Posted October 14, 201410 yr Hey everyone, I've checked everywhere, but I can't find a single thing that could be causing my issue. I'm trying to implement a basic 'fireball' using snowball as a basis but I'm not having any luck. The specific problem is that while the projectile fires and impacts, it doesn't render at all. I have added break points into the RenderKBFireball class but they do not fire. My four classes are: KBFireball - contains the item, it's onItemRightClick event, it's presence in creative mode, icon etc. KBEntityFireBall - inheriting from EntityThrowable controls the onImpact RenderKBFireball - the render class, pretty much a direct copy of RenderSnowball KBClasses - the main mod file containing the definition and the registry etc. A few things worth noting: In KBFireball, I'm alternating between firing an actual snowball and my Fireball itself. The fact that the snowball shows is telling me this class is fine. I suspect if anything, it has something to do with my registering of items, but I've tried a lot of variations and had no luck. All of this compiles and runs as well, so no code errors. Thanks in advance Primalfreeze KBFireball public class KBFireball extends Item { private int i = 0; public KBFireball() { super(); setCreativeTab(CreativeTabs.tabCombat); setUnlocalizedName(Reference.MODID + "_" + "kbfireball"); setTextureName(Reference.MODID + ":" + "kbfireball"); } public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer) { if (!par3EntityPlayer.capabilities.isCreativeMode) { // Consume Ammo (this will need to be use mana) --par1ItemStack.stackSize; } // Play the shoot sound par2World.playSoundAtEntity(par3EntityPlayer, "random.bow", 0.5f, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F)); if (!par2World.isRemote) { if ((i % 2) > 0) { par2World.spawnEntityInWorld(new EntitySnowball(par2World, par3EntityPlayer)); i++; } else { par2World.spawnEntityInWorld(new KBEntityFireball(par2World, par3EntityPlayer)); i++; } } return par1ItemStack; } } KBEntityFireball public class KBEntityFireball extends EntityThrowable { private float explosionRadius = 0.5f; public KBEntityFireball(World par1World) { super(par1World); } public KBEntityFireball(World par1World, EntityLivingBase par2EntityLivingBase) { super(par1World, par2EntityLivingBase); } public KBEntityFireball(World par1World, double par2, double par3, double par4) { super(par1World, par2, par3, par4); } protected void onImpact(MovingObjectPosition par1MovingObjectPosition) { this.worldObj.createExplosion(this, this.posX, this.posY, this.posZ, (float)(this.explosionRadius), true); if (!this.worldObj.isRemote) { this.setDead(); } } } RenderKBFireball public class RenderKBFireball extends Render { //private static ResourceLocation texture = new ResourceLocation(Reference.MODID, "textures/items/kbfireball.png"); private Item localItem; private int dmgVal; public RenderKBFireball(Item par1Item) { this(par1Item, 0); } public RenderKBFireball(Item par1Item, int par2Int) { localItem = par1Item; dmgVal = par2Int; } public void doRender(Entity par1Entity, double par2, double par4, double par6, float par8, float par9) { IIcon iicon = localItem.getIconFromDamage(dmgVal); if (iicon != null) { GL11.glPushMatrix(); GL11.glTranslatef((float)par2, (float)par4, (float)par6); GL11.glEnable(GL12.GL_RESCALE_NORMAL); this.bindEntityTexture(par1Entity); Tessellator tessellator = Tessellator.instance; float f = iicon.getMinU(); float f1 = iicon.getMaxU(); float f2 = iicon.getMinV(); float f3 = iicon.getMaxV(); float f4 = 1.0F; float f5 = 0.5F; float f6 = 0.25F; GL11.glRotatef(180.0F - this.renderManager.playerViewY, 0.0F, 1.0F, 0.0F); GL11.glRotatef(-this.renderManager.playerViewX, 1.0F, 0.0F, 0.0F); tessellator.startDrawingQuads(); tessellator.setNormal(0.0F, 1.0F, 0.0F); tessellator.addVertexWithUV((double)(0.0F - f5), (double)(0.0F - f6), 0.0D, (double)f, (double)f3); tessellator.addVertexWithUV((double)(f4 - f5), (double)(0.0F - f6), 0.0D, (double)f1, (double)f3); tessellator.addVertexWithUV((double)(f4 - f5), (double)(f4 - f6), 0.0D, (double)f1, (double)f2); tessellator.addVertexWithUV((double)(0.0F - f5), (double)(f4 - f6), 0.0D, (double)f, (double)f2); tessellator.draw(); GL11.glDisable(GL12.GL_RESCALE_NORMAL); GL11.glPopMatrix(); } } @Override protected ResourceLocation getEntityTexture(Entity par1Entity) { return TextureMap.locationItemsTexture; } } KBClasses @Mod(modid = Reference.MODID, version = Reference.VERSION) public class KBClasses { public static Item fireball; @EventHandler public void preinit(FMLInitializationEvent event) { fireball =new KBFireball(); GameRegistry.registerItem(fireball, "kbfireball"); RenderKBFireball r = new RenderKBFireball(fireball); RenderingRegistry.registerEntityRenderingHandler(KBEntityFireball.class, r); } }
October 14, 201410 yr Where do you register the entity? Check out my mod, Realms of Chaos, here. If I helped you, be sure to press the "Thank You" button!
October 14, 201410 yr Author @Eternaldoom - that was enough for me to figure it all out. I somehow glossed over the registering of an entity in all the examples I found. I suspect because I was looking for other problems, not chunks that were missing. So thanks heaps. For recordkeeping purposes, here is the added code (added in KBClasses.preInit) EntityRegistry.registerGlobalEntityID(KBEntityFireball.class, "KBFireball", uid); EntityRegistry.registerModEntity(KBEntityFireball.class, "KBFireball", uid, this, 80, 10, true); This topic is now solved but I can't see anything letting me mark it as such.
