Hello, I have and idea on a hostage map that I had not seen done before. I had an idea about making the hostage rescue have a timer where the CTs would have to stay in the rescue zone for matter of a few seconds to rescue the hostage. Thematically this would be waiting for an elevator, blastdoor, helicopter pick up, etc. I wanted to experiment with how this might effect the asymmetric nature of hostage rescue. The mechanical way to execute this, I believe, is to make a trigger that will only work if a CTs enters and it with a hostage. The test I am trying is a door that opens to the rescue zone. My issue is that I haven't really mapped since the late 2000s and I am running to the limit of my knowledge on how to do this. I have looked at all kinds of resources and I cant find a way to filter for CT carrying the hostage. Any help is much appreciated.
Some details on the maps theme and layout: Granite quarry of sorts. Hostage A is in or on the roof of a small building. Hostage B is in bottom of a dilapidated warehouse. CT spawns entrance of the quarry. T spawns at the back of the quarry. Rescue zone in the middle, but I would like to experiment with a second rescue in the terrorist spawn. But that might be too chaotic.
