[1.11.2] Show multiple bounding boxes

[MSpace-Dev]

Hey all,

 

I'm trying to get my custom model to display multiple bounding boxes. I;ve managed to set up the collision correctly, but I'm not sure how to display these collision boxes. Here is my code so far.

 

	private static final AxisAlignedBB PILLAR0 = new AxisAlignedBB(0.875D, 0.0D, 0.875D, 1.03125D, 1.09375D, 1.03125D);
	private static final AxisAlignedBB PILLAR1 = new AxisAlignedBB(0.96875D, 1.0625D, 0.96875D, 1.09375D, 1.1875D, 1.09375D);
	private static final AxisAlignedBB PILLAR2 = new AxisAlignedBB(1.0625D, 1.125D, 1.0625D, 1.15625D, 1.3125D, 1.15625D);
	private static final AxisAlignedBB PILLAR3 = new AxisAlignedBB(1.0D, 1.28125D, 1.0625D, 1.09375D, 1.4375D, 1.15625D);
	private static final AxisAlignedBB PILLAR4 = new AxisAlignedBB(0.96875D, 1.40625D, 1.03125D, 1.03125D, 1.5625D, 1.09375D);

	@Override
	public void addCollisionBoxToList(IBlockState state, World worldIn, BlockPos pos, AxisAlignedBB entityBox, List<AxisAlignedBB> collidingBoxes, @Nullable Entity entityIn, boolean p_185477_7_)
	{
		for (AxisAlignedBB axisAlignedBB : getCollisionBoxes())
		{
			addCollisionBoxToList(pos,entityBox, collidingBoxes, axisAlignedBB);
		}
	}

	private List<AxisAlignedBB> getCollisionBoxes()
	{
		List<AxisAlignedBB> bounding_boxes = new ArrayList<>();
		bounding_boxes.add(PILLAR0);
		bounding_boxes.add(PILLAR1);
		bounding_boxes.add(PILLAR2);
		bounding_boxes.add(PILLAR3);
		bounding_boxes.add(PILLAR4);
      
		return bounding_boxes;
	}

 

[MSpace-Dev]

Yes.

[MSpace-Dev]

Alright, so this is what I have so far. Not sure what method to use to specify coordinates. This drawSelectionBox does not take in min/max coords.

 

@SubscribeEvent
public static void drawBlockHighlight(DrawBlockHighlightEvent event)
{
  BlockPos pos = event.getTarget().getBlockPos();
  World world = event.getPlayer().world;

  if (world.isRemote)
  {
    if (event.getTarget().typeOfHit == RayTraceResult.Type.BLOCK)
    {
      if (world.getBlockState(pos).getBlock() instanceof BlockMod)
      {
        BlockMod block = (BlockMod) world.getBlockState(pos).getBlock();

        for (AxisAlignedBB axisAlignedBB : Reference.BOUNDING_BOXES)
        {
          event.getContext().drawSelectionBox(event.getPlayer(), event.getTarget(), 0, event.getPartialTicks()); // How do I draw the box from my list?
        }
      }
    }
  }
}

Looked through how drawSelectionBox() works. It looks like it automatically takes the collision you set, and draws the bounding box for you.

drawSelectionBoundingBox(iblockstate.getSelectedBoundingBox(this.world, blockpos).grow(0.0020000000949949026D).offset(-d0, -d1, -d2), 0.0F, 0.0F, 0.0F, 0.4F);

 

However, it only does this once. Anyway I can call drawSelectionBoundingBox() myself. I can't call it from event.getContext()

Do that code, but in a for loop.

[MSpace-Dev]

Ok, I'm really close now. But something really odd is happening.

 

In this code:

"Before loop" gets called every tick.

"In loop" never gets called at all, which is bizarre.

 

if (world.getBlockState(pos).getBlock() instanceof BlockMod)
{
  Utils.getLogger().info("Before loop");
  
  for (AxisAlignedBB axisAlignedBB : Reference.BOUNDING_BOXES)
  {
    Utils.getLogger().info("In loop");
    drawSelectionBox(event.getPlayer(), event.getTarget(), world, axisAlignedBB, (double) event.getPartialTicks());
  }
}

 

[Cadiboo]

I would guess that Reference.BOUNDING_BOXES is empty. Place a breakpoint down and see

[MSpace-Dev]

Alright, it is empty. So, I initialised it in another class. However, apparently it did not save. They were all typed there, the file just was not saved. I was 100% convinced that list was not empty, which is why I never considered it. Thanks

 

Anyways, I've been tinkering for a while now, still cannot get these lines to render. here's some info:

My block is at -1071 4 1181

When I hover over the block, this is what I get in the log:

And this is my code in the EventHandler:

@Mod.EventBusSubscriber
public class DrawBlockHighlightEventHandler
{
	@SubscribeEvent
	public static void onDrawBlockHighlight(DrawBlockHighlightEvent event)
	{
		BlockPos pos = event.getTarget().getBlockPos();
		World world = event.getPlayer().world;

		if (event.getTarget().typeOfHit == RayTraceResult.Type.BLOCK)
		{
			if (world.getBlockState(pos).getBlock() instanceof BlockMod)
			{
				Utils.getLogger().info("================== START ==================");
				for (AxisAlignedBB axisAlignedBB : Reference.BOUNDING_BOXES)
				{

					drawSelectionBox(event.getPlayer(), axisAlignedBB, (double) event.getPartialTicks());

				}
				Utils.getLogger().info("================== END ==================");
			}
		}
	}

	private static void drawSelectionBox(EntityPlayer player, AxisAlignedBB axisAlignedBB, double partialTicks) {
		GlStateManager.enableBlend();
		GlStateManager.tryBlendFuncSeparate(GlStateManager.SourceFactor.SRC_ALPHA, GlStateManager.DestFactor.ONE_MINUS_SRC_ALPHA, GlStateManager.SourceFactor.ONE, GlStateManager.DestFactor.ZERO);
		GlStateManager.glLineWidth(2.0F);
		GlStateManager.disableTexture2D();
		GlStateManager.depthMask(false);

		double d0 = player.lastTickPosX + (player.posX - player.lastTickPosX) * partialTicks;
		double d1 = player.lastTickPosY + (player.posY - player.lastTickPosY) * partialTicks;
		double d2 = player.lastTickPosZ + (player.posZ - player.lastTickPosZ) * partialTicks;
		RenderGlobal.drawSelectionBoundingBox(axisAlignedBB.offset(-d0, -d1, -d2), 0.0F, 0.0F, 0.0F, 0.4F);

		AxisAlignedBB newBB = axisAlignedBB.offset(-d0, -d1, -d2);
		Utils.getLogger().info("XYZ: " + newBB.maxX + " " + newBB.maxY + " " + newBB.maxZ);

		GlStateManager.depthMask(true);
		GlStateManager.enableTexture2D();
		GlStateManager.disableBlend();
	}
}

This is the BOUNDING_BOXES initialisation:

public static final AxisAlignedBB[] BOUNDING_BOXES = {
  new AxisAlignedBB(0.875D, 0.0D, 0.875D, 1.03125D, 1.09375D, 1.03125D),
  new AxisAlignedBB(0.96875D, 1.0625D, 0.96875D, 1.09375D, 1.1875D, 1.09375D),

  new AxisAlignedBB(0.96875D, 1.40625D, 1.03125D, 1.03125D, 1.5625D, 1.09375D),
  new AxisAlignedBB(0.875D, 0.0D, 0.875D, 1.03125D, 1.09375D, 1.03125D),
  new AxisAlignedBB(0.96875D, 1.0625D, 0.96875D, 1.09375D, 1.1875D, 1.09375D),

  new AxisAlignedBB(-0.03125D, 0.0D, 0.875D, 0.125D, 1.09375D, 1.03125D),
  new AxisAlignedBB(-0.09375D, 1.0625D, 0.96875D, 0.03125D, 1.1875D, 1.09375D),
  new AxisAlignedBB(-0.15625D, 1.125D, 1.0625D, -0.0625D, 1.3125D, 1.15625D),
  new AxisAlignedBB(-0.15625D, 1.28125D, 1.0D, -0.0625D, 1.4375D, 1.09375D),
  new AxisAlignedBB(-0.09375D, 1.40625D, 0.96875D, -0.03125D, 1.5625D, 1.03125D),
  new AxisAlignedBB(-0.03125D, 0.0D, -0.03125D, 0.125D, 1.09375D, 0.125D),
  new AxisAlignedBB(-0.09375D, 1.0625D, -0.09375D, 0.03125D, 1.1875D, 0.03125D),
  new AxisAlignedBB(-0.15625D, 1.125D, -0.15625D, -0.0625D, 1.3125D, -0.0625D),
  new AxisAlignedBB(-0.09375D, 1.28125D, -0.15625D, 0.0D, 1.4375D, -0.0625D),

};

 

Can clearly see that the coordinates are incorrect. However, I took this code straight from the RenderGlobal class. Not sure what's going wrong.

Yes they are. I offset them in my EventHandler class.

[MSpace-Dev]

Oh, sorry about that. That has got it to work!! Thanks for all the help.

sorry to bump this post but could you by any chance post the solution and help a brother out ?
