What @jack meant move the create action up the in the event it was in, not move it up into another event.
What you were doing was changing the animation of the object and tweening it’s opacity before it was created.
You create frontEnemy at 1618 on the x axis. Is that where the camera is? Does the word “Success” appear in NewObject8?
I suggest you do a little debugging for yourself. In the second event, take out both conditions. Does the sprite appear? If so, add the conditions, one at a time and preview again, until it fails.Tthe last condition you added will the bug.
Also, you are still referencing frontEnemy in the first event. Unless you have one already in the scene, it’s accessing something that doesn’t yet exist.
[edit]
I see this isn’t your scene script, so I assume it’s an External Event. Is it linked to in the scene events?
