I am trying to create a splash screen type Scene. In theory there
should be two labels that, from the bottom, rise up, then fall back
down, one after the other. I have tired to use the actions in a way I
think would be good for doing complex sequences in order but nothing
happens. Its hard to explain what's going on here, but the code should
be easy enough to understand. Why do I get a blank screen?
import cocos
from cocos.director import director
from cocos.actions import *
class ByLineLayer(cocos.layer.Layer):
def __init__(self):
super(ByLineLayer, self).__init__()
writtenby = self.writtenby_label()
ldlework = self.ldlework_label()
self.action = writtenby.action + ldlework.action
self.add(writtenby)
self.add(ldlework)
def writtenby_label(self):
label = cocos.text.Label('Written By',
font_name = 'Times New Roman',
font_size = 30,
anchor_x = 'center', anchor_y =
'center')
label.position = 320, -50
# Action Behavior
moveup = AccelDeccel(MoveTo((320, 300), 2))
movedown = Accelerate(MoveTo((320, -50), 1.5))
label.action = Delay(0.1) + CallFunc(label.do, moveup +
movedown)
return label
def ldlework_label(self):
label = cocos.text.Label('ldlework',
font_name = 'Times New Roman',
font_size = 32,
anchor_x = 'center', anchor_y =
'center')
label.position = 320, -50
# Action Behavior
moveup = AccelDeccel(MoveTo((320, 300), 2))
movedown = Accelerate(MoveTo((320, -50), 1.5))
label.action = Delay(0.1) + CallFunc(label.do, Delay(3) +
moveup + movedown)
return label
class SplashScene(cocos.scene.Scene):
def __init__(self, nextsceneclass, *args, **kwargs):
self.next_scene_class = nextsceneclass
self.layers = [ByLineLayer()]
self.action = Delay(0.10)
for l in self.layers:
self.action += l.action
self.action += CallFunc(self.next_scene)
super(SplashScene, self).__init__(*self.layers)
self.do(self.action)
print self.action
def next_scene(self):
director.replace(self.next_scene_class())
if "__main__" == __name__:
director.init(width=640, height=480)
director.run(SplashScene(cocos.scene.Scene))
