Effect: Execute stacks on failure
EffectNo. 9210
Synopsis
It works like Effect: Execute stacks, but only runs when the conditions in its own stack are not met. “On failure” refers to those conditions, not to a game error. Useful to show a warning or apply a consequence when someone does not meet a requirement.
Step by step
Call another stack when a condition fails
Boxes you need
- TriggerTrigger: Say something
- ConditionCondition: User on object
- EffectEffect: Execute stacks on failure
- EffectEffect: Show message
- Place a walkable object A. On a separate tile save “Show message” with “You need to step on A”, private to the triggering user.
- Build another stack with “Says something” (“test”), the “User on object” condition selecting A, and “Execute stacks if false”.
- In the effect select the message box on the first tile; use delay 0. Save everything.
- Say “test” off A; then step on A and say it again.
Result: Off A the warning appears. On A the condition passes, so the negative effect does not call the other stack.

Notes
- “If false” refers to the conditions in the stack containing this effect, not to a server failure.
