I'm trying to figure out how to use the Action Gameplay to change the gameplay. Somehow it's not working for me. Take for a simple example, the default simple platformer game which BB2 serve as a tutorial. I want to add a simple Action: keep all the game settings, just change the direction of gravity, and the jump power, I expect to see the character to stick to the roof and jump button will have the player dash downward. But instead the character just can't move properly. Can't jump. Can't move around. Anyone have the same problem?
