I want to disable healing (from food, not from potions). I know you can do this by disabling the gamerule "naturalRegeneration" but if I'm correct, this will disable the healing for all players. Is there a way to disable the natural healing per player?

I'm wondering if it's possible to cancel the healing and NOT to check whether the player heals and then apply damage to them.

To disable generation from food (not from peaceful difficulty) you'd have to replace the Player's FoodStats object with your own version that does special handling.

Okay, I know how to make my own custom FoodStats using capabilities, but how can I disable/replace the original then?

Set PlayerEntity#foodStats using reflection.

When do I set it? Is there a PlayerEntity/Entity creation event or something similar that I should use? I only found EntityJoinWorldEvent but then it would create a new FoodStats object everytime the entity joins. How can I check if the entity hasn't been created before? Or should I use something completely different?

EntityJoinWorldEvent is exactly right. You have to set the object every time. It does not magically persist.

Thank you, I got it working that my custom FoodStats is set. I have one more problem:

I created a class named CustomFoodStats that extends FoodStats. When I try to override/copy the tick() method I get lots of errors because all the fields of FoodStats are not accessible. Should I also use reflection to get and set these fields or should I do something else (because that would require a lot of reflection every tick, which I believe is not something I should be doing)?

 

public class CustomFoodStats extends FoodStats {

    private boolean foodHealthRegen = true;

    public CustomFoodStats() {
        super();
    }

    @Override
    public void tick(PlayerEntity player) {
        /*
        this part would be copied from the original FoodStats (don't know if I could post that here)
        */

        boolean flag = player.world.getGameRules().getBoolean(GameRules.NATURAL_REGENERATION) && this.foodHealthRegen;
      
        /*
        this part would be copied from the original FoodStats (don't know if I could post that here)
        */
    }
}

 

Also I have an additional question. Because I want to override the tick() method but I only change boolean flag, would that not be allowed because in essence I would then almost be entirely copying a method from the minecraft code.

You can also use access transformers instead of reflection.

I didn't know that was a thing so thank you, that looks like it is exactly what I need. I tried to use it but I can't get it to work.

 

Here is my accesstransformer.cfg

# Makes the fields from the FoodStats class public
public net.minecraft.util.FoodStats foodLevel
public net.minecraft.util.FoodStats foodSaturationLevel
public net.minecraft.util.FoodStats foodExhaustionLevel
public net.minecraft.util.FoodStats foodTimer
public net.minecraft.util.FoodStats prevFoodLevel

 

And here the line I put into my build.gradle (in the minecraft section, under the line with the mappings)

accessTransformer = file('src/main/resources/META-INF/accesstransformer.cfg')

 

It says that then I should refresh and it should work, but I refreshed and the fields still don't show up. Do you know how I should fix this?

You need to provide it with the SRG names.

Where can I find these names?

Thank you for your help, now it works
