This code displays the image assassin1.png on a black background. As soon as I press the key the image moves to the right and stops moving as soon as I release the key.
As soon as I press the key it should also change to the image assassin2.png and when I release the key it should change back to assassin1.png.
This code however never displays the assassin2.png image while moving. Why is this so and how can I fix this?
import pyglet
class Assassin(pyglet.sprite.Sprite):
def __init__(self, batch, img):
pyglet.sprite.Sprite.__init__(self, img, x = 50, y = 30)
def stand(self):
self.img = pyglet.image.load("assassin1.png")
return self
def move(self):
self.img = pyglet.image.load('assassin2.png')
return self
class Game(pyglet.window.Window):
def __init__(self):
pyglet.window.Window.__init__(self, width = 315, height = 220)
self.batch_draw = pyglet.graphics.Batch()
self.player = Assassin(batch = self.batch_draw, img = pyglet.image.load("assassin1.png"))
self.keys_held = []
self.schedule = pyglet.clock.schedule_interval(func = self.update, interval = 1/60.)
def on_draw(self):
self.clear()
self.batch_draw.draw()
self.player.draw()
def on_key_press(self, symbol, modifiers):
self.keys_held.append(symbol)
if symbol == pyglet.window.key.RIGHT:
self.player = self.player.move()
print "The 'RIGHT' key was pressed"
def on_key_release(self, symbol, modifiers):
self.keys_held.pop(self.keys_held.index(symbol))
self.player = self.player.stand()
print "The 'RIGHT' key was released"
def update(self, interval):
if pyglet.window.key.RIGHT in self.keys_held:
self.player.x += 50 * interval
if __name__ == "__main__":
window = Game()
pyglet.app.run()
I looked at the pyglet's source code and i think the problem is here:
self.img = pyglet.image.load(...
The image is stored in self.image variable, not self.img. So changing to:
self.image = pyglet.image.load(...
should update the image that the sprite is using.
