[Sync] and [Command] Attributes

Aside from configuring your CoherenceSync bindings from within the Configure window, it's possible to use the [Sync] and [Command] C# attributes directly on your scripts. Your Prefabs will get updated to require such bindings.

Sync Attribute

Mark public fields and properties to be synchronized over the network.

[Sync]
public int health;

It's possible to migrate the variable automatically, if you decide to change its definition:

[Sync("health")]
public float hp;

If a variable is never updated after it is first initialized, it can be flagged to only be synchronized when the GameObject is created. This will improve performance, as coherence won't need to continually sample its value for changes like it would normally do.

[Sync(DefaultSyncMode = SyncMode.CreationOnly)]
public Color teamColor;

Command Attribute

Mark public methods to be invoked over the network. Method return type must be void.

[Command]
public void Heal(int amount)
{
    ...
}

It's possible to migrate the command automatically, if you decide to change the method signature:

[Command("Heal", typeof(int))]
public void IncreaseHp(float hp)
{
    ...
}

Note that marking a command attribute only marks it as programmatically usable. It does not mean it will be automatically called over the network when executed.

You still need to follow the guidelines in the Messaging with Commands article to make it work.
