This version revised some poor logic code, now has 35 samples, list most of the funtions used in pixel shader programing, more textures can be loaded, more stable, and bug fixes. Please note - most video cards do not handle pixel shaders yet. If your does not, the result will stay black. This program has been tested on - Winows ME, 900 mhz, 128mb ram, 64 mb GeForce 4. Thats it. Please leave comments and suggestions. If you like it please vote. My next task is a pixel shader lab. -Enjoy-

I got thinking... What good is collision detection tutorials/demos if theres no tutorials/demos on bounding volumes? Thats the heart of 90% of the collision detection algorithms. This will show how to compute bounding box's and bounding spheres for an object. It also shows how to compute the distance from the center-center of the object and the edge-edge distance (Collision Distance). I made it in hopes this will help someone understand collision detection better. If it helps you or you like it please vote and please, please leave some feedback. Thanks everyone. -James-

This is a major improvement from version 1. When compiled it can change the bit depth in 0.02-0.08 milleseconds! Version 1 supported 1, 4, 8, 24(32k), 24(64k) bit depth's. Due to feedback I decided to add 15 and 16 bit depth's and redo all the code. The code is a lot cleaner, organized, and optimized to remove unnecessary repetition. MUST SEE! Please leave feedback, if you like it please vote. Enjoy! -James-

I have had a lot of e-mail recently on how to make and reference c++ .dll's in VB to optimize their game engine. This is my solution. A 27 Page Tutorial!! Also a DX demo for the C++ .dll and how to reference demo in VB. Must See! Hard to describe fully. The tutorial takes you step-by-step with screen shots. This took a while to make so if it helps you or you like it please leave some feedback and vote. Thank You... -James-

Thanks to Robert Rayment the VB version of TaylorDistance3D works right now. This is another way to test for distance if you don't like to use the Sqr() Function. Its the Taylor/Maclaurin Series. The only problem is theres a Max Error of 3.5% in 2D and a Max error of 8.0% in 3D. So if you need exact accuracy don't use this. This can also be found in Andre LaMothe's Book. "Tricks Of The Windows Game Programming Gurus" Enjoy. -James-

Awesome! Look at screenshot. Making it to be programmer friendly.. Features include - 2D Sound, 3D Sound, Midi(with soundFX's), SoundFX's, Transparent objects(even .x files),Partial Collision Detection(lol need to fix landscape Collision Detection - you climb up a hill when no hill is there :)) animated water, animated enviroment sphere, Object Filters(Dark Mapping, light mapping, gloss mapping, detail mapping, and much more), Enviroment Filters(Anistropic, Bilinear, ETC.) To much to list.. must see.. This is beta. Not complete yet Sorry for not commenting, I will on next version(I wanted to get it uploaded) PLEASE VOTE!!!! www.Bright.net/~james-d-21/ (there are no advertisments, Just download link)

Fixed the UI problem. Easier on the eyes. What does DDSCL_ALLOWMODEX do? What does DDSD_CAPS mean? This will help you to understand what everything does and what everything means. It also has a built in demo showing you how to blit, draw text, and figure FPS, agian fully commented to help you understand. I want to make more of these cause it also helps me to learn but if no one likes them I wont. Please let me know what you think and maybe I'll make a bigger tutorial and do a tutorial on what you guys want, Direct3D, DirectMusic, DirectSound, etc. Due to filesize and until I get my cable modem, this one is relatively short, but VERY HELPFULL. Let me know what you think of it. Enjoy -James-

Part 1 covers and explains Direct3D objects and how to use them. If you tried my DDraw Tutorial you'll love this one. Please leave some feedback good or bad, and if you like it or dislike votes are welcome. Thanks in advance -James-

This will help you keep track of all your "mules" items. It also show you how to load/save data from the tree view control with pictures(obviousley). This is a complete application. The registery functions are not mine and I forgot whos they are *sorry*, but I did put the names of the people who made the hacks(will and max). Check it out has some nice features. I made it for my friends. Tell me what you think, leave some fedback and vote please, Spent a lot of time on this. www.Bright.net/~james-d-21/ (there are no advertisments, Just download link)

This will change the depth of an image in the matter of milliseconds. This is as fast as PhotoShop. It includes the Visual Basic Source Code to the .dll and a demo to show how quick it is. I didn't have time to comment this. Its for a image editor I'm working on. Please leave feedback and vote if you like it. (If PSC deletes the .dll's just compile it and put one in the demo folder to run it) -James-

(BY REQUEST IT NOW PRODUCES ONLY UNIQUE PASSWORDS. ENJOY IT!!) This will create passwords any number of passwords you want with any mask. You can also create custom masks! Very simple and little code. Easily customizable. MUST SEE! If you like it please vote and leave feedback.

This will create any number of passwords you want with any mask. You can also create custom masks and now custom keys! Also checks to make sure the passwords are unique. Very simple to use. Easily customizable. IF YOU LIKE MY LAST ONE THIS IS A MUST SEE! If you like it please vote and leave feedback.

This control handles almost every aspect of DirectInput8, if not all! It handles the usual mouse and keyboard events, but it also supports joysticks with force feedback and regular joysticks. Also you can configure the devices (mouse, keyboard, and joystick) from within the code. It opens the Configuration Window. Has some sample force feedback effects I made to so you can test your joystick. I pulled this out of my new engine and I thought I would share it with everyone. Enjoy It. VERY EASY TO USE and comes with a demo.

This is a tutorial to help beginners understand 2D collision detection. Its not much, but if your a beginner you'll like it. Shows images and explains everything. Covers brute force and 2 bounding sphere examples. Enjoy! Please leave feedback.

This XMath class is a must have. It handles Collision Detection Functions (Distance, Object-Object Collision Detection, etc.),Color Functions, Vertex Functions, Matrix Functions, Vector 2 Functions, Vector 3 Functions, Vector 4 Functions, Plane Functions, Quaternion Functions, Actual PI, Inverse PI, 90 Degrees, 180 Degrees, 270 Degrees, 360 Degrees, Radiant, Epsilon, Huge Single, Radians to Degrees, Degrees to Radians, much more.. I dont care about votes but I would like some feedback please. FREEWARE...have a look :) Enjoy -James

This is a package I put together to help ease programming. This is a very VERY useful package. Look at the screen shot to see what all this one includes. This is package 1 and there will be more on the way if everyone likes this one. I will make updates often on this as I make updates on these systems in my engine. When I get more time, I will upload some demos for some of these. It also includes a PDF that helps explain what the different systems do. This package was ment for the kernel and systems part of an engine (A very little part) the next one will start on the graphics side. Systems Included In Package 1: Advanced Window System (Kernel Internal) Advanced Window System (Kernel External) Deprecation System Error System Log System Math System (Updated) Memory Controller Registry System Resource System Resource Creator Sound System String Files Timer System Version System This took me a long time to create and put together. If you like it or find it useful, please leave a comment and vote. It will be appreciated a lot. Thank You. Hope You Like This Package! -James-

UPDATED: Added an SQL injection prevention method, Added more documentation, and a few more minor changes. This code will show you how to prevent header injection, the method GET (only allow POST from a form), unauthorized domain access, and invalid agent access. You see a lot of SQL injection prevention methods and what not, but nothing to this level. This is a first on PSC I belive. If you like it please leave some feedback and vote.

This is a cool particle system. See screenshot. Fire(candle flame), energy, sparks, gun fire, fire flies, crazy 8, and circle. It also shows how to do a simple GUI with openGL. If you like this please vote or leave a comment. They are always welcome. -James- BTW-If you don't have an OpenGL video card this demo will run slow. (GeForce 4 64mb - 76FPS, my laptop - 22FPS)

This Visual Basic version was popular so I decided to upload the C++ version. This is my first C++ submission. Hope everyone likes it. This math library handles 2D Vectors, 3D Vectors, 4D Vectors, 3x3 Matrix, 4x4 Matrix, Color, and Quaternions. The 2D Vectors, 3D Vectors, 4D Vectors, and Color all have linear and hermit spline interpolation. Also, the vectors handle easy/advanced collision detection routines, advanced quaternion and matrix functions, and much more. This is 100% worked out math functions, no calls to DirectX or any other API's. (*Other than the normal Cos(), Sin(), Sqrt(), etc*) Not every functions has been tested yet, so if there are any problems please let me know. Enjoy this and learn! -James-

I needed a utility for my new game and Microsofts didn't work the way I wanted so I made my own. This one is better in many ways. First, you don't have to create a window or window procedure every time you make a new program, it does it for you! Second of all, it has fast set/get pixel for custom surfaces (ASM). It can also Auto Grab color keys so you don't have to worry about getting the right color key or not. A lot more... This is only version 1 and more updates will come. I uploaded this for hopes it will help someone. Enjoy it! -James-
