[1.14.4] Custom rendering

Recommended Posts

You'd have to offset by the player's eye height too, rather than just position.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

Thanks and another question, so I am interpolating players last and current position with partialTicks, it works but when I am moving its is rendering it a little bit behind the actual position. I think it is because of usage of lastPos but there must be some way to fix it.

Post your code.

GlStateManager.pushMatrix();
GlStateManager.disableTexture();
GlStateManager.disableLighting();
GlStateManager.disableDepthTest();
GlStateManager.enableBlend();
GlStateManager.blendFuncSeparate(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA, 1, 0);
GlStateManager.lineWidth(1);

Vec3d renderPos = Utils.getInterpolatedEyePos(MC.player, event.getPartialTicks());
RenderEvent renderEvent = new RenderEvent(GeometryTessellator.getInstance(), renderPos, event.getPartialTicks());
renderEvent.resetTranslation();
MinecraftForge.EVENT_BUS.post(renderEvent);

GlStateManager.lineWidth(1);
GlStateManager.disableBlend();
GlStateManager.enableDepthTest();
GlStateManager.enableLighting();
GlStateManager.enableTexture();
GlStateManager.popMatrix();

GeometryTesselattor extends Tesselator and adds some helper functions.

RenderEvent.resetTranslation() translates tesselators buffer by renderPos. (Passed in constructor)

Utils.getInterpolatedEyePos():

public static Vec3d getInterpolated(Entity entity, double x, double y, double z) {
    return new Vec3d((entity.posX - entity.lastTickPosX) * x, (entity.posY - entity.lastTickPosY) * y, (entity.posZ - entity.lastTickPosZ) * z);
}
public static Vec3d getInterpolated(Entity entity, double ticks) {
    return getInterpolated(entity, ticks, ticks, ticks);
}
public static Vec3d getInterpolatedPos(Entity entity, double ticks) {
    return new Vec3d(entity.posX, entity.posY, entity.posZ).add(getInterpolated(entity, ticks)) ;
}
public static Vec3d getInterpolatedEyePos(Entity entity, double ticks) {
    return getInterpolatedPos(entity, ticks).add(0, entity.getEyeHeight(), 0);
}

And when I Subscribe to that event is just adds some vertices to buffer and calls tesselators draw method.

If you can help me it would be awesome.

I have a similar problem. When I draw something in world on RenderWorldLastEvent, everything works fine except when player sneaks.

 

 

And here is my code.

 

        @SubscribeEvent
        public static void onRenderWorldLast(RenderWorldLastEvent event) {
            BlockRenderer.renderBlockOutline(event.getPartialTicks()); // XXX render one block at 1, 1, 1 for testing
        }

 

    public static void renderBlockOutline(float partialTicks) {
        ClientPlayerEntity playerEntity = Minecraft.getInstance().player;
        double x = playerEntity.lastTickPosX + (playerEntity.posX - playerEntity.lastTickPosX) * partialTicks;
        double y = playerEntity.lastTickPosY + (playerEntity.posY - playerEntity.lastTickPosY) * partialTicks;
        double z = playerEntity.lastTickPosZ + (playerEntity.posZ - playerEntity.lastTickPosZ) * partialTicks;

        //LogManager.getLogger().info(playerEntity.getEyePosition(partialTicks));
        //Vec3d eyePos = playerEntity.getEyePosition(partialTicks);
        //Vec3d eyePos = Minecraft.getInstance().getRenderViewEntity().getEyePosition(partialTicks);

        GlStateManager.pushMatrix();

        //GlStateManager.translated(-eyePos.x, -eyePos.y, -eyePos.z);
        GlStateManager.translated(-x, -y - playerEntity.getEyeHeight(), -z);
        GlStateManager.translated(-9, 63, 6);

        GlStateManager.disableCull();
        GlStateManager.disableDepthTest();
        GlStateManager.disableTexture();

        GlStateManager.color4f(1, 1, 1, 1);
        //GlStateManager.lineWidth(1);

        Tessellator tessellator = Tessellator.getInstance();
        BufferBuilder bufferBuilder = tessellator.getBuffer();

        bufferBuilder.begin(GL11.GL_QUADS, DefaultVertexFormats.POSITION);

        bufferBuilder.pos(0, 0, 0).endVertex();
        bufferBuilder.pos(1, 0, 0).endVertex();
        bufferBuilder.pos(1, 0, 1).endVertex();
        bufferBuilder.pos(0, 0, 1).endVertex();

        bufferBuilder.pos(0, 1, 0).endVertex();
        bufferBuilder.pos(1, 1, 0).endVertex();
        bufferBuilder.pos(1, 1, 1).endVertex();
        bufferBuilder.pos(0, 1, 1).endVertex();

        tessellator.draw();

        GlStateManager.enableDepthTest();
        GlStateManager.enableTexture();

        GlStateManager.popMatrix();
    }

This means the y value not all of the values as it seems you were doing.

Can you show me what you mean by it being behind the actual position?
