Where do I use the place-image option to place the myself, shark, food1,
food2 images at required positions? Do I give that in the initial-world?
The define-struct has to be exactly as you showed right? Or do I have to
give the positions by using the make-posn there?
I am a total amateur to Racke
When he said world, he meant a piece of data that describes the state of the
program, for example a data structure that stores the positions of “myself” and
“shark1”, etc in a structure:
(define-struct world (myself-posn food1-posn food2-posn shark1-posn))
And when you use big-bang and on-tick-e

aims to supplant Skype in all areas: text, voice, and video. Blight is in

Hi Zee,
What's the shape of the world?
Racket Users list:

How can I make 2 different images move in different ways inside only 1
world.
I placed "myself" at (posn 550 550) = right end of the screen
Placed "food" at respective fixed position.
I want "shark1" to move only in x-direction automatically on clock-tick.
I want to control "myself" via key-pre

Thanks for the insights!
I'm glad that Racket users can afford the luxury of understanding these
things /in principle/ while using included batteries in the real world. :)

I'd expect this more difficult to design than to program.
My first idea would be to base everything on sin
