Okay, I have been attempting to, upon the world loading, to keep every chunk that a specific entity is in loaded. I have tried loading a chunk that I had placed the entity in, then see if it was loaded:

 

Minecraft.getMinecraft().theWorld.getChunkFromChunkCoords(11, 0);
System.out.println(Minecraft.getMinecraft().theWorld.getChunkFromChunkCoords(11, 0).isChunkLoaded);

 

But, that always returns false and the entity never updated. Perhaps I'm putting it in the incorrect place? I have tried it in the server and client tick events, as well as in an entity, but they all showed the same failure. Could anyone help/lead me in the correct direction? Also, is there a way to fetch all the entities in a world, even if the chunk hasn't been loaded as of yet?

Minecraft.getMinecraft() is client side.

 

I'm really not sure you can try using WorldLoadEvent (and do event.world to get the world instance and that might work better)

tickhandler, side server and type world?
