I'm making a mod with spears in it and when I try to render the spear as just an arrow it decides it wants to be a white box (kinda fun for pixel-arting villager houses though). How would I get it to render even just as a normal arrow.

 

My main mod file

public class mainMod_XXX {

 

static EnumToolMaterial toolIRON = EnumHelper.addToolMaterial("IRON", 2, 250, 6.0F, 2, 14);

static EnumToolMaterial toolGOLD = EnumHelper.addToolMaterial("GOLD", 0, 32, 12.0F, 0, 22);

static EnumToolMaterial toolDIAMOND = EnumHelper.addToolMaterial("DIAMOND", 3, 1561, 8.0F, 3, 10);

static EnumToolMaterial toolSTONE = EnumHelper.addToolMaterial("STONE", 1, 131, 4.0F, 1, 5);

static EnumToolMaterial toolWOOD = EnumHelper.addToolMaterial("WOOD", 0, 59, 2.0F, 0, 15);

 

//Spears

public static final Item ironSpear = new ItemSpear(9104, toolIRON, 1).setIconCoord(2, 0).setItemName("ironSpear");

public static final Item goldSpear = new ItemSpear(9106, toolGOLD, 2).setIconCoord(4, 0).setItemName("goldSpear");

public static final Item diamondSpear = new ItemSpear(9105, toolDIAMOND, 3).setIconCoord(3, 0).setItemName("diamondSpear");

public static final Item stoneSpear = new ItemSpear(9103, toolSTONE, 4).setIconCoord(1, 0).setItemName("stoneSpear");

public static final Item woodSpear = new ItemSpear(9102, toolWOOD, 5).setIconCoord(0, 0).setItemName("woodSpear");

 

// The instance of your mod that Forge uses.

        @Instance("weapons")

        public static mainMod_XXX instance;

       

        @PreInit

        public void preInit(FMLPreInitializationEvent event) {

                // Stub Method

        }

       

        public void init(FMLInitializationEvent preEvent) {

       

        }

       

        @Init

        public void load(FMLInitializationEvent event)

        {

        LanguageRegistry.addName(ironSpear, "Iron Spear");

        LanguageRegistry.addName(diamondSpear, "Diamond Spear");

        LanguageRegistry.addName(goldSpear, "Gold Spear");

        LanguageRegistry.addName(woodSpear, "Wood Spear");

        LanguageRegistry.addName(stoneSpear, "Stone Spear");

        }

       

        @PostInit

        public void postInit(FMLPostInitializationEvent event) {

                // Stub Method

        }

       

        public void load()

        {

                MinecraftForgeClient.preloadTexture("/Mod_XXX/textures.png");

        }

       

        public void AddRenderer(Map map)

        {

                map.put(EntitySpear.class, new RenderArrow());

        }

}

 

Item Spear is pretty much sword code mixed with bow code.

 

EntitySpear is an exact duplicate of EntityArrow except with a bunch of renames to make it work.

 

RenderSpear

Also if you could point me towards the bit in the render spear code where I could elongate the arrow/spear that would be great 

unrelated but why do you create new enum tool mats with the same as the regular enums?

Originally I was going to change the weapon damage through that but I found a better way and I haven't taken out the repetitive mats yet.

I also tried making a throwable item and that too is a white box when it's thrown.

Where's your proxy? Also AddRenderer doesn't get called. You have to register your stuff through RenderingRegistry. And for that you'll need to use a proxy, since you cannot use the RenderingRegistry on a server.

Look here on how to use the Proxy system: http://www.minecraftforge.net/wiki/Basic_Modding

Then look at the RenderingRegistry class or look in the wiki on how to register your renderer.

Ok, I created a common and client proxy and put this in the client proxy

[embed=425,349]@Override

    public void load()

    {       

        RenderingRegistry.registerEntityRenderingHandler(EntityFireB.class, new RenderFireball(0.5F));

    }[/embed]

But it doesn't work, it doesn't give me any errors but my throwable item is still a white cube (I'll be using my Fireball as an example for now because the code is much skinnier)

Please help, I bet it's a simple error and I'm a noob at java so I can't find it.

Should I make my own render class?

and how do you make a renderer?

I tried copying and pasting the arrow render code and other throwable objects render code for the renderer but it didn't work.

how would i go about useing an existing renderer? like the one for the snowball?

Shouldn't you put

 

public void addRenderer(Map map)

{

  map.put(EntitySpear.class, new RenderSpear());

}

 

Since you made your own RenderSpear, you should use RenderSpear, instead of RenderArrow, I suppose.

In my mod I do the following

 

ClientProxy

void registerRenders()
{
                EntityRegistry.registerGlobalEntityID(EntityLaserBolt.class, "LaserBolt", ModLoader.getUniqueEntityId());
                RenderingRegistry.registerEntityRenderingHandler(EntityLaserBolt.class, new RenderLaserBolt());
}

 

In my mod class

@Init
public void load(FMLInitializationEvent event) throws Exception {
EntityRegistry.registerModEntity(EntityLaserBolt.class, "LaserBolt", 2, instance, 160, 1, false);
//2 is an index - get unique for every other entity
//160 I cant really rembember what it does
//1 is refresh rate - for some other entities You may give bigger values, if you want them to render every x ticks
}

 

Also note That in Your Spear entity you will need a constructor, which takes only World as parameter (even if You don't use it in Your code) - otherwise entity will be invisible.
