Counters are a type of wall mechanic, this means they must be place on a wall tile. A counter is used when more than one action is required for a dungeon mechanism.
There are 6 actions available to a counter: None, Activate, Deactivate, Toggle, Release, or Destroy.
Up to 8 targets can be selected by a single counter, eg up to eight doors can be opened.
Defines the chance the action will take place. 100% means it always will.
Defines the time in 1/6s of a second for the action to take place when the count is meet.
The most important part of the counter. To perform the action the count must reach 0, eg setting this to 2 will mean it will require 2 activations by a trigger before it will take place.
Activating a counter will decrease its count by one.
