Advanced Accelerometer Help

AppFueled

I followed T Shirt Booth's accelerometer tutorial. The game works great if you want to hold the iphone completely flat. But I would like to change the configuration so people who are sitting and holding the iphone at an angle (maybe 30 degrees) can also play the game.

Does anyone know what I need to change the numbers to?

For example, right now, each direction is: if the game.accelerometer is < (or >) -0.1 (or 0.1), So, what would I need the numbers to be?

THANKS!

Here's what I do. Create a calibrate button or just use your start button on your main menu. Add the following code for a landscape game:

change attribute game.Calibrate (real) to abs(game.accelerometer.X)

Then in the tilt controlled actors do this:

Any where that you have used game.accelerometer.X change it to this:

(game.accelerometer.X+game.Calibrate)

Thanks, I will try it.

I tried what you said but I feel I may be doing something wrong. Where I have game.accelerometer.x > .1, I replaced .1 with (game.accelerometer.x+game.calibrate) but it didn't work. Does it look like I did something wrong?

no dont replace the .1, replace the accelerometer.

So when (game.acelerometer.X+game.calibrate) > 0.1

Thanks for the reply Jon.

The problem I am having is that I can't get (game.acelerometer.X+game.calibrate) inside the field. It only allows me to select one attribute. When I try to add both, it just overwrites the other. If I try and write it in the field, it doesn't work. ???

make another attribute, constrain it to (game.accelerometer.X+game.calibrate) and use that attribute

AppFueled

Thanks again for your help John. I tried what you wrote and it worked.

Is there any way to make the actor move when I slightly tilt the device. It seems that I need to tilt the device quite a bit for it to move forward or backward. ??? Thanks!

make another attribute, constrain it to (game.accelerometer.X+game.calibrate) and use that attribute

AppFueled

never mind. I think I got it. Thanks again.

Change 0.1 to 0.01 or until it suits your needs.

I got it working but it doesn't matter if I choose .01 or .0001 for the accelerometer, I basically need to tilt it about the same to get it moving. Do you have any ideas?

make another attribute, constrain it to (game.accelerometer.X+game.calibrate) and use that attribute

AppFueled

Still not working. I tried .1 and even .0001 and I still need to tilt it about the same to - either way - to get it moving...

Change 0.1 to 0.01 or until it suits your needs.

When I calibrate the accelerometer, it doesn't matter what number I use ie., .1 or .00001, the sensitivity doesn't change. The calibration works great, I just can't make the accelerometer more sensitive. In fact, in order to move forward or backward, I have to tilt at least 30 degrees.

I also tried without the calibration, and the sensitivity works just fine.

Anyone have any ideas?

I didnt really look threw all the comments on this thread on first, just helped you out with your second problem. Just read them all. Ive never used the method scitunes described for calibrate: change calibrate to abs(accelerometer.x)

what ive always done is change calibrate to game.Accelerometer.X *-1

Try that for your calibrate attribute, and see if you can adjust the sensitivity then. Might not make a differnce worth a shot though.

The 0.1 or 0.000000000001 won't make a diffference for the accelerometer being registered. It is the accelerate behavior amount in the rule that makes the difference.
