Panes/bars in vanilla share models & collisions, I'm fairly sure, just changing textures. I want to add in my own variant, a type of iron bars (made of a custom ingot).

 

My current thinking of my options are:

1. Override addCollisionBoxToList and return all the collision boxes depending on the current blockstate. (This will probably be like 200 lines of coordinates and state checking, bleugh)

2. Find some way to copy the functionality from native panes/bars

 

Does anyone know of a way to do this? If I have to do the first option I think I might just skip out on this idea haha

You can extend BlockPane to make your block act like a pane or iron bar. Then also copy the blockstate and model files and adapt properly.
