PlaceableSequence | Grid Placement Docs

Draft — Unreleased:This page is in active development. APIs, class names, and behavior may change before the release is finalized. Use it as a preview of what's coming — not as a stable integration target.

Groups multiple placeable variants under a single selectable slot for UI selection. PlaceableSequence allows players to cycle through related building variants (e.g., Basic Tower → Heavy Tower → Rapid Tower) before placing on the grid. Each sequence contains an ordered array of ScenePlacementEntry resources that share a common purpose but have different properties, visuals, or functionality. Key Features:

Ordered variant collection with left/right cycling in UI
Automatic arrow button display when 2+ variants exist
Compatible with PlaceableList and PlaceableSequenceSelectionUI
Validation delegation to individual ScenePlacementEntry objects Usage Example: [codeblock] var tower_sequence := PlaceableSequence.new() tower_sequence.display_name = "Defense Towers" tower_sequence.placeables = [basic_tower, heavy_tower, rapid_tower] [/codeblock] Integration:
Use with PlaceableSequenceSelectionUI for tabbed variant selection
Compatible with existing PlacementSystem placement workflow
Each variant maintains its own placement rules and validation
