![]() This could represent either sky or ground. The entire initial world can consist of zeroes, or structures all of whose members are set to zero. speaking here in a general sense of the techniques used to generate large worlds (not Terraria specifically).įirstly, there are fast block copies ( memcpy / memset in C) used to allocate the initial memory (2D array) representing the world. ![]() so when you're moving fast, you sometimes see the tiles ahead of you needing some time to appear.Ĭouple of additions to Steven's informative answer, at a technical / processing level. The world is technically generated in one go, but it keeps generating new parts over itself, and finetuning the details afterwards.Īs for rendering, while the world is loaded all at once, it will only draw (or render) the blocks when you're close to it. After that you'll also see sections been converted to biomes (jungle and ice specifically), and then more detailed structures, like granite, cabins and the dungeon happens afterwards. It starts out with the surface, and the variation of the dirt and stone, then it start making caves, increasing in size each time. So that gives you a rough idea how it's creation works: ( ) ![]() I've seen a video that showcases how the world generation looks like behind the scenes.
