man I spent like 20 minutes trying to fit those two together.
cmon.

Hi !
I've got this error when compiling almost all demos :
[DEBUG] (src/casset.c:folder_load:308) Loading Folder: '/home/oki28z/git/Corange/demos/rendering/assets/podium'
[DEBUG] (src/casset.c:file_load:282) Loading: '/home/oki28z/git/Corange/demos/rendering/assets/podium/podium.mat'
[DEBUG] (src/casset.c:file_load:282) Loading: '/home/oki28z/git/Corange/demos/rendering/assets/podium/podium.dds'
[ERROR] (src/assets/texture.c:dds_load_file:572) OpenGL Error: Invalid Enum

How can I fix it ?
Thanks for your help :-)

Hey, I tried to compile one of the demos with Makefile but -l corange was not found. What can I do?

I've just made a clone, the HEAD is at 841fcf6 and when running make I get the following error:

[karol@localhost 13-01-10 21:26 Code/Corange]> make
gcc src/cengine.c -c -I ./include -std=gnu99 -Wall -Werror -Wno-unused -O3 -g -fPIC -o obj/cengine.o

make: *** [obj/cengine.o] Błąd 1

The SDL_GL_LoadExtension macro is looking for NULL return to determine extension availability, that could have undefined behavior.

From the SDL2 reference manual
"if you look up a function that doesn't exist, you'll get a non-NULL result that is NOT safe to call", for Linux at least.

A more correct form would be something like:
#define SDL_GL_LoadExtension(type, name)
if (SDL_GL_ExtensionSupported(#name))
name = (type)SDL_GL_GetProcAddress(#name);
else if (SDL_GL_ExtensionSupported(#name"EXT"))
name = (type)SDL_GL_GetProcAddress(#name"EXT");
else if (SDL_GL_ExtensionSupported(#name"ARB"))
name = (type)SDL_GL_GetProcAddress(#name"ARB");
else
fprintf(stderr, "Failed to load any of function '%s*')\n", #name);

In any case, I found this problem because when trying Corange I can't load any of the extensions. For instance, glCreateProgram* does not exist in the extension list of glGetString(GL_EXTENSIONS) and SDL_GL_ExtensionSupported() returns false for it as well.

The context is a 4.5.0, im on nvidias latest propietary drivers (gtx880). Any idea why?

I recently asked another question about the "quadratic()" function, but I have another one about the implementation. This function obviously lets one use the quadratic formula, which is x = (-b +- sqrt(b^2 - 4 * a * c))/2a. Please see this Khan Academy if my quadratic formula is unclear. This is almost reflected in the code, but instead of "2a," it appears to divide the discriminant by just "2." Why is this? I'm fairly new to computer graphics math, so I am unsure if this is intentional or not.

Here is the code from Corange that I'm asking about, with the parts I'm curious about followed by a comment.
`bool quadratic(float a, float b, float c, float* t0, float* t1) {

float descrim = bb - 4a*c;

if (descrim < 0) {

return false;

} else {

float d = sqrtf(descrim);
float q = (b < 0) ? (-b - d) / 2.0 : (-b + d) / 2.0;//  Should "2.0" be changed to "2.0*a"?

*t0 = q / a;
*t1 = c / q;

return true;

}

}`

I'm not experienced at C command line compilation; compiling for Windows, attempted from both Windows MSys2 and Linux platforms with same error. Only change to code was the CC and AR variables in Makefile. I'm not sure if the problem is me, or that I'm the only one compiling this way:

CC=x86_64-w64-mingw32-gcc-8.3-posix
AR=x86_64-w64-mingw32-gcc-ar-posix

I downloaded the mingw SDL, SDL_mixer, SDL_net libraries and just copied the headers into the .include/SDL2 folder manually
This is the "make" result:

make: *** [Makefile:43: obj/cengine.o] Error 1

You get a lot of linker errors like

/usr/bin/ld: obj/cengine.o:/home/src/src/unix/Corange/./include/cengine.h:80: multiple definition of `debug_str'; obj/casset.o:/home/src/src/unix/Corange/./include/cengine.h:80: first defined here
/usr/bin/ld: obj/cengine.o:/home/src/src/unix/Corange/./include/cengine.h:79: multiple definition of `debug_buf'; obj/casset.o:/home/src/src/unix/Corange/./include/cengine.h:79: first defined here

The problem is that the cengine.h header defines global buffer variables, that are compiled into each file:

#define ERROR_BUFFER_SIZE   2048*4
#define DEBUG_BUFFER_SIZE   2048*4
#define WARNING_BUFFER_SIZE 2048*4

...

char error_buf[ERROR_BUFFER_SIZE];
char error_str[ERROR_BUFFER_SIZE];

char warning_buf[WARNING_BUFFER_SIZE];
char warning_str[WARNING_BUFFER_SIZE];

char debug_buf[DEBUG_BUFFER_SIZE];
char debug_str[DEBUG_BUFFER_SIZE];

There are two quick solutions

• turn them into declarations with extern in cengine.h and define them in cengine.c once
• make these buffers local variables to the block, like so:

#define error(MSG, ...) { \  
  char error_buf[ERROR_BUFFER_SIZE]; \
  char error_str[ERROR_BUFFER_SIZE]; \
  snprintf(error_str,(ERROR_BUFFER_SIZE-1), "[ERROR] (%s:%s:%i) ", __FILE__, __func__, __LINE__); \
  snprintf(error_buf,(ERROR_BUFFER_SIZE-1), MSG, ##__VA_ARGS__); strcat(error_str, error_buf);    \
  error_(error_str); }

This is thread-safer as a bonus, but putting 16K on the stack seems somewhat excessive.

Here:

I don't understand why you do time = fmod(time, a->frame_time * (a->frame_count-1)); and then (time / a->frame_time) + 0 for the first frame.

Because this line sets the "repeat_type" of "i" to "IMAGE_REPEAT_BLACK" it causes the calls to "image_set()" here to not modify the image.

Let me know if you'd like me to provide anything I might've missed.

The current setup for materials sucks. The syntax is bad and having two different asset types for materials and multi-materials is a hack.

Ultimately I don't want to bring in an external library for parsing so the syntax needs to be as simple as possible but I'd also like it to be uniform and relatively C-like.

Some other issues:

• Material Entry duplication - There is lots of replication in material files, in particular for shader listings.
• Shader Program duplication - Because there are no longer program assets each material uses a new program even if not unique. This wastes GPU memory.
• Internal access - Dealing with materials in the C code also is horrible.
• Blurry Concept - Because they are used by deferred and forward renders, materials are a horrible blurred concept. Should deferred using a different asset type? One that isn't so catch-all?

I've been adding explanations, mostly for file handling to the wiki. What other stuff would be missing?

Is there any chance to add CMakeLists support for this project?

Hi Daniel, can you help me?
I do not understand if the problem is related to the engine or the fact that I am an idiot)) I try to make a parallax map, but I have a lot of distortions, if I do the calculations in the vertex shader, and if I do them in fragmentary shaders, then everything is correct only displayed on two sides of the cube. I added a video where everything is visible and the shader code

I have been suffering for a week, I do not understand how to fix it Maybe this is a feature of the data in the engine and I just do not notice?

What could be the issue

Take the build files such as the executables and libraries out of the repo and set up makefile system for building proper distributions.

Makefile targets install_unix, install_win32 and install_win64 don't install header files.

The bird in the platformer has weird movement, it doesn't seem intuitive, it seems to accelerate either too little or too much.

It would be a good idea to make the buttons add acceleration to the velocity, and not edit the velocity 'directly'.

Hi, I was playing with the implementation of local reflections in the screen space. I did it, not quite a good but minimal implementation. At first I wanted to make a demo or embed this in the render, but since not everything works perfectly, I just leave the construction processing and shader functions here, if anyone is interested, they can just replace the shader and the engine function and it will work. It just might be useful to someone. In my fork for experimenters, I will continue to try to make a good implementation which can then be offered as a demo or as full support for rendering.

In its current form, any object can become mirrored if glossiness = 1 is specified in its 3Dobject.mat material

The exact same function "quadratic()" is defined in the exact same way in two places: in cengine.c and cphysics.h/cphysics.c. Is this intentional? I could probably fix this if it isn't.

Hi @orangeduck :)
It's been a few days since I'm trying to get this to work, I use elementaryOS in VMWare Workstation, I installed SDL libs and compiled it compiles clean, now I seriously don't know if it creates an executable or what, though I tried executing the compiled files, no luck though. I now know it compiles to a library(much like a dll on Windows).
Anyway metaballs didn't compile. Rest compile but don't run(execute but don't render) except for Platformer(cool game) and sea(really bad graphics don't know why). I think it's because of virtual machine, that's why it can't use my GPU to render out things properly?

That's why I returned to Windows 10, installed SDL dev libraries for Visual Studio(my main IDE), tried my best, couldn't get it to work. Tried other things with SDL, they worked like a charm, Corange didn't.

Next came MinGW, installed dev libraries, linked them. tonnes of errors(redefinitions and what not in SDL_Local.h, SDL_Local.c and SDL_opengl), fixed an error by commenting a block of code, worked and it compiled almost every src to obj except it stuck somewhere in the end, now can't fix that one. Fiddled, but no luck.

Can you please help me?
Do you happen to have a Visual Studio project of Corange? Are you able to run it MinGW?
If yes! help to do so too!

PS: I recently completed your book! It was an excellent source of learning C, please do check my repositories for my Lispi, well wait here's the link Lispi.
Thanks

I haven't had any luck so far and I would appreciate some help!
My attempts so far have lead to errors and failure.

I think short (2 bytes) is maybe a little bit to much for a boolean type.

Should I be linking with a different library or do I manually have to go and redefine all the functions?

I tried make with GCC 4.8.4 on my Ubuntu 14.10 box 64-bit, and I have SDL2 and SDL2-mixer and SDL2-net previously installed including libsdl2-dev. Is it simply renaming the file to something else? SDL_mixer to SDL2-mixer? PS: I bought your book, so I was pleasantly surprised to stumble upon Corange!

Hello, Daniel!
This file https://github.com/orangeduck/Corange/blob/master/demos/scotland/assets/terrain/heightmap.raw What is this file format? Just a binary blob? But if so, what is it created in?

P.S. I apologize for my English ::)

Could you clarify if the direction of the planes in a box are pointing outward or inward?

I know Dan, isn't maintaining this project anymore but if anyone else is interested in Android support this is what I've got:
My Android.mk file is:
https://github.com/gwald/my-corange-demo/blob/master/Android.mk
There's a few hacks I had to do:
1, creating SDL2 folders with hearders for SDL source, due to code having <SDL2/sdl.h>
2, in file: jni/corange/src/SDL2/SDL_local.c comment out line 15: #include <execinfo.h>

Anyway, that's really hacky, not sure what's the best way forward, but it works, kind of :/
I'm not an Android expert, nor anything else really!

I was hoping to target GLESv2, but v3 gives errors.
Using android-19 which has GLESv3

before I was able to use make I had to create the obj folder by hand. no big deal but could irritate some beginners...

Unfortunately I have several issues compiling and executing the demos under Ubuntu:

I can compile platformers, renderers, scotland and sea but when I execute them I get these messages:
[DEBUG] Starting Corange...

This is just a note for those who will be affected by the problem like mine. This is not Corange problem.
But it's better to know about it.

The problem is described here:

• https://gitlab.freedesktop.org/mesa/mesa/-/issues/7780

I will only briefly summarize the main.
If you come across artifacts and graphics options like in graphics.cfg lighting = 1 and while in the terminal you see the following lines

EE ../src/gallium/drivers/r600/r600_state_common.c:961 r600_shader_select - Failed to build shader variant (type=1) -1
EE ../src/gallium/drivers/r600/r600_shader.c:193 r600_pipe_shader_create - translation from TGSI failed !

it means the shader is working now assets_core/shaders/deferred/compose.fs

4 fix options

• 1 Fix shader

#version 120
-#define MAX_LIGHTS 32
+#define MAX_LIGHTS 8

or

-#version 120
+#version 130
#define MAX_LIGHTS 32

• 2 Use NIR backend

$export R600_DEBUG=nir
$run_corange_app

• 3 Wait update MESA with NIR by default

• 4 Set in graphics.cfg lighting = 0
  for use assets_core/shaders/deferred/compose_low.fs
  Notice: shadows not working with lighting = 0 and again wait update mesa

I hope this will be useful to know and someone will be protected from tedious debugging like me 😃

After a short while, the ellipsoid disappears. I put a printf into sea_update() to see what happens to the ellipsoid's position and saw the coordinates decreasing until they hit nan at which point the disappearing happens. What's causing this? Is this part of why the physics demo adds its own physics functions?

I didn't see any of the balls disappear (although the ball count seems to be off by one) in the physics demo, and since they're constantly bouncing, I think it could be a gravity handling problem

There are bindings for vala language

It would be nice to show what's possible.

I really like your engine :) Pure C ... nothing else to be said.

One Question:
https://github.com/orangeduck/Corange/blob/master/demos/rendering/assets/imrod/imrod.ani
How did you create the .ani files ? Everything else is Wings 3D .. but Wings cant do .ani? correct me if I'm wrong.

Is png a format the developer wishes to support? I've had to add a handler for pngs that uses libspng, I can create a PR to add it to the main project.

Hi, Daniel, I suddenly found that I did not understand how to adjust the angle of the camera.
I wrote a dynamic environment for a cubic map and for rendering in a cubic texture, I move the camera to the object position, but I don’t understand how to rotate the camera on six sides.

Can you give one example, for example, turning the camera
strictly up or down? And then I'll find out.

I have attached a piece of code to understand what I'm trying to do.

// prepare env cubemaps for surfaces
static void renderer_render_target_cubemap(renderer * dr)
{
    renderer_cubemap_dynamic_reset_counts(dr);
    vec3 cam_pos_save = dr->camera->position;

  for ( int j = 0; j < dr->render_objects_num; j++)
  {
    renderable * ren = NULL;
    if(dr->render_objects[j].type == RO_TYPE_STATIC)
    {
        dr->camera->position = dr->render_objects[j].static_object->position;
        ren = asset_hndl_ptr(&dr->render_objects[j].static_object->renderable);

    }else if(dr->render_objects[j].type == RO_TYPE_ANIMATED)
    {
        dr->camera->position = dr->render_objects[j].animated_object->position;
        ren = asset_hndl_ptr(&dr->render_objects[j].animated_object->renderable);

    }else if(dr->render_objects[j].type == RO_TYPE_INSTANCE)
    {
        //XXX: dynamic env only for one instance fix it!
        dr->camera->position = dr->render_objects[j].instance_object->instances[0].position;
        ren = asset_hndl_ptr(&dr->render_objects[j].instance_object->renderable);

    };
    GLint current_cube_texture = -1;
    for (int i = 0; i < ren->num_surfaces; ++i)
    {
       material_entry * me = material_get_entry(asset_hndl_ptr(&ren->material),i);
       if(material_entry_item(me,"envcube_dynamic").as_bool == false)
       {
            continue;
       }else{
           current_cube_texture = renderer_get_cubemap_dynamic_repare(dr);
       };
    for (int i = 0; i < 6; ++i)
    {
      
          swith(i)
          {      // help me this pleeeeeeeeeees ))))))))))))))))))))))
                 case 1:  dr->camera->target = /*????????*/ ;  break;
                 case 2:  dr->camera->target = /*????????*/ ; break;
                 case 3:  dr->camera->target = /*????????*/ ; break;
                 case 4:  dr->camera->target = /*????????*/ ; break;
                 case 5:  dr->camera->target = /*????????*/ ; break;
                 case 6:  dr->camera->target = /*????????*/ ; break;
          };
     
       dr->cubemap_dynamic_render_process = true; 
       render_shadows(dr);  
       render_clear(dr);    
       glPolygonMode( GL_FRONT_AND_BACK, dr->mode);
       render_gbuffer(dr);  
       glPolygonMode( GL_FRONT_AND_BACK, GL_FILL );
       render_ssao(dr);   
       render_skydome(dr);   
       render_skycube(dr); 
       render_compose(dr); 
       glPolygonMode( GL_FRONT_AND_BACK, dr->mode);
       render_sea(dr);    
       render_particles(dr);
       glPolygonMode( GL_FRONT_AND_BACK, GL_FILL );
       render_tonemap(dr);  
       render_post0(dr);    
       glBindFramebuffer(GL_FRAMEBUFFER, dr->cubemap_dynamic_fbo);
    glDrawBuffer(GL_COLOR_ATTACHMENT0 + i);
       glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
       glFramebufferTexture2D(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0 + i,
                              GL_TEXTURE_CUBE_MAP_POSITIVE_X       + i,
                              current_cube_texture, 0);

       render_post1(dr);    
    glBindFramebuffer(GL_FRAMEBUFFER, 0);
       dr->cubemap_dynamic_render_process = false;

    };

  };
 };
    dr->camera->position = cam_pos_save;
    renderer_set_camera(dr,dr->camera);
}

Next just render scene

Currently asset reloading is causing a bunch of issues.

The main issue is that objects which store direct pointers to assets (E.G renderable->material) get invalidated if somewhere else in the system the asset pointed to is reloaded.

It seems that objects sharing assets in unavoidable so this reloading is always going to happen in one form or another. Unless very careful steps are taken this will increase to be an issue. I see a few options:

1. Ensure objects never hold pointers directly to assets.
This solution is annoying because it causes a performance overhead (in the lookup) and forces objects to store string identifiers which means more memory management and are just generally a pain.
An alternative to string identifiers is to store a pointer to an asset pointer. If this were the case the asset manager could still manipulate the second pointer and change it at reload time. This is faster and less hassle than storing the string identifier but still a pain, and still relies on policy that no object holds pointers directly to assets.

2. Ensure assets reload into the same location.
This is appealing for many reasons but it rings alarm bells in my head because I am sure there will be unforeseen issues. It would require some serious adaptions to the asset manager but should be viable.
One potential issue is that pointers inside an asset struct become different on reload. But providing no exterior objects hold pointers one level deep into an asset this should be okay.
Another issue is that if someone does an "unload" and "load" rather than a "reload" it is impossible to ensure the asset is loaded again into the same location and so it may still cause invalidation.

Until more bright ideas come up I will continue in consideration.

Hi Daniel,
I'm looking at extending Corange, I don't mind sharing/uploading my changes etc.
So I thought I would ask you first before I hack it horribly.

Just wondering if you can advise regarding adding animation blending, ie top and bottom biped animations.
I'm still new, but I know my way around, so just any general points would be helpful.

Cheers
gwald

I read code bmf_load_file but i don`t understand it (
maybe you prompt me what is it? that the specification for him? ::)

src/assets/config.c: In function ‘cfg_save_file’:
src/assets/config.c:75:8: error: trampoline generated for nested function ‘write_entry’ [-Werror=trampolines]
   void write_entry(void* x) {

Also fails on versions 4.7.3 and 4.9.2

In the "cengine" code, the types "mesh" and "model" are defined to handle 3D objects. That makes sense, but what puzzles me is why these types are never used in Corange itself. Instead, whenever the engine actually deals with 3D objects the "cmesh" type gets used instead. Furthermore, "cmesh" does not use "mesh" nor "model" internally to represent it's structure.

My question is, why then do "mesh" and "model" exist at all? Should "cmesh" be changed to internally be based on "mesh"/"model"? I'm curious about the reason it was designed this way.

After following the trail of the includes through the sound advice offered here: #66

I found myself in a chicken vs. egg dilemma. Apparently--although SDL targets MinGW with it's releases--this issue from 2016 is still encountered whether compiling on Linux for Windows, or on Windows for Windows, when using MinGW:

https://discourse.libsdl.org/t/glactivetexture-declaration/22001

For now, I've commented out the offending
"GLAPI void GLAPIENTRY glActiveTexture( . . . . . ." ,
"GLAPI void GLAPIENTRY glCompressedTexImage2D( . . . . . .",
"GLAPI void GLAPIENTRY glTexImage3D( . . . . . ."
lines in SDL_opengl.h with success.

I plan to follow the advice in the link above and wrap it all together in a block of

#if !defined(__MINGW32__)
[ . . . ]
#endif

as that is the verified preset #define flag on at least the Windows .exe version of MinGW.

After compiling demos and executing them, I get the following error...

Any help would be appreciated..
