In this video we’ll start to build out a Tic Tac Toe game with Kivy and Python!

Tic Tac Toe is a simple game, but it’ll allow us to learn how to use basic logic with Kivy.

In this video we’ll build out the GUI for our game, as well as the restart button functionality.

#kivy #codemy

Python Code:
GitHub Code:

from kivy.lang import Builder
from import MDApp

class MainApp(MDApp):
	def build(self):
		self.theme_cls.theme_style = "Dark"
		self.theme_cls.primary_palette = "BlueGray"
		return Builder.load_file('toe.kv')
	# Define Who's turn it is
	turn = "X"


	def presser(self, btn):
		if self.turn == 'X':
			btn.text = "X"
			btn.disabled = True
			self.root.ids.score.text = "O's Turn!"
			self.turn = "O"
			btn.text = "O"
			btn.disabled = True
			self.root.ids.score.text = "X's Turn!"
			self.turn = "X"

		# Check To See if won

	def restart(self):
		# Reset Who's Turn It Is
		self.turn = "X"

		# Enable The Buttons
		self.root.ids.btn1.disabled = False
		self.root.ids.btn2.disabled = False
		self.root.ids.btn3.disabled = False
		self.root.ids.btn4.disabled = False
		self.root.ids.btn5.disabled = False
		self.root.ids.btn6.disabled = False
		self.root.ids.btn7.disabled = False
		self.root.ids.btn8.disabled = False
		self.root.ids.btn9.disabled = False

		# Clear The Buttons
		self.root.ids.btn1.text = ""
		self.root.ids.btn2.text = ""
		self.root.ids.btn3.text = ""
		self.root.ids.btn4.text = ""
		self.root.ids.btn5.text = ""
		self.root.ids.btn6.text = ""
		self.root.ids.btn7.text = ""
		self.root.ids.btn8.text = ""
		self.root.ids.btn9.text = ""

		# Reset The Score Label
		self.root.ids.score.text = "X GOES FIRST!"
