Project Notes
This project is another example of my "race" experiment: It moves two sprites in seemingly the same way with different results due to how Scratch processes update cycles within loops.
Credit again goes to johnm for pointing me to this.

Oh! I made one of these, only with more scripts being tested! (link to project)

Hmm... That means... Optomization! Yayy!!! Now only if there were more things you could do to optomize scratch that aren't expected...

No affence, but I don't get it!

It says that the repeat block is slower than the forever block and the forever block is slower than a colum of scripts.

Hmm... it seems that the forever repeat loop goes smoother as the forever motion loop goes in more of a choppy motion....

it probably does that because it takes a little while for it to loop back :)

I probably will ask this the wrong way but..just wondering can you elucidate more on how scratch processes update cycles..etc.. this shows the why and the result..

I think you'll find this interesting; I seem to have stumbled across right-click sensing in Scratch. (link to project).

nice, check out my project that experiments with the time it takes Scratch to compute huge calculations: (link to project)

Oh, thanks!.... so that's why my project was so choppy....

Click on the Scripts and it will change into a cat.

I never would have thought that 2 different scripts that do the same thing have different results

Very informative. I like the cats, which appear by clicking the sprites.

You're the first one to notice them :) thank you, goch.

I'm sure people trying to optimize their 3D wireframe models will try to use this...it's really interesting!

A way to optimize this and make it less choppy at the same time: split the one huge forever loop into 10, each containing the move and wait.

WHOA! Cool! I never would have thought of trying this! Seems repeat and repeated scripts are not the same thing!

Thats rather interesting....

So it looks like Scratch "saves up" move statements in a loop and executes them all at the end of the loop? I am sure if I were to put a Wait statement between the Move blocks it would be different, yes?

You're right. Scratch currently does one display cycle per loop iteration. Wait statements within a loop also trigger a display update. So the lesson to be learned from this is: You can warp computational stuff by putting several statements into a loop or into different threads. As this will supress display cycles this method may not be adequate for anything visual.

lol. great graphical way to demonstrate what is sorta a "race" condition.

I was doing a time test once and I noted that if something repeats 41 times it is 1 second 81 and it is 2 seconds. Just thought you might like to know that.

Cool! Instresting expiriment with the 'loop' blocks.
