Hi - I'm trying to find a way to allow the rezzing of a gate, on the other side of our sim, when raiders cross a certain point. I'm struggling somewhat with the 10m issue. I've tried a few options, including Innula's tutorial - and also Erwin's trigger script for Casper's Rez2 script. Neither seem to work exactly as I need. In essence, it's simply to drop a prim gate in place 70m or so from the arrival raid point, as raiders tread on the collision mat. The gate to have an adjustable timer to vanish too. The closest I have - is the SimKing TR - works ideally - but isn't on collision, and is non mod. I'm sure I'm missing something obvious - any suggestions welcomed!
