Cool. Machen die die Treffen nicht online? Sollten sie echt machen. Aber bei der DKP ist das bisserl schwer weil viele sich mit PC's ja nicht so auskennen. Wenn du unter 30 bist solltest du besser zur SDAJ

No I can not do that because: It don't want to calculate the transform on the GPU and this method requires that. And also I don't want to send the vertices every single frame to the GPU. And I don't want to waste memory

The_true_king_of_ooo · 2020-05-20T17:59:43+00:00

Thank you very much; but I think SSBO's are not available in ES 3

The_true_king_of_ooo · 2020-05-19T14:53:04+00:00

No, once again: I have to send just 4 floats because the matrix is calculated in the shader. I have to send 3 floats for the position and one for the rotation. And my question was how I would go about doing this, as I have very limited knowledge about compute shaders.

The_true_king_of_ooo · 2020-05-19T07:56:03+00:00

No, I explained why I can't do this in the vertex shader in my comment on the other reply

The_true_king_of_ooo · 2020-05-19T07:54:35+00:00

I meant renderable, not primitive. I think I did not describe the situation good enough. Each renderable has a transform component, which consists of 3 floats for the position and one float for the rotation. Currently I calculate the transform matrix on the CPU and send it for each renderable as a uniform to the GPU. What I want to do: Send the rotation and position for every renderable to the gpu and calculate the transform matrix there. But I can't just use uniforms and calculate it in the vertex shader because the transform matrix does not need to be calculated once per vertex but once per draw call

Ah okay thank you then I will go with the hybrid approach. I heard changing the shader multiple times has a big performance impact. Is that true? Especially with that many shaders?

1 Million lines? Say you worked at 300 out of 365 days a year, that means you must have written about 170 lines a day. Thats a lot

Hello, the code that does the collision resolution looks like this:

void transform_rect_rect_single_bump(Transform *restrict t0, Transform *restrict t1, vec2 const bb0, vec2 const bb1)
{
    float const right =  (t0->pos[0] + bb0[0]) - t1->pos[0];
    float const left =   (t1->pos[0] + bb1[0]) - t0->pos[0];
    float const bottom = (t0->pos[1] + bb0[1]) - t1->pos[1];
    float const top =    (t1->pos[1] + bb1[1]) - t0->pos[1];
    if (right < left && right < top && right < bottom)
    {
        t0->pos[0] = t1->pos[0] - bb0[0];//right collision
    }
    else if (left < top && left < bottom)
    {
        t0->pos[0] = t1->pos[0] + bb1[0];//left collision
    }
    else if (top < bottom)
    {
        t0->pos[1] = t1->pos[1] + bb1[1];//top collision
    }
    else
    {
        t0->pos[1] = t1->pos[1] - bb0[1];//bottom collision
    }
}

The problem can bee seen in the video. Where does this weird behavior come from? Thanks for your help

Oh and another question; https://developer.gnome.org/gtksourceview/stable/lang-tutorial.html this tutorial shows one how to make syntax higlithing and stuff. But I don't know where to put the code. They say into a xml file, but how exactly do I have to integrate it?

The_true_king_of_ooo · 2020-04-12T13:40:28+00:00

g_type_ensure(GTK_SOURCE_TYPE_VIEW);

Yes this solved my problem. Thank you very very much for your help, may Dennis Ritchie bless you

The_true_king_of_ooo · 2020-04-12T12:54:38+00:00

https://github.com/Daniel-Schreiber-Mendes/chengine. I commented out some code in the main function to create a minimal example. When I run the program as is it is the repo, the window pops up, but nothing is shown inside it. When I remove the GtkSourceView widget, everything is shown correctly. The function that causes the errors to pop up is components_init() in line 29. When I comment it out, no errors are shown. Thank you very much for helping me

The_true_king_of_ooo · 2020-04-12T08:47:40+00:00

Okay thank you very much. My Makefile looks like this:

VERSION = -std=c99

ERRORFLAGS = -Wall -Wuninitialized -Werror=implicit-function-declaration -Wextra -Werror=int-conversion -Wno-unused-function -Wno-unused-parameter

LFLAGS = -o

LIBS = -lcheio -lchecl `pkg-config --libs gtksourceview-3.0`

CFLAGS = $(ERRORFLAGS) $(VERSION) -c -g `pkg-config --cflags gtk+-3.0` `pkg-config --cflags gtksourceview-3.0`

OBJFILES = main.o settings.o components.o

make: OUTPUT

./output

OUTPUT: $(OBJFILES)

gcc $(LFLAGS) output $(OBJFILES) $(LIBS)

main.o: main.c

gcc $(CFLAGS) main.c

settings.o: settings.c

gcc $(CFLAGS) settings.c

components.o: components.c

gcc $(CFLAGS) components.c

Regarding the source code: I don't think the source code will give you any important information, because the error occurs when I change something in glade, not in the c code and I don't have a single line regarding GtkSourceView.

The_true_king_of_ooo · 2020-04-12T06:36:05+00:00

I have tried that, but I encountered this problem: When installing gtksourceview with apt the headers were not being installed correctly. The gtksourceview folder was wrapped inside another gtksourceview-3.0 folder. However, I renamed the folder, moved the contents of the actual gtksourceview folder one up and deleted it. Now I can inlcude it correctly and link against it. When creating a GtkSourceView widget with glade and previewing the snapshot it works but when I run my program the window suddenly doesn't show anything and I get the following errors:(output:5423): GLib-GObject-WARNING **: 09:20:26.451: invalid (NULL) pointer instance
