Why are my Door Open Stay's closing?!

[Jenuall]

Hi there,

 

I've just started getting back into messing around with Doom mapping for the first time since dabbling in it during the mid-90s so I'm still getting my head around how the tools work these days. I've been watching tutorials on UDM and have been slowly getting to grips with things but have hit a bit of a snag when trying to create some monster closet style traps.

 

I've created some sectors to act as my closet doors, tagged them and linked them to a linedef using the "W1 Door Open Stay (fast)" action, all of which seems to work fine: I can walk over the linedef to trigger the doors opening perfectly fine... except then the doors seem to keep trying to close instead of staying open!

 

Here's what my setup looks like in the editor:

 

 

And this is my settings for the triggering linedef:

 

 

And finally an example of one of the door sectors:

 

 

I've tried fiddling with the settings on the door sectors and linedef, as well as looking at things like the height of adjacent sectors etc. but nothing seems to be bringing me much joy - the doors seem to keep wanting to close after a few seconds! 

 

Any advice would be appreciated!

Are there D1/DR actions on the lines of the door? If so, the monsters may be activating them as they pass through the doors, and that would make the doors close after a few seconds.

 

Another issue which may trip you up: You aren't quite doing the doors properly. There are small sectors to the sides of the doors. Those should not exist. That should be void space. Doors open to 4 below the lowest ceiling, so if there are sectors beside the door, those will also be taken into account. If the sector is a 0-height sector set to the same height as the floor, then a door won't work.

That was it - I'd somehow put DR actions on the door lines!

 

Thanks for the tip on the sectors alongside the doors as well - I hadn't noticed that those had been filled in when I drew out the geometry
