I want to create a pin ball game . Can anyone help please?

I am not so experienced with BP but I know how to create door rotation animation . but, I need to use a collision box to trigger a door movement. What if I want to create a class BP that opens the door on key press without collision box and only with key press.

SO with the doorrotation bp, the initiator node (the very first one that is red), I’m assuming you are starting it with and event begin on Collision node? Just replace that one with an input node. You can find this by right clicking the background and it should be under input>keyboard events>button
