This line of code doesn't change the state variable you have. It changes the state in the world. So your println should look like this.
worldIn.getBlockState(pos).get(READY);

Well hell with the prinln(), what should I do instead to change the variable state.

state = state.with...

However that only changes the memory address of that variable it doesn't change anything else. BlockStates are singletons just like Blocks.

Oh.. Well I did the new println() you gave me and it still shows false....

I can't replicate your issue on my own block.

	@Override
	public void tick(BlockState state, World worldIn, BlockPos pos, Random random) {
		System.out.println(worldIn.getBlockState(pos).get(BlockStateProperties.HORIZONTAL_FACING));
		worldIn.setBlockState(pos, state.cycle(BlockStateProperties.HORIZONTAL_FACING));
		System.out.println(worldIn.getBlockState(pos).get(BlockStateProperties.HORIZONTAL_FACING));
	}

It prints as expected. I am unsure as to why it isn't working for you.

Odd.... When I have this line :  worldIn.setBlockState(pos, state.with(READY, 'value'), 3); in my onBlockAdded method, I can change the variable to true or false, as confirmed by println(). It just won't change inside of tick method. My original println() actually works fine by the way.

It should not work. And if it does there is something very very wrong.

Which doesn't any sense what so ever. And thus maybe a new world or new forge setup is needed.

Actually Houston, I found the answer. I was able to get the variable to change in tick method, the problem is the onBlockAdded is called multiple times, four times or more I counted, so it resets the variable back to what I had it set to in there. I guess the solution is to not have it set in there, and just deal with it being true by default, easy adjustment. I'll call it UNREADY instead of READY. But anyways is multiple calls to that method with only one block created normal?

You can change that by calling setDefaultState in your constructor. IE
setDefaultState(getDefaultState().with(...))

two player hands. 2x2

This is wrong. It's called 4 times because it is executed in two separate places when a block(Chunk#setBlockState and ForgeHooks.onPlaceItemIntoWorld) is placed then we have both sides. Which comes out to be 4.

Where is the 2 hands thing from?

I'm not sure maybe onBlockActivated or from an older version.

How does it come out to 4 if it's two sides... maybe i shouldn't ask. Well that means tick() will be called 4 times as, worldIn.getPendingBlockTicks().scheduleTick(pos, this, 360, TickPriority.HIGH); is in that method, but this shouldn't affect anything.

Whoops forgot all about that, I was so focused on that method.

It's called on both sides from each of those methods I posted. That execute at "the same time".

Oh gotcha.

Huh. Have I got this mixed up? Where is the 2 hands thing from?

rightClick and related methods that have a hand parameter. Its still relevant, just maybe not for this situation.

New Q. How could I make custom flags for drops? For example, pigs and other animals drop cooked rather than raw meat if they die while on fire, which is done by a flag check for "is_on_fire". I want to do something similar, so my block only drops something when a certain condition is met. 

Implement (and register) your own ILootCondition

I see the implementation examples in vanilla files, but I don't understand how to register. The docs say to use this method : LootConditionManager.registerCondition(), but it takes an instance of a class that cannot be instantiated.

Hint: Inheritance. Vanilla has to do it somehow.

Oh I see now. 

So I done diddly did this :

 

Spoiler

package mymod;

import javax.annotation.Nullable;

import com.google.gson.JsonDeserializationContext;
import com.google.gson.JsonObject;
import com.google.gson.JsonSerializationContext;

import net.minecraft.util.JSONUtils;
import net.minecraft.util.ResourceLocation;
import net.minecraft.world.storage.loot.LootContext;
import net.minecraft.world.storage.loot.conditions.ILootCondition;

public class Ready implements ILootCondition {
	
	private final Boolean hot;
	
	private Ready(@Nullable Boolean hot) {
		
	    this.hot = hot;
    }
	
	public static class Serializer extends ILootCondition.AbstractSerializer<Ready> {
	
	    public Serializer() {
	    		
	        super(new ResourceLocation("Ready"), Ready.class);
	    }

	    public void serialize(JsonObject json, Ready value, JsonSerializationContext context) {

	    	json.addProperty("hot", value.hot);
	    }

	    public Ready deserialize(JsonObject json, JsonDeserializationContext context) {
	    	
	    	Boolean obool = json.has("hot") ? JSONUtils.getBoolean(json, "hot") : null;
	        return new Ready(obool);
	    }
	}

	@Override
	public boolean test(LootContext t) {
		
		return false;
	} 

}

 

And this in my main mod class : LootConditionManager.registerCondition(new Ready.Serializer());

 

So now how do I actually use it so that the boolean here changes when I need it to from my block class?

Not having messed with Loot Conditions, I recommend you examine the existing loot condition classes and how they're used.

Well for example there is the Is_On_Fire flag for entities, where is the class that shows how this is used?
