In "Square Stacker" template, I didn't understand the scoring mechanism. First the rewards points object is pretty useless there and It's OK to delete it. I understand it's about "drop block" object taking damage that spawns something big in taking damage animation, which will touch the character upon taking damage, and that increases score. It's probably that "gray" action. I tried clearing taking damage animation, and adding the gray action again. But there is no way to add an action there! Can anyone please explain it to me?
You have to use copy/paste to get the action in there. This is not something that was originally intended but it works and we do not plan to remove it. Instead in the future, we will make adding actions there easier.
