Hi,
If you are starting with PlayMaker, you should grab a coffee ( or two
) and watch the various screencasts and videos on PlayMaker, then these concepts will start to make sense and you'll be able to apply them then in your particular cases.
In your case:
1: Create a new event "MY BUTTON CLICK" and assign this event in your GUIButton action
2: Right click on the State and select "Add Transition", and navigate to that "MY BUTTON CLICK",
3: transit from this event to a new state, do something here, and come back to the original state using a "FINISH EVENT" or another custom event depending on what you want to do there.
2: don't use MOUSE OVER, it's advanced and generally not a good practice, prefer MOUSE ENTER and MOUSE EXIT and maintain a boolean flag "over", then you can check this bool value to know if the mouse is over or not,
Bye,
Jean
