Full 360 Accelerometer Rotation Question

BlackbirdStudios

Hey guys,

So I am working on a game and I want the actor to be able to turn all 360 degrees based on the accelerometer position. (meaning its rotation can be anywhere from 0-360 degrees) Can I do this with one simple equation or will I have to configure individual equations based on different accelerometer positions?

Any help appreciated

Thanks,

BUMP, anyone help?

Are you looking 'one simple equation' to get the accelerometer data?

make a game level attribute: accelAngle (real)

In a timer:
Change Attribute: accelAngle To:(vectorToAngle(game.Accelerometer.X,game.Accelerometer.Y)+90)%360

The "+90" is for landscape mode ( change as necessary)
The %360 is to make sure accelAngle does not end up higher than 360 (especially if 90 degrees gets added to it.)

And where should this be inserted in the game? As the rotation for the actor?

Oh -- I see what you are asking now. (I was answering a slightly different question.)

Yes -- sort of. In an actor put the following constrain behavior:

Constrain attribute: (self.Rotation) To: (vectorToAngle(game.Accelerometer.X,game.Accelerometer.Y)-90)%360)

Its a little jerky doing it that way but it might do.
