Unity 2017 Changelist

Tuesday, January 3, 2017

We do a thing in Rust's subreddit where we get people to post their ideal changelog.

I find these threads a lot more useful than reading people's dissertations on what they want changed. They're brief, skimmable, and they're not full of justifications, speculation and predictions.

So here's my changelist for Unity in 2017.

  • Removed deprecated component accessors on Component

  • Reduced standalone memory usage

  • Added ComponentRef (automatically fills with the sibling component)

  • Allowed resources folder to be over 2GB without using bundles

  • Editor Dark Skin is the only skin

  • Steam is treated as a platform (includes Steam SDK)

  • Cloudbuild can upload to Steam

  • Added GameObject.Spawn which spawns a prefab but doesn't call Awake/Start/OnEnable until you call go.Instantiate() (allows setting up before actual creation)

  • Added PrefabPool

  • Added ParticleSystem.AutomaticallyRecycle bool (deletes gameobject when particle finishes)

  • Layer renamed to RenderLayer

  • Added PhysicsLayer

  • RenderLayer/PhysicsLayers are a bitfield, objects can be in multiple layers

  • Up to 64 RenderLayer/PhysicsLayers

  • Tags are bitfields, objects can have multiple tags

  • Added Sound.Play( clip, position, volume, pitch, etc )

  • Built in components aren't sealed, are derivable, default editor still works

  • Up to 64 tags
