Keypad Door Puzzle System – Unreal Engine
Keypad Door Puzzle System – Unreal Engine
Keypad Door Puzzle System is a lightweight, plug-and-play Blueprint system for Unreal Engine that lets players unlock doors by entering a code on an interactable keypad/terminal.
Key Features:
Per-Door Code Storage: each Door stores its own combination (e.g. Combo).
Simple Linking: each BP_Keypad links to the correct Door (e.g. TargetDoor reference).
Fast Setup: set the Door code, assign the Door reference in the Keypad, and you’re ready.
Reusable & Modular: place unlimited door/keypad pairs across your levels.
Demo Ready: easy to showcase and integrate into puzzle/escape/adventure gameplay.
How To Use (Quick Setup)
Place the Door Blueprint in the level and set its Combo value.
Place BP_Keypad near the door.
In BP_Keypad, assign TargetDoor to the Door instance you want to unlock.
Play → interact with the keypad → enter the correct code → door opens.
