Triggers - Chained "Value of Real Variable" events bug

Bug Report
1

Hello,

With much testing I discovered a bug with “Value of Real Variable” events in custom maps.

In short: the listener for “Value of Real Variable” events cannot be chained, because the 2nd listener will abort the first event, firing another event with a different real value instead.

To produce the bug you need the following triggers (in order):

  • A trigger1 that fires a sets the variable Real1 = 5.
  • A trigger2 that listens “Value of Real Variable” Real1 = 5, and then sets the variable Real2 = 10.
  • A trigger3 that listens “Value of Real Variable” Real1 = 5, and for example displays a log.
  • A trigger4 that listens “Value of Real Variable” Real2 = 10, and for example displays a log.
  • A trigger5 that listens an even THAT SHOULD NOT HAPPEN: “Value of Real Variable” Real1 = 10, and displays a log.

Then you will see the following behavior:

  • trigger1 fires the event “Real1 = 5”.
  • trigger2 detectes the event “Real1 = 5”, and fires an event “Real2 = 10”
  • trigger4 detects the event “Real2 = 10”.
  • trigger3 is never called: event “Real1 = 5” HAS BEEN ABORTED.
  • trigger5 is called: a NOT EXPECTED event “Real1 = 10” happens.

The issue disappears if there is no trigger4 . Probably because the listeners use a static reference ? Or if you add a “Wait 0.00s” before emitting the second event, so that it’s not chained but on 2 different frames.

Below is a copy of the necessary triggers:
