Variable <unknown_object> ->Also, what does this mean?

 

[seojaeoh]

Is there a difference between an editor and an annotation?

The error message is referring to your destroy event's second line which apparently is trying to reference an instance that does not exist.

Variable <unknown_object>.spaceup (Does this mean I don't know the spaceup that I made?)

you are trying to read the value of the "spaceup" variable of an undefined object. for this gm returns you error. Check the name of the object from which to read the value of the variable you indicated.

What does "spaceup" variable mean for an undefined object? I wrote down the room_start event in object34.

 

[Vallo92]

In your code you created a variable called "spaceup" and you are checking it during the destroy event.
Did you write the code or did a copy / paste without reading it?

What does "spaceup" variable mean for an undefined object? I wrote down the room_start event in object34.

You're starting to sound like a broken record here. Post all the code in object34 and clearly state which event each comes from, the line in the error message isn't the only one that's wrong.

Also, declaring instances variables in the Room Start event is a dumb rookie habit. If you create instances of that object while a room is already running, those instances won't run their Room Start event and they'll be left without those variables. Sensible GM users declare instance variables in the Create event.
