I'd just check if they have the achievement (i.e. if platinum_achievement.has()) as a condition like you would use anywhere else - you can use it to wrap screen language too to show a button only if the player has the platinum achievement, for example.
Ah, I'm kind of new at coding especially within Python. I attempted to type "if platinum_achievement.has()" and it ended up just showing an error.
Code itself :
"
if platinum_achievement.has()
e "This is a Test"
"
Then the error code
```
I'm sorry, but errors were detected in your script. Please correct the
errors listed below, and try again.
File "game/script.rpy", line 74: reached end of line when expecting ':'.
if platinum_achievement.has()

I apologize if this might be a stupid question
