DelayInterpreter.DelayInterpreter Class Reference
Detailed Description
Delay commands: AT_TIME takes the specified time and AT_DELAY specifies the delay before the message is to be executed.
Because the resolution is frame rate, the only thing we can guarantee is that the message won't be issue before its scheduled time.
For example:
self.sendMessage("AT_DELAY",(1.0,'HEADS_UP_DISPLAY_SET_MODE',(False,))) self.sendMessage("AT_DELAY",(4.0,'HEADS_UP_DISPLAY_SET_MODE',(True,)))
will turn off the heads up display in 1s, then back on 3s after that.
Some implementation notes:
We don't have the "at wall clock time"; may come in handy for some applications and it wouldn't be difficult to add.

| DelayInterpreter.DelayInterpreter.tick | ( | ) |
Remember that since this method is invoked by a timer it is called from a different thread.
This means in general that this method must be thread safe. Typically it will just trigger a redraw or queue a message.
