You can find many methods for rotating rectangular Collision Detection on the Internet.ArticleThis collision detection was analyzed: the OBB collision detection. This article is mainly to add some of its own analysis of the details, combined with some other information on the Internet on the rotating rectangular collision detection, and discuss with you the technical details of the implementation.
First, we recommend a reference material, which prov
Android provides several options for storing persistent application data, one of which is external storage (/sdcard,/mnt/sdcard ). External Storage includes a micro-or standard-sized SD card inside the device, an Android device memory card mounted to the PC, and an Android/obb directory.
In versions earlier than Android, the files stored in external storage are world-readable (which can be read by any user) and world-writable (which can be written by

Then, use the cp in the busybox to transfer the busybox cp to/system/bin. Now it seems like linux. When compiling busybox at www.2cto.co

Rectangular border box
Another common geometric element used to define an object is a rectangular boundary frame, which can be aligned with the axis or in any direction. The axis alignment rectangular boundary box has a limit that its edges must be perpendicular to the coordinate axis. The abbreviation AABB is often used to represent axially aligned bounding box (axis-aligned rectangular boundary box), and
animation, all actions are well processed and bounding_box is also well obtained. the corresponding interface is 1 armature: getAnimation (): play (action_const_name) 2 3 local bounding_box = armature: getBoundingBox () then we can easily use AABB or OBB for collision detection and set up AI and other miscellaneous things. we all know that the use of sequence frames is not so convenient. In the combination of .png and Plist, action processing needs t

Introduction
In 3D collision detection, in order to speed up the efficiency of collision detection and reduce unnecessary collision detection, basic geometry is used as the bounding body of the object (bounding Volume, BV) for testing. Collision detection of the basic bounding body is relatively inexpensive and much easier,
