Need help with 3 stage construction

(Bluebomber) #1

Alright, im a mapping noob and need some help with a few things.

  1. I have this 3 stage construction on my map and i cant get each stage to be destroyed one at a time. so can anyone tell me how to get it to go back to the previous stage?
    never mind, i figured out what i did wrong with my construction, but i still need help with the other 2 problems.

  2. how do i make a door open if its part of a construction?

  3. how can i make a door open if someone steps into a trigger?

Thanks in advance for all the help
