What you have created is images of bubbles on the flat surfaces of the cube. (1) the cube is not semi-transparent. (2) the bubble are not 'inside' the cube (rotating around each other) This, therefore, does not satisfy my stated requirements.

I am not sure what is going on. I had bettered the score of 1356 on level 103 at least four times and the high score for that level does not change. Oh, and yes, I was signed on each time. The scores were 1338, 1296, 1294, and 1300.

I am using a cosine function to regulate the pendulum. Multiplied by the maximum angle give the current angle of the pendulum. The length of the wire is an inverse factor of the incremental change in the function. I do not know how this translates in terms of its period.

Can you make a translucent cube with bubbles set inside of it (that rotate with the cube). You accomplish that, I will 'like' it. You may have run out of number keys, but there are also plenty of letter keys!

The way you programmed the 'wasd' keys, they are prioritized: up, down, left, then right. It would be nice if combinations (one of 'ws' with one of 'ad') would work on rotating the image at the same time. Also the 'f' key should act like a toggle, but it does not always change to mode (you should use 'Greenfoot.getKey' to catch the 'f' key instead of Greenfoot.isKeyDown).

It is better to use a 'Discussion' thread for help, as you do not have the formating tags here. See my new Discussion thread "Help on 'Chess by Razzo'".

@MatheMagician, you may indeed. The scenario is open source, so just download it. While running, if you see an image you like, just press "i" or "I" and the image will automatically save within the scenario folder. I also have an uploaded 'Kaleidoscope' scenario which is a take-off of this one. Have fun.
