Triggering Effects with Events
Some effects, like the Explosion, need to be triggered by an event.
For example, to have an explosion occur when clicking on a button, use the following event and scene set up. You can even open this experience on the games workspace: Triggering Effects with Events
On: Interaction Start
Then: Other Object (and then click on the Explosion object in the scene)
Trigger Effect
That set up activate the explosion effect each time the "button" is clicked. Use that same approach to trigger any effect that has a "Play Effect" button in its Object tab:
Pro Tip: Use the "Deactivate" event action on objects around the explosion to simulate them getting destroyed!
