You can use any type of door with this effect. The Touchplate Door opens when you step on a certain sector designated as a "Touchplate".
Touchplate Door with Activator
This type of door has its own special properties: (a) The door cannot be opened manually. (b) You can control the amount of times it will work.
Construct any type of door so it functions in the game. Now place an A[Mode,Channel] in your door sector. Valid values for Mode are: [0] = default, [1] = open door only*, [2] = close door only*. Place a T[NumberOfActivations,Channel] in your Touchplate sector. NumberOfActivations is the number of times the Touchplate will activate the door (0 being infinite). If you choose to use NumberOfActivations, make sure the last activation won't leave the door closed, or the player will be trapped!
* These modes are only intended to work with vertical doors.
Touchplate Door with MasterSwitch
This type of door has its own special properties: (a) It will only activate once, then you must open it manually. (b) It has a time-delay ability.
Construct any type of door so it functions in the game. Now place a D[Delay,Channel] in your door sector. The Delay value is the amount of time before the door activates. A Delay value of 30 = 1 second. Place a T[0,Channel] in your Touchplate sector.
