Collision, Jumping and other little problems

Hello there!

I have several problems with the game im currently creating.

  1. I have a jump function. How can i forbid “jumping in the air”, so that i only have one jump in a specific time?

  2. I’m also not sure about Collisions. Is the “Panda” Collision connected with the Map? If I create a map with blender, do i have to do anything else other than converting it to .egg?

Thank you for your answers
