I just found out that making a rotating door with glass, that acts like a simple door with a "Use Only" flag, is harder than you think.
First problem occurs if you make the glass and the door two seperate func_doors entities with both having a "Use Only" flag. What happens is that when you press the use key in front of the door, you either trigger the glass, or the door frame, not both.
As an alternative you can but a trigger_multiple entity in front of the door, and make it trigger both the glass and the door frame. Only problem is that the doors opens even if you only pass by =|.
If there only was a way to trigger both the glass and the door frame at the same time by useing the use key.
A button could've done, but sadly u aint able to create pass-through button entities.
Anyone got an idea about how to solve this? thanks.
