EnderEyeGlow

This modification significantly simplifies the search for the End Fortress by adding a glow effect to thrown Eyes of Ender. When you throw an eye, it becomes outlined with a glow similar to the glowing effect, making it easy to track its trajectory and not lose sight of it.

Additionally, the mod creates particles when the item falls to the ground, making the search process even more visual. When installing the compatible ColoredGlowLib library, you gain the ability to customize the glow color to your preference.

All features can be flexibly configured through the configuration file. Access to settings requires the ModMenu and YACL mods, which provide a convenient interface for managing parameters.

Vanilla Alternative

If you prefer not to install mods, a similar effect can be achieved using a command block. Set up a repeating command block in an active state with the following command:

execute as @e[type=minecraft:eye_of_ender] run data merge entity @s {Glowing:1}
