Render a item above a block?

[gamer1097]

Hi I would like to know the easiest way to make a item render above a block in the world.

[TreeBek]

Have you made an effort to figure it out by yourself?

[TLHPoE]

Try using EntityItem. There's a variable for the amount of time it takes to pick up.

How do I spawn the item in the world above the block? And how would I make it so it just floats there similar to the wand in thaumcraft?

Here's the render function for my TE model:

 

public void render(TileEntity te, double x, double y, double z) {
	TEDisplayPedestal es = (TEDisplayPedestal)te;
	if(es.itemEnt != null) { //store the item entity in the tile entity
		GL11.glPushMatrix();
		GL11.glTranslatef((float)x + 0.5F, (float)y + 0.75F, (float)z + 0.25F);//position where I want it
		GL11.glRotatef(90, 1, 0, 0); //lay the item flat
		RenderHelper.enableStandardItemLighting();
		RenderManager.instance.renderEntityWithPosYaw(es.itemEnt, 0, 0, 0, 0, 0);
		GL11.glPopMatrix();
	}

	GL11.glPushMatrix();
	GL11.glTranslatef((float)x + 0.5f, (float)y - 0.5f, (float)z + 0.5f);
	ResourceLocation rl = new ResourceLocation(es.getModelTexture());
	Minecraft.getMinecraft().renderEngine.bindTexture(rl);
	this.render();
	GL11.glPopMatrix();
}

Where does this code go? And whats the es.itemEnt ?

[Draco18s]

I have that as part of the Model (public class MyModel extends ModelBase).

 

es.itemEnt is just an EntityItem that is stored in the custom tile entity so that I'm not creating a new one all the time (I also force its position, rotation, and age to zero).

I hate to reply to someone else's conversation, but Draco, this seems to render it at different angles and positions each time you place the block down...

It shouldn't.  That code was where I stopped last night, before I did placement angles (my TE now has 4 facings).

Code:

 

 

 

TileEntity item definition

 public EntityItem star = new EntityItem(this.worldObj, this.xCoord, this.yCoord, this.zCoord, new ItemStack(Item.netherStar));

 

TileEntityRenderer

public class RenderAdvCrafter extends TileEntitySpecialRenderer
{

@Override
public void renderTileEntityAt(TileEntity tileentity, double x, double y, double z, float f)
{

	TileAdvCrafter tile = (TileAdvCrafter) tileentity;

	if(tile.star != null)
	{
            tile.star.setPositionAndRotation(0, 0, 0, 0, 0);
            tile.star.age = 0;

		GL11.glPushMatrix();
		GL11.glTranslatef((float)x+0.5F, (float)y+0.8F, (float)z+0.25F);
		GL11.glRotatef(90, 1, 0, 0);
		GL11.glScalef(1.5F, 1.5F, 1.5F);
		RenderHelper.enableStandardItemLighting();
		RenderManager.instance.renderEntityWithPosYaw(tile.star, 0, 0, 0, 0, 0);
		GL11.glPopMatrix();
	}
}

}

 

 

 

 

The angles of each star change upon world reload also. It seems to be ignoring the rotational infomation it is given...

Ah!  I see your problem.

 

This is from my tile entity:

 

@Override
public void onInventoryChanged() {
	super.onInventoryChanged();
	if(contents[0] != null) {
		itemEnt = new EntityItem(this.worldObj, this.xCoord, this.yCoord, this.zCoord, contents[0]);
		itemEnt.hoverStart = 0; //this is making it be off-center
		itemEnt.rotationYaw = 0; //this is what's making it rotate for you
		itemEnt.motionX = 0; //zero out these just in case
		itemEnt.motionY = 0;
		itemEnt.motionZ = 0;
	}
	else {
		itemEnt = null;
	}
}

	}
}

 

Ah, thanks!
