Hello! I have been working on a mod and one of the main things currently is my bullet entity.

It renders in-game and works but I cannot get the hitbox right.

Currently, I am using this:

 setSize(0.1F, 0.1F);

to set the bounding box size. However, it renders this box below the entity in game:

As you can see the bullet(Yelllow square) is in the air and the bounding box is below it. Another small issue is that my bullet can be pushed and hurt. Any way to disable this?

RenderBullet.class & EntityBullet.class 

package codes.matthewp.nerdwarcraft.client;

import codes.matthewp.nerdwarcraft.entity.EntityBullet;
import net.minecraft.client.model.ModelZombie;
import net.minecraft.client.renderer.entity.Render;
import net.minecraft.client.renderer.entity.RenderLiving;
import net.minecraft.client.renderer.entity.RenderManager;
import net.minecraft.util.ResourceLocation;
import net.minecraftforge.fml.client.registry.IRenderFactory;

import javax.annotation.Nonnull;

public class RenderBullet extends RenderLiving<EntityBullet> {

    public static ResourceLocation mobTexture = new ResourceLocation("warcraft:textures/entity/bullet.png");


    public static final Factory FACTORY = new Factory();

    public RenderBullet(RenderManager renderManager) {
        super(renderManager, new ModelBullet(), 0.f);
    }

    @Override
    @Nonnull
    protected ResourceLocation getEntityTexture(@Nonnull EntityBullet entity) {
        return mobTexture;
    }

    public static class Factory implements IRenderFactory<EntityBullet> {
        @Override
        public Render<? super EntityBullet> createRenderFor(RenderManager manager) {
            return new RenderBullet(manager);
        }

    }
}

package codes.matthewp.nerdwarcraft.entity;

import net.minecraft.entity.EntityLiving;
import net.minecraft.util.math.AxisAlignedBB;
import net.minecraft.world.World;

public class EntityBullet extends EntityLiving {

    public EntityBullet(World worldIn) {
        super(worldIn);
        setSize(0.1F, 0.1F);
    }

    public void entityInit() {
        super.entityInit();
    }

}

EDIT: Added ModelBullet.class

@SideOnly(Side.CLIENT)
public class ModelBullet extends ModelBase {

    public ModelRenderer bulletBody;

    public int textureWidth = 16;
    public int textureHeight = 16;


    public ModelBullet() {
        bulletBody = new ModelRenderer(this, 0, 0);
        bulletBody.addBox(0, 0, 0, 2, 1, 4);
        bulletBody.setTextureSize(textureWidth, textureHeight);
    }

    @Override
    public void render(Entity entityIn, float limbSwing, float limbSwingAmount, float ageInTicks, float netHeadYaw, float headPitch, float scale) {
        renderBullet((EntityBullet) entityIn, limbSwing, limbSwingAmount, ageInTicks, netHeadYaw, headPitch, scale);
    }

    private void renderBullet(EntityBullet parEnntity, float limbSwing, float limbSwingAmount, float ageInTicks, float netHeadYaw, float headPitch, float scale) {
        bulletBody.render(0.01F);
    }
}

Wrong code

Bump! Still have not figured it out!

Why does your bullet extends EntityLiving (unless you meant to do this)?

If your entity should not behave like animals or mobs, then it should not extends EntityLiving.

You should just extend Entity instead.

Ah, forgot I left that there. I have switched it over, however now I don't know where to use my ModelBullet.class. It simply renders a small hitbox with no bullet. Any clue on the hitbox issue as well?

Modded projectiles should extend EntityArrow if they want synced movement accuracy. This is due to many class based (instanceof ArrowEntity) checks in vanilla that deal with packets and motion.

Switched. Still can't figure out how to get the bullet to render now, and even still, the hitbox issue.

 

Edit. Also, how can I apply the force bit? entity.addVelocity requires x,y,z not just simply movement forward

Use trigonometry to find the xyz values

What x,y,z values would I be trying to find?

The ones to pass into Entity#addVelocity. Look at ArrowEntity#shoot for vanilla's code
