This would not be to laggy as it would only be a few certain blocks that are I assume keeping a multiblock from constructing? Or something similar. You should make a static Map of BlockPos linked to the BlockPos of your TileEntity then after a certain amount of time has passed remove the ones linked to your TileEntites BlockPos. The rendering should then be done in the Event mentioned prior. Drawing as mentioned prior as well.

Is there any good tutorial for drawing lines on the screen in MC 1.10 with Tessellator?

Which args should i use in the Vertexbuffer.begin(, ) for just drawing (red) lines?

Largely speaking, you need to look up how to use OpenGL / GL11.  VertexBuffer's second paramter is the same one passed to GL11.Begin() (which typically you want to use GL11.GL_QUADS).  Last time I tried using lines I had trouble.

And the other arg in VertexBuffer.begin(int glMode, VertexFormat format)??

And the other arg in VertexBuffer.begin(int glMode, VertexFormat format)??

Try DefaultVertexFormat...

And which one exactly?

WorldRenderer has become VertexBuffer and instead of addVertex it is the way diesieben said. You also must call vb.startDrawing(glnum, DefaultVertexFormats...) mess around with that last var because i do not know what it would be in this case.

And which one exactly?

Hopefully the last Question in this Topic:

Actually I get almost everything running, just the lines act strange depending on the direktion the player looking.

 

Thats not what I want

This is what I want

 

 

Does anybody know how to fix this?

Could you post your current code?

public class MultiAssemblerTESR extends TileEntitySpecialRenderer<TileEntityMultiAssembler>
{
@Override
public void renderTileEntityAt(TileEntityMultiAssembler te, double x, double y, double z, float partialTicks, int destroyStage) 
{

        int teposX = te.getPos().getX();
        int teposY = te.getPos().getY();
        int teposZ = te.getPos().getZ();
        Map list = te.getBlocksWithMarkersList();
	Entity entity = this.rendererDispatcher.entity;
	double distance = te.getDistanceSq(entity.posX, entity.posY, entity.posZ);
    if (distance < 100.0 && !list.isEmpty()) 
    {
    	
    	 Iterator iterator = list.entrySet().iterator();
         Entry entry;
         do
         {
             entry = (Entry)iterator.next();
             BlockPos actualpos = (BlockPos) entry.getKey();
             drawCubeWithCrossesAtPos(x, y, z, actualpos.getX() - teposX, actualpos.getY() - teposY, actualpos.getZ() - teposZ);

Does this actually give you the correct position?

actualpos.getX() - teposX, actualpos.getY() - teposY, actualpos.getZ() - teposZ

Why not just pass the BlockPos#getX() ect?

 

*Edit Also only call tessellator.draw() once at the end.

Because I render more than 1 Block and I need to set their position referenced to the TE

Because I render more than 1 Block and I need to set their position referenced to the TE

te.getPos().getX() == x, te.getPos().getY() == y, and te.getPos().getZ() == z.

If so you would no do this

 

GL11.glTranslated(x + addx, y + addy, z + addz);

 

Just some math

x + (actualpos.getX() - teposX), y + (actualpos.getY() - teposY), and z + (actualpos.getZ() - teposZ) should = actualpos.getX(), actualpos.getY(), and actualpos.getZ()

ok, just some unnecessary math, but this would fix my rendering problem

I don't think the math would, but did you try my second suggestion. But amended to also only calling begin once.

Don´t work, but thank you a lot

I think, but I am not sure, that you are running into Z-Fighting: the lines you are drawing occur in the same z-depth (distance from the camera) as the objects you're drawing them "over" so the GPU can't correctly sort their order.

is there anything I can do to "sort" it?

Rather than drawing exactly at the coordinates (e.g.

(1, 1, 1

) draw slightly offset (e.g.

1.001, 1.001, 1.001

).  You'll want to draw larger than the block and you don't care if that direction is towards or away from the camera (if it's away, then it's behind, and won't draw anyway).

its my own block, it is a TESR and it drow over all type of blocks

I'm not sure you understood what Draco was saying.

// Instead of this
		worldRenderer.pos(0, 0, -0.001).endVertex();
		worldRenderer.pos(1, 1, -0.001).endVertex();
		worldRenderer.pos(1, 0, -0.001).endVertex();
		worldRenderer.pos(0, 1, -0.001).endVertex();
// Do this
		worldRenderer.pos(-0.001, -0.001, -0.001).endVertex();
		worldRenderer.pos(1.001, 1.001, -0.001).endVertex();
		worldRenderer.pos(1.001, -0.001, -0.001).endVertex();
		worldRenderer.pos(-0.001, 1.001, -0.001).endVertex();

Now I get it and it works fine, thanks a lot!
