How can I sign up for an action <float> method without a variable?

How can I sign up for an action method without a variable. I know how to sign a method with a variable, but this option does not suit me.

For example:

public static event Action<float> action_1;

Somewhere in another class:

private void Init(){
AnotherClass.Action_1 += Mehod_1;
AnotherClass.Action_1 += Mehod_2;}

And methods:

private void Mehod_1(float value){}

private void Mehod_2(){}

How can I connect the second method to action?

You can’t. It takes a float. You’ll need to add another action that doesn’t take a float.

Wrap it with an anonymous delegate that takes a float as a forwarding method:

AnotherClass.Action_1 += (f) => Method_2();

Note that if you expect to unregister it, you’ll have to keep a ref to that delegate around:

_someClassLevelFieldToStoreDelRef = (f) => Method_2();
AnotherClass.Action_1 += _someClassLevelFieldToStoreDelRef;

//... later
AnotherClass.Action_1 += _someClassLevelFieldToStoreDelRef;

Though honestly, at this point… why not just make it a class level method rather than a delegate.
