Delphi: Detect start and end of window move

I'm using the OnIdle-event for some simple animations, and it works all right. The trouble, though, is when the user starts to move or resize the window, the OnIdle-event stops firing until the move/resize-operation is completed. I need to detect when this happens, so that I can pause all animations. But how do I detect movement of the...

Changing the speed of a circular motion

I'm looking for a way to smoothly increase or decrease the speed of a circular movement. Using the parametric equation of a circle, I can move an object in a circle over time: x = center_x + radius * sin(time * speed) y = center_y + radius * cos(time * speed) The problem with this approach is that I can't simply do speed = speed + 1 ...

Comment my MMO client<>server movement handling.

I'm working on a basic 2D flash MMO. The first alpha will contain the basics: players can move around. This is, I think, also the most important part to be highly optimized. As movement happens all the time and costs a lot of bandwidth. This is how my current system works: All movement is calculated by the client When a client changes...

Optimizing transition/movement smoothness for a 2D flash game.

Update 6: Fenomenas suggested me to re-create everything as simple as possible. I had my doubts that this would make any difference as the algorithm remains the same, and performance did not seem to be the issue. Anyway, it was the only suggestion I got so here it is: 30 FPS: http://www.feedpostal.com/test/simple/30/SimpleMovement.htm...
