I wish to create a forge mod for 1.15.2 which drains the hunger bar in peaceful. I know you can do /gamerule doMobSpawning false but that doesn't stop spawners. In the minecraft code there is a file called FoodStats.java which contains the game logic for hunger. 

How can I change it so that the hunger goes down in peaceful?

Please do not post Minecraft code, we can all look at it in our IDE.

Sorry about that.

You can use PlayerTickEvent (make sure to check TickEvent#phase) and change the food level that way.

How would I do that?

Which part?

Using PlayerTickEvent and changing the food level that way.

 

Sorry I am a bit of a beginner.

As for how to change the food level, you do the same thing that the code you already found does.

I don't understand how to do that.

You don't know how to copy-paste code?

that didn't work. which event should i use for the event handler?

PlayerTickEvent. Make sure you are executing the hunger changing code on the server side (read up on Sides in the documentation if you are unsure).

I read the documentation however I do not understand how to make my event work on the server side only. When I use

DistExecuter.runWhenOn

runWhenOn cannot be resolved. How could I make my code into server side only?

Proxies are not necessary in this case.

The event provide you with an instance of World; use World#isRemote (which returns true on client and false on server) to check what side you are on.

How would I make my code 

@SubscribeEvent
    public void hunger(TickEvent.PlayerTickEvent event) {
        PlayerEntity player = null;
        Difficulty difficulty = player.world.getDifficulty();
        this.prevFoodLevel = this.foodLevel;
        if (this.foodExhaustionLevel > 4.0F) {
            this.foodExhaustionLevel -= 4.0F;
            if (this.foodSaturationLevel > 0.0F) {
                this.foodSaturationLevel = Math.max(this.foodSaturationLevel - 1.0F, 0.0F);
            } else if (difficulty != Difficulty.PEACEFUL) {
                this.foodLevel = (int) Math.max(this.foodLevel - 1.0f, 0.0f);
            }
        }
    }

use world#isRemote?

                this.foodLevel = (int) Math.max(this.foodLevel - 1.0f, 0.0f);
            }
        }
    }

use world#isRemote?

 

Use an if statement, 

if(event.player.world.isRemote()) {
  //Insert code here
}

if you don't know how to change the player's hunger level try something like:

event.player.getFoodStats().addStats(0, 0.0f);

I am getting this error. Cannot resolve symbol event and the word event turns red. How do I fix this?

Do you know anything about Java? The code should look like this:

            public void hunger(TickEvent.PlayerTickEvent event) {
              if(event.player.world.isRemote())
              {
                PlayerEntity player = event.player;
                Difficulty difficulty = player.world.getDifficulty();
                this.prevFoodLevel = this.foodLevel;
                if (this.foodExhaustionLevel > 4.0F) {
                    this.foodExhaustionLevel -= 4.0F;
                    if (this.foodSaturationLevel > 0.0F) {
                        this.foodSaturationLevel = Math.max(this.foodSaturationLevel - 1.0F, 0.0F);
                    } else if (difficulty != Difficulty.PEACEFUL) {
                        this.foodLevel = (int) Math.max(this.foodLevel - 1.0f, 0.0f);
                    }
                }
              }
            }

Anyway, learn Java basics before modding.

Dieseben made a nice comment.

you need invert the remote check. now you are running on the client you need the server

Someone please tell me the OP has been spending the last eight months learning Java? 

 

Also, side note; if you would like to add another type of survival data, like "Insanity", which drains the longer you spend in low light levels, you could use compatibilities to create the data and assign it to the players. 

Wait guys, I still don't don't understand... I shall send my code

-- Define the function to decrease hunger
local function decreaseHunger(player)
    local currentHunger = player.getHunger()
    
    -- Check if hunger is not already zero
    if currentHunger > 0 then
        player.setHunger(currentHunger - 1)
    end
end

-- Register event to decrease hunger over time
script.registerEvent(EntityPlayer, function(player)
    while true do
        -- Decrease hunger every few seconds
        decreaseHunger(player)
        script.sleep(1000) -- Sleep for 1 second
    end
end)
 

 

Any help appriecated.

It's been a while since I learnt Javascript or whatever Minecraft is made with... ... ...
