That's right, not just for sim crossings anymore! Ever wanted an easy unidirectional door, a false floor, a ceiling you can fly in to but not out of, some fancy technology for your maze, or the pure fun and joy of your own one-way prim? Well the technology has arrived!
The 1-way prim can be modified to any size and textured to your heart's content. Buy the builder's pack and get a copiable 1way wall for all your creative projects. Surround your parcel to let people in, but not out - or out but not in. It's up to you!
This miracle of technology works in any orientation and the full range of shapes and sizes. The magic is handled by a lagless script that turns a plain old prim into a unique and wonderful tool.
