PhoneGap Rotation Orientation Wackiness

[Joe Hakooz 6 Likes (Newbie)]

This is probably an edge case so it's not a huge deal, but thought I would report this as I spent the past few hours figuring it out...

 

My PhoneGap (Cordova) iPad app allows orientation changing in all four directions.

1 = home button bottom

2 = home button top

3 = home button right

4 = home button left

 

For each orientation I use GSAP to rotate an element so that the top of that element always points to the home button.

 

This worked in all variations except when rotating from 3 or 4 to 1.

When rotating to orientation 1 I was using rotation:0

 

Changing rotation:0 to rotation:360 resolved the issue. Crazy right?

 

Hope that helps someone...

Hi Joe,

 

Thanks for logging your experience here. You may save someone a few hours of hair-pulling some day.

Have you tried using shortRotation so that it goes in the shortest direction? Just a thought.

Short Rotation seems to work great. But when I went to test the previous way (that was acting wacky) I wasn't able to replicate the issue. So now I'm not sure what the heck happened.

 

Let's chalk this up to programmer error. I'll post here if there are any other developments...

Conclusion...

 

Ok, I'm a dumbass... The problem was the event I was calling in Objective C was sending the incorrect orientation.

 

Not related in any way to GSAP.

Glad to hear you figured it out. Thanks for letting us know!
