SetPose implementation

[Naxehr]

I'm trying to make a mod where it uses a key binding to crawl and hold onto monkey bars and stuff like that, but I'm getting stuck on changing Steves "pose". I found a setPose() function but i cant figure out how to implement it in my code

package com.naxehr.parkourmod.events;

import com.naxehr.parkourmod.ParkourMod;
import com.naxehr.parkourmod.init.iteminit;
import com.naxehr.parkourmod.util.helpers.KeyBindings;

import net.minecraft.entity.Pose;
import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.inventory.EquipmentSlotType;
import net.minecraftforge.client.event.InputEvent.KeyInputEvent;
import net.minecraftforge.client.event.RenderPlayerEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.Mod.EventBusSubscriber.Bus;

@Mod.EventBusSubscriber(modid = ParkourMod.MOD_ID, bus = Bus.FORGE)

public class KeyInputHandler {
	PlayerEntity player;
	public void OnRenderPlayerPre(RenderPlayerEvent.Pre event) {
		player = (PlayerEntity) event.getEntity();
	}
	@SubscribeEvent
	public void onKeyInput(KeyInputEvent event) {
		if (KeyBindings.crawl.isPressed()) {
			if (player.getItemStackFromSlot(EquipmentSlotType.LEGS).getItem() == iteminit.parkour_knee_guard) {
				player.setPose(Pose.SWIMMING);
			}
		}
		if (KeyBindings.hold.isPressed()) {
			if (player.getItemStackFromSlot(EquipmentSlotType.CHEST).getItem() == iteminit.parkour_gloves) {
				player.setPose(Pose.SWIMMING);
			}
		}
	}
}//end of my code

//Setpose command i found in Minecrafts Entity.class

   protected void setPose(Pose p_213301_1_) {
      this.dataManager.set(POSE, p_213301_1_);
   }

   public Pose getPose() {
      return this.dataManager.get(POSE);
   }

//seperate code in Enity.class that initializes datamanager
   public Entity(EntityType<?> entityTypeIn, World worldIn) {
      super(Entity.class);
      this.type = entityTypeIn;
      this.world = worldIn;
      this.size = entityTypeIn.getSize();
      this.setPosition(0.0D, 0.0D, 0.0D);
      if (worldIn != null) {
         this.dimension = worldIn.dimension.getType();
      }

      this.dataManager = new EntityDataManager(this);
      this.dataManager.register(FLAGS, (byte)0);
      this.dataManager.register(AIR, this.getMaxAir());
      this.dataManager.register(CUSTOM_NAME_VISIBLE, false);
      this.dataManager.register(CUSTOM_NAME, Optional.empty());
      this.dataManager.register(SILENT, false);
      this.dataManager.register(NO_GRAVITY, false);
      this.dataManager.register(POSE, Pose.STANDING);
      this.registerData();
      this.eyeHeight = getEyeHeightForge(Pose.STANDING, this.size);
      net.minecraftforge.common.MinecraftForge.EVENT_BUS.post(new net.minecraftforge.event.entity.EntityEvent.EntityConstructing(this));
      this.gatherCapabilities();
   }

//setpose command i found in Minecrafts PlayerEntity.class
   @OnlyIn(Dist.CLIENT)
   public void preparePlayerToSpawn() {
      this.setPose(Pose.STANDING);
      super.preparePlayerToSpawn();
      this.setHealth(this.getMaxHealth());
      this.deathTime = 0;
   }

You have set the player's pose at the end of every tick, because minecraft updates the player pose every tick. You will probably also need to do some extra work to support custom poses.

Check out my mod GoProne (github). If you copy/paste stuff from it please make sure you credit me.

I'm not even getting my code to run. i see its protected, which makes sense why its giving me an error when i try to call the setpose function.

Quote

The method setPose(Pose) from the type Entity is not visible

when i try to call it directly from the other script.

		if (KeyBindings.crawl.isPressed()) {
			if (player.getItemStackFromSlot(EquipmentSlotType.LEGS).getItem() == iteminit.parkour_knee_guard) {
				net.minecraft.entity.player.PlayerEntity.setPose(Pose.SWIMMING);
			}
		}

What other script?

Did you look at my code?

You need to use Reflection, or an access transformer to set the pose.

You need to set the pose on the server (you need to send a packet when the button is pressed/released).

Which means you need to keep track of which players should be prone, and set the pose of each of them in a PlayerTickEvent.

if you see my line of code you referenced,
net.minecraft.entity.player.PlayerEntity.setPose(Pose.SWIMMING);
i reference the PlayerEntity script to try to setPose, that's what i was referring to. Also i haven't looked at your code yet because github has problems with my work internet, but I'm planning on viewing it, thanks so much btw.

And thanks for pointing me in the right direction, that should help a lot!
