12:51a	ChatGPT translation Stumbled upon the following DirectX 5 example http://archive.gamedev.net/archive/reference/articles/article589.html It does some obscure shit. In particular, it inits palette to random colors // clear all the palette entries to RGB 0,0,0 memset(color_palette,0,256*sizeof(PALETTEENTRY)); // set all of the flags to the correct value for (index=0; index<256; index++) { // create the GRAY/RED/GREEN/BLUE palette, 64 shades of each if ((index / 64)==0) { color_palette[index].peRed = index*4; color_palette[index].peGreen = index*4; color_palette[index].peBlue = index*4; } // end if else if ((index / 64)==1) color_palette[index].peRed = (index%64)*4; else if ((index / 64)==2) color_palette[index].peGreen = (index%64)*4; else if ((index / 64)==3) color_palette[index].peBlue = (index%64)*4; // set the no collapse flag color_palette[index].peFlags = PC_NOCOLLAPSE; } // end for index So I asked ChatGPT to convert it to SDL2. And it decided to be smart.... for (int i = 0; i < MAX_COLORS; i++) { Set_Pal_Entry(i, (i % 64) * 4, ((i / 64) % 4) * 64, ((i / 64) % 4) * 64); } That was in fact the single broken part of it. Outside of the need to "#define SDL_MAIN_HANDLED" to suppress SDL from doing `#define main SDL_main /*happy debugging retards!*/` Anyway, the code is basically Etch A Sketch Current Mood: amused (Comment on this)
3:53p	Entity Relations Apparently the right way to implement relations is the by creating a relation table dynamically and adding there all ids satisfying the relation: https://ajmmertens.medium.com/building-games-in-ecs-with-entity-relationships-657275ba2c6c Basically we do ComponentTables["[Relation] [What]"].[EntityId] != NULL For example ComponentTables["is mortal"].[Socrates] != NULL In SQL people usually introduce secondary keys for that. But yeah, that requires very efficient and adaptive hash table implementation, since we can have millions of relations, having just a few elements each. I.e. doing unordered_map<int,int> won't cut it. Current Music: VNV Nation - When is the Future? (3 Comments | Comment on this)
