Context
I'm trying to render outlines of specific blocks that are visible through walls, i've tried multiple times to use the raw opengl libraries, but i get the same issue everytime, no context specified. I've tried looking through the documentation, and various forge-alternatives. I've attempted to use pre-made libraries to render the boxes, it does it successfully but the offset is not at the block, and doesn't change no matter where i move.
I've been researching and apparently i need to use the tesselator and the built-in bufferbuilder, i'd love some guidance (and|or) clarification on what i should use.
Thanks!
