see this video: the challenge it´s how the player can jumping over obstacles isometrics in any direction. I believe it´s imposible in buildbox, i made a test in construct 2, it´s easy when you created the events.
whoosh!! jumping over any direction is pretty hard. I'm facing the same problem. However, i set up with Action Button which make the character face the desire direction. Then press jump. Basically, you have to press two button to jump in the desire direction. This is not the best solution.
can you share us, a little bbdoc when you come back at home please and please. Only little example, for I can see your logic please. You can send me PM if you want. Anyway, I will try your tips, but if you have time, show me.
