For that matter, how would one use the *input_text command for a riddle or question? (Much like in Unnatural’s test).
I can’t help you with changing the appearance of the box, but using *input_text for an answer to a riddle/question is quite easy.
Create a string variable that will hold the player’s answer (let’s call it player_answer). When you ask your question, use *input_text player_answer to show the box. After the player answers, use an *if command to check whether the answer is correct or not by comparing it to a string you want the answer to the current question to be.
In case I explained this badly, here is an example.
*create player_answer "" *label question1 What mythological creature has the body of a human and the head of a bull? *input_text player_answer *if (player_answer = "minotaur") That is correct! *page_break *goto question2 *else Unfortunately, your answer is incorrect. Try again. *page_break *goto question1 *label question2 blah blah blah
