[1.11] How to add custom arrows for vanilla bow?

[CBUltimate]

The vanilla bow checks for ItemArrow but how can I make the vanilla bow check for ItemDullArrow?

[larsgerrits]

The

ItemBow

is using

instanceof

checks, meaning that if you make your arrow extend

ItemArrow

, it should work fine.

[CBUltimate]

But then the arrows shot out are normal arrow entities. How should I fix that?

[Kokkie]

What should be different?

[CBUltimate]

The custom arrows called Dull Arrows should be shot out.

[Kokkie]

Do you have a custom entity?

[CBUltimate]

I came across this error, what should I do? "Don't know how to add class mod.cbultimate.stranded.entity.EntityDullArrow"

It crashes when I try to start it.

 

EntityRegistry.registerModEntity(new ResourceLocation(StrandedMod.MODID, "dull_arrow"), EntityDullArrow.class, "entity_dull_arrow", 1, StrandedMod.class,1, 1, false);

 

Where should I register the entity? I tried to register it in FMLPreInitializationEvent.

[larsgerrits]

It crashes. There's no crash report supplied to us. No help can be given to you.

You have to use your

@Mod.Instance

variable instead of passing

StrandedMod.class

to

EntityRegistry#registerModEntity

.

[CBUltimate]

Is this what you mean?

 

EntityRegistry.registerModEntity(new ResourceLocation(StrandedMod.MODID, "dull_arrow"), EntityDullArrow.class, "entity_dull_arrow", 1, "mod.cbultimate.stranded.StrandedMod",1, 1, false);

 

 

[larsgerrits]

No, your

@Mod.Instance

variable you have in your

@Mod

class... You do have one right? It is a simple variable of your main mod class, with

@Mod.Instance

it, much like how

@SidedProxy

works.

My arrow entity is a white box, how do I fix that?

How do I use the resource location of vanilla Minecraft arrows?

 

EntityRegistry.registerModEntity(new ResourceLocation(StrandedMod.MODID, "dull_arrow"), EntityDullArrow.class, "entity_dull_arrow", 1, StrandedMod.instance,16, 1, false);

 

[CBUltimate]

What should I put for IRenderFactory?

[Animefan8888]

What should I put for IRenderFactory?

new IRenderFactory

[CBUltimate]

I'm trying to make the Renderer for the custom arrow but it gets quite complicated with RenderManager. How do I just use Minecraft's Vanilla Arrow Renderer?

 

        RenderingRegistry.registerEntityRenderingHandler(EntityDullArrow.class, new RenderDullArrow()); // RenderDullArrow() requires RenderManager

 

package mod.cbultimate.stranded.entity;

import net.minecraft.client.renderer.entity.RenderArrow;
import net.minecraft.client.renderer.entity.RenderManager;
import net.minecraft.util.ResourceLocation;
import net.minecraftforge.fml.relauncher.Side;
import net.minecraftforge.fml.relauncher.SideOnly;

@SideOnly(Side.CLIENT)
public class RenderDullArrow extends RenderArrow<EntityDullArrow>
{
    public static final ResourceLocation RES_ARROW = new ResourceLocation("textures/entity/projectiles/arrow.png");

    public RenderDullArrow(RenderManager renderManagerIn) {
        super(renderManagerIn);
    }

    /**
     * Returns the location of an entity's texture. Doesn't seem to be called unless you call Render.bindEntityTexture.
     */
    protected ResourceLocation getEntityTexture(EntityDullArrow entity)
    {
        return RES_ARROW;
    }
}
