I am trying to add a few custom arrows for a project i'm currently working on.

I have the classes all there and setup however there are some errors on a couple of constructors (see below)

import net.minecraft.world.entity.EntityType;
import net.minecraft.world.entity.LivingEntity;
import net.minecraft.world.entity.projectile.AbstractArrow;
import net.minecraft.world.entity.projectile.Arrow;
import net.minecraft.world.item.ItemStack;
import net.minecraft.world.level.Level;
import net.minecraft.world.phys.EntityHitResult;
import org.multicoder.mcpaintball.init.entityinit;

public class RedPaintballArrowEntity extends Arrow
{

    public RedPaintballArrowEntity(EntityType<? extends RedPaintballArrowEntity> p_36858_, Level p_36859_) {
        super(p_36858_, p_36859_);
    }

    public RedPaintballArrowEntity(Level p_36861_, double p_36862_, double p_36863_, double p_36864_) {
        super(entityinit.RED_PAINTBALL.get(),p_36861_, p_36862_, p_36863_, p_36864_);
    }

    public RedPaintballArrowEntity(Level p_36866_, LivingEntity p_36867_) {
        super(entityinit.RED_PAINTBALL.get(), p_36866_, p_36867_);
    }

    @Override
    protected ItemStack getPickupItem()
    {
        return ItemStack.EMPTY;
    }

    @Override
    protected void onHitEntity(EntityHitResult p_36757_)
    {

    }
}

The error is with the bottom 2 constructors and it is saying cannot resolve method 'super', I am completely stuck on what to do or why this is happening to begin with. Am I missing something.

import net.minecraft.world.entity.EntityType;
import net.minecraft.world.entity.MobCategory;
import net.minecraftforge.registries.DeferredRegister;
import net.minecraftforge.registries.ForgeRegistries;
import net.minecraftforge.registries.RegistryObject;
import org.multicoder.mcpaintball.MCPaintball;
import org.multicoder.mcpaintball.entity.RedPaintballArrowEntity;

public class entityinit
{
    public static final DeferredRegister<EntityType<?>> ENTITY_TYPES = DeferredRegister.create(ForgeRegistries.ENTITIES, MCPaintball.MODID);

    public static final RegistryObject<EntityType<RedPaintballArrowEntity>> RED_PAINTBALL = ENTITY_TYPES.register("red_paintball",() -> EntityType.Builder.of(RedPaintballArrowEntity::new, MobCategory.MISC).sized(0.5f,0.5f).build("red_paintball"));
}

This is my entitytype register.

As the compiler is telling you, those constructors don't exist.

They do exist on AbstractArrow, but you aren't extending that class.

Please don't post basic java questions in this forum. Buy a book or whatever you need to learn the language.

Right I was not aware of the abstract arrow was what had both constructors. I thought that both abstract arrow and arrow has both constructors
