Custom Bars, Panes & Walls

This page explains how to add support for custom bars, panes, and walls — including behavior such as attachment, connectivity, and rendering between connected blocks.

Making Bars Compatible

By adding your custom bars to the bars block tag, most behavior will work automatically.

• All blocks in the bars tag are breakable with a pickaxe.
• Bars will automatically attach to other panes, bars, and walls.
• The rendering logic skips rendering between connected blocks if both are in the bars tag.

This ensures high compatibility with other custom bars that also use this tag.

Attaching to Panes & Bars

Blocks added to the attaches_to_panes_and_bars block tag will visually connect to glass panes and iron bars.

Connecting to Walls

Blocks added to the connects_to_wall block tag will visually connect to walls.

Rendering Panes & Bars

The rendering logic has been updated to skip rendering between connected blocks if both blocks are in the same pane-related tag.
