Thank you for the hint. I visualized the normal vectors and saw that they all had seemingly random orientations:

I printed out the calculated normals and visualized them by hand, confirming that they are actually all correct. I then changed my focus to the matter of actually sending this data to the…

@1negroup Is the whole screen flashing? I'm not familiar with xlib, but problems with flashing/flickering make me think you're not using double buffering or if you are using DB, you have an erase screen flag set as true when it should be false.

How do you define scripting language? I define it as a programming language that does not require a separate compilation step.

There are **very** few language definitions that define how to build an implementation. For example, while C is typically compiled as a sepa…

A major detail I notice in your code and since we're not in the For Beginners forum, you're not checking the results of scanf().

Input functions can fail for many reasons. For the scanf() family the return value is the number of items successfully matched and processed, or EOF in the result of failu…

Yeah, you will better off with OpenGL than DirectX. Especially for a beginner. You will be able to access more type and generation of platforms. The api is also far more simpler. 

@dpadam450 Yes you are right, I added a video of it

Hey there. I'm looking for programmers in c,c++,or c# that knows a bit about emulation programming. The idea is a portable (works on pc, web, mobile) fantasy console, with strict limitations on sprites per scaneline, controls and performance etc. Ideally i like to have at least two programmers for …

I also realised that gpu drivers and extremely low level gpu programming are some kind a ‘secret’ knoladge that nobody know how to do except the elit at vulkan and other specialised company that won't tell us there ‘secrets’. that's why I am asking : How to draw from gpu to the screen or …

It's over, I've finally completed my from scratch game project!

The final stretch has been far from glorious.

Rather than making features, it has been nonstop bug fixing.

To reach feature complete, I started just writing down non critical bugs rather than fixing them.

But after feature complete, I star…

Adding audio to my engine.  

I used OpenAL as the API is similar to OpenGL, the graphics API of this project.

I've added sounds to ship engines, lasers, explosions, UI, and more.

OpenAL makes Doppler effects easy, it just works out of the box.  

I know there isn't sound in space, but I'm take…

@hplus0603 I understand. I did some research and I finally got nullmodem working, though I got it working before I did some more research and also before I discovered that nobody is going to go through the trouble of buying a cord just to play multiplayer on a DOS game.

And if you want to see it for some reason, here is the entirety of the demo application. It looks long, but there are several defines for the different types of Watcom modes (I am using DOS4GW).

#include <process.h>
#include <stdio.h>
#include <stdlib.h>
#include <dos.h>
#inc…

ok ty
If other people want participate you can up this topic or pm me : )

@endurion 

Thanks for pointing that out. It has since been fixed.  ?

Visual Studio can be configured using any folder structure regardless how it looks like by adding all the files to the .vcproj file and in addition add a .vcproj.filter file. Here you can configure all your files to look nicely and even be addressed in “virtual folders”. We use this in our build to…

Hello gamedev.net!

The time has come for me to exit the shadows in which I lurked.

In the fall of 2017, I started going through some OpenGL tutorials and trying to put together my own renderer. It was fun. Maybe it was this feeling of fun that led me down the path that I followed. Here's one of the f…

The way I find up_tmp in init_camera_axis() is not optimal because if my cam->vec is (1, 1, -1) I can't find the right up_tmp. I currently find (0, 0, 1) and it should be equal to (-1, 0, 1). Do you have any idea how I can correct this ?

I had to normalize right and up.

Thank you very much for your help. 
Finally, this helped me :

I still have to calculate the angles and manage the interval.

I'm working on a game framework called tinycoffee (tico), programming in C and Lua, using OpenGL 3.2. The structure is very similar to LÖVE.

The library is in an initial stage, so i don't recommend using for a commercial project. I have plans to create a simple editor, and make smaller editors as mo…

If you know how to rotate points, you can rotate line segments, just by rotating the ends. If you know how to rotate points around the origin, you can rotate cpstest points around arbitrary points, by first subtracting the coordinates of the center of rotation, then rotating around the …

The buffer object simply isn't bound to the vertex array. The array doesn't know where to take the data from.

And a thing i don't understand:

glDrawElements(GL_TRIANGLES, layer->index * layer->ipo, GL_UNSIGNED_INT, 0)

How does the second argument relate to the number od elements ? Ipo is the buf…

@endurion 

I have tried XORing the flags and get different results. Probably a case of undefined behaviour? None of the docs really talk about XORing two modes together. Anyway, I finally understand how this effect is done, and it's pretty simple. I switched out one graphic for another, ran the…

Okay, a few of them. 

The code has structures that are the wrong size. Why do you have a 100 byte array to hold 3 bytes individually, which is much too large? Why are you building a large, potentially unbounded size string out of another 100 byte array which may be too small?  The first is…
