After some research I've found RenderLevelStageEvent which fits my needs.

I've found the solution. My problem(s) were an invalid translation + I called it inside the wrong event. Working code for 1.20.2: SubscribeEvent public static void onRenderLayerPost(RenderLevelStageEvent event) { Vec3 view = Minecraft.getInstance().gameRenderer.getMainCamera().getPosition(); var tesselator = Tesselator.getInstance(); var buffer = tesselator.getBuilder(); VertexBuffer vertexBuffer = new VertexBuffer(VertexBuffer.Usage.STATIC); buffer.begin(VertexFormat.Mode.DEBUG_LINES, DefaultVertexFormat.POSITION_COLOR); buffer.vertex(0, 0, 0).color(1f, 1f, 1f, 1f).endVertex(); buffer.vertex(10, 10, 10).color(1f, 1f, 1f, 1f).endVertex(); vertexBuffer.bind(); vertexBuffer.upload(buffer.end()); PoseStack matrix = event.getPoseStack(); matrix.pushPose(); matrix.translate(-view.x, -view.y, -view.z); var shader = GameRenderer.getPositionColorShader(); vertexBuffer.drawWithShader(matrix.last().pose(), event.getProjectionMatrix(), shader); matrix.popPose(); VertexBuffer.unbind(); } Most of the code is from this post:

As the title says. In the newer versions this event is not supported anymore. What are some decent alternatives? (I'm looking to draw lines in the world)

Thanks, yes I did - it brought me to LevelRenderer.java, which has some great examples. I tried applying some of what Mojang did there, but without success. Here is my code: I try to plot a vertical line close to world coordinates 0, 0, 0 but cannot see it in game, "rendering" is being printed inside the console. I really don't know what I'm missing, I've been looking at code examples for days now - slowly it becomes a bit frustrating.

Every other implementation I've found used BufferBuilder. I'm not sure if it would be a clean solution to project 3D line(s) that are bound to world coordinates to a 2D GUI. If you still suggest using IGuiOverlay for that I'll give it a try. This would also create problems when using the 3rd person cam (F5), because the ray could be theoretically be casted from the back of the player.

I'd like to visualize a ray that I cast from a player. To archieve this, I need to be able to draw a line. Currently, I am using this code for testing purposes, but I cannot see any line drawn around x=0 y=0 z=0: @SubscribeEvent public static void onClientTick(TickEvent.ClientTickEvent event) { // Only call code once as the tick event is called twice every tick if (event.phase == TickEvent.Phase.END) { if(MEASUREMENT_MANAGER.isCurrentlyMeasuring()) { Tesselator tesselator = Tesselator.getInstance(); BufferBuilder bufferBuilder = tesselator.getBuilder(); Color c = new Color(1, 0, 0, 0.4f); bufferBuilder.begin(VertexFormat.Mode.LINES, DefaultVertexFormat.POSITION_COLOR); bufferBuilder.vertex(0, 0, 0).color(c.getRed(), c.getGreen(), c.getBlue(), c.getAlpha()).endVertex(); bufferBuilder.vertex(0, 2, 2).color(c.getRed(), c.getGreen(), c.getBlue(), c.getAlpha()).endVertex(); tesselator.end(); } } } There have been many implementations in lower versions, but I could not find any for 1.20.2. What I've found, however, is this implementation on GitHub: https://github.com/cabaletta/baritone/blob/e183dcba1707c991fea1ba55be052dc3ee5d71a6/src/main/java/baritone/utils/IRenderer.java#L149 This also did not work for me. Any help would be appreciated.

I am having a similar problem. Could you solve it?
