i'm on 1.21.10
followed the documentation: https://docs.fabricmc.net/develop/rendering/world
found out WorldRenderEvents has been removed, and it is advised to use mixin instead (https://fabricmc.net/2025/09/23/1219.html)
i'm a bit lost as to how to go from here. something as simple as drawing a line between two vertices in the world would help, thanks in advance.
