Why does Callable.From(staticMethod) fail in C#?

Callable.From expects an instance method bound to a target object. Static methods have no instance. Wrap in lambda: Callable.From(() => MyClass.StaticMethod()).

Capture in lambda body. Callable.From(() => MyClass.StaticMethod(arg)). Lambda holds the args via closure.

Lambda allocates a small object per Callable. For frequent invocation, cache the Callable in a field; reuse across calls.

Fix: Godot Callable.From Static Method Fails

Quick answer: Wrap in lambda: Callable.From(() => MyStatic()). Cache the Callable for reuse.

Pass a static method to ToSignal callback. Compile error. Callable expects instance binding.

The Fix

// Wrap static in lambda
var callable = Callable.From(() => MyClass.DoSomething(42));

// Use as deferred
callable.CallDeferred();

// Connect to signal
node.Connect(SomeNode.SignalName.SomeSignal, callable);

Lambda captures the static call. Callable wraps the lambda. Engine invokes when needed.

Verifying

Static method runs via Callable. Compile clean.

“Lambda wrap. Callable works.”
