using i900 joystick in a taskFunction
Hi,
What I'm trying to do is, using the buttons on the joystick to scale my virtual world. I'm using a task know, but it seems that the event doesn't get triggered when using "viz.SENSOR_UP_EVENT". If I use "viztask.waitSensorDown" then I don't know what to put in it as a button. I've tried the state things from the manual "joystickSensor.get()[7]" but it doesn't give me the actual pressed button wich I have to put in, right? Code:
def scaleOnSensorEvent() : dataObject = viz.Data sensorData = joystickSensor.get() while True : yield viztask.waitEvent(viz.SENSOR_UP_EVENT, dataObject) # yield viztask.waitSensorDown(joystickSensor, button??, dataObject) print "something" if viz.get(viz.TRACKER): headSensor = viz.add('intersense.dls') viz.tracker() headSensor.reset() joystickSensor = viz.add('intersense.dls') viz.tracker() joystickSensor.reset() viztask.schedule(scaleOnSensorEvent) Last edited by krimble; 06-04-2008 at 05:15 AM. |

The intersense.dls plugin does not generate sensor up/down events. You need to manually check the button state by examining the value at index 7 of the data array. The documentation for the intersense plugin has sample code showing how to check for the button state of the joystick.

Thank you,
I've used a timer now, and it works. It would be handy though to be able to use a task with the IS-900 joystick (wand). The use of tasks makes it a whole lot easier, great concept! |

You can create your own custom task conditions. For example, here are two conditions that wait for an IS900 button to be pressed or released:
Code:
class waitIS900Down( viztask.Condition ): def __init__( self, sensor, button ): self._sensor = sensor self._button = button def update( self ): return int(self._sensor.getData()[7]) & self._button class waitIS900Up( viztask.Condition ): def __init__( self, sensor, button ): self._sensor = sensor self._button = button def update( self ): return (int(self._sensor.getData()[7]) & self._button) == 0 Code:
. . . yield waitIS900Down(isense,1) print 'Button 1 pressed' yield waitIS900Up(isense,1) print 'Button 1 released' . . . |
