Rounded Corners Rect in Cocos 2d-x with Bezier

阅读更多关于 Rounded Corners Rect in Cocos 2d-x with Bezier

问题 Is it possible to draw a Rect with rounded corners using a DrawNode object? I think that something is possible using Bezier curves, but I have made some tries and I think I can't handle it. Looking at API I've found only these 2 functions: drawQuadBezier (const Vec2 &origin, const Vec2 &control, const Vec2 &destination, unsigned int segments, const Color4F &color) drawCubicBezier (const Vec2 &origin, const Vec2 &control1, const Vec2 &control2, const Vec2 &destination, unsigned int segments,

问题 I am getting the camera frame from the android camera Preview Callback in Byte array and pass it to jni code. As we can't use byte in c++ so i am converting it to the integer array as follows: JNIEXPORT void JNICALL Java_com_omobio_armadillo_Armadillo_onAndroidCameraFrameNative( JNIEnv* env, jobject, jbyteArray data, jint dataLen, jint width, jint height, jint bitsPerComponent) { Armadillo *armadillo = Armadillo::singleton(); jbyte *jArr = env->GetByteArrayElements(data, NULL); int dataChar

问题 I am porting my cocos2d iPhone game to android using cocos2d-x. I am now facing a problem with screen resolution: I want to use one high resolution image in my game which should be supportable by all screens lower then a given resolution.

Crash in Android Native while changing to new Activity

阅读更多关于 Crash in Android Native while changing to new Activity

问题 My application is unable to open OpenFeint dashboard methods. The implementation of the native c++ libraries uses cocos2d-x as a graphic library, but it has a handler and a wrapper to allow the use of OpenFeint functions. OpenFeint initialization and non-activity methods work correctly. When UI dashboard functions such as openLaderBoards or openAchievements are called either from a Jni call or in the Java onCreate initialization, the application crashes. EDIT: I have tested and it happens to

问题 I am trying to save a high score integer to the user's Android system, so that it can persist throughout all game-play experience. I have read that using Cocos2D-X one can use NSUserDefaults but this doesn't seem to be available in the Cocos2D-JS API at all. Anyone has any experience with this, is there any other efficient way how to tackle this issue? 回答1: When using Cocos2D-JS for compiling native apps, you can simply use localStorage just like if you were running your game in the browser
