Hi!

As the title says, I want to make a custom bounding box for my block. However, when I try to register my event, it doesn't get called. What did I do wrong?

 

This is in my main class: 

@Mod.EventBusSubscriber(bus=Mod.EventBusSubscriber.Bus.MOD)
  public static class RegistryEvents {
  // Other events
  // ...

  @SubscribeEvent
  public void onBlockHighlight(final DrawBlockHighlightEvent event) throws Exception {
    // For testing
    event.setCanceled(true);
    // Currently empty
    ModSelectionBoxes.Draw(event);
  }
}

 

If my method finally gets called, what should I use to draw my bounding box?

    Sleep(1000);
  end;
  println('Okay, nothing to worry, I''m alive!');
  println('So... somebody can give me a coffee?');
  println('I know it''s Pascal, and not Java, but I love it :D.');
end;

That's not the event bus for this event.

Okay, I moved it to the bus=Mod.EventBusSubscriber.Bus.FORGE bus, now it gets called. So... how should I draw in it? The only thing I managed to do is to hide the outline of my own block.

I want to make myself a wrench, so when I click my machines side with it, it sets it to closed, normal, out, or in, I'm able to implement that. What I want to do is to create the same outline but white, and then to make simple line symbols on the sides of the block. I may want to make it so every side of the highlight is visible, not just what I should see.

So... I have some kind of a rendering going on, but for some reason, my outline only renders if I look at the block from 2 specific sides, and the outline's Y value is always the player's height. 

public class ModSelectionBoxes {

    public static boolean Draw(DrawBlockHighlightEvent event) {
        if(event.getTarget().getType() == RayTraceResult.Type.BLOCK) {
            BlockPos blockPos = new BlockPos(event.getTarget().getHitVec());
            BlockState blockState = Minecraft.getInstance().world.getBlockState(blockPos);
            TileEntity tileEntity = Minecraft.getInstance().world.getTileEntity(blockPos);

            if (tileEntity instanceof BatteryTile) {
                ClientPlayerEntity player = Minecraft.getInstance().player;
                GlStateManager.enableBlend();
                GlStateManager.blendFuncSeparate(GlStateManager.SourceFactor.SRC_ALPHA, GlStateManager.DestFactor.ONE_MINUS_SRC_ALPHA, GlStateManager.SourceFactor.ONE, GlStateManager.DestFactor.ZERO);
                GlStateManager.lineWidth(2.5F);
                GlStateManager.disableTexture();
                GlStateManager.depthMask(false);

                AxisAlignedBB box1 = new AxisAlignedBB(blockPos.getX() + 0.0f, blockPos.getY() + 0.0f, blockPos.getZ() + 0.0f,
                        blockPos.getX() + 1.0f, blockPos.getY() + 1.0f, blockPos.getZ() + 1.0f);

                if (blockState.getMaterial() != Material.AIR && event.getInfo().getRenderViewEntity().getEntityWorld().getWorldBorder().contains(blockPos))
                {
                    float partialTicks = event.getPartialTicks();
                    double d3 = player.lastTickPosX + (player.posX - player.lastTickPosX) * (double)partialTicks;
                    double d4 = player.lastTickPosY + (player.posY - player.lastTickPosY) * (double)partialTicks;
                    double d5 = player.lastTickPosZ + (player.posZ - player.lastTickPosZ) * (double)partialTicks;

                    WorldRenderer.drawSelectionBoundingBox(box1.grow(0.0020000000949949026D).offset(-d3, -d4, -d5), 1.0F, 1.0F, 1.0F, 1.0F);
                }

                GlStateManager.depthMask(true);
                GlStateManager.enableTexture();
                GlStateManager.disableBlend();
                return true;
            }
        }
        return false;
    }

}

 

By the way... this is how I call it: 

@SubscribeEvent
public static void onBlockHighlight(final DrawBlockHighlightEvent event) {
	event.setCanceled(ModSelectionBoxes.Draw(event));
}

 

Any idea how to fix it? 

procedure WakeMeUp(Integer plusTime);
var
  I: Integer;
begin
  for I := 0 to plusTime do begin
    println('One more minute!');
    Sleep(1000);
  end;
  println('Okay, nothing to worry, I''m alive!');
  println('So... somebody can give me a coffee?');
  println('I know it''s Pascal, and not Java, but I love it :D.');
end;

I was able to make it appear at the right place, but it's still only visible from 3 sides, and when I sneak its position gets lower than it should be. Any ideas? 

procedure WakeMeUp(Integer plusTime);
var
  I: Integer;
begin
  for I := 0 to plusTime do begin
    println('One more minute!');
    Sleep(1000);
  end;
  println('Okay, nothing to worry, I''m alive!');
  println('So... somebody can give me a coffee?');
  println('I know it''s Pascal, and not Java, but I love it :D.');
end;

So I managed to make my rendering almost perfect. It renders what I want, and how I want it to. It works from all sides now. My wrench is currently the Diamond Hoe for testing, of course, I'll change that. My only problem is that the Y-axis isn't affected by the partial ticks, and it makes my outline fuzz while flying / while the sneak animation goes on. Any ideas what to add so it's stable and not fuzzy?

Code 

/* Imports */

public class ModSelectionBoxes {

    public static boolean Draw(DrawBlockHighlightEvent event) {
        if(event.getTarget().getType() == RayTraceResult.Type.BLOCK) {
            ClientPlayerEntity player = Minecraft.getInstance().player;
            World world = Minecraft.getInstance().world;
			// Offsetted raytrace result, so it goes inside the block a bit. Now I get the correct position.
            BlockPos blockPos = new BlockPos(event.getTarget().getHitVec().add(event.getInfo().getLookDirection().scale(0.1d)));
            BlockState blockState = world.getBlockState(blockPos);
            TileEntity tileEntity = world.getTileEntity(blockPos);

            if (player.getHeldItem(Hand.MAIN_HAND).getItem().equals(Items.DIAMOND_HOE) && !event.getInfo().isThirdPerson())
                if (tileEntity instanceof BatteryTile || tileEntity instanceof SolidFuelGeneratorTile) {
                    GlStateManager.enableBlend();
                    GlStateManager.blendFuncSeparate(GlStateManager.SourceFactor.SRC_ALPHA, GlStateManager.DestFactor.ONE_MINUS_SRC_ALPHA, GlStateManager.SourceFactor.ONE, GlStateManager.DestFactor.ZERO);
                    GlStateManager.disableTexture();
                    GlStateManager.depthMask(false);
                    if (player.isSneaking())
                        GlStateManager.disableDepthTest();

                    AxisAlignedBB box = new AxisAlignedBB(blockPos.getX() + 0.0f, blockPos.getY() + 0.0f, blockPos.getZ() + 0.0f,

                            blockPos.getX() + 0.8f, blockPos.getY() + 0.8f, blockPos.getZ() + 0.0f);

                            blockPos.getX() + 0.8f, blockPos.getY() + 0.8f, blockPos.getZ() + 1.0f);

                    double partialTicks = event.getPartialTicks();
					// This isn't properly affected by the partial ticks. I need to fix this.
                    double eyeOffset = player.getEyePosition((float)partialTicks).y - player.posY;

                    double d3 = player.lastTickPosX + (player.posX - player.lastTickPosX) * partialTicks;

I still didn't manage to make my block's outline stable, but now I have another problem. I get the tile entity with world.getTileEntity, which should be fine, but when I try to access any of its values, they're all 0. I'm accessing them by using ((MyTileEntityType)TileEntity).ExampleVariable. I tried to access its inventory, its energy handler, and even some basic integer values inside it, they aren't null, but they don't have their real values in them, whilst their nbt has those values correctly. Any ideas? I'm sitting on this thing for like a day now...

The client does not magically have the server's values for your TE.

For values that do not change frequently, check this post which explains syncing the data (1.12.2 names but the concept is exactly the same):

 

Thank you very much! Now my values are updated when I change them, and they get sent to the client as well. Now the only thing is still in my post above, but I'll think about it a bit more. 

procedure WakeMeUp(Integer plusTime);
var
  I: Integer;
begin
  for I := 0 to plusTime do begin
