问题 I'm porting my android game to osx I'm having problems on devices with retina display, the sprites are either unnececary scaled or the sprites offset are scaled and not in place, I'd like to have a possibility to control this by myself. Is it possible to work in retina mode without scale factor, can I somehow enable usage of a full screen 960x640 and with scale factor still set to 1.0? Could you please tell me how can I do it? 回答1: You can disable retinal display in AppDelegate.cpp file. In

问题 My question may not be very correct, but let me describe it in details. I use cocos2d-x (renders using opengl-es 2) game engine to show images on Android device. In some cases when image dimensions are very large the images are not being displayed. They just get skipped. But I see that the size of the image is smaller then the size of my device VRAM. Checked with this method with /dev/graphics/fb0 : How to measure VRAM consumption on Android?. So my file size is 532,042 bytes , its dimension

问题 I'm doing a platformer game using cocos2d-x v3 in c++, where the maps are usually very large, the visible screen follows the object through the map. Let's say I want to show a sprite in the top right corner of the screen and it would be in this position even when the screen is following the object. Using the object position doesn't do it. Is there a way to show a sprite or whatever in the screen and it would be in the screen even when the screen is moving? Ps. I'm super noob in game

问题 I am new to using Cocos2d-X and am just experimenting using JNI in my application. So here is my java code public class JNITest { public static native void printSomething(); public static void printSomethingFromJava(){ printSomething(); } } I use javah to generate a header file, and implement a C function in my MyScene.cpp file void notify(){ CCNotificationCenter::sharedNotificationCenter()->postNotification("hello",NULL); } extern "C" { void Java_com_nbs_test_JNITest_printSomething(JNIEnv *,

问题 We are creating an SDK that is used in Cocos2d-x games (on Android/iOS). As part of development, we have setup a test framework for running various tests on a real device (Android only at the moment). One specific test needs to kill the app and launch it again. It seems that Cocos2d-x does not provide any API for exiting (or killing) the running app. Some online resources suggested that people have used the call to exit(0) . Is there any way to exit the game from Cocos2d-x ? Calling exit(0)
