You should add the blocks slightly before they make it into the world

Good point, JetLennit. The entry of the blocks into the world is something I need to work on.

The feel of the keys is wrong. You want the jump to occur when the key is pressed, not released, for a better feel.

Hi danpost, on my computer it does jump when you press they key down. Do you have a mac? They can do weird things with the key commands. That's why I put in the mouse command instead. Are other people having this problem?

I'm using the standard "if(Greenfoot.isKeyDown())" way to get the keyboard input. Do you have a recommendation about a way that might work better? As I said, I'm not noticing this problem when I'm playing it, but I'm not saying it's not happening.

Also, I'm aware of the problem that sometimes you bounce the wrong direction horizontally. It's noted in the comments. I'll fix that pretty soon.

x-direction movement should only happen when the player press the key, not always, and the jump speed is too fast. Try to make things smooth. Any way, very good documentation for new leaners! :-D

BTW, I love the way you make the scroll endless. Try to make switch of those platforms out of the bound of the world. You can use

use"super(int width, int height, int cellsize, boolean bounded);" In your world class's constructor

Thanks Upupzealot! Those are very good suggestions.

As far as the keys, I explained incorrectly. The problem with the feel is that you cannot jump when the 'left' or 'right' key is down. Removing the 'else' before checking if 'isKeyDown("up") should help the feel.

Got it. That goes with Upupzealot's suggestion. I'll put that in the next update.
A new version of this scenario was uploaded on Wed Feb 05 04:02:09 UTC 2014 Took the suggestions of Upupzealot and Danpost. Slower falling and jumping for smoother graphics, changed the keyboard commands so you only move when key is down, and fixed how platforms come on the screen.

Aha, much better. You can build up another scenrio for each step you updated. So those people(mostly new leaners maybe) who fellows your video could figure out how things became better and better.

Will you be sharing your code? (Or is the code available in the video lessons description? I'll go check.) :)
