问题 It is somewhat an awkward situation right now. When I run my project directly from Xcode to my device it runs perfect without any crashs. But when I create an ipa file of that project and install that ipa into my device by using iTunes, only for the first time when I launch my gameplay screen it crashes, later on when I starts my gameplay it runs fine. Remember, my gameplay starts after the user navigates 2 initial screens which works pretty fine in either conditions. (i.e running from Xcode

问题 I've been searching around for a while, but it's been hard to find a definit list of available suffixes which you can use for multi resolution support, if there is any? That is, loading images in a dimension depending on what device you're on. Especially for the interface. I know that the "-hd" suffix exists for ipad retina display support, but besides that it would also be nice if there is any suffix for regular iPad resolution as well as an iPhone suffix when the game is loaded on an iPhone

问题 I've got a CCSprite with three animations: idle, walk and attack. I want to switch between idle and walk depending on whether or not the sprite is moving (if the joystick is beeing used). All of this works great. For the attacking animation, I want it to run once, and then return to the previous animation when done (ex.: idle) how do I detect when the animation is done? thanks, Dave 回答1: Alright, so here's what i've done, and it works, although I have no clue if its the right or the best way:

问题 In my cocos2d game i can't change size of uialertview, i have changed statusbarorientation to landscape, and now want to init alertview with frame, and initwithframe method does not affect the size of alertview, every time the size of alert is the same, is there any way to change it ? 回答1: Here is what i did. Create your uialertview in your controller. then override the following class within your controller (after setting the uialertview delegate ... ie. myalertview.delegate=viewcontroller)

问题 I'm localizing my app which is cocos2d so there are no nib files, I'm localizing a label which is fine but want to check the device language to set an exact font and font size for each language. In short I want to do it as the following: If (device.language == en) { Set font to "fontname" and "fontsize" to x; } else { set it to "another font name" and font size to y; } How to check that the device language/settings is set to an exact language? 回答1: You can use: [[NSLocale preferredLanguages]

问题 I have an issue when I subclass a type which bind an obj-C type. In some cases, it fails at construction time. I can reproduce this right now with the cocos2d bindings and CCSprite. Here's my subclass public class MySprite : CCSprite { public MySprite (string filename) : base (filename) {} } When I instantiate it, it fails: Stacktrace: at (wrapper managed-to-native) MonoTouch.ObjCRuntime.Messaging.void_objc_msgSendSuper_IntPtr (intptr,intptr,intptr) <IL 0x00025, 0xffffffff> at MonoTouch

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow.

问题 How to move the ball dependent on touch angle and make the ball reflect if it touches the wall? CGFloat diffX = ballImg.position.x - tchLoc.x; CGFloat diffY = ballImg.position.y - tchLoc.y; CGFloat angleRadian = atan2f(diffY, diffX); float angleDegrees=CC_RADIANS_TO_DEGREES(angleRadian); 回答1: I am considering that you have taken your ball as a sprite. so in touchesBegan you will get the touch location and then you can use that location points in CCMoveTo action to move your ball which is a
