  1. Physics Question

    Quote:Original post by firelior well, If you want the object to collide and get back you could do with this physics equation: m1v1+m2v2=m1u1+m2u2 and more importantly: v1-v2=u2-u1 Because in physics the momentum is saved(google about it for more information).. A short explanation is that the mass of the first object which in your case is the box multiply by the velocity of the box should be equal to the mass of your box multiply by your velocity after the crash. Now, in your case the mass of the wall is probably too big compared to the box so you the velocity of the wall is near 0. So here is an equation for this: v1=-u1 Which means that the velocity of the box before the collision is equal to the velocity of the box after the collision, but on the opposite direction..that means that the object is moving back. Now, The rules that I told you up there only apply if you don't have any force that can subtract from the speed. If you do have some force than tell me and I will explain to you how to do that. Btw I now saw that you want also a collision with a box.. You do that with the rules I gave you above..to find the speed. I hope what I wrote helped you.. Thanks
  2. List of free libraries

    Quote:Original post by Spudder I would nominate CDX in the "General Purpose" libraries, I had a look at it a while back and it's a pretty decent library with many useful features. I agree!
  3. Book for christmas!

    Quote:Original post by DanielH Hello everyone! First I like to apologize if this thread is posted in the wrong forum. I couldn't find any more appropriate than this one, and it seemed to me the "Book Discussion" forum wasn't really a forum where you could post threads. So if it's posted wrong, please move it. :) Now to my question. Soon it's christmas and I have thought about wishing myself a game development book. I'm not quite sure what book I should buy though. I already know languages and 3D APIs good enought, what I need to learn is some deeper understanding of how to organize a real game - how to make a game engine. I've noticed that "3D Game Engine Architecture" (Eberly, David) have gotten good reviews, so I'm thinking about going for that. Do you guys think that is a good choice or is there any better or newer books to buy? Is a game development book from 2004 still up to date? My main language at the moment is C# together with Direct3D, is the book still good for me? I'd love to get other tips of good game programming books aswell. Thanks! :) I am getting a Game programming book aswell! Well let me sat Books I can't wait!
  4. C++ Workshop - Introduction

    Quote:Original post by Alpha_ProgDes It sounds like a great idea. Most likely for it to be somewhat coherent and organized the Staff are gonna have to give you your own forum. The Lounge won't cut it, I'm afraid. I'm pretty sure if Lazy Foo isn't too busy that he might be interested. Indeed.
  5. Hey, guys

    What is the most easy software to learn I am having a hard time with Photoshop. I am studying programming.
  6. Thanks a lot for the info I am writeing a story right now
