Hello @ltucker , I looked at your code, but I guess I’m not seeing the problem. The dog goes up with the up key. I didn’t see any code to make it go down. It seems to be working as expected unless I’m reading your expectations incorrectly. ---

Her code to make it go down is at lines 56-7 The code at lines 50-51 should cause the dog to go up with a vel of 2 but it will only do it while the up key is being held down. I have the exact same code (with a different player name) in the one I did on my own and it goes up with a vel of 2 as soon as I hit the up key… I’m not sure what’s going on - I don’t think it’s her code, I think it’s her gamelab (?) ---

@ltucker, Line 45 is the line that is causing the issue you are seeing. The dog’s y value starts at 300 and with each click of the up key, it gets even smaller. As a result, line 45 is always in play and unless you are clicking on the up key, the velocityY of the dog is set to 0. Hope this helps! Mike ---

Thanks - I just found it before I logged into my email - wish I’d have read this first!
