Part 2 Title Animation

Create a new project under visula studio

Tool class ConstUtil. h. This file mainly defines some image resources, strings, fonts, etc.

# Ifndef _ CONSTUTIL_H __# define _ CONSTUTIL_H _ // defines four image resources of chengmai technology, use the company name for animation # define CHENG_IMAGE "cheng.png" # define MAI_IMAGE "mai.png" # define KE_IMAGE "ke.png" # define JI_IMAGE "ji.png" # endif

Create SplashScene. cpp and SplashScene. H files

This H file mainly defines some methods ............................... Const double MOVE_SPLEED = 0.5f; // animation playback speed void moveKeSpriteToLeft (); // define the void moveMaiSpriteToLeft () method for moving the ke.png genie to the left (); // define the method void initMoveSprite () for moving the mai.png genie to the left; // initialize the image method void startMoveSprite (float dt); // start the method void gotoMenuScene (); // After the animation ends, enter the MenuScene scene method void spriteFadeOut (); // The animation gradually disappears ............................... Sprite * mai_Sprite; // main.png image Sprite * ke_Sprite; // ke.png image Sprite * ji_Sprite; // ji.png image Sprite * cheng_Sprite; // cheng.png image Sprite Size visibleSize; // window Size spriteSize; // the Size of each image

The main content of SplashScene. cpp is as follows:

Bool SplashScene: init () {if (! Layer: init () {return false;} visibleSize = Director: getInstance ()-> getVisibleSize (); // initialize the window size variable Vec2 origin = Director :: getInstance ()-> getVisibleOrigin (); initMoveSprite (); // initialize the animation genie method scheduleOnce (schedule_selector (SplashScene: startMoveSprite), ONE_SECOND ); // return true after the animation starts playing for 1 second in the scenario ;}

The initMoveSprite () method is as follows: Call the Sprite: create method to create four genie mai_Sprite = Sprite: create (MAI_IMAGE );.................... SpriteSize = mai_Sprite-> getContentSize (); // assign a value to the animation size. The size of each animation is the same. // Place the sprite image mai_Sprite-> setPosition (ccp (visibleSize. width/2-(2 * spriteSize. width), visibleSize. height/2); ke_Sprite-> setPosition (ccp (visibleSize. width/2-spriteSize. width, visibleSize. height/2); ji_Sprite-> setPosition (ccp (visibleSize. width/2, visibleSize. height/2); cheng_Sprite-> setPosition (ccp (visibleSize. width/2 + spriteSize. width, visibleSize. height/2); set all the genie anchor points to (0, 0.5), so that the four images can be arranged in the center of the window mai_Spr Ite-> setAnchorPoint (ccp (0, 0.5 ));........................ This-> addChild (mai_Sprite); // Add the genie to the scenario

Start playing the animation:

Void SplashScene: startMoveSprite (float dt) {// The animation starts from the right. The last Genie, cheng, first moves the position MoveBy * moveChengToLeft1 = MoveBy :: create (MOVE_SPLEED, ccp (-spriteSize. width, 0); cheng_Sprite-> runAction (moveChengToLeft1); // move the Tianji field from left to right, the two animations are equivalent to the positions MoveBy * moveJiToright = MoveBy: create (MOVE_SPLEED, ccp (spriteSize. width, 0); CallFunc * callFunc = CallFunc: create (CC_CALLBACK_0 (SplashScene: moveKeSpriteToLeft, this); // call the moveKeSpriteToLeft () method after the animation ends, start the animated ji_Sprite of the genie ke-> runAction (Sequence: create (moveJiToright, callFunc, NULL ));}

Genie ke Animation:

Void SplashScene: moveKeSpriteToLeft () {// The genie cheng moves the position MoveBy * moveChengToLeft2 = MoveBy: create (MOVE_SPLEED, ccp (-spriteSize. width, 0); cheng_Sprite-> runAction (moveChengToLeft2); // The sprke moves a position from left to right and switches the position MoveBy * ke_Sprite_MoveBy = MoveBy :: create (MOVE_SPLEED, ccp (spriteSize. width, 0); CallFunc * callFunc2 = CallFunc: create (CC_CALLBACK_0 (SplashScene: moveMaiSpriteToLeft, this); // call moveMaiSpriteToLeft () method after the animation ends, start the animation ke_Sprite-> runAction (Sequence: create (ke_Sprite_MoveBy, callFunc2, NULL) of the genie mai ));}

Genie mai Animation:

Void SplashScene: moveMaiSpriteToLeft () {// The genie cheng moves another position from right to left. MoveBy * moveChengToLeft3 = MoveBy: create (MOVE_SPLEED, ccp (-spriteSize. width, 0); cheng_Sprite-> runAction (moveChengToLeft3); // The genie mai moves a position from left to right, and switches the position MoveBy * mai_Sprite_MoveBy = MoveBy :: create (MOVE_SPLEED, ccp (spriteSize. width, 0); CallFunc * callFunc3 = CallFunc: create (CC_CALLBACK_0 (SplashScene: spriteFadeOut, this); // call the spriteFadeOut () method after the genie mai animation ends, animation mai_Sprite-> runAction (Sequence: create (mai_Sprite_MoveBy, callFunc3, NULL) that begins scene disappearance ));}

Scene disappearance Animation:

Void SplashScene: spriteFadeOut () {// defines four deprecated FadeOut animations. The duration is 2 seconds. FadeOut * fadeOut1 = FadeOut: create (ONE_SECOND * 2 ); fadeOut * fadeOut2 = FadeOut: create (ONE_SECOND * 2); FadeOut * fadeOut3 = FadeOut: create (ONE_SECOND * 2); FadeOut * fadeOut4 = FadeOut :: create (ONE_SECOND * 2); mai_Sprite-> runAction (fadeOut1); ke_Sprite-> runAction (fadeOut2); ji_Sprite-> runAction (fadeOut3); CallFunc * callFunc4 = CallFunc :: create (CC_CALLBACK_0 (SplashScene: gotoMenuScene, this); // call the gotoMenuScene () method after the animation ends to enter the MenuScene scene interface cheng_Sprite-> runAction (Sequence: create, callFunc4, NULL ));}

Go to the scenario method gotoMenuScene () and print only the log temporarily.

Void SplashScene: gotoMenuScene ()

{

Log ("gotoMenuScene ");

Director: getInstance ()-> replaceScene (MenuScene: createScene ());

}

The process is simple, as shown in the following flowchart.

The title animation ends. To be continued ................
