I suppose you might as well try to pause the timer when it’s not being used. It might be still trying to scroll the text and that might be preventing you from calling “choicekfc”. Or not idk.
The other thing that comes to mind is whether you need to have the dialogue running to access the command? Though I doubt that would be the case.
edit: So I tried looking up some yarn examples. I don’t think it’s the timer. You’re right, it seems the timer is for the scrolling speed so, yeah. I’m still unsure if change scene can be done from the dialogue. Though you might want to try using a scene variable instead.
Like:
Declare a boolean scene variable, let’s say, “gotokfc” and set it to false.
Condition:
If command “choicekfc” is called
Trigger once
Action:
set “gotokfc” to true
And then create another event.
Condition:
If “gotokfc” is true
Trigger once
Action:
Change scene to “KFC”
Finally, you might need to have an end dialogue or something. This might help:
