Is there a way to invert the "On object clicked" event?

This is an example. Lets say when clicked I want the sprite to be on frame 1, but when not clicked I want the sprite to be on frame 2. How would I do that?

"On click" is a trigger, it can't be inverted. You can use two conditions:

Mouse Cursor over object + Mouse left button is down -> Set frame 1

Else -> Set frame 2

my method
