  1. Draw a Textured Quad

    Yes, I've compiled it a couple of times and it builds successfully, the window appears and there's something drawn, but it draws realy strange (see image in previous post). I'll move on to DirectX11 instead. Exciting [img]http://public.gamedev.net//public/style_emoticons/default/biggrin.png[/img]
  2. Draw a Textured Quad

    Thanks very much for your help ATC [img]http://public.gamedev.net//public/style_emoticons/default/smile.png[/img] I've heard of different wrappers of DirectX for C#. The reason that I chose C++ and DirectX anyway, is becouse many companies in the game industry uses it. As I'm a student, having knowledge in these areas can be a very good qualification when it's time to search for a job. I'll take a look at the link and try a little bit by my own again. However I recently tried to get it work with DirectX11, but problems accured and I guess that they will this time too. If so, I'll send you a pm so you can help me. Thanks again so much for your help [img]http://public.gamedev.net//public/style_emoticons/default/smile.png[/img]
  3. Draw a Textured Quad

    Thanks for your reply ATC. I actually wanted to learn DirectX11, but I havn't managed to find any good tutorials about textured quads. The only tutorial I found was really overkill, using shaders etc. I would really like to learn DirectX11, but could you help me to find any totorial that just picks the absolutely neccessary to draw a textured quad? I'm already familiar with encapsulization and separating into classes as I have 5 years experience of C# and XNA. I just felt that I wanted to move on with something more advanced than XNA, and therefore decided to learn C++ and DirectX. I know that the code should be splitted into classes, but before I do that, I just want everything in one place so I can overveiw it easy. The only purpose of the current project is so I learn the simpliest basics. When I've learn these, I'll move along with a new project where I'll split the code into classes and learn more complicated things. Could you please help me find a good tutorial with [i]only the absolutely neccessary steps[/i] to render a textured quad in DirectX11? Or, if you want to be very kind, would you like to spend like 10-15 minutes and write a short tutorial with the absolutely neccessary steps?
  4. Draw a Textured Quad

    Thanks for your reply Waaayoff. I've added the file extension, ".png". I'll look deeper into error checking, while I do that; I've done some minor chages to the code again, and there's actually something appearing on the screen now, however, the texture just looks strange.

  5. Draw a Textured Quad

    I've tried to rewrite everything, so now it atleast appears a quad. However, the quad isn't textured but instead some sort of a gradient with black and red.

  6. Draw a Textured Quad

    Hello everyone! I'm trying to draw a textured quad made from 4 vertices using DirectX9. I've followed some tutorials but it simply wont work. I've pasted the code below and I would appreciate it very much if someone could look through it and help me. I know that the code should be splitted up into methods and classes, but before i do that I want to keep it as simple as possible and be able to see and learn the entire process. What i want this code to do is to simply draw my quad with a texture on it. Could anyone please help me?

  8. [C# XNA] Pixel Collision

    Hi! The method below is from my project that uses pixel collision. The collision "works", but I'm encountering a bug during the test. When the collision is detected on the right and bottom side of Texture1, the pixel collision works perfectly. However when the collision is detected on the left and top side of Texture1, Texture2 has to intersect with half it's size before collision is detected. I've added the entire project if you would like to take a look and below is the collision method. Please help!

    I'll take a look at the code, thank you Meanwhile, what about keeping the images original proportions? I tried to set the width and height manually in my code, but it still rounds?
  14. Sprites and D3D9

    My stationary computer supports D3DX_DEFAULT_NONPOW2, but my laptop does not [img]http://public.gamedev.net/public/style_emoticons/default/sad.gif[/img] Is there any way (that is supported on all computers) to draw an image with it's original proportions? I'm trying to find a solid solution that will support three things: 1. png images with transparent parts 2. sprite sheet animation 3. rotation (and of course original proportions) Based on this, which way should I choose? There has to be something that support this 3 things, or? Thanks everyone for helping

(I'll also add the error checking) Then I also have 2 more questions: 1. I've noticed that the texture is scaling to the closest 64x64, 128x128, 256x256, 512x512, 1024x1024 etc. If my texture is 300 in height, it's going to be scaled to 512 in height. Can I disable this somehow? 2. What do [i]you[/i] think is better? Using Sprites or setting up vertices? @ryan20fun: Ok, I've checked the Debug Runtime Version. Should I do anything with the Debug Output Level? Where will I find this debug help in Visual Studio when I work? Thanks for helping!
