Spinning Roulette Wheel
-
there are 37 numbers on a roulette wheel (without number zero the casino could be in trouble pretty soon); and you probably also want some intermediate positions, especially when the wheel slows down, so 37*5 images seems more like it. :)

Not entirely on-topic, but... I can't stand games that waste time doing crap like that. Just randomize the number already! I'll always remember that the Amstrad that my father bought (mid-80s) had a Wheel Of Fortune game installed, but the clock was much slower than the developers had intended -- waiting for the wheel to stop spinning was horrible. What I recommend is randomizing a number and displaying just that number. Do it a few (10?) times so the user sees the numbers flashing. That's what I do for a dice game I wrote; it's much quicker and easier.

Maybee. I do see where your comming from, but the idea is to design a realistic and working mini roulette game, so the spinning wheel is a real big part of it. Also, this is just a fun app, and a doubt many other people will use it. The main idea for this is a learning curve for a beginner, and not so much the spinning wheel, but the fact that I can learn how to spin the wheel realisticaly, which may be usefull for other stuff. but thank you for your point of view!

Yes, WPF makes things like that considerably easier. No concern though. First thing to do is rotate the image, which is presumably represented as a bitmap in code. Get to the graphics object, and that's got two methods TranslateTransform and RotateTransform (as I recall) which should do the rotation. If everything's perfectly circular you may not need the translate transform. Then, create a method which rotates the image as needed. I'd probably create a custom control for just this purpose. You'll have to use the System.Windows.Forms timer to update the angle in such a way to make it look like real movement.

I am excited to get started with WPF, however, I think I should get through my "Head First C#" Book first, and learn C# properly. I will look into what you have sugested, and see if I can get something going. Thank you for the sugestion, Regards, Stephen

Hi, I was just woundering if anyone knows how I would do this... I have an image of a roulette wheel, and I would like to animate it as it was spinning, faster to slower and then stop. How would I achive this using c# and winforms, as I am not ready to delve into WPF just yet? Thank you, Kind Regards, Steve
You should just bite the bullet and learn WPF. Doing this in, well, GDI/GDI+ is the correct term here since Winforms has nothing to do with your question, will require you to worry about such silly things as multi-threading, timers, double buffering, geometry, etc and you'll have to write a lot of code. In WPF, you just attach an animation that animates the rotation angle from 0 to 360 degrees and you're done. 5 minute job max. ZERO code as it can all be done with one line of XAML.

What? While learning C#?

Could you show one line that does this? Either way, I am starting to lean toward the idea of WPF. Thank you, Steve

See DoubleAnimation http://msdn.microsoft.com/en-us/library/system.windows.media.animation.doubleanimation.aspx[^]. Ok, its a little more then one line :), but here is an easy example of animating the rotation transform http://www.galasoft.ch/mydotnet/articles/article-2006102701.aspx[^]

0 for the casino. 00 for the government? :confused: ;)
Heck no, the guv'mint takes more than that.

Thank you, That has gave me something to look over the weekend. Regards, Stephen

For a more realistic spinning roulette wheel (even on a slow system) use blurred intermediate images. These will give an appearance more like what a person would actually perceive seeing a real wheel spinning. Transition to actual images as the wheel slows down.

This sounds like a very interesting idea, however, I would not have a clue where to start by doing this. Would you possibly be able to provide a little more information please? Thank you, Regards, Stephen

This http://www.blackpawn.com/texts/blur/default.html[^] gives basic blurring algorithms, but they're rectangle-oriented, and you need to adapt them for rotation. So, instead of averaging in a rectangular region for each pixel, you'd use an arc representing a fraction of the roulette wheel's rotation, at the pixel's distance from the center +/- a delta constant.
