Button onClick method return error

So basically i have a button that calls a method on it’s “On Click”, the issue comes with that method returning a GameObject because i also call that method from other parts of the code rather than only the button, so i came with:

ArgumentException: method return type is incompatible

Do i have to copy the SAME method without return JUST for the button? is there any way to avoid the issue? thanks!

It’s probably better to define a separate method for the button. Perhaps one just calling the other one, and dealing with the returned object.

Yep! just came to that idea too, simple method with no return for the method that calls the other method, worked 10/10
