hi all,
my sandbox game develop have some questions:

1.

this game need many many cube entities.(like minecraft)
i try to:
var world_xyz[3] = { 1024,1024,1024 };
...
function main()
...
max_entities = (world_xyz[0] + world_xyz[1] + world_xyz[2]) * 10 + max_entities;
...
start no error, but run game when function create random world a few min ago display error:
to many entities!

how can i fix it?

my PC:
2 XEON,48GB RAM,GTX1080

---------------------------------------------------------
2.

i set all cube entities flags:
my.emask &= ~DYNAMIC;
works fine! too many entities can't display, but game render fps is very slow

how can i fix it?



thx all.

Hi,

max_entities = 10000; //fill in any value here

Please note though that you cant give all of them an active while() loop (only ~1000 or such). So use a global while() loop to e.g. update/change them, and the event system for e.g. push or impact events (just like normal entities).

I have tried something similar on time and its possible but not as high numbers as minecraft I think (unless you use some really complicated tricks to solve it).

hi i have done similar terrain as minecraft-like and marching cubes voxel based and normal height based based projects, in unity and gamestudio , i can only stress that your approach is on the wrong track , in the case where you wish to represent a lot of models /entities as fast as possible ,each entity must be rendered and that is way to much , you must fake it by joining the meshes or creating/building up a single mesh to represent all the cubes visible faces such that it takes only one mesh to be rendered instead of thousands ..

you need to research why and how.

similar thing can be, more exactly already made with Unreal Engine 4, by instanced static meshes and in more professional solution by procedural mesh generation. there is a tutorial how to make it, and maybe a marketplace item too... it requires really advanced optimizations.

, but where is the dirty-Acknexing in that?

I don't think it can be effectively made with 3dgs, it is better to choose the right engine for your game than to be tight by an engine's limitations. the strengths of 3dgs are located in other areas...

This is an old exemple like minecraft created by acknex 8 : https://www.youtube.com/watch?v=6vCf_g1cWGc

I created something like that a while ago. But not with a blocky world. I used marching octats (or something like that, I can't remember) to proceduraly generate the "natural" looking world.

I created chunks of terrain. Every Terrain hat three lod steps. But the big problem was that the realtime modification needed to be done on the cpu, because directx9 doesn't support this nice geometry features in shaders.

For blocky worlds it should not be so heavy on the fps to recreate the terrainchunk. But my guess is, that it will never be so fluent like minecraft or other sandbox games.

Another approach would be using a shader. You create a terrain-chunk with all possible faces and hide those which are not visible. But collision will be a nightmare then. And the polygons are still rendered even if they are not visible.

Use another engine with nice advanced shader capability.

, going a bit offtopic here, but what is that Alphabox you are developing? Looks interesting.

^-- He's been working on port platform to android for sometime. In fact HE posted about a early version that could convert any pure 2d 3gds game to android long ago. I'd say this is a next step and full evolution to 3d .. But just guessing.
