WorldSavedData, write and saveNBT data?

[tebreca]

Hello,

I want to create seasons, but i dont really understand the Inheritance of the classes,

I need to use Write and Read to NBT methods,

 

but i dont understand how the information gets called in my class and how to write stuff to nbt if i dont get any parameters for what to write.

i would like some help here,

 

my seasons class:

package btf.objects.worldDataSaving;

import btf.main.Vars;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.world.storage.WorldSavedData;

public class Seasons extends WorldSavedData {
	 private static final String DATA_NAME = Vars.MOD_ID + "_ExampleData";

	  // Required constructors
	  public Seasons() {
	    super(DATA_NAME);
	  }
	  public Seasons(String s) {
	    super(s);
	  }

	@Override
	public void readFromNBT(NBTTagCompound nbt) {
			
	}
	
	@Override
	public NBTTagCompound writeToNBT(NBTTagCompound compound) {
		
		return null;
	}
}

 

the eventhandler for the ticking and registering days:

@EventBusSubscriber
public class EventHandler {
	int i = 0;
	MapStorage storage = null;
public void onworldTick(WorldTickEvent event) {
	World tickingWorld = event.world;
		if (storage == null) {
				storage = tickingWorld.getMapStorage();
		}else {
			if (i >= 24000) {
				i=0;
				WorldSavedData data = storage.getOrLoadData(Seasons.class, "CurrentSeason");
				
		}else {
				i++;
		}
		}	
	}
	public void atsleep(PlayerSleepInBedEvent event) {
		World tickingWorld = event.getEntityPlayer().getEntityWorld();
		if (storage == null) {
			storage = tickingWorld.getMapStorage();
		}
			//writenextday
	}
}

• You cannot just stuff a tick counter in your event handler class. The server has multiple worlds (dimensions), the event will fire for all of them.
• WorldTickEvent has a phase, you probably do not want to execute your code in both.
• What on earth is that MapStorage field supposed to do?
• You must store the data you want to store in your WorldSavedData class, it is the holder for the data. You should read the documentation.

thx for the help,

i already tought about doing something with the ITickable interface, is that better for doing the ticks?

 

i have read the docs but i didnt understand, now i've read it again and i understand it now,

maybe it was allitle bit too late yesterday.

 

should i make a new post or just ask here if i need to use a ITickable to make the worldstoreddata tick?

ok, but i meant: How can i register days, like what is the most efficient way of getting when a new day starts so i can register it in my map data? and so i can calculate the current season and the stage of the season.

Because i wanna override the grasscolors, flower colors and leave colors  on client side depending on the season.
