When Loading BTAsset, GC Alloc a lot

[Yuewah ChanParticipant]

mind.behaviorTreeAsset = Resources.Load(string.Format(“BehaviorTrees/{0}”,”Guest”), typeof(BTAsset)) as BTAsset;
aiRig.AI.AIInit();

The BT contains some Custom Action which need to load using Assembly.CreateInstance. In Unity Deep Profiler, it allocate a lot of memory, is it possible to minimize it ?

I don’t believe those numbers are accurate. For example, they are reporting String.Split taking 172KB. I don’t think that performing a split operation on a 30 character string requires almost 200k of memory. The similarly, calling type.Name doesn’t require 283K. I doubt it uses 283 bytes. In addition, the assembly sizes are skewed because you are running in the editor.

In general, the profiler serves as a guide for finding problems, but can be wildly inaccurate at times.

[Yuewah ChanParticipant]

sorry, profile in editor is inaccurate, let me try to profile in device instead.

In Rain 1.x , when I load BT ( ~ 50 nodes, half of them is custom class in global assembly ) in runtime, it didn’t drop too much frame-rate, but after upgraded to Rain 2.x, it drop significantly, could you have any performance test case for this situation ?

[Yuewah ChanParticipant]

I found that BTLoader is very slow when the BT contains many custom class in global assembly as it use reflection to create the class object. Any thing that I can do to make it load faster ?

I’ll put a note in our task list to look into optimizing that. We can probably cache assemblies and check most recently used assemblies first.

[Yuewah ChanParticipant]

Is your method used in RAIN 1.x for custom action ? I have no problem on it.

[Yuewah ChanParticipant]

What is the time frame to optimize for caching the assemblies? If it is too long, we need to rollback to rain 1.x

Send an email to jester please. We can discuss possibly getting you a pre-release custom version in advance of our planned release schedule.

[Yuewah ChanParticipant]

email is sent.

[Yuewah ChanParticipant]

I know you guys is busy, but how is the pre-release custom version ?

[primeKeymaster]

Working on it. Give me a ping on Monday.
