes, materials, textures, and removing references to loaded data in RAM
|
||
|
|
|
||
|
|
|

|
|
## TIPS
|
||
|
|
|
||
|
|
- attaching collision model takes a lot of memory - why ? - because it reads archive file
|
||
|
|
|
||
|
|
- dedicated server doesn't need textures - we can detect if we are running as dedicated server, and skip loading textures
