Rust Base Planner

What the Planner Does and Doesn't Model

• Squares and true equilateral triangles, 3 m a side as in the game. A new tile snaps across the nearest free edge of one already placed, so triangles and squares meet at the game's own angles; on open ground squares sit on a 3 m grid.
• Stability is a model of the game's, not the game's own sum. We measured the game's stability on 302blocks in test structures on our own server, stairs, ramps and half walls included, and fitted the planner to them: within 5 percentage points on 296 of the 301 it can rebuild. The game's figure depends on the order pieces went up, so treat ours as a guide. Pieces under 5%, which the game destroys, are flagged.
• Half walls and low walls measured the same as a full wall of their grade when we blew them up, so a route through one is priced at the wall figure. Whether a player can climb over one instead is decided in the game client, which we can't read, so those steps say it may cost nothing.
• Ramps stand on a square floor or foundation. In the game a ramp rises 0.76m across the tile and holds 70% of the tile's stability; it is costed as the game's ramp block and doesn't block the raid path.
• Building privilege reaches 16m from any block of a base that has a tool cupboard, measured from the block's bounds. That is the game's own rule, read from its code and checked on our server. Turn on Privilege to see the zone.
• Every block is costed at what the game charges for that shape and grade, from our dump of the game's building blocks (build 2634.289.1): a floor, roof or frame is half a wall, a doorway or window 70%, rounded up. The build cost includes the twig each block is placed as.
• A roof, a stair and a floor of any shape are broken at the same-grade floor figure. Rust uses one damage table for a wall and the floor of the same material, and the other block shapes are treated the same way here. Stairs and empty frames are openings: the raid path walks through them for nothing.
• Inserts (bars, glass, embrasures, hatches and grills, square or triangle) are priced from what we measured by setting off the game's own explosives against each one on our server. Where a piece is identical to a wall or door in health and armour (wooden bars and a wooden wall; a hatch, a grill and a sheet metal door), it takes that piece's figure for explosive 5.56 and incendiary rockets, which that method can't measure. Where it has no twin, the path marks the step †.
• Explosives cost the same from either side of a wall. The game's soft-side rule only applies to hits that know which piece they struck, and an explosion never does. The soft side matters for melee and guns: a stone wall's soft side takes about a tenth of the pickaxes its hard side does.
• Deployables (furnaces, boxes, workbenches, bags, turrets, traps) are placed on tiles and costed from their craft recipes, listed apart from the block total; they add nothing to upkeep. The raid path goes through walls, doors, windows, hatches and ceilings and doesn't model ladders, turrets, traps or anyone shooting back — a turret in the plan is furniture, not a defence.
