Rendering a 3D item as a throwable item

darty11 · March 7, 2014

Change it to

Icon icon;
if(this.field_94151_a!=null)
{
icon = this.field_94151_a.getIconFromDamage(0);
}
else
{
icon=Soccer.ball.getIconFromDamage(0);
}

Im not sure what else to try at this point. Ive been looking for whats making the ball not render and remain invisible and havent had any luck yet.

darty11 · March 7, 2014

So you didn't get any errors and the ball didn't render?

PeterRDevries · March 7, 2014

Have you taken a look at the minecraft arrow source?

Thornack · March 7, 2014

Ok I found the problem it says that ball cannot be resolved in field or type (I missed the error)

TheGreyGhost · March 7, 2014

Hi

Is there a reason you're using Minecraft 1.5? If you upgrade to 1.6.4 or 1.7.2 and post your code as a zip or on GitHub, we could try it debugging it ourselves if you like.

Some of my other methods dont work in other versions yet so I havent upgraded. I fixed the error in the change but minecraft still crashes with the following errors.

        ball = new Ball(5000);
        LanguageRegistry.addName(ball, "Ball");

Awesome! That doesnt crash Minecraft now but it throws my 2D inventory icon for the ball and this ball doesnt show up on the ground as an entity it just spawns snowball particles and does damage

darty11 · March 7, 2014

That is because it seems your render class is for rendering icons. You are probably going to have to use a different render class.

I made one that should help you, but it uses 1.7 code, so you might have to change up the methods.

You will also need to revert your

RenderingRegistry.registerEntityRenderingHandler(EntityBall.class, new RenderBall([insert item here])

in your client proxy back to

]RenderingRegistry.registerEntityRenderingHandler(EntityBall.class, new RenderBall()

As to your other problem, that is because you copied all the code in the snowball class, so it is going to act like a snowball regardless of how it looks. You need to change it's behavior code to make it act like a ball.

Ok, try to code the correct behavior into your ball now. If you have problems, ask.

Thornack · May 7, 2014

I have now upgraded my code to 1.7.2 and alot of stuff broke. The renderers included. I am not sure how to get the textures for my ball in 1.7.2. It renders in my hand in 3D and as a dropped item but the texture is missing and it does not render when thrown. I have managed to get rid of all of the errors by commenting out

 
Minecraft.getMinecraft().renderEngine
	.bindTexture("/mods/soccer/textures/items/Ball3D.png");

in both renderers (the one that handles in flight rendering and the one that handles the rest)

        GL11.glRotatef(180.0F - par8, 0.0F, 1.0F, 0.0F);

}

Renderer for the rest

public class ItemRenderBall implements IItemRenderer {

protected ItemModelBall modelBall;
//private static final ResourceLocation itemTexture = new ResourceLocation("");

		GL11.glRotatef(90, 0, 1, 0);
		GL11.glRotatef(230, 1, 0, 0);

     */
    protected ResourceLocation getEntityTexture(Entity Ball)
    {
        return this.itemTexture;
    }
}

and I registered the item in my main mod class as so

@EventHandler Public void preInit(FMLPreInitializationEvent preEvent) {
Item ball = new Ball(5000).setUnlocalizedName("Ball");
			GameRegistry.registerItem(ball,
			"Ball");
	MinecraftForgeClient.registerItemRenderer(Ball,
			(IItemRenderer) new ItemRenderBall());
	registerTileEntity();
}

Also Client Proxy didnt change and Common Proxy didnt change

and I know that to the inflight renderer I have to add

private static final ResourceLocation itemTexture = new ResourceLocation("");

and

protected ResourceLocation getEntityTexture(Entity Ball)
    {
        return this.itemTexture;
    }

but im not sure how to specify the resource locations and I dont know what to add to the other renderer that implements IItemRenderer. I have an assets package

assets.soccer.textures.items

and I have set up the lang file but im not sure how to proceed and get the ball to render with its texture and render in flight. It currently renders in my hand and on the ground as a 3D object but without its proper texture.

I added the changes you suggester and now the ball renders but with a purple colour and doesn't render during flight at all (when before it rendered weird with a bunch of textures overlayed on it where some parts were clear and others weren't and didn't render during flight either).

darty11 · May 7, 2014

Make sure the resource locations I put in are actually the right ones.

Thornack · May 7, 2014

my textures are organized as follows in my modding folder I have a forge folder and inside that folder the path is src/soccer/assets/soccer/textures/items/Ball3D.png I have tried inputting and I still get the purple.

private static final ResourceLocation BallTextures = new ResourceLocation(yourmod.modid+"Ball3D.png");

private static final ResourceLocation BallTextures = new ResourceLocation(yourmod.modid+"items/Ball3D.png");

private static final ResourceLocation BallTextures = new ResourceLocation(yourmod.modid+"textures/items/Ball3D.png");

private static final ResourceLocation BallTextures = new ResourceLocation(yourmod.modid+"soccer/textures/items/Ball3D.png");

private static final ResourceLocation BallTextures = new ResourceLocation(yourmod.modid+"assets/soccer/textures/items/Ball3D.png");

private static final ResourceLocation BallTextures = new ResourceLocation(yourmod.modid+"soccer/assets/soccer/textures/items/Ball3D.png");

private static final ResourceLocation BallTextures = new ResourceLocation(yourmod.modid+"src/soccer/assets/soccer/textures/items/Ball3D.png");

Is it a problem with how I set up my resource locations? Do they have to be in the "src/main/resources/..." directory?

Thornack · May 8, 2014

I havent had any luck yet with this so any ideas/suggestions are very much appreciated I will post all the working code once this is solved and might write a tutorial after on how to add 3D throwable items

darty11 · May 8, 2014

Are your assets imported into eclipse? And do you have a folder in eclipse that says assets.{youmodnamehere}.textures.tems?

Thornack · May 8, 2014

Yes I have "assets.soccer.textures.items" and inside there I have "Ball3D.png" and these are located in the "src/main/resources" folder where the rest of my mod is located in the "src/main/java folder"

Thornack · May 9, 2014

Part 1 is [solved] But it doesnt seem to be thrown and doesnt render in flight

I replaced this line

private static final ResourceLocation itemBallTexture = new ResourceLocation(Soccer.modid+"/assets/soccer/textures/items/Ball3D.png");

with this line

Can I see your imports on your model and render file? Sometimes there can be a faulty import there that prevents everything from working.

	       if (!par2World.isRemote)
       {
           par2World.spawnEntityInWorld(new EntityBall(par2World));
       }

There is the problem. You never move the ball to the players coordinates, nor do you give it a velocity. I bet if you went to 0 0 0 and broke all the blocks around there, you would see a fully functioning rendered ball spawning there every time you threw it. (Don't worry, we all make mistake like this I've honestly done worse.)

Change it to:

[code=] if (!par2World.isRemote)
{
par2World.spawnEntityInWorld(new EntityBall(par2World,par3EntityPlayer));
}[/code]

And the EntityThrowable class will take care of all the velocities and stuff.

Also, try running the server side version, I think the way you are registering your rendering is going to cause problems with server.

Lastly,

I tried your suggestion and it didnt work even when I went to 0,0,0 nothing shows up the ball doesnt seem to throw nor render

Thornack · May 10, 2014

I have made a few changes to the code, and am now trying to get it to render in the inventory before I tackle the in flight rendering again since I couldnt get it to work and need a break, it isnt rendering while being thrown and I have no idea why because when I replaced everything with the egg it worked fine.

This is the updated renderer that handles case ENTITY, case EQUIPPED_FIRST_PERSON, and now case INVENTORY

public class ItemRenderBall implements IItemRenderer {

protected ItemModelBall modelBall;
private static final ResourceLocation itemBallTexture = new ResourceLocation(
		"soccer:textures/items/ball.png");
public ItemRenderBall() {
	modelBall = new ItemModelBall();
}

@Override
public boolean handleRenderType(ItemStack item, ItemRenderType type) {
	switch (type) {
	case EQUIPPED:
	case EQUIPPED_FIRST_PERSON:
	case ENTITY:
                case INVENTORY:
		return true;
	default:
		return false;
	}
}

@Override
public boolean shouldUseRenderHelper(ItemRenderType type, ItemStack item,
		ItemRendererHelper helper) {
	return false;
}
//Renders the Ball in your hand
@Override
public void renderItem(ItemRenderType type, ItemStack item, Object... data) {
	switch (type) {
	case EQUIPPED:
	case EQUIPPED_FIRST_PERSON:
		GL11.glPushMatrix();
		// rotates the item
		GL11.glRotatef(90, 0, 0, 1);
		GL11.glRotatef(90, 0, 1, 0);
		GL11.glRotatef(230, 1, 0, 0);
		GL11.glTranslatef(0, 0.2f, -0.6f);
		Minecraft.getMinecraft().renderEngine.bindTexture(this.itemBallTexture);
		// renders the item
		modelBall.render((Entity) data[1], 0.0f, 0.0f, 0.0f, 0.0f,
				0.0f, 0.0225f);
		GL11.glPopMatrix();

	default:
		break;
		//Renders the Ball on ground
	}
	switch (type) {
	case ENTITY:

		GL11.glPushMatrix();
		// rotates the item and translates the item
		GL11.glRotatef(0, 0, 0, 1);
		GL11.glRotatef(0, 0, 1, 0);
		GL11.glRotatef(180, 1, 0, 0);
		GL11.glTranslatef(0, 0f, 0f);
		Minecraft.getMinecraft().renderEngine.bindTexture(this.itemBallTexture);
		// renders the item
		modelBall.render((Entity) data[1], 0.0f, 0.0f, 0.0f, 0.0f,
				0.0f, 0.0225f);
		GL11.glPopMatrix();
	default:
		break;
	}
switch (type) {
	case INVENTORY:

		GL11.glPushMatrix();
		// rotates the item and translates the item
		GL11.glRotatef(0, 0, 0, 1);
		GL11.glRotatef(0, 0, 1, 0);
		GL11.glRotatef(180, 1, 0, 0);
		GL11.glTranslatef(0, 0f, 0f);
		Minecraft.getMinecraft().renderEngine.bindTexture(this.itemBallTexture);
		// renders the item
		modelBall.render((Entity) data[1], 0.0f, 0.0f, 0.0f, 0.0f,
				0.0f, 0.0225f);
		GL11.glPopMatrix();
	default:
		break;
	}
}
 /**
     * Returns the location of an entity's texture. Doesn't seem to be called unless you call Render.bindEntityTexture.
     */
    protected ResourceLocation getEntityTexture(Entity Ball)
    {
        return this.itemBallTexture;
    }
}

but im getting an error from line

 modelBall.render((Entity) data[1], 0.0f, 0.0f, 0.0f, 0.0f,0.0f, 0.0225f);

where changing (Entity) data[1] to null fixes the error but in game the ball doesnt show up and when you try to puck up a stack the stacknumber shows up so it seems to be there but is invisible in the inventory.
