Add a callback to a button's onClick event. Note this at this point does only supports callback with no arguments.

Note: SaintsEditor has a more powerful OnButtonClick. If you have SaintsEditor enabled, it's recommended to use OnButtonClick instead.

• string funcName the callback function name

• string buttonComp=null the button component name.

  If null, it'll try to get the button component by this order:

  1. the field itself
  2. get the Button component from the field itself
  3. get the Button component from the current target

  If it's not null, the search order will be:

  1. get the field of this name from current target
  2. call a function of this name from current target

using SaintsField;

[GetComponent, ButtonAddOnClick(nameof(OnClick))] public Button button;

private void OnClick()
{
    Debug.Log("Button clicked!");
}
