[RESOLVED][1.7.10] Force the unloading of a dimension

[Nereidregulus]

Hi everybody!

I'm trying to make a new mod for 1.7.10, but I have a problem:

For my mod, I want to create a maze in a dimension, and at the end of the maze a block teleport you into the next floor of the maze. Actually I want to make one floor per dimension(similar to mystery dungeon series). I think I will create two dimension, and when the player leave the first one, he gets teleported into the second and the first dimension regenerate. If he leave the second one, he will teleport to the first and the second will regenerate until he found the exit.

 

I've alredy created my dimension, the maze, the dimension regenerate but here is my problem: it seems like if the dimension is loaded, it cannot be deleted(logical), but i don't know how to force this unloading. I've try DimensionManager.setWorld(id,null); but it doesn't work... I also notice that sometimes the unloading is very long to operate ( I assume that the unloading is ongoing if the message "Unloading dimension x" is on the console).

 

Please help me!

Why force unload it? If you're on a server, and the dimension is unloaded when one person leaves and one is still in it; the player still in it would die. ALL dimensions are loaded when the game/server is started and unloaded when the server is stopped. There is really no need to unload the dimension just, send them to the new one.

Actually, I want the dimension to be recreated, and so i have to delete it and to unload it. Is there any way to call a function to unload a dimension? Moreover, I won't delete a dimension if a player is inside, but for now i will make this mod work for one player.

 

I were thinking of adding a third dimension, so the first dimension will be deleted when the player leave the second to go to the third.

 

I also know that dimension can be deleted because sometimes when i came back into the first one, it have been regenerated.

I don't have exact answer, but two hints/ideas.

You could look into multiverse or multiworld repo for help.

You could track down vanilla unloading code.

If I were you I would start from world unload event.

Thank you, I've finally succeed to do it with a tickhandler, but i still have to wait the unloading of a dimension...

Considering you want to delete and regenerate the dimension. I believe the actually world data would have to be deleted and re-created. Unloading a dimension saves it to it's current state I believe.

[Nereidregulus]

Yes but the world can't be deleted if it is loaded.

Also, I have a problem on the world unload event, it seems that i can't make it work properly.

package com.MysteryDungeon.Main;

import java.io.File;

import net.minecraft.world.World;
import net.minecraft.world.WorldProvider;
import net.minecraft.world.WorldServer;
import net.minecraftforge.common.DimensionManager;
import net.minecraftforge.common.ForgeChunkManager;
import net.minecraftforge.common.util.FakePlayerFactory;
import net.minecraftforge.event.world.WorldEvent;
import cpw.mods.fml.common.FMLLog;
import cpw.mods.fml.common.eventhandler.EventPriority;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import cpw.mods.fml.common.gameevent.TickEvent;

public class DungeonEventHandler {

    @SubscribeEvent(priority = EventPriority.HIGHEST)
    public void onDimensionUnload(WorldEvent.Unload event)
    {
    	System.out.println("Top");
        //Rest of the code
    }
}

And when a dimension unload, or when i stop the game (all dimension should unload when i close the game), the "Top" doesn't appear on console.

Did I miss something or did I do something wrong?

Ok my mad, I have register the wrong type of event, I used

FMLCommonHandler.instance().bus().register(new DungeonEventHandler());

instead of

MinecraftForge.EVENT_BUS.register(new DungeonEventHandler());

 

Now the dimension is deleted when minecraft unload it, but I still can't do it by myself. Anyone here have a solution?

[Nereidregulus]

I fixed it!

I needed to add the following line:

DimensionManager.setWorld(dimensionId,null);
