You shouldn't use ID's...

Thanks, it works

Do I have to reset the lightmap after rendering?

It can't be, I disable the lighting..

How can I remove or disable the color being darkened by idk what? Like, I set it to red but it is a dark color red instead of just bright red. Also, it becomes bright red when I don't look at the block and are a few blocks away from it.

Now, how would I render a cube? (6 squares)

Thanks!

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, float alpha) { 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); RenderGlobal.drawBoundingBox(bb, minX, minY, minZ, maxX, maxY, maxZ, 1, 0, 0, 1); 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?

I now have this. public class TESRAutoMiner extends TileEntitySpecialRenderer<TileEntityAutoMiner> { @Override public void render(TileEntityAutoMiner te, double x, double y, double z, float partialTicks, int destroyStage, float alpha) { if (te.DRAW_LINE) { AMUtils.drawLineMiddle(te.getPos(), te.BEGIN_LINE_POS, x, y, z); AMUtils.drawBox(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 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.

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. public class TESRAutoMiner extends TileEntitySpecialRenderer<TileEntityAutoMiner> { @Override public void render(TileEntityAutoMiner te, double x, double y, double z, float partialTicks, int destroyStage, float alpha) { if (te.DRAW_LINE) { BlockPos pos = new BlockPos(x, y, z); AMUtils.drawLineMiddle(te.getPos(), te.BEGIN_LINE_POS, pos); AMUtils.drawBox(te.BEGIN_LINE_POS, pos); } } } public class AMUtils { public static void drawLineMiddle(BlockPos start, BlockPos end, BlockPos pos) { BlockPos start1 = start.add(0.5, 0.5, 0.5); BlockPos end1 = end.add(0.5, 0.5, 0.5); drawLine(start1, end1, pos); } private static void drawLine(BlockPos start, BlockPos end, BlockPos pos) { 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(pos.getX(), pos.getY(), pos.getZ()).color(0, 1, 0, 1F).endVertex(); bb.pos(pos.getX() + posDiff.x, pos.getY() + posDiff.y, pos.getZ() + posDiff.z).color(0, 1, 0, 1F).endVertex(); Tessellator.getInstance().draw(); GlStateManager.enableLighting(); GlStateManager.enableTexture2D(); GlStateManager.popMatrix(); } public static void drawBox(BlockPos block, BlockPos pos) { drawLine(block, block.add(1, 0, 0), pos); drawLine(block, block.add(0, 1, 0), pos); drawLine(block, block.add(0, 0, 1), pos); drawLine(block.add(1, 0, 0), block.add(1, 1, 0), pos); drawLine(block.add(1, 0, 0), block.add(1, 0, 1), pos); drawLine(block.add(0, 1, 0), block.add(1, 1, 0), pos); drawLine(block.add(0, 1, 0), block.add(0, 1, 1), pos); drawLine(block.add(0, 0, 1), block.add(1, 0, 1), pos); drawLine(block.add(0, 0, 1), block.add(0, 1, 1), pos); drawLine(block.add(1, 1, 0), block.add(1, 1, 1), pos); drawLine(block.add(1, 0, 1), block.add(1, 1, 1), pos); drawLine(block.add(0, 1, 1), block.add(1, 1, 1), pos); } }

Thanks, it works!

I think it uses metadata.

You can get the type from the tileentity

Changed it to this. Vec3d start = new Vec3d(x, y, z); Vec3d end = new Vec3d(te.BEGIN_LINE_POS.subtract(te.getPos())); 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(); Doesn't work.

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...

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?

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

Added a TESR. Changed it to DefaultVertexFormats.POSITION_COLOR. It doesn't work though.

Show your code.

Ah ok, I thought it might have been for a cheat which aren't supported here. Just making sure
