问题
I have been trying to add the library named kivmob to display ads in my application. Kivmob loads the banner ad but does not load the interstitial ad. I am confused as to why the banner works but not the interstitial. I have also tried with test IDs. Here is my main.py.
from kivmob import KivMob
from kivy.uix.widget import Widget
from kivy.uix.screenmanager import ScreenManager, Screen, SlideTransition
from kivy.properties import NumericProperty, ReferenceListProperty, ObjectProperty
from kivy.vector import Vector
from kivy.clock import Clock
from kivy.core.window import Window
from kivy.utils import platform
from kivymd.uix.button import MDRectangleFlatButton
from kivymd.uix.dialog import MDDialog
from kivymd.app import MDApp
class PingPongPaddle(Widget):
score = NumericProperty(0)
def bounce_ball(self, ball):
if self.collide_widget(ball):
vx, vy = ball.velocity
offset = (ball.center_y - self.center_y) / (self.height / 2)
bounced = Vector(-1 * vx, vy)
vel = bounced * 1.05
ball.velocity = vel.x, vel.y + offset
class PingPongBall(Widget):
#Velocity on x and y axis
velocity_x = NumericProperty(0)
velocity_y = NumericProperty(0)
#So ball.velocity can be used
velocity = ReferenceListProperty(velocity_x, velocity_y)
#Moves the ball one step
def move(self):
self.pos = Vector(*self.velocity) + self.pos
class PingPongGame(Widget):
ball = ObjectProperty(None)
player1 = ObjectProperty(None)
player2 = ObjectProperty(None)
def play(self):
game = PingPongGame()
game.serve_ball()
#Runs every 60th of a second
Clock.schedule_interval(game.update, 1.0/60.0)
self.add_widget(game)
def serve_ball(self, vel=(7, 0)):
self.ball.center = self.center
self.ball.velocity = vel
def update(self, dt):
self.ball.move()
#Bounce off the paddles
self.player1.bounce_ball(self.ball)
self.player2.bounce_ball(self.ball)
#Bounce off top and bottom
if (self.ball.y < 0) or (self.ball.top > self.height):
self.ball.velocity_y *= -1
#Went off the side
if self.ball.x < self.x:
self.player2.score += 1
self.serve_ball(vel=(7, 0))
if self.ball.x > self.width:
self.player1.score += 1
self.serve_ball(vel=(-7, 0))
def on_touch_move(self, touch):
#To sense if screen is touched
if touch.x < self.width / 3:
self.player1.center_y = touch.y
if touch.x > self.width - self.width / 3:
self.player2.center_y = touch.y
class GameScreen(Screen):
def play(self):
game = PingPongGame()
game.serve_ball()
#Runs every 60th of a second
Clock.schedule_interval(game.update, 1.0/60.0)
self.add_widget(game)
ads.new_banner("ca-app-pub-xxxxxxxxxxxxxxxxxxxxxxxxx", top_pos=False)
ads.request_banner()
ads.show_banner()
class MainScreen(Screen):
def show_ad(self):
ads.new_interstitial("xxxxxxxxxxxxxxxxxxxxxxxxxxx")
ads.request_interstitial()
ads.is_interstitial_loaded()
ads.show_interstitial()
def on_resume(self):
self.ads.request_interstitial()
class PingPongApp(MDApp):
def __init__(self, **kwargs):
global ads
self.title = "Ping Pong"
if platform not in ("android", "ios"):
Window.size = (1000, 750)
ads = KivMob("ca-app-pub-xxxxxxxxxxxxxxxxxxxxxxxx")
super().__init__(**kwargs)
def build(self):
self.theme_cls.theme_style = "Dark"
screen_manager = ScreenManager(transition=SlideTransition())
screen_manager.add_widget(MainScreen(name="main"))
screen_manager.add_widget(GameScreen(name="game"))
return screen_manager
if __name__ == "__main__":
PingPongApp().run()
And here is my pingpong.kv.
#:kivy 1.11.1

GameScreen:
<MainScreen>:
FloatLayout:
MDRectangleFlatButton:

on_touch_down: root.manager.current = "game"

size_hint: None, None

<GameScreen>
on_enter: self.play()
<PingPongBall>:
size: 75, 75
canvas:

<PingPongPaddle>:
size: 50, 300
canvas:
Rectangle:

<PingPongGame>:
ball: PingPong_ball
player1: player_left
player2: player_right
canvas:
Rectangle:

size: 20, self.height
Label:

text: str(root.player1.score)
Label:
font_size: 140
center_x: root.width * 3 / 4
top: root.top - 50
text: str(root.player2.score)
Label:
font_size: 35
center_x: root.width * 6/7
top: root.top - 650
text: "by me"
PingPongBall:
id: PingPong_ball
center: self.parent.center
PingPongPaddle:
id: player_left
x: root.x
center_y: root.center_y
PingPongPaddle:
id: player_right
x: root.width - self.width
center_y: root.center_y
Thanks in advance!

Firstly you didn't call the show_ad() of Main screen.
You were thinking that the methods in the screen classes are invoked automatically on screen invoking,But thats not true.
You have to call the functions when entering the screen.
For doing so you need to change the following:
# This is your mainscreen class
class MainScreen(Screen):
def show_ad(self):
self.ads.new_interstitial("YOUR_ID_HERE")
self.ads.request_interstitial()
self.ads.is_interstitial_loaded()
self.ads.show_interstitial()
def on_resume(self):
self.ads.request_interstitial()
def on_pre_enter(self):
self.show_ad() #Functions called on screen
# invoked
