[Newbies] Re: Randomness + Pause/Delay?

Yeah, I was surprised (shocked?) it didn't work in Etoys. Oh, well...

That just freezes the world during the path following. Which I would consider a bug - in the Etoys image, path following happens simultaneously with all other animations.
Adding such a delay would be trivial, just have a textual script with something like "(Delay forSeconds: 1) wait". But that would not be a substitute for a real "wait" tile. It does not just stop the script it is in, but *every* script in the whole system.

Delay can be accomplished with "follow path."

1) Put an ellipse morph at 100 at 100
2) Give it a path from present location straight up to top of screen.
3) Create script named "delay" for ellipse
       Ellipse do menu item follow existing path
       Ellipse x <- 100
       Ellipse y <- 100
4) Put a rectangle morph at bottom center of screen
5) Create script for rectangle
       Ellipse delay
       Rectangle forward by 5

Click on ! to execute rectangle script. Ellipse follows path and returns to 100 at 100, delaying move of rectangle.

Well, often in Etoys you need a slight shift in perspective to make the solution fit a lot better. Approaches from other systems do not always map well.
E.g., a typical approach to implement PacMan would be to have PacMan object with a script to eat peas. In Etoys it's a lot easier for each pea to have a script checking if it was eaten.
So if you could let us know, in high-level terms, what the intended behavior is, we might be able to come up with ideas how to do that in
 Etoys.

Thanks.

One forgets it's not a real-time simulation.

 are there any plans for one?

I saw these two posts last year. They might help:
