waitInterval ignores state?

[Nox_firegalaxy]

Hi,

currently Im looking for a way to wait for a specific event in a sequence:
codepad.org/1GeLwpvP

If I made no misstake CWaitInterval seems to ignore to state completely. Pausing and then resuming a 0.1 WaitInterval does not work either. Did I miss something? Is there a other way to finsih a Wait prematurely? Is it possible to change the duration?

You are trying to use an interval for a purpose beyond its intended design. Intervals aren’t meant to be dynamic in duration like this; and although you can extend an Interval’s behavior through subclassing, it would be a bit more complex than what you are doing here.

Instead, consider using a task for this purpose.

Well anyway according to panda3d.org/manual/index.php/Intervals

Normally, an Interval will play to the end and stop by itself, but you can stop a playing Interval prematurely:

interval.finish()
This will stop the interval and move its state to its final state, as if it had played to the end. This is a very important point, and it allows you to define critical cleanup actions within the interval itself, which are guaranteed to have been performed by the time the interval is finished.

You can also temporarily pause and resume an interval:

interval.pause()
interval.resume()
If you pause an interval and never resume or finish it, the remaining actions in the interval will not be performed.

And you can jump around in time within an interval:

interval.setT(time)

Does not this apply to WaitInterval as well? Of course I can use a task but this way I cant use Sequences and have to handle it by my own

That is the interface for controlling a playing interval from outside. It doesn’t work that way from within the interval itself.

When you embed an interval within a Sequence, it doesn’t really play the interval directly. Instead, only the outermost Sequence is “playing”; and all of the intervals nested within it are invoked (but not “played”) in the appropriate order. This is all a very sophisticated system designed to optimize the playback of complex intervals. You can’t call finish() on a deeply nested interval, because nested intervals aren’t in a playing state.

What you’re trying to do can very naturally be expressed in two functions, without even using the task system:

def func1(self):
    self.video.play()
    self.sound.play()
    self.accept("mouse1", self.continue)
    self.accept(self.video.getFinishedEvent(), self.continue)

def func2(self):
    self.ignoreAll()
    self.openAP()

self.func1()
