Cocos2d-x text rendering

Text rendering:

The CCLabelAtlas, CCLabelBMFont, and CCLabelTTF classes inherit the CCLabelProtocol class, that is, you can use system words or customize the rendering font.

The CCLabelAtlas class uses images as a text method and can be directly defined through images.

CCLabelAtlas * label0 = CCLabelAtlas: create ("ASDE test", "tuffy_bold_italic-charmap.png", 46, 64, ''); // Parameter order: to display characters, image paths, character width, character height, starting character label0-> setPosition (ccp (100,200); label0-> setOpacity (200); this-> addChild (label0 ); CCLabelAtlas * label2 = CCLabelAtlas: create ("456789123", "tuffy_bold_italic-charmap.png", 46, 64, ''); label2-> setPosition (ccp (visibleSize. width/2, visibleSize. height/2); label2-> setOpacity (200); this-> addChild (label2); // CCActionInterval * ac = CCFadeOut: create (1.2f ); CCActionInterval * ac2 = ac-> reverse (); label2-> runAction (CCRepeatForever: create (CCSequence: create (ac, ac2, NULL ))); // use the description of the plist configuration file. You can modify the configuration file information as needed, including the image path, character width and height, and the starting character "CCLabelAtlas * label1 = CCLabelAtlas :: create ("wer vbn ",". /tuffy_bold_italic-charmap.plist "); // Parameter order: to display characters, plist file path label1-> setPosition (ccp (10,100); label1-> setOpacity (200 ); this-> addChild (label1 );

The CCLabelTTF class implements font labels through system words.

CCLabelTTF * ttf = CCLabelTTF: create ("hello world", "Helvetica", 30, ccp (320, 30), kCCTextAlignmentLeft); // Parameter order: to display characters, font Name, font size, range size, alignment mode [kCCTextAlignmentLeft (left alignment) kCCTextAlignmentCenter (center aligment)] ttf-> setPosition (ccp (300,400 )); this-> addChild (ttf );

The CCTextFieldTTF class input box uses a text tag to inherit the CCLabelTTF class.

CCTextFieldTTF *pTest = CCTextFieldTTF::textFieldWithPlaceHolder("
 
  ", "STHeitiTC-Light",40 );pTest->setPosition(ccp(300, 500));this->addChild(pTest);
 

Each word in the CCLabelBMFont class is an genie. Each word can define an action and supports FNT files.

CCLabelBMFont * label = CCLabelBMFont: create ("Bitmap Font Atlas Xub", "fonts/bitmapFontTest. fnt "); addChild (label); CCSize s = CCDirector: sharedDirector ()-> getWinSize (); label-> setPosition (ccp (s. width/2-200, s. height/2); label-> setAnchorPoint (ccp (0.5f, 0.5f); CCSprite * BChar = (CCSprite *) label-> getChildByTag (0 ); // obtain the 1st character 'B' CCSprite * FChar = (CCSprite *) label-> getChildByTag (7); // obtain the 7th character 'F' CCSprite * AChar = (CCSprite *) label-> getChildByTag (12); // obtain the 12th character 'a' CCSprite * XChar = (CCSprite *) label-> getChildByTag (18 ); // obtain the 12th character 'a' // create action for the character CCActionInterval * rotate = CCRotateBy: create (2,360); CCAction * rot_4ever = CCRepeatForever: create (rotate ); CCActionInterval * scale = CCScaleBy: create (2, 1.5f); CCActionInterval * scale_back = scale-> reverse (); CCSequence * scale_seq = CCSequence: create (scale, scale_back, NULL); CCAction * scale_4ever = CCRepeatForever: create (scale_seq); CCActionInterval * jump = CCJumpBy: create (0.5f, CCPointZero, 60, 1); CCAction * jump_4ever = cursor :: create (jump); CCActionInterval * fade_out = CCFadeOut: create (1); CCActionInterval * fade_in = CCFadeIn: create (1); CCSequence * seq = CCSequence: create (fade_out, fade_in, NULL); CCAction * fade_4ever = CCRepeatForever: create (seq); CCActionInterval * by = CCMoveBy: create (1.0f, ccp (300,300 )); CCActionInterval * by2 = by-> reverse (); CCSequence * seq_by = CCSequence: create (by, by2, NULL); CCAction * ac_by = CCRepeatForever: create (seq_by ); BChar-> runAction (rot_4ever); BChar-> runAction (scale_4ever); FChar-> runAction (jump_4ever); AChar-> runAction (fade_4ever); XChar-> runAction (ac_by );
