Somebody would have an idea of how I could create a grid with c2 ? Because i make a sandbox multiplayer game
Thanks.
Use arrays for it.
Also C2 have now build in Tile Map - this could be use for you as well
Develop games in your browser. Powerful, performant & highly capable.
If you don't know how to make a grid, I would really recommend trying something a bit simpler than a multiplayer sandbox... Try the tutorials...
