CollisionsCheckRule

Rule that validates placement based on collision detection. This rule checks for physics collisions at indicator positions and validates based on the pass_on_collision setting: - false (default): Placement FAILS if collision detected ("must have clear space") - true: Placement FAILS if NO collision detected ("must overlap with existing objects")

Name	Kind	Summary
pass_on_collision	Property	Controls collision validation behavior: - false: Rule PASSES when no collision (placement requires clear space) - true: Rule PASSES when collision detected (placement requires overlap) Common use cases: - false: Building placement (needs empty space) - true: Attachment mechanics (must connect to existing structures)
collision_mask	Property	Physics layers to scan for collisions.
