Fab Marketplace: Puzzle Logic System

​

This is an Unreal Engine asset I made for the Fab Marketplace. It contains a large set of game ready objects such as doors, levers, teleporters and many more. The goal is to provide a set of easy to use tools to allow developers with limited blueprint experience to start building gameplay immediately. It is currently rated 5/5 on the Fab Marketplace.

​

  • 17 ready to use objects such as doors, levers, triggers and logic components such as counters and timers.

  • Blueprint interface and a linking system facilitates communication between puzzle objects.

  • Allows users to create custom puzzle logic objects or extend functionality of included assets. ​

  • Made entirely in blueprints.

  • Easily integrate-able into existing projects.

I made a fairly extensive puzzle game to demonstrate the included objects. Setting up all the logic was a great way for me to test the system and find bugs and usability issues. I used an existing tile-set I previously made to build the  level geometry.

This 3rd person demo in a mechanics level provides a more direct demonstration of all the features. As shown, the system can work with any character pawn. It has no dependencies and can be dropped into any project and should work right away without needing to configure anything.
