Do you have a model handy?

[lolgamerbob]

yes

first make sure you have a client proxy class whre yo uregister clientised rendereing stuff. it needs to be registered in the main class like this:

@SidedProxy(clientSide = com.sigurd4.YourModNameHere.References.Client, serverSide = com.sigurd4.YourModNameHere.References.Common)

proxy common should be like this:

public class ProxyCommon {
public void registerRenderInformation(){

}
}

make the proxy client extend proxy common just in case you were to add something there and put another registerRenderInformation and make it override. inside it you can make it call super.registerRenderInformation().

 

thats how you set up the proxies, but now you need to make a renderer for your item and call it in registerRenderInformation in proxyClient like this:

MinecraftForgeClient.registerItemRenderer(YourMainClassHere.YourItem, new RenderYourItem());

 

now make your item render class and call it something like i referenced above but with your item. make use IItemRenderer as interface. first make your constructor where you make a variable be the model that you want to use. it should look something like this:

public class RenderYourItem implements IItemRenderer
{
protected ModelYourItem model;

public RenderYourItem()
{
	model = new ModelYourItem();
}
}

 

now add this to make sure it renders only when equipped:

@Override
public boolean handleRenderType(ItemStack arg0, ItemRenderType arg1) {
	if(arg1 == ItemRenderType.EQUIPPED_FIRST_PERSON || arg1 == ItemRenderType.EQUIPPED)
	{
		return true;
	}
	else
	{
		return false;
	}
}

and add this to make sure it doesnt use the default item rendering method, but your custom model instead:

@Override
public boolean shouldUseRenderHelper(ItemRenderType arg0, ItemStack arg1, ItemRendererHelper arg2)
{
	return false;
}

now add the part where you actually call your model and all that stuff:

	@Override
public void renderItem(ItemRenderType arg0, ItemStack itemstack, Object... data)
{
	if(arg0 == ItemRenderType.EQUIPPED_FIRST_PERSON || arg0 == ItemRenderType.EQUIPPED)
	{
		GL11.glPushMatrix(); //this is so you can change the size and position and rotation of your model so it fits

		Minecraft.getMinecraft().renderEngine.bindTexture(new ResourceLocation("bioshock:textures/entity/weapons/pistol_rapture.png")); //the texture for your model. this is just an example.

		GL11.glRotatef(190F, 1.0F, 0.0F, 0.0F); //rotation (change these to what works best)
		GL11.glRotatef(-13F, 0.0F, 1.0F, 0.0F);
		GL11.glRotatef(-10F, 0.0F, 0.0F, 1.0F);

		if(arg0 == ItemRenderType.EQUIPPED) //because you might want it to be in a different position when in first person.
		{
			GL11.glTranslatef(0.41F, -0.4F, -0.55F); //position (change these to what works best)
		}
		else
		{
			GL11.glTranslatef(0.41F, -0.4F, -0.55F); /7these should be different from the above.
		}

		float scale = 1.1F;
		GL11.glScalef(scale, scale, scale); //size (change these to what works best)

		model.render((Entity)data[1], 0.0F, 0.0F, 0.0F, 0.0F, 0.0F, 0.0625F); //i seriously dont know what these number values do, but it works.

		GL11.glPopMatrix();
	}
}

 

then make sure your model is working liek it should, cause techne has a tendancy to mess things up. this should work for 1.7.2.
