Physics for iOS (Dynamiks Xtra) uses PhysX SDK v3.2.0 from Nvidia while the current desktop version uses PhysX SDK v2.7.2. Since there are slight changes in the interfaces in the newer version of PhysX SDK, we are providing a new version of Dynamiks Xtra for Mac.
Two versions of Dynamiks Xtra have been enabled for use on MAC, Dynamiks.xtra and Dynamiks_320.xtra.
The Dynamiks_320.xtra can be used while authoring movies for iOS platform to preview how the end result looks on idevices.
Note: Dynamiks_320 uses latest PhysX engine which supports iOS. Movies with old physics cast member will throw errors when played on iOS. To ensure that physics created using Director 11.5 to play on iOS:
- Delete the old physics cast member
- Import the new physics cast member from Insert-> Media Element > Physics_320
- Republish the movie
The following are the iOS-specific changes in the Physics engine:
For rigid body methods such as applyForce(vector vForce, vector vPosition), you may have to manipulate the vForce vector and specify higher values to generate the same effect as the previous builds.
