Game devs come out

As I go along developing CPool, there's still one problem unanswered. Here goes: The balls don't slide on the table, they spin across it (like car wheels). Calculating it wasn't too difficult, but the main problem is displaying it graphically. In a 3D game, you would model a ball object and display it from different angles. Being a 2D game, I find it difficult to show the ball from different angles without making loads of sprites. How do I make it seem realistic, so the ball would actually spin and not slide? Making a few sprites won't be very useful since the balls can spin on more than one axis. Anyone has a solution? Isaac Sasson, Lean, mean posting machine! Sonork ID 100.13704

I just had some idea, but I'm not sure on how to go about it. I could draw a bitmap of the ball surface spread (like a flat world map) and then display portions of it on the ball as it spins. It would be hard to implement though, because of the curves and perspective. Isaac Sasson, Lean, mean posting machine! Sonork ID 100.13704

Or you get down and dirty and create your own scanline ball renderer. It wouldn't be that hard. Todd Smith

Ok, I think I have your answer for you, at least if you are interested in doing any of this in C# :confused: Christian Graus (our local C# buddy) has written several article that I think should help you out in this subject. Maybe you can take a look at what he has done and adapt it to what you need. Here are the links below, of course all in [New Windows] Collision - A C# Game, part 1: parallax scrolling Collision - A C# Game, part 2: tracking game elements and adding interaction Collision - A C# Game, part 3: pixel perfect collision detection HTH Nick Parker

Create one set of sprite animations for the ball rolling, and I would say create the animations so the ball was rolling along the positive X axis, or 0 degreess. Then when a ball is to be rolled across the table, determine the angle that it is to be rolled at then create a temporary buffer for all of the ball animation sprites, and rotate all of the images by the angle of the direction that the ball is going to roll. So for example, if the ball is going to roll at an angle of 100 degrees from teh origin, create temporary sprites that have been rotated by 100 degrees, and the ball should look like it is rolling in that direction. the drawbacks of this technique is that you will not get the appearance of spin on the ball. But it should be a very simple trick. Just make sure that your rotation algorithm accesses the bits in the bitmap directly instead of Get and SetPixel. Good Luck!

No really. :rolleyes: ____________________ David Wulff I'll have a slow comfortable screw against the wall followed up with sex on the beach and a screaming orgasm on the rocks, please.

Light a man on fire, and he will be warm for the rest of his life!Good idea. I thought of making a grid of sprites, when on each row/line the ball makes one spin. Then changing the sprites across would simulate the spin. Your way is very similar, smaller on size but harder on the CPU. I'll have to try both and see which is most optimal.
