Draw a line on blocks at specific coordinates (1.16X)

Recommended Posts

I have a path finding class, that gives coordinates when called but because i'm very new to forge, games and rendering i have no idea how to implement this (Client side) into the game. 
I don't care if its a line or glowing blocks or something else. I just want an indicator for where i have to go.
My mod has a 1.16 and a 1.8 version, but the 1.16 is more important for me so support in that version would be appreciated.

Thanks in advance

This is some really old code, but most of the logic wouldn't have changed as a result of newer minecraft versions, though some of the wrapper classes have.

Basically you just need to find a line between two points (trivial) find a perpendicular line between that one and vertical (or along the camera's view vector), which is a dot product, then use the resulting values to find the four corners of a quad those two lines represent, and add that quad to the render buffer.

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.

    • For anyone looking here in the future, I never solved this problem, but I found a workaround by simply ungrabbing the mouse, preventing mouse movement.
