No problem for the help and good job. I don't know why this happens but the movement is very slow, this doesn't happen when I download the scenario, so my only guess is that it could be some kind of performance issue. One last thing is that there is a bug when you jump and land on a platform you sometimes jump through that platform and land in the middle of it.

I'm fixing all the bugs now, making a menu, and making the first level to go with it. Wish me luck; it's gon' be a lon' night.

Thanks, I'm currently working on the UI and collision detection, and you can always click menu up top to go back and respawn, but I will add respawning soon!

I think I've found it. But I won't tell here. Can I ask you, if you here? http://www.greenfoot.org/scenarios/5719 It's a messaging scenario. You first have to play it, so that you are registered there. If you want to do, then tell me here please.

Once you start my scenario while logged in, you will be registered. Also, I looked and both of you ARE registered. The left and right arrows near the top of the screen allows scrolling through all the registered users.

I've recently created a physics scenario that simulates gravity using a bouncing ball. I made collision detection for it that is 100% incapable of glitching into things (to my knowledge). You should take a look! http://www.greenfoot.org/scenarios/9172 Also, here is the code (to save you some trouble)!

Greenfoot.isKeyDown("s")){sdown=false;} if (shadowImagery==true)getWorld().addObject(new Shadow(getImage()),getX(),getY()); //Zero Gravity Cheat if (Greenfoot.isKeyDown("g")&&gdown==false){ if (gravity==true){gravity=false;}else{gravity=true;} gdown=true; }else if (!
