Hello everyone!
I’ve have created a function that creates a button for me:
```
public void createBox(float left, float top, float width, float height, string content) {
GUI.Box(new Rect((screenX-screenX)+left, (screenY-screenY)+top, width, height), content);
}
```
Just to be more easier to create buttons, but when i try to make an if with this button he shows me a implicit conversion types, that’s obviously. I call my method inside of other script in a void OnGUI() {}
Well, i just wanna know if i can do this in otherwise, create a method which will create a button for me, and later i put an if and it’ll works fine :D.
Thanks.

You need to return a boolean value for it to work with a `GUI.Button`,
```
public bool createButtonx(float left, float top, float width, float height, string content) {
return GUI.Button(...);
}
```
