Play a sound after a specific sound in a different event played

I want to be able to play a second follow-up sound from one event after a specific sound from a different event already played.

I tried Adding a Condition, but the event wasn’t listed in the parameters.

It is possible. Do you want to trigger a new event instance that plays the new sound, or to alter the behaviour of an existing event instance to make it play the sound?

If you want to trigger another event instance, an event instrument or “start event” command instrument would do what you want.

If you want to control the behaviour of another event, the tool for that is parameters. Parameters can be set from your game’s code, or by “set parameter” and “incremenet parameter” command instruments. If you want to set a parameter from one event instance and have it affect another event instance, it will need to be a global parameter.
