The environment consists of tiles, liquids, walls, and stationary objects. Players cannot control or interact with most environmental aspects, but many liquids affect players in various ways.
Liquids are defined as tiles that cause sprites to be partially submerged when on the tile. Most liquids decrease walking speed.
Walls are solid tiles that prevent both players and enemies from moving past them. However, the player may teleport over walls (either by teleporting to other players, or short-range by using Prisms or the Cloak of the Planewalker.)
Stationary Objects are not considered tiles and are generally used as flavor. Players, enemies, and projectiles can pass through some stationary objects.
Obstacles are stationary objects which prevent entities from passing through them. However, certain projectiles can pass through obstacles. One example of an obstacle is a rock, commonly found in the Mountains.
