[SOLVED]IItemRenderer not rendering EQUIPPED and EQUIPPED_FIRST_PERSON texture!

[lorizz]

Hi guys I'm lorizz and I need to know why my IItemRenderer class, that is used for a class EXTENDING TO A SWORD, doesn't render my texture in case of EQUIPPED and EQUIPPED_FIRST_PERSON, if I don't use those it renders the texture normally but I need to move the model, so this is why I use IItemRenderer (I use it for another reason that you will may find in my code)!

This is the IItemRenderer class:

package it.exoworld_client.renderer;

import it.exoworld_client.ExoWorld_Client;
import it.exoworld_client.extender.ItemDaggerExtender;
import it.exoworld_client.registry.ItemRegistry;
import it.exoworld_client.watcher.PlayerInformation;
import net.minecraft.client.Minecraft;
import net.minecraft.client.renderer.ItemRenderer;
import net.minecraft.client.renderer.Tessellator;
import net.minecraft.client.renderer.entity.RenderItem;
import net.minecraft.entity.EntityLiving;
import net.minecraft.item.ItemStack;
import net.minecraft.util.Icon;
import net.minecraftforge.client.IItemRenderer;

import org.lwjgl.opengl.GL11;
import org.lwjgl.opengl.GL12;

import cpw.mods.fml.client.FMLClientHandler;

public class ItemDaggerRenderer implements IItemRenderer {

private static RenderItem renderItem = new RenderItem();
private Minecraft mc;

@Override
public boolean handleRenderType(ItemStack item, ItemRenderType type) {
	// TODO Auto-generated method stub
	return type == ItemRenderType.INVENTORY
			|| type == ItemRenderType.EQUIPPED
			|| type == ItemRenderType.EQUIPPED_FIRST_PERSON;
}

@Override
public boolean shouldUseRenderHelper(ItemRenderType type, ItemStack item,
		ItemRendererHelper helper) {
	// TODO Auto-generated method stub
	return false;
}

@Override
public void renderItem(ItemRenderType type, ItemStack item, Object... data) {
	EntityLiving entity = (EntityLiving) data[1];
	ItemRenderer itemRenderer = this.mc.entityRenderer.itemRenderer;
	PlayerInformation props = PlayerInformation.get(Minecraft
			.getMinecraft().thePlayer);
	ItemDaggerExtender dagger = (ItemDaggerExtender) item.getItem();
	int selectedClass = props.getSelectedClass();
	int classConfirm = props.getClassConfirm();
	Icon daggerIcon = dagger.getIconIndex(item);
	Icon daggerWrongClass = ItemRegistry.daggerWrongClass
			.getIconIndex(item);
	if (type == ItemRenderType.INVENTORY) {
		if (classConfirm != 1 && selectedClass != 1) {
			this.renderItem.renderIcon(0, 0, daggerWrongClass, 16, 16);
		} else {
			this.renderItem.renderIcon(0, 0, daggerIcon, 16, 16);
		}
	}
	GL11.glPushMatrix();
	FMLClientHandler.instance().getClient().renderEngine
			.bindTexture("/mods/" + ExoWorld_Client.modid
					+ "/textures/items/dagger/"
					+ dagger.getUnlocalizedName().substring(5) + ".png");
	if(type == ItemRenderType.EQUIPPED) {

	} else if (type == ItemRenderType.EQUIPPED_FIRST_PERSON) {

	}
	GL11.glPopMatrix();
}
}

 

I tried using "Minecraft.getMinecraft().renderEngine.bindTexture()" method but still not working, also I tried using tessellator...crash because of "EntityLiving entity = (EntityLiving) data[1];" and I don't know why, it tells me "ArrayIndexOutOfBounds".

Who can help me? Maybe it doesn't work because it's used for a class that extends to a custom extender that extends to an ItemSword? Does my extender need to extends to an Item? I can make my own ItemSword if I need so.

Thanks! (I'm italian sorry for my bad english...if I made some grammar mistakes)

Hi

 

You may find this link useful

http://greyminecraftcoder.blogspot.com.au/2013/09/custom-item-rendering-using.html

and some sample code

http://greyminecraftcoder.blogspot.com.au/2013/09/sample-code-for-rendering-items.html

 

I'd say the crash is because the caller doesn't always pass an entity in data.  That's why it's got a variable argument list Object... after all.

 

Do you even need the EntityLiving?

 

-TGG

I used the EntityLiving for tessellator, but if it crashes...

EDIT: I have no idea on how to do that, I tried with this.renderItem(); method but it crashes when I equip it! How can I do that? I don't understand at all the code you gave to me

So...you use the EntityLiving to get the ItemRenderer, which you then don't use...

[lorizz]

I don't use it because I DON'T KNOW how to do that, if you can give me the answer or ATLEAST an example.....

[Draco18s]

You also don't need to get the Tessellator from an entity:

 

Tessallator.instance

 

Magic.

 

The better question is:

What are you trying to do?

[lorizz]

I want to render the item texture in EQUIPPED and EQUIPPED_FIRST_PERSON types

[Draco18s]

Are you doing something that requires the item to not render as a default item?

If so, what?

[lorizz]

This is what I wanted to do:

1)Creating an item normally;

2)Changing position and angles of the render in First Person and Third Person.

 

From point 2 I created an IItemRenderer for the angles and position, but when I wrote "case EQUIPPED" or "case EQUIPPED_FIRST_PERSON" the texture's gone...I don't know why, the player has nothing in hand! I can't fix/render this!

You mean these lines?

 

		if(type == ItemRenderType.EQUIPPED) {

	} else if (type == ItemRenderType.EQUIPPED_FIRST_PERSON) {

	}

 

First off, those aren't case statements.

Second, duh.  You're not doing anything.

 

Anyway, you can bind textures through the TextureManager passed as data[1] (the player is data[0] by the way) and ItemRenderer.renderItemIn2D will render an item.  If that doesn't work you can create a fake ItemEntity and render that instead using RenderManager.instance.renderEntityWithPosYaw

Ok, I think I made for myself, but I got an ArrayIndexOutsOfExceptions crash on "EntityLiving entity = (EntityLiving) data[1];"

How can I fix that problem?

[Draco18s]

do this:

 

if(data.length < 2) { return; }

 

See if that helps.

IT WORKS! My god thanks! I can finally make whatever I want! +1
