hi Eric and thx for your help.
I tried but really, I don' get it "passes the printer method to the
*timeChange* arg." as my skills in maya programming are very limited. I
checked the
pymel.core.animation.keyframe class, found timeChange attribute....but
then.. I tried to query it expecting I could detect when currentTime
changes, but got no return value..
a = pm.keyframe(query = True, timeChange = True)
print a
In my case I am not sure that scriptJob is appropriate as it's mel and I
want to use python class object and avoid any kind of call like
"python(blabla...)"
My previous print time sample code is maybe confusing so I updated my code
trying to make it clearer. Basically I defined a CustomLocator object. Each
time a frame is played after pressing Start button a custom locator is
drawn. Right now the locator is drawn when pressing the start button. But
it's not drawn each time a frame is played or updated and I still can' t
figure how to do it...
class PlayBackDoSomething():
def __init__(self):
self.drawUI()
self.state = False
def drawUI(self):
if pm.window("UI_MainWindow", exists = True):
pm.deleteUI("UI_MainWindow")
pm.window("UI_MainWindow", title = "test playback...", w = 150, h =
150, mnb = False, mxb = False, sizeable = True)
pm.columnLayout("UI_MainLayout", w = 150, h =300)
pm.button("UI_pbStartButton", label = "Start", w = 150,
command=self.pbStart)
pm.button("UI_pbStopButton", label = "Stop", w = 150,
command=self.pbStop)
pm.showWindow("UI_MainWindow")
def pbStart(self,*args):
pm.play(state=True)
self.state = True
self.doTheJob()
def pbStop(self,*args):
pm.play(state=False)
self.state = False
self.stopTheJob()
def doTheJob(self):
#this is basically part of code that i want to execute each time a
frame is updated after pressing Play button
print ("start of job")
a = pm.keyframe(query = True, timeChange = True)
print a
t = pm.currentTime()
cl = CustomLocator(t, 0,0)
cl.draw()
def stopTheJob(self):
print ("end of job")
class CustomLocator():
def __init__(self, x, y, z):
self.x = x
self.y = y
self.z = z
def draw(self):
pm.spaceLocator( p=(self.x, self.y, self.z) )
pm.spaceLocator( p=(self.x, self.y, self.z-5) )
pm.spaceLocator( p=(self.x, self.y, self.z+5) )
def main():
pb = PlayBackDoSomething()
main()
Pseudo Code:
Press Start Button
>>Start Playback
>>>>While(currentTime changes):
DoTheJob()
Press Stop Button
>>Stop Playback
