Best Practices aren't static -- as Unity's underlying architecture evolves to support Data-Oriented Design, the old tricks might no longer be the best ways to squeeze performance out of the engine. In this talk, we'll discuss how Unity has changed between Unity 5, Unity 2017 and Unity 2018 and how to take advantage of these changes.
Among other topics, we'll focus on:
* Unity's multithreading system.
* Changes to Transforms.
* Animations & Animators.
Speaker:
Ian Dundore - Unity Technologies
2:19 - string.Equals()
11:41 - Disabling NullCheck for individual method(s)
13:16 - Transforms and scene hierarchies
23:38 - Disabling Physics.SyncTransforms
25:54 - Audio
32:48 - Preferring legacy Animation over Animator/Mecanim
37:50 - Animator Layers
39:12 - Preferring Generic rig over Humanoid rig
41:23 - Pooling Animators using keepControllerStateOnDisable
OMFG, I love this guy. I could listen to him for hours.
One of the best 46 minutes from any of the Unites. I *love* this one.
Great speech!
You should add message boxes with that tables in Unity when add some component to gameobject
The whole Animator / Animation component thing must be sorted out once and for all. Depreciated? Not depreciated? Legacy? Simple? Just rename the old one to LightweightAnimator and be done with it. Seriously :P
I wonder that too! I don't know if it's still the case (it was two years ago) but if trying to animate materials with the legacy animation, it wouldn't work. A lot of people reported it to Unity and Unity's answer was that legacy animation was to be deprecated and that they won't fix it.
Animating materials is one specific case of where animations are usually simple and it's really easy to give a lot of life to a world by doing so. A real shame we can't use legacy animation for that...
He literally says in the talk that they do not plan to depreciate it.
ZoidbergForPresident he says that but he's not alone at unity. they don't fix the bugs and continue acting like use it but don't, it doesn't make any sense !
It may mean it's not supported anymore but not deprecated ?
But I agree with you in that it should be a clear consensus.
Ian mention other presentation about performance - Real-world performance optimization - Kerry Turner. Will be that presentation published?
The problem is How can I simplified the hierarchy?
Can we get the slides?
Also, can we get the slides?
OK, I'm going to sound dumb but what exactly is IL2CPP? Seen it in some talks but I've never gotten an explanation of what it is and it seems important enough...
It's their system for changing platform independent C# code and compiling into platform-specific C++ code. It generally should provide some amount of performance gain, but has a few limitations. Currently iOS requires it, but it's available on most other major platforms.
Oh, just that then. But do devs have to go into that code at any time?
this is rather old but I'm answering it anyway :P normally you dont have to. ideally its just change the setting, get better performance.
That is quite complex I don't understand most of this ^^, But thanks !
Does this mean its best if we dont make transform hierarchies at all ? think "transforms have no child transforms at all" ?
Is assigning parent during instantiation i.e Instantiate(prefab, parent) recommended in 2018.1?? Because unparented transforms are giving great performance.
Is Ian still at Unity?
What? No suit this year?
how the heck this videos got so little views.
Why would you do massive amounts of string comparisons in a performance-sensitive context to begin with?
Like he says at the start, it depends on your use cases. If somebody happens to be using Unity to create something (not just a game) that does a large number of string comparisons, then that would be a potential performance improvement. His point is to apply the same process he's using to optimize, not the specific optimizations themselves.
OK, I do batch my positions and do all the “set transform position" in my renderPositionSystem at the end, Still not good, the perfomance for 5,000 + gameobject is unacceptable, I have switched to the job systems.
THIS Program is useful today to seeing! I am so handsome! (subscribes do you like unity videos?)
