But I have some problem.

When I am at Cretive mode I can throw a spear and I see my spear in the fly.

But when I am at Game mode, when I throw a spear I get at once hit (4 hearts) and I not see my spear in the fly... I not understand this.

Maybe problem in onCollideWithPlayer or in other place?...

Thanks.

 

/sorry for my english/

this.setPosition(this.posX, this.posY+1, this.posZ);

SOLVED

 

Sorry, but I have another problem.

When I hit a spear in myself :-), then if look from the side, instead of spears - arrow.

 

In entity arrow and in Render I find nothing. But in RenderPlayer I find renderEquippedItems function that call another interesting function super.renderArrowsStuckInEntity (par1AbstractClientPlayer, par2)

I try override this.

                    double d2 = 0.0D;
                    float f8 = 0.0F;
                    this.renderManager.renderEntityWithPosYaw(entityarrow, d0, d1, d2, f8, par2);
                    GL11.glPopMatrix();
                }

                RenderHelper.enableStandardItemLighting();
            }
        
    }

}

 

 

But nothing.

Tell me where to look or how to make it.

Thanks.

Look at the event RenderPlayerEvent.Specials.Pre

 

This is fired in RenderPlay#renderEquippedItems - render all your spears in that event if there are any.

 

Also, look at RendererLivingEntity#RenderArrowsStuckInEntity(...) for ideas on how to render your spears in entity.

I found it before. But for me, too hard to do it.

I can only turn off render the spear

in Entity (Update method)

if (movingobjectposition.entityHit.attackEntityFrom(damagesource, (float)k))
                    {
                        if (movingobjectposition.entityHit instanceof EntityLivingBase)
                        {
                            EntityLivingBase entitylivingbase = (EntityLivingBase)movingobjectposition.entityHit;

                            if (!this.worldObj.isRemote)
                            {
                               // entitylivingbase.setArrowCountInEntity(entitylivingbase.getArrowCountInEntity() + 1);
                            }

                            if (this.knockbackStrength > 0)
                            {
                                f4 = MathHelper.sqrt_double(this.motionX * this.motionX + this.motionZ * this.motionZ);

                                if (f4 > 0.0F)
                                {
                                    movingobjectposition.entityHit.addVelocity(this.motionX * (double)this.knockbackStrength * 0.6000000238418579D / (double)f4, 0.1D, this.motionZ * (double)this.knockbackStrength * 0.6000000238418579D / (double)f4);
                                }
                            }

                            if (this.shootingEntity != null && this.shootingEntity instanceof EntityLivingBase)
                            {
                                EnchantmentHelper.func_151384_a(entitylivingbase, this.shootingEntity);
                                EnchantmentHelper.func_151385_b((EntityLivingBase)this.shootingEntity, entitylivingbase);
                            }

                            if (this.shootingEntity != null && movingobjectposition.entityHit != this.shootingEntity && movingobjectposition.entityHit instanceof EntityPlayer && this.shootingEntity instanceof EntityPlayerMP)
                            {
                                ((EntityPlayerMP)this.shootingEntity).playerNetServerHandler.sendPacket(new S2BPacketChangeGameState(6, 0.0F));
                            }
                        }

or through event RenderPlayerEvent.Specials.Pre

private EntityVyla bb;
private EntityArrow cc;

@SubscribeEvent 
public void onRenderPlayer(RenderPlayerEvent.Pre e)
{

	if (!e.entityPlayer.hitByEntity(bb))
		{
		e.entityPlayer.setArrowCountInEntity(0);

		}
  }

You did not read well,  I said RenderPlayerEvent.Specials.Pre , not the one you substituted.

 

Are you wanting to stop rendering the arrows? Because, that is not so easy. But why? Just render your spears and ignore the arrows.

    • Hello, Hi and I am making a forge 1.12.2 mod and also trying to get a custom model helmet item (I made a joker mask) and exported it to .json format and put it in the ~/namespace/models/item folder. Though, I'm struggling to get the item to render what I want it to be rendered like as I've positioned it in the 'head' window view in blockbench. How did you render out your model? I checked your code and it looks like no references to the actual model are being made. I'm new to this forge modding stuff (was a fabric modder) and I desperately need some help. Is there a way to standardly render out armor models made using blockbench? any methods that one can use? My model in JSON: ```json { "credit": "Made with Blockbench", "texture_size": [160, 160], "textures": { "0": "ydyrn:items/joker_mask_texture", "particle": "ydyrn:items/joker_mask_texture" }, "elements": [ { "from": [0, 0, 0], "to": [16, 16, 1], "faces": { "north": {"uv": [0, 1.7, 16, 14.2], "texture": "#0"}, "east": {"uv": [0, 4, 0.9, 5.6], "texture": "#0"}, "south": {"uv": [0, 5.8, 1.6, 7.4], "texture": "#0"}, "west": {"uv": [0, 1.9, 1.3, 3.5], "texture": "#0"}, "up": {"uv": [0, 3.4, 1.6, 4.2], "texture": "#0"}, "down": {"uv": [0, 9, 1.6, 9.7], "texture": "#0"} } }, { "from": [15.8, 11, 0.5], "to": [16.2, 13, 15], "faces": { "north": {"uv": [7.9, 7.9, 7.94, 8.1], "texture": "#0"}, "east": {"uv": [7.9, 7.9, 9.35, 8.1], "texture": "#0"}, "south": {"uv": [7.9, 7.9, 7.94, 8.1], "texture": "#0"}, "west": {"uv": [7.9, 7.9, 9.35, 8.1], "texture": "#0"}, "up": {"uv": [7.9, 7.9, 7.94, 9.35], "texture": "#0"}, "down": {"uv": [7.9, 7.9, 7.94, 9.35], "texture": "#0"} } }, { "from": [0.2, 11, 14.6], "to": [15.8, 13, 15], "faces": { "north": {"uv": [7.9, 7.9, 9.46, 8.1], "texture": "#0"}, "east": {"uv": [7.9, 7.9, 7.94, 8.1], "texture": "#0"}, "south": {"uv": [7.9, 7.9, 9.46, 8.1], "texture": "#0"}, "west": {"uv": [7.9, 7.9, 7.94, 8.1], "texture": "#0"}, "up": {"uv": [7.9, 7.9, 9.46, 7.94], "texture": "#0"}, "down": {"uv": [7.9, 7.9, 9.46, 7.94], "texture": "#0"} } }, { "from": [-0.2, 11, 0.5], "to": [0.2, 13, 15], "faces": { "north": {"uv": [7.9, 7.9, 7.94, 8.1], "texture": "#0"}, "east": {"uv": [7.9, 7.9, 9.35, 8.1], "texture": "#0"}, "south": {"uv": [7.9, 7.9, 7.94, 8.1], "texture": "#0"}, "west": {"uv": [7.9, 7.9, 9.35, 8.1], "texture": "#0"}, "up": {"uv": [7.9, 7.9, 7.94, 9.35], "texture": "#0"}, "down": {"uv": [7.9, 7.9, 7.94, 9.35], "texture": "#0"} } } ], "display": { "thirdperson_righthand": { "translation": [-0.25, -2.75, 0], "scale": [0.3, 0.3, 0.3] }, "thirdperson_lefthand": { "translation": [-0.25, -2.75, 0], "scale": [0.3, 0.3, 0.3] }, "firstperson_righthand": { "rotation": [-9, 115, 15], "translation": [0, 1.25, -1.75], "scale": [0.5, 0.5, 0.5] }, "firstperson_lefthand": { "rotation": [-9, 115, 15], "translation": [0, 1.25, -1.75], "scale": [0.5, 0.5, 0.5] }, "ground": { "rotation": [40, 0, 0], "translation": [0, -2.5, 0], "scale": [0.5, 0.5, 0.5] }, "gui": { "rotation": [0, 180, 0] }, "head": { "translation": [0, 0, 0.25], "scale": [0.82773, 0.73594, 0.9] }, "fixed": { "translation": [0, 0, 8.75] } }, "groups": [ 0, { "name": "straps", "origin": [0, 0, 0], "color": 0, "children": [1, 2, 3] } ] } ```
