Signal
The signal attribute is used to check whether a signal string matches the one sent by a signal mechanic.
You can see the official MythicMobs documentation for the signal mechanic here.
When the player receives a signal (via MythicMobs mechanic), the ability with matching activator: SIGNAL and signal: <value> will be executed.
Example¶
If you trigger this mechanic:
It will activate any ability on the player's item that matches activator: SIGNAL and has signal: example_signal.
MythicMobs/items/example_item.yml
Example:
  Id: STICK
  Abilities:
  - skill: SummonSkeleton
    activator: SIGNAL
    signal: example_signal
Note
If the activator is SIGNAL but the signal attribute is not set, the ability will be triggered by any signal applied to the player.
