Coco2d learning day01 genie Analysis

Day01 notes using namespace cocos2d; = using_ns_cc; generally, the following # ifndef _ mylayer_h __# DEFINE _ mylayer_h _ --------------- is generally added to the header file to the macro: public cclayer generally adds a class to inherit cclayer: Init (); cclabelttf * plabel = cclabelttf: Create ("Sunda", "Arial", 36 ); // define a lableaddchild (plabel, 1); // Add a lableccsize size = ccdirector: shareddirector ()-> getwinsize () to the image scene (); // obtain the current coordinate plabel-> setposition (CCP (size. width/2, size. height/2); // set the position of the lable on the stage // Add an image ccmenuitemimage: Create ("closenormal.png", "closeselected.png", this, menu_selector (mylist:: menuclosecallback); // The first vertex number is the displayed image; // The second vertex number is the image in the vertex; // The third vertex number is the fourth vertex number triggered when you click. ccmenuitemimage * inage = ccmenuitemimage: Create ("closenormal.png", "closeselected.png", this, menu_selector (mylist :: menuclosecallback); ccmenu * pmenu = ccmenu: Create (inage, null); pmenu-> setposition (); // The coordinate addchild (pmenu, 1) of the image ); // display // Add a background ccsprite * psprite = ccsprite: Create ("helloworld.png"); // Add an image psprite-> setposition (CCP (size. width/2, size. height/2); // set the position of the image addchild (psprite, 0); // return true; settouchenabled (true ); support for touch. If you do not want to write, do not approve of the settouchmode (kcctouchesallatonce); multi-point touch: for example, what is the settouchmode (kcctouchesonebyone) When both hands are pressed on the mobile phone screen: for example, what bool cctouchbegan (cctouch * ptouch, ccevent * pevent) is on the screen of a single-handed mobile phone? // void cctouchmoved (cctouch * ptouch, ccevent * pevent) when your finger is pressed ); // void cctouchended (cctouch * ptouch, ccevent * pevent) when your fingers move and press; // void cctouchcancelled (cctouch * ptouch, ccevent * pevent); // when you call, the genie creates ccsprite * sprite = ccsprite: Create ("1/furnace/jt.png "); use an image to directly create ccsprite * sprite = ccsprite: Create ("1/furnace/jt.png", ccrectmake (, 20, 20 )); // use the same image, but use some ccrectmake (the starting point of X, the starting point of Y, the end point of X, and the end point of Y) addchild (sprite ); ccsize size = ccdirector: shareddirector ()-> getwinsize (); // obtain the size of the stage sprite-> setposition (CCP (size. width/2, size. height/2); // the location where the genie is sent // texture attribute cctexture2d * texture = cctexturecache: sharedtexturecache ()-> addimage ("1/furnace/jt.png "); // create a texture, put it in the texture cache, and return the cached object ccsprite * sprite = ccsprite: createwithtexture (texture); // It is equivalent to sending the image to the memory, multiple ccsprite * sprite = ccsprite: createwithtexture (texture, ccrectmake (, 20, 20 )); // The same image is used, but some ccrectmake (the starting point of X, the starting point of Y, the end point of X, and the end point of Y) ccspriteframe * frame = ccspriteframe :: createwithtexture (texture, ccrectmake (100,100,); // The needle is part of the texture ccsprite * sprite = ccsprite: Create ("images/blocks.png "); // The URL for creating a Sprite image must be images/blocks.png addchild (sprite); sprite-> setposition (CCP (100,100); // The base point must be in the lower right corner, sprite-> setanchorpoint (CCP (0.5); // 1.
