Always point upwards?

jackwilliamziegler

I need some help to get a 2d arrow shaped actor to always point up, no matter how the iPhone is oriented. Thanks

There may be a way to do this by using the accelerometer values, but I haven't tried it.

I played around with a right-facing arrow image and constrain attribute self.Rotation to game.Accelerometer.Y*(-90)+90 and it starts to approximate what you want if I hold the iPhone in landscape and then rotate it either way.

You might want to try the vector to angle function:
vectorToAngle(game.Accelerometer.X,game.Accelerometer.Y)

That should give you which way is "down". (Find "up" by adding 180.)
