A truss is a single brick that is climbable. At its smallest, is not scripted to climb, and doesn't require more than 2 parts. The shortest size it can be is 2x2x2. Builders can change the designs, and perform most things a part can. It's resizeable, colorable, and one can also change its material. If a truss is stacked or resized, it can be climbable.
Trivia
- Players used to be able to quickly climb trusses by repeatedly tapping the space bar while climbing. However, this can no longer be done (as the player now simply gets off the truss) due to recent physics and animation updates.
