Class DragManager

Namespace

GridPlacement.GDScript

Assembly

MoonBark.GridPlacement.GDScript.dll

Self-contained drag manager for tile-based drag operations.\n\nReads confirm_build input action directly and monitors GridTargetingState for tile changes. When both conditions are met (physics frame + new tile), calls PlacementSystem.try_build().\n\nArchitecture (v5.0.0): - One-way dependency: DragManager → PlacementSystem (calls try_build API) - PlacementSystem has NO knowledge of DragManager - Reads input directly via _input() to monitor confirm_build action state - Monitors GridTargetingState tile changes in _physics_process() - Physics-gated to prevent multiple builds per frame - Calls PlacementSystem.try_build() when conditions met\n\nUsage: - Add DragManager as a child of your World/Systems node in the scene - Call resolve_gb_dependencies(container) to inject dependencies - DragManager automatically handles input, drag lifecycle, and building
