Features

A complete overview of what the Coding Passion Plugin Merger provides.

What this plugin is

The Coding Passion Plugin Merger is a reference add-on that shows how to combine the Wall Plugin (CodPassionWall) and the Dynamic Floor Plugin (DynamicFloorPlugin) into a single runtime building system.

It does not replace either plugin. It adds integration Blueprints and a playable demo map on top of them.

Runtime building features

Wall System

• Wall placement: select a wall item from the bottom bar and left-click to place
• Object placement: place objects (e.g. doors, windows) into walls
• Wall coloring: select a color → click “Wall Paint” → click two wall points to apply

Caution

TODO verify: Wall coloring — official source notes “Coming soon. Ask on Discord.” Verify whether this is fully shipped in v1.0.

Floor System

• Floor tile placement: select a floor texture → click PlaceFloor → left-click on the ground
• Room fill: hold Shift while placing floor tiles to automatically fill an entire room

---

Plugin switch UI

• Top buttons switch between Wall System and Floor System
• Switching is handled by BI_UiToMergerController (Blueprint Interface) → BP_PluginMergerController

---

Unified input routing

BP_PluginMergerController routes the following inputs to whichever plugin is currently active:

Input	Routed to
Left Mouse Button	Active plugin component
Right Mouse Button	Active plugin component
Left Shift	Active plugin component

Wall-Floor integration

BP_EditorWallWithFloorsBP connects walls to the Floor Plugin’s NodeSystem:

• Enables the Floor System to detect enclosed rooms formed by walls
• Registers wall event listeners on startup
• Updates the NodeSystem when walls are added or changed

→ See Wall-Floor Integration for a detailed explanation
