Horizontal Bow Renderer?

Posted April 18, 201312 yr

What is the default itemrenderer equipped code? In the minecraft forge docs (http://jd.minecraftforge.net/net/minecraftforge/client/IItemRenderer.ItemRenderType.html) it says to look at net.minecraft.src.ItemRenderer. I did and tried pasting the two methods "renderItem" and "renderItemIn2D", fiddled around with it to not have any visible errors. I ended up with this code...

private static RenderItem renderItem = new RenderItem();
private Minecraft mc;
private RenderBlocks renderBlocksInstance = new RenderBlocks();
private EntityLiving par1EntityLiving;
private int par3;

public boolean handleRenderType(ItemStack item, ItemRenderType type) 
{
 	if (type == ItemRenderType.EQUIPPED) { return true; }
  		return false;
	}

	public boolean shouldUseRenderHelper(ItemRenderType type, ItemStack item, ItemRendererHelper helper) 
	{
 	return false;
	}

@Override
public void renderItem(ItemRenderType type, ItemStack par2ItemStack, Object... data) 
{
	GL11.glPushMatrix();

		Icon icon = par1EntityLiving.getItemIcon(par2ItemStack, par3);

            if (icon == null)
            {
                GL11.glPopMatrix();
                return;
            }

            if (par2ItemStack.getItemSpriteNumber() == 0)
            {
                this.mc.renderEngine.bindTexture("/terrain.png");
            }
            else
            {
                this.mc.renderEngine.bindTexture("/gui/items.png");
            }

            Tessellator tessellator = Tessellator.instance;
            float f = icon.getMinU();
            float f1 = icon.getMaxU();
            float f2 = icon.getMinV();
            float f3 = icon.getMaxV();
            float f4 = 0.0F;
            float f5 = 0.3F;
            GL11.glEnable(GL12.GL_RESCALE_NORMAL);
            GL11.glTranslatef(-f4, -f5, 0.0F);

However when I run the game it throws me an NPE, what am I doing wrong?

What I'm trying to do is making my bow that I'v made render horizontally instead of vertically just to give it a cool little effect.

You just wanna get it to hold / flip at 90 degrees right?

I think, placing GL11.glRotatef(90.0F, 1.0F, 0.0F, 0.0F); or GL11.glRotatef(90.0F, 0.0F, 0.0F, 1.0F); somewhere in the beginning of the code will help you.

If i helped you, don't forget pressing "Thank You" button. Thanks for your time.

Yes, I was thinking something along those lines, but I'm not sure how to get the default 2d renderer code in there and working.

Post a new log after removing that mod, may point to the true culprit, or be a completely different error entirely.
