1.19 Detect if the player is looking at the sun?


Recommended Posts

The short answer is you probably can't in general because it will depend on if/how mods modify the sky rendering.


Assuming vanilla rendering, try this which (I think?) shows the player's view vector and a calculation of the vector to the sun at the top of the screen.

@Mod.EventBusSubscriber(modid = MODID, bus = Bus.MOD, value = Dist.CLIENT)
public class ModClientEvents {

    public static void registerOverlay(RegisterGuiOverlaysEvent event) {

        event.registerAboveAll("view_sun", (gui, poseStack, partialTick, screenWidth, screenHeight) -> {

            Minecraft minecraft = Minecraft.getInstance();
            Entity entity = minecraft.cameraEntity;
            Level level = minecraft.level;
            float sunAngle = level.getSunAngle(partialTick) + (float) Math.PI / 2; // use -pi/2 for the moon
            Vec3 view = entity.getViewVector(1.0f);
            Vec3 sun = new Vec3(Math.cos(sunAngle), Math.sin(sunAngle), 0f);
            String msg = String.format(Locale.ROOT, "%.3f / %.3f / %.3f / %.3f / %.3f / %.3f / %.3f", sunAngle, view.x, view.y, view.z, sun.x, sun.y, sun.z);

            gui.setupOverlayRenderState(true, false, null);
            Font font = minecraft.font;
            GuiComponent.fill(poseStack, 1, 1, 3 + font.width(msg), 1 + font.lineHeight, 0x6FAFAFB0);
            font.draw(poseStack, msg, 2, 2, 0xE0E0E0);


You can probably use this as a starting point of your calculation to see if the 2 vector's components are close in value, or maybe something more complicated (e.g. taking into account moon phases).

I would guess you also want to do some kind of ray trace - entity.pick() - to see if there is a block/fluid or entity blocking the sun, and also check the weather. 🙂

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.
