> -- "steering" effects for driving simulators and games To get the steering effect you will probably want to set up your sensor listener to listen for SENSOR_ORIENTATION rather than SENSOR_ACCELEROMETER because the ORIENTATION sensor will let you know the angle that the various axis of the phone are angled at. Well anyways here is a cut down code snip from my PingPong and BreakTheBlocks games. Basically I detect how much of an angle the phone is on and set the position of the bottom paddle according to that. it might be a little confusing please let me know if you have more questions about this code snippet. I think I am planning on writing all of this up[ in a blog post for my own reference in the future, will post back in this thread if that ever happens.
And the bets tool that is available for trying to understand the raw data that you can receive from the android SensorListener can be gathered by playign with the OpenIntents Sensor Simulator http://www.openintents.org/en/node/6 public void doSensorChanged(int sensor, float[] values) { if((sensor == SensorManager.SENSOR_ORIENTATION)) { float max_angle = 25.0f; float adjustedRollValue = values[2] + 90.0f; float percentileValue = 0.0f; if(adjustedRollValue < (90.0f - max_angle)) { percentileValue = 0.0f; } else if(adjustedRollValue > (90.0f + max_angle)) { percentileValue = 100.0f; } else { percentileValue = ((adjustedRollValue-(90.0f - max_angle)) / (max_angle * 2.0f)); } float xPos = m_canvasRect.width() * percentileValue; m_paddleCenterX = Math.round(xPos); } } Good luck ---snctln www.snctln.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
