[SOLVED][1.10.2]Entity Projectile Invisible

[Mark136]

Hello, I created a custom firebal projectile but it doest render well.

the particles renders and the entity exist, only the projectile does'nt render.

 

I think it is something stupid but can't find it.

 

so here you can see my renderOpalShot Class, and I already checked that the doRender and the getEntityTexture both got called:

 

@SideOnly(Side.CLIENT)
public class RenderOpalShot extends Render<EntityOpalShot>{

	private ResourceLocation location = new ResourceLocation("mark13695","textures/entity/Opal1.png");
	
	public RenderOpalShot(RenderManager renderManager) {
		super(renderManager);
	}
	@Override
	 public void doRender(EntityOpalShot entity, double x, double y, double z, float entityYaw, float partialTicks)
	    {
		GlStateManager.pushMatrix();
        this.bindEntityTexture(entity);
        GlStateManager.translate((float)x, (float)y, (float)z);
        GlStateManager.enableRescaleNormal();
        GlStateManager.scale(0.5F, 0.5F, 0.5F);
        TextureAtlasSprite textureatlassprite = Minecraft.getMinecraft().getRenderItem().getItemModelMesher().getParticleIcon(MarkItems.OpalShotIcon);
        Tessellator tessellator = Tessellator.getInstance();
        VertexBuffer vertexbuffer = tessellator.getBuffer();
        float f = textureatlassprite.getMinU();
        float f1 = textureatlassprite.getMaxU();
        float f2 = textureatlassprite.getMinV();
        float f3 = textureatlassprite.getMaxV();
        
        GlStateManager.rotate(180.0F - this.renderManager.playerViewY, 0.0F, 1.0F, 0.0F);
        GlStateManager.rotate((float)(this.renderManager.options.thirdPersonView == 2 ? -1 : 1) * -this.renderManager.playerViewX, 1.0F, 0.0F, 0.0F);

        if (this.renderOutlines)
        {
            GlStateManager.enableColorMaterial();
            GlStateManager.enableOutlineMode(this.getTeamColor(entity));
        }

        vertexbuffer.begin(7, DefaultVertexFormats.POSITION_TEX_NORMAL);
        vertexbuffer.pos(-0.5D, -0.25D, 0.0D).tex((double)f, (double)f3).normal(0.0F, 1.0F, 0.0F).endVertex();
        vertexbuffer.pos(0.5D, -0.25D, 0.0D).tex((double)f1, (double)f3).normal(0.0F, 1.0F, 0.0F).endVertex();
        vertexbuffer.pos(0.5D, 0.75D, 0.0D).tex((double)f1, (double)f2).normal(0.0F, 1.0F, 0.0F).endVertex();
        vertexbuffer.pos(-0.5D, 0.75D, 0.0D).tex((double)f, (double)f2).normal(0.0F, 1.0F, 0.0F).endVertex();
        tessellator.draw();

        if (this.renderOutlines)
        {
            GlStateManager.disableOutlineMode();
            GlStateManager.disableColorMaterial();
        }

        GlStateManager.disableRescaleNormal();
        GlStateManager.popMatrix();
        super.doRender(entity, x, y, z, entityYaw, partialTicks);
	    }
	
	

	@Override
	protected ResourceLocation getEntityTexture(EntityOpalShot entity) {
		return location;	
	}
}

yeah, as you see, I copied most of the code from EntityFireBall...

 

this file is called in clientproxy, with all my other entities that havend Spawning problems

 public static void registerRenderers(){
    	//...
    	RenderingRegistry.registerEntityRenderingHandler(EntityOpalShot.class, RenderOpalShot::new);
    	
    }
	

and this is called in the pre-Init method in the mainfile:

@EventHandler
	public void PreInit(FMLPreInitializationEvent Event){
		
		//...
		ClientProxy.registerRenderers();
		
	}
@EventHandler
	public void init(FMLInitializationEvent Event){
		
		//...
        
        MobRegistry.init();
       
	}

 

and here I registered my mobs:

public static void init(){

//...
	
	EntityRegistry.registerModEntity(EntityOpalShot.class, "OpalShot", 23, MainRegistry.instance, 80, 3, true);

}

thanks for helping me.

changed the thread title to let see it is solved now

You can't do this. This will 100% crash the dedicated server.  Remember: the client proxy cannot load on the server, it references classes that don't exist.  The only way to reference proxy methods is through an instance.

Mainmod.instance.proxy.registerRenderers();

[Mark136]

@SideOnly(Side.CLIENT)
public class ClientProxy extends CommonProxy {

I havend done something with the proxies for over a year, but everything is working. No Crashes(proxy part)

 

only added the line for the new Entity Projectile

 

and that time the Old RegisterEntityRenderingHandler became Depricated in favor of the IRenderFactory thing

It won't crash when you run it as a client, but it will crash when you run it as a server.

Yes but this:

ClientProxy.registerRenderers();

Is in common code and that's a static reference to your client proxy.

 

Next to the run button is a dropdown, click that and click "run server."

[Mark136]

Ok, Thanks, I didn't knew I could run a server in Eclipse. now i had far more errors than this one, I didn't registered the the client things well, now I have separated the client things and the server things. and now the client and server both working. but it still didn't fix the problem.

this is how my client proxy looks right now

public class ClientProxy extends CommonProxy {

@Override
    public void preInit(FMLPreInitializationEvent event) {
super.preInit(event);
this.registerRenderers();
}

  public void registerRenderers(){
  RenderingRegistry.registerEntityRenderingHandler(EntityOpalShot.class, RenderOpalShot::new);
}

Show your EntityOpalShot class

ok, it is almost fully copied from EntityThrowable with some small changes

An Entity must have a constructor with just a World argument, otherwise the client cannot spawn it and it cannot be reloaded from disk.

ok, this are the constructors now:

public EntityOpalShot(World worldIn)
    {
		super(worldIn);
        this.xTile = -1;
        this.yTile = -1;
        this.zTile = -1;
        this.setSize(0.25F, 0.25F);
      
    }

    public EntityOpalShot(World worldIn, EntityLivingBase throwerIn, int ID)
    {
    	this(worldIn, throwerIn.posX, throwerIn.posY + (double)throwerIn.getEyeHeight() - 0.10000000149011612D, throwerIn.posZ, ID);
        this.shooter = throwerIn;
    }

    public EntityOpalShot(World worldIn, double x, double y, double z, int ID)
    {
    	this(worldIn);
        this.setPosition(x, y, z);
        this.BurstID = ID;
    }

unfortunately, nothing happened

You can try offsetting it by a couple blocks and see what happens, it may be colliding with the thrower. Also if your using most of EntityThrowable code why not just extend from it and override/add stuff. Minecraft also has an EntityFireball class that you could check out.

But yeah, working Git repo will make helping you out now and possibly in the future much easier.

hey, I already checked this with particle trails, and when the projectile lands in the water. the particles spawn, but the projectile doesn't

I currently busy with separating the projectile from the rest of my code so its easier to read. I also gonna create a Git repo of it. 

 

I don't extend the entity Throwable because I want to change the character a bit. the gravity, the valocity ect.

also, if i shoot an entityFireBall. the fireball goes through everything.

here is ItemWand class. this is the Item how I shoot the projectile. Git repo is coming!

public class MarkWand extends Item {
	
	/** 
	 * custom EnumMaterial to calculate some values that I need for 
	 * my combat system.
	 *  */
	private EnumMaterial material;
	private float AttackDamage;
	private int Cooldown = 0;
	
	public MarkWand(EnumMaterial Material){
		this.material = Material;
		this.maxStackSize = 1;
		this.setMaxDamage(Material.getMaxUses());
	}

	/** TODO: Does Nothing, Why I have this, this is for holding a Tool right? */
	@SideOnly(Side.CLIENT)
    public boolean isFull3D()
    {
        return true;
    }
	
	@Override
	public ActionResult<ItemStack> onItemRightClick(ItemStack I, World W, EntityPlayer Player, EnumHand hand)
    {
		if(this.Cooldown < 1){
		this.Cooldown = 30;
		
		Entity GemBall;
		
		if(this == MarkItems.Wand1){
			GemBall = new EntityOpalShot(W, Player, 0);
			
			
			((EntityOpalShot) GemBall).setHeadingFromThrower(Player, Player.rotationPitch, Player.rotationYaw, 0.0F, 1.5F, 1.0F);
          
			I.damageItem(1, Player);
		}
		else{
		
		Vec3d aim = Player.getLookVec();
		
		GemBall = new EntitySmallFireball(W, Player, 1, 1, 1);
		
		((EntitySmallFireball)GemBall).setPosition(
				Player.posX + aim.xCoord * 1.5D,
				Player.posY + aim.yCoord * 1.5D,
				Player.posZ + aim.zCoord * 1.5D);
		((EntitySmallFireball)GemBall).accelerationX = aim.xCoord * 0.1;
		((EntitySmallFireball)GemBall).accelerationY = aim.yCoord * 0.1;
		((EntitySmallFireball)GemBall).accelerationZ = aim.zCoord * 0.1;
		}
		 
		W.spawnEntityInWorld(GemBall);
		
		
		
    }
		return new ActionResult(EnumActionResult.PASS, I);
    }
	
	/** I want a cooldown period between the shots, so this is why I have this */
	@Override
	public void onUpdate(ItemStack itemstack, World world, Entity entity, int i, boolean B) {
	if (this.Cooldown > 0){
		this.Cooldown--;
	}
	}
}

...

 

I was registering the Mobs in init instead of pre-init, so the rendering part was registered before the EntityRegistry. resulting in an invisible projectile.

why the projectile was going through blocks is that I forgot the !world.isRemote() check in ItemWand.

now the projectile is spawning well.

 

thx for the help
