Hello, I have a mod with some custom effects. I am trying to make if player has X custom effect player can't crouch. 

Here's my code for this :

@SubscribeEvent
    public static void onPlayerTick(TickEvent.PlayerTickEvent event) {

        if(event.phase != TickEvent.Phase.START || !event.player.isAlive()) {
            return;
        }

        final boolean lazyLeg = event.player.hasEffect(ModEffects.LAZY_LEGS.get());
        final Pose forcedPose = event.player.getForcedPose();

        if (lazyLeg && forcedPose != Pose.STANDING) {
            event.player.setForcedPose(Pose.STANDING);
            event.player.setPose(Pose.STANDING);
        } else if (!lazyLeg && Pose.STANDING == forcedPose) {
            event.player.setForcedPose(null);
        }

    }

If I switch Pose.STANDING's to Pose.FALL_FLYING the code is working but it is not working on STANDING pose. I couldn't understand why it is happening.

By the way I copied this code from here (https://github.com/skyjay1/GreekFantasy/blob/master-1.18/src/main/java/greekfantasy/GFEvents.java) and refactored it a little bit for my use.

Any help?

Hello, I am trying to cancel the crouch if player has an custom effect. I tried some methods but none of them have worked for me.

Here's my current code:

@SubscribeEvent
    public static void onKeyInput(InputEvent.Key event) {
        if (Minecraft.getInstance().screen != null) return;
        if (event.getKey() == 340) {

            Player pPlayer = Minecraft.getInstance().player;
            if (pPlayer.hasEffect(ModEffects.LAZY_LEGS.get())) {
                if (event.isCancelable()) {
                    event.setCanceled(true);
                }
//                event.setCanceled(true);
//                pPlayer.setPose(Pose.STANDING);
            }
        }
    }

    @SubscribeEvent
    public static void onPlayerTick(TickEvent.PlayerTickEvent event) {

        if(event.phase != TickEvent.Phase.START || !event.player.isAlive()) {
            return;
        }

        final boolean lazyLeg = event.player.hasEffect(ModEffects.LAZY_LEGS.get());
        final Pose forcedPose = event.player.getForcedPose();

        if (lazyLeg && forcedPose != Pose.FALL_FLYING) {
            event.player.setForcedPose(Pose.FALL_FLYING);
            event.player.setPose(Pose.FALL_FLYING);
        } else if (!lazyLeg && Pose.FALL_FLYING == forcedPose) {
            event.player.setForcedPose(null);
        }

    }

Nothing works here!

The crouching is not controlled by the player's Pose.

It is handled by the logic in LocalPlayer.aiStep() which is hardwired to check the isShiftKeyDown()

I guess you could hack something in the MovementInputUpdateEvent? But you can't just set shiftKeyDown = false,

because the isCrouching check is done before that event is fired.

 

I can't see a clean way do it other than using an access transformer to be able to change the LocalPlayer's isCrouching field?

Here's my current code:

I hope that the events are located in two different classes, since InputEvent.Key is a client side only Event and TickEvent.PlayerTickEvent is a client and server Event (common)

I decided to use AccessTransforms to do it but how I can change public methods code? How do I can override it?

 

Edit: I made AccessTransforms work. I can make fields public and change values but I couldn't understand how I can change a methods code?

LocalPlayer#crouching

It's is a field, you don't need to override any method (this is btw without using Mixin not possible),

you need to set LocalPlayer#crouching in MovementInputUpdateEvent to the value you want.

I changed it to a public field and this my code for now and it is not working

@SubscribeEvent
    public static void onPlayerTick(MovementInputUpdateEvent event) {
        if (event.getEntity() instanceof Player) {
            Player p = event.getEntity();
            Minecraft.getInstance().player.crouching = true;
        }
    }

You need to set it to false obviously. Also you will need to set forwardImpulse and leftImpulse on the KeyboardInput as KeyboardInput#tick is called before MovementInputUpdateEvent.

it is just making player can't crouch visually I can still crouch

Eyes are going down and player gets slower

        }
    }

}

• Use the player given to you in the event.

• You have not done this.

• You also need to set shiftKeyDown to false on the Input instance, as that is what will be sent to the server.

Ok I finally did it working. Everything works fine. Here's the last version of my codes:

accesstransformers.cfg : 

public net.minecraft.client.player.LocalPlayer f_108601_ # crouching

ModEvents.java :

package com.fantalatone.sculknightmare.event;

import com.fantalatone.sculknightmare.SculkNightmare;
import com.fantalatone.sculknightmare.effect.ModEffects;
import net.minecraft.client.Minecraft;
import net.minecraft.client.player.LocalPlayer;
import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.client.event.MovementInputUpdateEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;

@Mod.EventBusSubscriber(modid = SculkNightmare.MODID, bus = Mod.EventBusSubscriber.Bus.FORGE, value = Dist.CLIENT)
public class ModEvents {

    @SubscribeEvent
    public static void onPlayerTick(MovementInputUpdateEvent event) {
        LocalPlayer pPlayer = Minecraft.getInstance().player;
        if (pPlayer.hasEffect(ModEffects.LAZY_LEGS.get())) {
            event.getInput().shiftKeyDown = false;
            pPlayer.crouching = false;
        }
    }
}

 

Thanks for everybody helped me!
