Available Events¶

DefaultExecutionOrder Attribute¶

In our WASM implementation, the [DefaultExecutionOrder] attribute only affects ordering inside the VM, not Unity's native script order. It guarantees ordering only among WasmBehaviours, including when multiple behaviours receive the same event.

Example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

[DefaultExecutionOrder(-100)]
public partial class EarlyBird : WasmBehaviour {
    void Awake() {
        // This script will run before most others.
    }

    private void OnPlayerJoined(Player player) {
        // This will fire before scripts with lower execution order.
    }
}

 3
 4
 5
 6
 7
 8
 9
10

[DefaultExecutionOrder(10)]
public partial class GoofyNameHere : WasmBehaviour {
    void Awake() {
        // This script will run after most others.
    }

    private void OnPlayerJoined(Player player) {
        // This will always fire after EarlyBird's OnPlayerJoined.
    }
}

Unity Events¶

Special Execution Order Events¶

These events run after all corresponding Unity calls, including scripts outside your VM. For example, sampling a player's position is most accurate in the PostLateUpdate event, as local Avatar IK and Network IK will have been applied by then.

Gotcha, Scene Execution Order¶

Unity processes script execution order on a per-scene basis. When multiple scenes are loaded additively, the configured execution order is applied in full for each scene individually, not across all scenes at once.
See Unity Documentation for reference.

This means that even with PostFixedUpdate, PostUpdate, and PostLateUpdate, you need to consider which scene your scripts belong to and what they are trying to run after. For the vast majority of use cases, this behaviour will not be something you need to necessarily think about, but do keep it in mind.

For example:

• World Scene (active)

  • Runs FixedUpdate
  • Runs Update
  • Runs LateUpdate

• Remote Avatars/Props/Portals Scene (additive)

  • Runs FixedUpdate
  • Runs Update
  • Runs LateUpdate

• Local Avatar & LateEventManager (DontDestroyOnLoad)

  • Runs FixedUpdate
  • Fires PostFixedUpdate for all in order of subscription.
  • Runs Update
  • Fires PostUpdate for all in order of subscription.
  • Runs LateUpdate
  • Fires PostLateUpdate for all in order of subscription.

World evaluates -> Remote Avatars/Props evaluate -> Local Avatar & Late Events evaluate.
