Now, I saw this post.

I thought, you know, let's add that to my mod. So I basically did the things in there and made some changes. But it doesn't work.

Here's my block class. 

public class BlockAutoMiner extends Block {

	public static final PropertyDirection FACING = BlockHorizontal.FACING;
	public static IProperty ACTIVATED = PropertyBool.create("activated");

	public BlockAutoMiner() {
		super(Material.PISTON);
		setDefaultState(
				blockState.getBaseState().withProperty(FACING, EnumFacing.NORTH).withProperty(ACTIVATED, false));
	}

	@Override
	public void onBlockAdded(World worldIn, BlockPos pos, IBlockState state) {
		setDefaultFacing(worldIn, pos, state);
	}

	private void setDefaultFacing(World worldIn, BlockPos pos, IBlockState state) {
		if (!worldIn.isRemote) {
			IBlockState iblockstate = worldIn.getBlockState(pos.north());
			IBlockState iblockstate1 = worldIn.getBlockState(pos.south());
			IBlockState iblockstate2 = worldIn.getBlockState(pos.west());
			IBlockState iblockstate3 = worldIn.getBlockState(pos.east());
			EnumFacing enumfacing = state.getValue(FACING);

			if (enumfacing == EnumFacing.NORTH && iblockstate.isFullBlock() && !iblockstate1.isFullBlock()) {
				enumfacing = EnumFacing.SOUTH;
			} else if (enumfacing == EnumFacing.SOUTH && iblockstate1.isFullBlock() && !iblockstate.isFullBlock()) {
				enumfacing = EnumFacing.NORTH;
			} else if (enumfacing == EnumFacing.WEST && iblockstate2.isFullBlock() && !iblockstate3.isFullBlock()) {
				enumfacing = EnumFacing.EAST;
			} else if (enumfacing == EnumFacing.EAST && iblockstate3.isFullBlock() && !iblockstate2.isFullBlock()) {
				enumfacing = EnumFacing.WEST;
			}

			worldIn.setBlockState(pos, state.withProperty(FACING, enumfacing), 2);
		}
	}

	@Override
	public IBlockState getStateForPlacement(World worldIn, BlockPos pos, EnumFacing facing, float hitX, float hitY,
			float hitZ, int meta, EntityLivingBase placer) {

Also, how can I cancel the player breaking the block in the onBlockClicked() method?

Why are you trying to draw anything in your tile's update method? Not only is that a different thread, rendering is something that must be done each frame, not each tick. A tick is 1/20 of a second. A frame can literaly be any time value dependant on user's settings, monitor and other things. You must render your things in rederers/render events and nowhere else.

buff.begin(7, buff.getVertexFormat());

getVertexFormat gets the current drawing format. As you are only starting to draw things this getter can't be used. See DefaultVertexFormats for available formats.

Added a TESR.

Changed it to DefaultVertexFormats.POSITION_COLOR.

It doesn't work though.

Do not use GL11 methods directly. Use GlStateManager. Using GL directly messes up with GlStateManager's flags and can screw some things up.

Why are you offsetting the matrix by TE's negative position? That is not a good idea, there is a reason these

7 is GL_QUADS. If you are drawing a line GL_LINES(1) makes much more sense.

This adds raw data to the buffer. Unless you know how to use this you should not be doing that. Use BufferBuilder::pos to specify position, BufferBuilder::color to specify color and BufferBuilder::endVertex to end the current vertex data.

  

Vec3d start = new Vec3d(te.getPos().getX(), te.getPos().getY(), te.getPos().getZ());
Vec3d end = start.addVector(0, 10, 0);
Vec3d posDiff = end.subtract(start);
GlStateManager.pushMatrix();
GlStateManager.glLineWidth(1F);
GlStateManager.disableTexture2D();
BufferBuilder bb = Tessellator.getInstance().getBuffer();
bb.begin(GL11.GL_LINES, DefaultVertexFormats.POSITION_COLOR);
bb.pos(x, y, z).color(1, 1, 1, 1F).endVertex();
bb.pos(posDiff.x, posDiff.y, posDiff.z).color(1, 1, 1, 1F).endVertex();
Tessellator.getInstance().draw();
GlStateManager.enableTexture2D();
GlStateManager.popMatrix();

This is a super-quick(and a bit messy) example that draws the line in 4! calls 2 of which are begin and draw calls. Everything above and below are gl setups/state restoring. I could've even dropped push/pop matrix here as I am not doing anything with the matrix.

 

If you need something more complex than a simple GL line(a line with a texture, more controllable line, rotating line, etc) I suggest you to look at vanilla examples like TileEntityBeaconRenderer or RenderGuardian. The later will need to be adapted to be a TESR but will work just fine.

You can specify the width of the line with GlStateManager::glLineWidth. Quads are better for more control over the rendering process, as they are quads and can be positioned/rotated/textured as you wish, but lines work just fine for simple things. For example vanilla uses LINE_STRIP(which is a variation GL_LINES) do draw the bounding box over the block you are looking at and it works perfect. Lines and quads are just used for different purposes ;)

Thanks, but now how do I change the pos it draws the line to (from the te pos)?

You calculate the vector that points from your TE to the point you want the line to go to and use your start vector + that vector as your end coordinates.

I've had problems with it in the past, mainly by either not rendering anything at all, or by ignoring the line width specified.

Why wouldn't this work? 

			Vec3d start = new Vec3d(te.getPos());
			Vec3d end = new Vec3d(te.BEGIN_LINE_POS);
			GlStateManager.disableTexture2D();
			BufferBuilder bb = Tessellator.getInstance().getBuffer();
			bb.begin(GL11.GL_LINE_STRIP, DefaultVertexFormats.POSITION_COLOR);
			bb.pos(start.x + 0.5, start.y + 0.5, start.z + 0.5).color(0, 1, 1, 1F).endVertex();
			bb.pos(end.x, end.y, end.z).color(0, 1, 1, 1F).endVertex();
			Tessellator.getInstance().draw();
			GlStateManager.enableTexture2D();

Can someone explain?

You are still using your TE's positions as the start of the drawing vector. Use the x/y/z parameters from the draw method.

Your end vector must be a drawing start vector + delta vector of your TE's position and the end position of the line. If your line goes 10 blocks up from your TE it will be [x + 0, y + 10, z + 0].

So.. This? 

			Vec3i start = new Vec3i(x, y, z);
			Vec3d end = new Vec3d(te.BEGIN_LINE_POS.subtract(start));
			GlStateManager.disableTexture2D();
			BufferBuilder bb = Tessellator.getInstance().getBuffer();
			bb.begin(GL11.GL_LINE_STRIP, DefaultVertexFormats.POSITION_COLOR);
			bb.pos(x + 0.5, y + 0.5, z + 0.5).color(0, 1, 1, 1F).endVertex();
			bb.pos(end.x + 0.5, end.y + 0.5, end.z + 0.5).color(0, 1, 1, 1F).endVertex();
			Tessellator.getInstance().draw();
			GlStateManager.enableTexture2D();

It for some reason draws a line from the block to a random place...

Almost.

You should not subtract the start vector as the start vector is the start of the line for rendering. Subtract your TE's position instead - that is the logical start of your line.

Changed it to this.

			Vec3d end = new Vec3d(te.BEGIN_LINE_POS.subtract(te.getPos()));
			GlStateManager.disableTexture2D();
			BufferBuilder bb = Tessellator.getInstance().getBuffer();

			bb.pos(x + 0.5, y + 0.5, z + 0.5).color(0, 1, 1, 1F).endVertex();
			bb.pos(end.x + 0.5, end.y + 0.5, end.z + 0.5).color(0, 1, 1, 1F).endVertex();
			Tessellator.getInstance().draw();
			GlStateManager.enableTexture2D();

Doesn't work.

Looks correct. What is 

8 minutes ago, Kokkie said:

te.BEGIN_LINE_POS

? Is it pointing to fixed coordinates in the world? Is it being synced to the client?

8 minutes ago, Kokkie said:

new Vec3d(te.BEGIN_LINE_POS.subtract(te.getPos()));

=>

te.BEGIN_LINE_POS.subtract(te.getPos()); Vec3d::subtract already returns a new Vec3d object.

 

EDIT: there was an issue in my example. This line:

bb.pos(posDiff.x, posDiff.y, posDiff.z).color(1, 1, 1, 1F).endVertex();

is supposed to be 

bb.pos(x + posDiff.x, y + posDiff.y, z + posDiff.z).color(1, 1, 1, 1F).endVertex();

As you need to specify the end position relative to render coordinates aswell, my bad. Change that line in your code too and it 'should' work provided that everything else is correct.

So, now I want to add a block outline of where it used to be, but it doesn't, also the line doesn't work anymore either.

	}

	private static void drawLine(BlockPos start, BlockPos end, BlockPos pos) {

You can't pass the x/y/z like that. BlockPos rounds anything you pass to it to an integer. For rendering the double precision matters.

If you want to render an outline around a block I recommend not reinventing the wheel and seeing how vanilla does it at RenderGlobal::drawSelectionBoundingBox/RenderGlobal::drawBoundingBox. That method even is public so you can just offset the matrix/BufferBuilder, call it and you are done.

I would also recommend debugging if your methods are called at all.

I now have this. 

public class TESRAutoMiner extends TileEntitySpecialRenderer<TileEntityAutoMiner> {

		}
	}
	
	@Override
	public boolean isGlobalRenderer(TileEntityAutoMiner te) {
		return true;
	}
}
public class AMUtils {
	public static void drawLineMiddle(BlockPos start, BlockPos end, double x, double y, double z) {
		drawLine(start, end, x + 0.5, y + 0.5, z + 0.5);
	}

	private static void drawLine(BlockPos start, BlockPos end, double x, double y, double z) {
		Vec3d start1 = new Vec3d(start);
		Vec3d end1 = new Vec3d(end);
		Vec3d posDiff = end1.subtract(start1);

		Tessellator.getInstance().draw();
		GlStateManager.enableLighting();
		GlStateManager.enableTexture2D();
		GlStateManager.popMatrix();
	}

	public static void drawBox(BlockPos block, double x, double y, double z) {
		double minX = block.getX();
		double minY = block.getY();
		double minZ = block.getZ();
		double maxX = block.getX() + 1;
		double maxY = block.getY() + 1;
		double maxZ = block.getZ() + 1;
		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);
		RenderGlobal.drawBoundingBox(minX, minY, minZ, maxX, maxY, maxZ, 1, 0, 0, 1);
        GlStateManager.depthMask(true);
        GlStateManager.enableTexture2D();
        GlStateManager.disableBlend();
	}
}

It renders the line, but doesn't render the box.

Before drawing the box using RenderGlobal's method you must offset your BufferBuilder or GL's matrix to where you actually want to render the box at. RenderGlobal renders a [minX, minY, minZ] to [maxX, maxY, maxZ] box. You are currently offseting by x/y/z of the BlockPos in the world, and you must offset by render x/y/z + delta vector of the BlockPos in the world and your TE's pos, similar to how you draw a line.

I've sort of got it working, it only draws 4 lines instead of 12... Only the top Z lines and bottom X lines. 

public class TESRAutoMiner extends TileEntitySpecialRenderer<TileEntityAutoMiner> {
	@Override
	public void render(TileEntityAutoMiner te, double x, double y, double z, float partialTicks, int destroyStage,

		if (te.DRAW_LINE) {
			AMUtils.drawLineMiddle(te.getPos(), te.BEGIN_LINE_POS, x, y, z);
			AMUtils.drawBox(te.getPos(), te.BEGIN_LINE_POS, x, y, z);
		}
	}
	
	@Override
	public boolean isGlobalRenderer(TileEntityAutoMiner te) {
		return true;
	}
}
public class AMUtils {
	public static void drawLineMiddle(BlockPos start, BlockPos end, double x, double y, double z) {
		drawLine(start, end, x + 0.5, y + 0.5, z + 0.5);
	}

	private static void drawLine(BlockPos start, BlockPos end, double x, double y, double z) {
		Vec3d start1 = new Vec3d(start);
		Vec3d end1 = new Vec3d(end);
		Vec3d posDiff = end1.subtract(start1);
		GlStateManager.pushMatrix();
		GlStateManager.glLineWidth(2F);
		GlStateManager.disableTexture2D();
		GlStateManager.disableLighting();
		BufferBuilder bb = Tessellator.getInstance().getBuffer();
		bb.begin(GL11.GL_LINES, DefaultVertexFormats.POSITION_COLOR);
		bb.pos(x, y, z).color(1, 0, 0, 1F).endVertex();
		bb.pos(x + posDiff.x, y + posDiff.y, z + posDiff.z).color(1, 0, 0, 1F).endVertex();
		Tessellator.getInstance().draw();
		GlStateManager.enableLighting();
		GlStateManager.enableTexture2D();
		GlStateManager.popMatrix();
	}

	public static void drawBox(BlockPos start, BlockPos end, double x, double y, double z) {
		Vec3d start1 = new Vec3d(start);
		Vec3d end1 = new Vec3d(end);
		Vec3d posDiff = end1.subtract(start1);
		double minX = x + posDiff.x;
		double minY = y + posDiff.y;
		double minZ = z + posDiff.z;
		double maxX = x + posDiff.x + 1;
		double maxY = y + posDiff.y + 1;
		double maxZ = z + posDiff.z + 1;
		GlStateManager.pushMatrix();
		GlStateManager.glLineWidth(2F);
		GlStateManager.disableTexture2D();
		GlStateManager.disableLighting();
		BufferBuilder bb = Tessellator.getInstance().getBuffer();
		bb.begin(GL11.GL_LINES, DefaultVertexFormats.POSITION_COLOR);

		Tessellator.getInstance().draw();
		GlStateManager.enableLighting();
		GlStateManager.enableTexture2D();
		GlStateManager.popMatrix();
	}
}

Also, how can I make it so it renders even if you can't see the block, like beacons?

If you look at RenderGlobal::drawBoundingBox method you will see that it uses a different GL mode of 3, which is GL_LINE_STRIP. The difference is that LINES requires you to specify a beginning an an end for each new line you draw, where LINE_STRIP assumes that the end of the last line is the beginning of the new one. You are not using the correct GL mode here.

You know they say that a good question already contains an answer? This is one very good question. You know that there is a block in game that does X. The next logical step - lookup how it does X in it's code. In your case you need to override TileEntity::getRenderBoundingBox and possibly TileEntity::getMaxRenderDistanceSquared if you want your tile to be drawn more than 64 blocks away.

This is something you will need to use QUADS for. You need to specify 4 vertices per quad(4 corners) and 6 quads(faces) make up a cube if positioned correctly. The ordering(CW vs CCW) also matters. You might need to experiment with it a bit to get the desired results. Vanilla uses models to abstract from direct rendering so I can't quite provide an example of direct rendering here.
