问题 I'm trying to build a simple side scroller with an airplane being the player. As such, I want to build simple flight controls with simple but realistic-feeling physics. I'm making use of cocos2D and Box2D. I have a basic system working, but just can't get the physics feeling correct. I am applying force to the plane (which is a b2CircleShape ) based on the user's input. So, basically, if the user pushes up, body_->ApplyForce(b2Vec2(10,30), body_->GetPosition()) is called. Similarly, for down

问题 I'm beginner in Cocos2d. I have a sprite, and I want to ignore touch on transparent area of that sprite. I'm aware of this answer Cocos2d 2.0 - Ignoring touches to transparent areas of layers/sprites, and also this great article http://www.learn-cocos2d.com/2011/12/fast-pixelperfect-collision-detection-cocos2d-code-1of2/. I was able to make it work with KKPixelMaskSprite, but only when sprite is used from file, but not from batch node. Whenever I use batch node (Sprite sheet), to get sprite ,

问题 I've got retina tile maps working, 15x10 tiles, of 64x64 tiles. problem is for non-retina devices I will need to make a 15x10 tiles of 32x32 tiles. I don't want to recreate the Tile, is it just a case of changing the XML (.tmx) file? Is there an automated tool or another way around this? I've been looking online but not getting too much help. Thanks 回答1: You have to update the TMX file and scale certain attributes. Unless your TMX map is very simple this will be a tedious and error-prone task

问题 How can I draw filled poly in Cocos2D framework? Code below draws poly but without antialiasing.What should I change? void ccFillPoly( CGPoint *poli, int points, BOOL closePolygon ) { // Default GL states: GL_TEXTURE_2D, GL_VERTEX_ARRAY, GL_COLOR_ARRAY, GL_TEXTURE_COORD_ARRAY // Needed states: GL_VERTEX_ARRAY, // Unneeded states: GL_TEXTURE_2D, GL_TEXTURE_COORD_ARRAY, GL_COLOR_ARRAY glDisable(GL_TEXTURE_2D); glDisableClientState(GL_TEXTURE_COORD_ARRAY); glDisableClientState(GL_COLOR_ARRAY);

问题 Hi i want to develop game like 'Doodle jump'.But i have some problem with the following features- 1.How to move background scene/image. 2.How to detect collision between object.Is it needed a physics engine like box2d or i should just use manual collision. 3.what should be the size of the background image. 4.In fact i have no idea how does background move .So i need a explanation from someone. 回答1: Background Movement A) You could create a TMX Tilemap and then make a very high Tiled-Map. B)

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . I have had multiple snapshot and even reverting to them this thing just won't compile. It gives me over 40 errors! What can I do? I didn't change anything at all. As I say, even reverting to old snapshot doesn't
