! Coding help I keep getting warnings!

I keep getting the “WARNINGS use @character enters from X to screen Y”

Wtf does this mean? I’ve tried…
@nova enters from right to screen right
@nova enters FROM right to screen right
@nova enters from X to screen Y

And I still get the same warning. What am I doing wrong?
Is there a cheat sheet of codes are their meaning or action I could use?

Everything I attempt to do gets a warning.

You need to write you characters name in capital letters.
@NOVA enters from right to screen right

Thanks! Do you know if there’s a cheat sheet of codes or something that shows which codes to use to get certain actions or behaviors?

I don’t sorry but if you want a character to enter the stage while doing a particular animation you can use either of these. Lets say your character is named BOB

@BOB enters from left/right to screen (Insert where you want your character to go) and BOB is (Insert animation)

Or

@BOB enters from left/right to screen (Insert where you want your character to go) and BOB does it while (Insert animation)

Hope that made sense

Also is you want a character to do something while they are already on stage its

@BOB is (insert animation)
This code is used when the character is already on stage.

You can also use a starting position (character is already on screen without needing to enter)

@BOB stands screen (wherever you want them to stand) and BOB is (insert animation)
