Here is a Number Guessing Game I copied from a Youtube video especially made for Anvil. I made it as a tutorial and to add on if you would like. Credit goes to the video.
Two issues I have is:
ValueError: invalid literal for int() with base 10: ‘’ when no number is typed.
And I do not know how to restart the game when it’s done.
This function should restart any Anvil app:
from anvil.js import window
def reload_current_tab():
window.location.reload()
Hi @rcrodney34,
For your ValueError just make sure you test the input of the user before trying to do anything with it.
if guess == "":
Notification("You forgot to fill in a number. Try again.", "Error", style="danger").show()
else:
try:
guess = int(guess)
self.counter += 1
self.label_4.text = f"You guessed {self.counter} time(s)."
if guess == self.number:
self.label_1.text = f"{guess} is the correct number!"
elif guess < self.number:
self.label_1.text = f"{guess} is lower than the correct number."
else:
self.label_1.text = f"{guess} is higher than the correct number."
except ValueError:
Notification(f"{guess} is not a valid number. Try again.", "Error", style="danger").show()
Then for restarting the game. That’s a matter of changing your App’s structure and creating a function start_game
You should choose Standard Page just for one of your Forms. Then any other subsequent Form should be Blank Panel. This allows you to change the content_panel of your Standard Page Form to load other forms.
See more info here:
The start_game function can be called from within the Game Form. We are calling this each time the form is loaded as well.
def start_game (self):
self.lower_treshold = 1
self.higher_treshold = 10
self.number = random.randint(self.lower_treshold, self.higher_treshold)
#displays answer in code
print(self.number)
#creates a counter
self.counter = 0
self.label_1.text = ""
self.label_4.text = ""
Notification("A new random number has been generated.", "Welcome", style="success").show()
You can find all the code here:
Bonus
If your form has variables defined as for example self.lower_treshold, then you can use them in your components as well. Just make sure you have assigned those variables before you try to self.init_components(**properties)
