How to check if a function is null?

I tried to use this code to disable a light that appears when an in game key is pressed.

if (OnMouseDown == null) { key.light.enabled = false; }

Instead I received an Operator==' cannot be applied to operands of type method group' and null'

Is there an easier way to do this, or to fix my code?

Thank you.

1 answer:

Functions can't be null. Put the code in OnMouseUp instead. Although talking about pressing keys doesn't make a lot of sense when using OnMouseDown/Up so I don't know if that's what you actually want.

Thanks! And it's for a piano key, which is why I talked about keys.
