I have a problem with making ren'py analyze an user input

[enrap93]

hi, here I am again with another doubt, this time I'm not making a game, instad I'm maing a software to make the user learn some mathematic formulas... I decided to make it in ren'py because I have spent more time with this than others software-making programs...

so, wathever, i was making this program and i dont know what to do here (i simplified the formula by the way XD)...

Code: Select all

                
                    $ responce1 = renpy.input("how much is 2 + 2?")
                    if responce1 == "2 + 2": 
                        "Correct, the responce is [responce1]."
                    
                    else:
                        while responce1 != "2 + 2":
                            $ responce1 = ""
                            $ responce1 = renpy.input("incorrect, how much is 2 + 2?")
                    "Correct, the responce is [responce1]."

the problem when i do this is that the program keep saying that the respond is wrong, i keep typing 4, but the porgram keep saying is wrong...

so, yeah thats all, I have a week trying to correct this, but i can't do anything, so I really need your help...

"2 + 2" is a string, not an int or float value: Parse String to Float or Int

Just pointing out that "responce" should be "response"

You can try this snippet of code:

Code: Select all

    $ response1 = renpy.input("how much is 2 + 2?")                             
                                                                                
    while response1 != "4":                                                     
        $ response1 = renpy.input("incorrect, how much is 2 + 2?")              
                                                                                
    "Correct, the answer is [response1]."

Note that here the answer is not converted back to a number, but used as a string. So the same code should work with a question that requires a textual answer. For example:

Code: Select all

    $ response2 = renpy.input("Who is the superhero who fights the Joker?")     
                                                                                
    while response2 != "batman" and response2 != "Batman":                      
        $ response2 = renpy.input("Incorrect, who is the superhero who fights the Joker?")
                                                                                
    "Correct, the answer is [response2]."

When multiple right answers are possible, you have to account for them. Here we accept both a lowercase answer, and a capitailzed one.
(In this case, a better way would be to downcase the answer; but I wanted to show how to accept more than one answer, as it could be useful to you later on.)

thank you all very much for your responses!!!

"2 + 2" is a string, not an int or float value: Parse String to Float or Int

indeed, that was my problem, i have first to convert the words thatat the user have writed in a int or a float, now the program workds perfectly.

Just pointing out that "responce" should be "response"

yes, sorry XD I'm still having problems in writing english.


and thanks to "renpic" too, for your response.

now I can keep working in this program again. Thank you very much to you all again.
