How would one go about getting all the entities in the world, that includes ones that are not within the clients render distance.

Any pointers would be greatly appreciated

Jokes aside, what are you exactly trying to do that requires you to get all the entities. As there are A LOT of entities.

I'm making a fun mod for me and my friend that will every 10-20 minute (haven't decided yet) it will swap entities position around, the mod should also work in singleplayer thus why i need to be able to do it client sided aswel

Please define "client side"!

If you don't have access to server - you will not be able to swap their positions (or even grab them all for that matter).

 

EDIT

 

Hint:

SP is MP with one player online (there is server in background).

Yeah sorry i meant the server side as i forgot SP is MP now (haven't modded in a long time)

1. @SubscribeEvent to WorldTickEvent.

* Remember to pick event.phase, or code will run twice!

* I am not sure if WorldTickEvent is fired on both sides, or maybe only server - if on both, make (!world.isRemote) check to run it ONLY on server.

2. Use Random (event.world.rand) to fire your code every "some" time.

3. To access all entities you can use World#entityList (or some getter, look into World.class and you will see entityList)

4. To teleport them you can call entity.setPosAndUpdate (since you are on 1.7, I don't know exact name, but something like this).

It's server side and you'll want to check the phase (pick either Start or End, probably start).

 

Do be aware that you can only teleport entities in loaded chunks.  You won't be able to shuffle about entities in chunks that the server does not currently have in memory.

To get all entities in the world, I think you need to load all chunks in the world. That would be a nightmare (in an old MP world that has been widely explored, you'd exhaust memory and/or choke the CPU).

 

However, there may be a way to tease out some knowledge of all entity IDs in the world and pick one before getting the entity itself. Unfortunately, except for players, that might not tell you where the entity is so you can load its chunk and teleport it.

 

Perhaps you'd consider a less ambitious effect: If there are 2 or more players in the world, and if they are a minimum of ~200 blocks apart, then swap a mob near one with a mob near another. Then you'd only need to deal with loaded chunks.

 

Also: Chunks without players tend to despawn their monsters, leaving only passive mobs. If you want more mayhem, then you want to work close to your players anyway.
