for what ever it's worth I'd like to share the code below with you.
I got the code to do what I wanted. Object falls onto a rotating platform
and stays there without falling off.

from pygame.locals import *

Thanks all for the very informative responses especially to Alan for being
descriptive.
I am now going to make my movement linear and move away from my current
circular one.
I hope a little bit of fun and "Thank you" emails fall into the order of
the day..
:)

Hi Dilliup,
Please try to avoid using the phrase, "I don't understand how does
not get ...".
You might not realize it, but it's radioactive: it's has a v
Thanks Alan.

I do not understand how Alan does not get the code that is in this thread.
Anyway I can conclude by saying that a friend of mine who is not in this
thread solved the problem and I would like to share it with you. He has
changed only a very smal portion in the original code that i posted in this

That does not go by a mile of what I asked.
You've asked three different things:
1) Why the += form gives different results from the assignment form,
2) Why some code you apparently wriotre worked outside a class
but no
x=42 good
x += 42 -x ?

Alan, are you telling me that there is no way that one can arrive at X2
which is the NEXT place that X1 will be after "some increment"?
old x position = X1
new x position= X1 + some increment value
which can be written as :new X =

Not sure if this is what you're looking for, but I would also use cos for
the x coordinate as suggested. If:
self.rect.x = self.radius * math.cos(self.angle) + self.center_x
self.rect.y = self.radius * math.sin(self.angle) + self.center_y
Take a derivative (assume: angle +=
Thank you Alan. Understood. I already knew that. My question is
How to to do it the second way.
some code = what?
My question is, how does one arrive at the code to put in place of "some
code"? The code I used does not work correctly.
The code is in this chain of email.
I hope I am clear in what I

The point is you cannot do it.
The second approach always uses the current value of x.
The first approach may or may not use the cur

Above 1 works. 2 does not. Why is that?
Because they do completely different th
Thanks all for the responses.
Charles Cossé - yes I can write a simple pygame program that makes a
sprite move in a circle but it may not be the style and order that many may
approve or accept. I consider myself a student. :)
No one has pointed out why the object moves in a circle properly in the
