For each pair of entities where BOTH have =#:solid? #t=, if they overlap: if one has =#:immovable? #t=, only the other entity is displaced (its velocity on that axis is zeroed). For movable vs immovable, separation prefers **vertical** resolution when the movable’s center is still **above** the immovable’s center (typical landing on a platform), so narrow horizontal overlap does not shove the mover sideways through the edge. Otherwise the shallow overlap axis is used. If both are immovable, the pair is skipped. If neither is immovable, the two bodies are pushed apart along the smaller overlap axis and their velocities on that axis are set to ±1. Entities without =#:solid?= or with =#:solid? #f= are skipped. Returns a new entity list with collisions resolved. |
