TStateTreeStrongExecutionContext | Unreal Engine 5.7 Documentation

API > API/Plugins > API/Plugins/StateTreeModule

Execution context to interact with the state tree instance data asynchronously. It should only be allocated on the stack. You are responsible for making it thread-safe if needed. ThreadSafeAsyncCallback.AddLambda( MyTag, WeakContext = Context.MakeWeakExecutionContext() { TStateTreeStrongExecutionContext StrongContext = WeakContext.CreateStrongContext(); if (StrongContext.SendEvent()) { ... } });
