                            	if ((movingobjectposition.entityHit instanceof EntityEnderman))
                            	{ignorar = true;}
                            	
                            	if ((movingobjectposition.entityHit instanceof EntityMinecartChest))
                            	{ignorar = true;}

                            	if ((movingobjectposition.entityHit instanceof EntityMinecartContainer))
                            	{ignorar = true;}
                            	
                            	if ((movingobjectposition.entityHit instanceof EntityMinecartEmpty))
                            	{ignorar = true;}

                            	{ignorar = true;}
                            	
                            	if ((movingobjectposition.entityHit instanceof EntityMinecartHopper))
                            	{ignorar = true;}
                            	
                            	if ((movingobjectposition.entityHit instanceof EntityBoat))
                            	{ignorar = true;}
                            	
                            	
                            	if (!ignorar)
                                {
                                  EntityLivingBase mob =(EntityLivingBase) movingobjectposition.entityHit;
                          	      mob.setHealth(mob.getHealth()-5);
                                }

I did something like this before, I really don't remember everything, but I remember, you need to create new arrow handler and when it hit, you need to give a poison potion to victim

Few facts:

1. You can't do this:

EntityLivingBase mob =(EntityLivingBase) movingobjectposition.entityHit;

Without first checking if that movingobjectposition is Living.

if (movingobjectposition.entityHit instanceof EntityLivingBase)
{
((EntityLivingBase) movingobjectposition).doStuff();
}

2. That is NOT how you deal damage, mionecraft has DamageSources for a reason, it even has alredy made armour piercing sources and poison.

entityLiving.attackEntityFrom(DamageSource.XXX, float);

Look at DamageSources - you can use e.g DamageSource.starve to deal absolute damage, but that is not way to go, since if you die it will display you died of hunger. You can make your own DamagSource which will .setDamageIsAbsolute(); or .setDamageBypassesArmor()

3. To add poison you will need: (example)

entityLiving.addPotionEffect(new PotionEffect(Potion.poison.id, 50));

1.7.10 is no longer supported by forge, you are on your own.

How to change player renderer and transform model parts?

I have been trying for a while now to make a custom player renderer, and replace the vanilla player renderer with it. So far I've come up with a custom player renderer class that extends vanilla PlayerRenderer:
package com.FireDude123.BOTW.entity.renderer; import com.mojang.blaze3d.vertex.PoseStack; import net.minecraft.client.player.AbstractClientPlayer; import net.minecraft.client.renderer.MultiBufferSource; import net.minecraft.client.renderer.entity.player.PlayerRenderer; import net.minecraft.client.renderer.entity.EntityRendererProvider; import net.minecraftforge.client.event.RenderPlayerEvent; import net.minecraftforge.common.MinecraftForge; public class PoseablePlayerRenderer extends PlayerRenderer { public PoseablePlayerRenderer(EntityRendererProvider.Context ctx, boolean slim) { super(ctx, slim); System.out.println("here too"); } @Override public void render(AbstractClientPlayer p_117788_, float p_117789_, float p_117790_, PoseStack poseStack, MultiBufferSource p_117792_, int p_117793_) { System.out.println("didnt get here lol"); model.leftArm.xRot=(float)Math.toRadians(160); super.render(p_117788_, p_117789_, p_117790_, poseStack, p_117792_, p_117793_); } } As you can see, the intended purpose of this is to raise the player's left arm by 160 degrees. However, combined with this logic in ClientModEvents:
@Mod.EventBusSubscriber(modid = MODID, bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT) public static class ClientModEvents { @SubscribeEvent public static void onClientSetup(FMLClientSetupEvent event) { EntityRenderers.register((EntityType<? extends AbstractClientPlayer>)(EntityType<?)EntityType.PLAYER, ctx -> new PoseablePlayerRenderer(ctx, true)); EntityRenderers.register(Entities.MAGNESIS_BLOCK.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.REMOTE_BOMB.get(), ThrownItemRenderer::new); EntityRenderers.register(Entities.CRYONIS_ICE.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.STASIS_BLOCK.get(), FallingBlockRenderer::new); } @SubscribeEvent public static void registerLayerDefinitions(EntityRenderersEvent.RegisterLayerDefinitions event) { event.registerLayerDefinition(new ModelLayerLocation(new ResourceLocation(BOTW.MODID, "paraglider"), "main"), ParagliderLayer::createBodyLayer); } }(I also have a paraglider layer here for something else, it's working perfectly fine, also I used the slim setting because the player is slim in 1.20.1 forge)
This logic isn't replacing the renderer, as far as I can tell. Can someone please advise as to why, and how to fix it?

How to add my mob to another mod's biome in 1.20.1.

I'm on 1.20.1 and was wondering if there was a way to add a mob I am going to make to a other mod's biome (Regions Unexplored in this case). I am trying to figure this out before I start coding the mod. Could someone point me to a good guide on this? I saw some things about biome modifier's but all the resources are either to short, unhelpful or for a different version. Thanks in advance. (i am a beginner but i have java and modding knowledge so this isn't like a "i am new and don't know anything about coding" problem btw)

Dealing with modded server issues can be a real headache been there! At least you can keep your look stress-free with a fresh low taper fade.

Help with file conversion

Many Forge users seek help with file conversions. Similarly, managing your health can benefit from structured tools like the https://wellness-app.com/calculator/fasting-calculator/ and a free intermittent fasting calculator. These tools help you plan and personalize your fasting and eating windows based on your lifestyle and goals. By entering your preferred fasting duration and meal times, you receive a tailored schedule that makes intermittent fasting easier to follow. Just as mastering file conversions improves modding success, using a fasting calculator brings clarity and structure to your health routine, supporting better results over time.

Cobblemon invalid player data

Hi everyone, I keep getting "invalid player data" when trying to log onto my friend's server. Log analysis says to remove Night Lights and ImmediatelyFast, but that doesn't work. Any insight is appreciated
