Question by rd42 · Apr 28, 2010 at 08:02 PM · iphoneaccelerometer

Bag Toss Unity Accelerometer

I want to gather the accelerometer data from a toss motion on the iPhone in Unity and compute velocity so I can then animate a bag toss. I've completed a tutorial where I used a change in the accelerometer to make a ball roll, but I can't figure out how to translate that knowledge into tossing a bag or a ball. Any links, suggestions tutorials would be appreciated. Thanks!

I haven't tried but you can add the accelerometer input to a total so long as it keeps moving in one direction, when the movement stops you will have a value for total power (power = force x distance / time) Then you can tweak it on an actual phone or let the player calibrate the effect themselves.

somet$$anonymous$$ng like:

if(iPhoneInput.acceleration.y>0){
   time += Time.deltaTime;
   total += iPhoneInput.acceleration.y;
} else {
  // object is thrown, calculate power
}

That sounds perfect, I just need to figure out how to add it up to a total.

is it not a simple case of total += accelerometer input?

Thanks spinaljack, I'll try it out.

The conditional works, but I'm not sure if the totaling works. I tried adding print(total); but nothing shows up in the console. I guess the other question will be is how to break out of the function once the ball is thrown so it doesn't keep resetting. Thanks again for helping me... get the ball rolling.

you'd need another boolean like CanThrow in the statement and set it to false after throwing and then true at the start of the next round. Also make sure you initialise total with var total = 0.0 If that doesn't work... ask again I guess :)
