@deprecated Use [ScenePlacementEntry] instead. Placeable is kept as a backward-compatible alias through the 6.0 deprecation window. It extends [ScenePlacementEntry] so existing [code].tres[/code] files referencing [code]placeable.gd[/code] by script path continue to load normally. This alias is scheduled for removal in a future release. Migrate to [ScenePlacementEntry] by replacing [code]Placeable[/code] references in code and updating [code].tres[/code] [code]script_class[/code] lines before upgrading.
