Is there a way to test an object's "SemiTrans" value in an event? I thought that testing whether something was "invisible" would be the same as "Is SemiTrans("etc.")=128?," but apparently not. (I had my objects set to fade away and destroy themselves once invisible, but then one's death animation played a few seconds afterward, meaning it was still there after all...)

Well . . . try adding pick one to the event.
I've worked with this today and it works for me.
For some reason when you have multiple objects that are semi transparent and check to see if they are invisible, none of them get destroyed until ALL of them are invisible.
Adding pick one solves this problem.

Under Special -> Compare two general values.
SemiTrans( "Active" )
=
128
The "Compare two general values" doesn't work with multiples instances and groups though, so if this isn't for a unique object, it would be better to set one of the object's alterable values to it's SemiTransparency and then compare it to 128.

GamesterXIII: That's odd, cause these two objects go invisible at the exact same time. I shall keep that in mind anyway. 
Spitznagl: Thanks! Luckily, all of the objects I'm using the effect with never have multiple instances onscreen.

The death/destroyed animation plays when the object is destroyed via event. The object isn't destroyed until after the animation finishes. So, add the semitransparency to the destroy animation, and you can just destroy the object without any special conditions for transparency.

I see. I know you said there won't be multiple instances, but if one is at semi-transparency 127 and another gets created, when it hits 128 it will still exist until the next one hits 128, unless another is created again.

GamesterXIII: There aren't any objects being created, only two unique objects being destroyed: I'm working on an Arkanoid clone, and when the player finishes a level, I want the paddle and ball to fade away and terminate themselves (in case the paddle and ball might collide when invisible before the game jumps to the next frame, ruining the illusion. The ball could also fall out of the field and make the player lose a life inadvertently.)
Aphant: I'm actually using separate objects for death animations. Not necessarily the best way to do it, but using different sets of animations on the same object wouldn't save any coding, at least in this particular game. Plus I just got used to doing this when I used Game Maker.  The reason I knew the objects were still "alive" was that the invisible ball left the playing field and the player exploded.
