hey i want my character to add a jumping animation to my doodlejump clone style.
I think I know how to specify the sprites but I fail with the query isJumping = true. can someone help me?
the coin provides the platform on which the player lands
the ground is only at the start

I need help. i have to pose for a school project. then it occurred to me to take some in the style of the cozmo robot but i have no idea how to do it best. Can someone help me or give me tips on how to best get it programmed ... when you start the app you should just open up as if he was sleeping and then just blink etc ..
