@SubscribeEvent public void onKeyInputEvent(InputEvent.Key event) { if (Minecraft.getInstance().options.keyForward.isDown()) { // ... } } or if (Minecraft.getInstance().player.input.up) { // ... }

Thanks, works like a charm!

Thanks, but I don't need parameter in vanilla classes, I need parameters in my own mod classes. The reason for this I developed simple scripting language I integrated in my mod, and I want to automatically build API reference by using reflection over API classes. Parameter names can be good to understand what method is doing.

I am using IntelliJ (not sure if it matters). How can I add java compiler parameter to "runClient" configuration and "build" gradle task? I want to add harmless "-parameters" flag, so class files inside jar will contain original parameter names.

Working code for 1.19: Vec3 view = mc.gameRenderer.getMainCamera().getPosition(); RenderSystem.depthMask(false); RenderSystem.disableCull(); RenderSystem.enableBlend(); RenderSystem.defaultBlendFunc(); RenderSystem.disableTexture(); GL11.glEnable(GL11.GL_LINE_SMOOTH); GL11.glDisable(GL11.GL_DEPTH_TEST); var tesselator = Tesselator.getInstance(); var buffer = tesselator.getBuilder(); buffer.begin(VertexFormat.Mode.DEBUG_LINES, DefaultVertexFormat.POSITION_COLOR); buffer.vertex(0, 0, 0).color(1f, 1f, 1f, 1f).endVertex(); buffer.vertex(100, 200, 100).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().copy(), shader); matrix.popPose(); VertexBuffer.unbind();

In 1.18 I used this code, but it no longer works. Could you give me some hints or example from other mods source code? I know I can look into Minecraft source, but they use VertexFormat.Mode.LINES and vertex format with normal. var tesselator = Tesselator.getInstance(); var buffer = tesselator.getBuilder(); buffer.begin(VertexFormat.Mode.DEBUG_LINES, DefaultVertexFormat.POSITION_COLOR); buffer.vertex(x1, y1, z1).color(1f, 1f, 1f, 1f).endVertex(); buffer.vertex(x2, y2, z2).color(1f, 1f, 1f, 1f).endVertex(); buffer.end(); vertexBuffer.upload(buffer); RenderSystem.depthMask(false); RenderSystem.disableCull(); RenderSystem.enableBlend(); RenderSystem.defaultBlendFunc(); RenderSystem.disableTexture(); GL11.glEnable(GL11.GL_LINE_SMOOTH); GL11.glEnable(GL11.GL_DEPTH_TEST); PoseStack poseStack = event.getPoseStack(); poseStack.pushPose(); poseStack.translate(-view.x, -view.y, -view.z); var shader = GameRenderer.getPositionColorShader(); vertexBuffer.drawWithShader(poseStack.last().pose(), event.getProjectionMatrix().copy(), shader); poseStack.popPose(); RenderSystem.depthMask(true); RenderSystem.disableBlend(); RenderSystem.enableCull(); RenderSystem.enableTexture();

It is simple task when View Bobbing is disabled. In RenderWorldLastEvent I do this: Vector3d view = Minecraft.getInstance().gameRenderer.getMainCamera().getPosition(); MatrixStack stack = event.getMatrixStack(); stack.translate(-view.x, -view.y, -view.z); GL11.glPushMatrix(); RenderSystem.multMatrix(stack.last().pose()); double centerX = view.x; double centerY = view.y; double centerZ = view.z; double drawBeforeCameraDist = 1; double pitch = (mc.player.xRot) * Math.PI / 180; double yaw = (mc.player.yRot) * Math.PI / 180; centerX -= Math.sin(yaw) * Math.cos(pitch) * drawBeforeCameraDist; centerZ += Math.cos(yaw) * Math.cos(pitch) * drawBeforeCameraDist; centerY -= Math.sin(pitch) * drawBeforeCameraDist; But when I enabled View Bobbing, the center point starts moving in half-circle trajectory. I looked into GameRenderer class, bobView method. It calculates few float values and applies them to MatrixStack. I don't know if I can use this matrix (it comes in RenderWorldLastEvent), so I copied code from bobView and started experimentation. This is the best I can get: // omitted same lines from my first example double centerX = view.x; double centerY = view.y; double centerZ = view.z; double deltaXRot = 0; double deltaZRot = 0; double translateX = 0; double translateY = 0; if (mc.options.bobView && mc.getCameraEntity() instanceof PlayerEntity) { PlayerEntity playerentity = (PlayerEntity)mc.getCameraEntity(); float f = playerentity.walkDist - playerentity.walkDistO; float f1 = -(playerentity.walkDist + f * event.getPartialTicks()); float f2 = MathHelper.lerp(event.getPartialTicks(), playerentity.oBob, playerentity.bob); translateX = (double)(MathHelper.sin(f1 * (float)Math.PI) * f2 * 0.5F); translateY = (double)(-Math.abs(MathHelper.cos(f1 * (float)Math.PI) * f2)); deltaZRot = MathHelper.sin(f1 * (float)Math.PI) * f2 * 3.0F; deltaXRot = Math.abs(MathHelper.cos(f1 * (float)Math.PI - 0.2F) * f2) * 5.0F; } double drawBeforeCameraDist = 1; double yaw = (mc.player.yRot) * Math.PI / 180; double pitch = (mc.player.xRot + deltaXRot) * Math.PI / 180; centerY -= translateY; centerX += translateX * Math.cos(yaw); centerZ += translateX * Math.sin(yaw); centerX -= Math.sin(yaw) * Math.cos(pitch) * drawBeforeCameraDist; centerZ += Math.cos(yaw) * Math.cos(pitch) * drawBeforeCameraDist; centerY -= Math.sin(pitch) * drawBeforeCameraDist; Now center point doesn't jump to the right and left on the screen. And it doesn't jump up and down, but only if I look straight forward. As pitch angle goes far from 0 (either to -90 or 90), center point jumps harder up and down. Is my approach right? Or should I learn about MatrixStack and try to use it?
