Spline Based Blocking and Trigger Volume (SBBTV) is a versatile system designed to simplify the task of zoning out your scenes and levels. Unreal's standard blocking volumes are limited to trapezoidal meshes and the trigger system is similarly limited to capsules, spheres and boxes. With SBBTV you can build zones in any shape and size using the engines spline system. Not only can this save you time, but it is also significantly less tedious and finicky than the standard methods mentioned above. It also gives you more precise control over just where the player can and cannot go, and where they have to be to trigger events in your game. Additionally, using splines means that this is a non-destructive workflow that can easily be altered at any point in development!

Here's a brief performance demonstration video comparing the performance of Unreal Engine's blocking volumes with two implementations of SBBTV. Check the video description for a downloadable version of the demo to test it out yourself!

On release, SBBTV comes standard with the following features:

• A single drag and drop actor for each spline

• Passive and active blocking volumes - either simply stop your player/actors in their tracks, or give them a little nudge back towards the playable area

• Trigger volumes of any shape that can be defined by a spline

• One sided and two sided collision

• Procedural content support - just give the actor a list of spline points from your procedurally generated world and let SBBTV do the rest

• A versatile shader for building aesthetically pleasing borders (or set them to hidden and keep those walls invisible!)

• An extensive set of parameters to tweak and customise the system to your heart's content

• Clear, readable and well-documented blueprints to assist in extension, comprehension and learning

All blueprints are cleanly laid out, easy to read and well commented, and a detailed, publicly accessible documentation wiki ensures you will never be left confused. Discord support is also available and there's absolutely no need to leave a comment or review on the marketplace page to access either!
