Accelerometer Movement (Is the Wiki Now Wrong)

Jel

I've gone back to some old projects to update them to iOS4 and the accelerometer seems to be the opposite of what it use to be in GS 0.?

I though it may just be my games but I've just create a test accelerometer game and they do not match the Wiki's way of doing it http://gamesalad.com/wiki/how_tos:gsc_key_and_accelerometer_movement

I.E. to go up game.accel X > 0.1 works correctly but in the Wiki it says to use game.accel X < -0.1

I've uploaded a very simple accelerometer test game --> http://gamesalad.com/game/play/82097.
If you look at the rules instide Actor 1 you'll see that they are the opposite of what the Wiki says to do but the actor moves in the correct way.

Any help on this would be very much appreciated as I've tried the new rules in one of my games and although the actor moves in the correct way all the animation is wrong and would involve a lot of work to fix. Is there something simple I missed along the way with all the GS updates as I haven't worked on a project since April/May?

Didn't you alreAdy start a thread on this?
Did you check auto rotate off and is your format landscape or portrait as that makes a difference
GS keeps x as side to side when in portrait mode and y top to bottom but when you turn the device landscape with button on left x and y are still at the same they also rotate clockwise so now the - x up is the top and the +x is the bottom - y is the left and + y is the right

Hi Chaser,

Thanks for the reply and sorry if this is a double post with a different title but I could feel the other one wasn't going anywhere.

Did you get a chance to look at my web demo game? How did it work on your device ?

I understand what the Wiki states and have been using those rules for the last year but now for some reason it work the opposite way round. So in landscape view +y is left and -y is right. I've tested this with another accelerometer demo ( http://gamesalad.com/game/play/29870 ) and it confirms that when tilted left it's +y and when tilted right -y.

i downloaded your test and its cracking me up because no matter what changes i make to the directions be it if X is > .1 move 270 or X is > .1 move 90 it isnt changing yet i open my Ghost Words project which i updated only 3 weeks ago i have it as X > .1 move 270 X < -.1 move 90. Y > .1 move 0 and Y < -.1 move 180the one difference i played with in my project because yours would not change regardless of what i did is that i have an
(any)
if keyboard "down" is down
X > .1 move 270

if keyboard up is down
then X < -.1 move 90

and so on for the Y
all your device orientations and scene are the same as mine
i think your project is corrupt or my GS wont register the changes i make on your test

just uploaded accelerometer test chaser
its in shared and my profile

Thanks Chaser for confirming that something's up with either my projects or my GS. I downloaded another GS Creator and still the same problem so it makes me think there are some corrupt preferences somewhere or something else going on.

I take it no one else has experienced this ?

Thanks for the upload Chaser, I tested it in GS Viewer and still the same problem. Tilt right ball goes left, tilt left the ball goes right...

I think I'm going to have to contact the developers directly.

Chaser

Yeah because mine worked fine in my side but yours didn't. But if now mine does not work on yours then I think your GS is screwed.

Jel

Problem solved, here is a copy of the letter I sent to CodeMonkey.

Thanks CodeMonkey,

Your Accelerometer Test demo cleared it up for me with it's rotation settings. Although I did try changing the orientation of my game previously what stumped me was that you need to physically rotate the device the first time for the rotation to trigger and then it fixes.

Anyway seems to be all good now. Thanks again for the help.

Chaser

thats crazy considering i also tested you demo on my device and rotated it several times but it still acted the same way.
