Cocos2d-x tower defense (2) Let the monsters run

Previously Used version is 2.0.1 version, and later with 2.1.1 re-write a part, now brand new start, with the latest version, cocos2d-x-3.0beta, this version and the previous changes quite large.

 

This is the background material.

 

Program Implementation Method:

 

// ================ Attach a background map ============== auto bg = TMXTiledMap: create (bg. tmx); bg-> setPosition (Point (0, 0); this-> addChild (bg, 0 );

 

In this way, we can load the edited map to the scene, and then modify the bg. tmx file to record our route.

 

 

Method for initializing the route in the program:

 

auto map  = TMXTiledMap::create(bg.tmx);auto group = map->getObjectGroup(path);auto& objects = group->getObjects();for (auto& obj : objects){ValueMap& dict = obj.asValueMap();int x = dict[x].asInt();int y = 480 - dict[y].asInt();wayPoint.push_back(Point(x,y));wayCount++;}

 

The wayPoint of the container records the points in the tmx file.

Well, now we have a background, a route, and a monster.

Read method:

 

void Enemy::uploadEnemy(){//RightMove()Vector
 
  tempRightMove;for (int i = 8; i < 12; i++){tempRightMove.pushBack(Myframes[i]);}Animation* aniRightMove = Animation::createWithSpriteFrames(tempRightMove,0.2f);actionRightMove = Animate::create(aniRightMove);actionRightMove->retain();//LeftMove()Vector
  
   tempLeftMove;for (int i = 4; i < 8; i++){tempLeftMove.pushBack(Myframes[i]);}Animation* aniLeftMove = Animation::createWithSpriteFrames(tempLeftMove,0.2f);actionLeftMove = Animate::create(aniLeftMove);actionLeftMove->retain();//UpMove()Vector
   
    tempUpMove;for (int i = 12; i < 16; i++){tempUpMove.pushBack(Myframes[i]);}Animation* aniUpMove = Animation::createWithSpriteFrames(tempUpMove,0.2f);actionUpMove = Animate::create(aniUpMove);actionUpMove->retain();//DownMove()Vector
    
     tempDownMove;for (int i = 0; i < 4; i++){tempDownMove.pushBack(Myframes[i]);}Animation* aniDownMove = Animation::createWithSpriteFrames(tempDownMove,0.2f);actionDownMove = Animate::create(aniDownMove);actionDownMove->retain();}
    
   
  
 

 

Create a Monster:

 

Void GameScene: addEnemy () {// ================ Add a monster ================== auto enemy = Enemy :: create (); enemy-> setPosition (Tools: ConvertViewPoint (DataManage: getInstance ()-> wayPoint [0]); this-> addChild (enemy, 1 ); dataManage: getInstance ()-> v_enemy.push_back (enemy );}

 

Monster movement:

 

Void Enemy: run () {if (this-> iTurn <RoadCount-1 & this-> hp> 0) {Point point1 = DataManage: getInstance () -> wayPoint [iTurn]; Point point2 = DataManage: getInstance ()-> wayPoint [iTurn + 1]; Point p0 = Tools: ConvertViewPoint (point2 ); point p = this-> getPosition (); // frame animation if (point2.x-point1.x = 0) // vertical {if (point2.y-point1.y> = 0) {if (iChangeDire! = 1) {this-> stopAllActions (); this-> runAction (RepeatForever: create (actionDownMove); // 1 iChangeDire = 1;} p. y-= this-> speed * 1; if (p. y-p0.y <= 0) {iTurn + +; p = p0 ;}} else if (point2.y-point1.y <0) {if (iChangeDire! = 2) {this-> stopAllActions (); this-> runAction (RepeatForever: create (actionUpMove); // 2 iChangeDire = 2;} p. y + = this-> speed * 1; if (p. y-p0.y >=0) {iTurn ++; p = p0 ;}} else if (point2.y-point1.y = 0) // level {if (point2.x-point1.x> 0) {if (iChangeDire! = 3) {this-> stopAllActions (); this-> runAction (RepeatForever: create (actionRightMove); // 3 iChangeDire = 3;} p. x + = this-> speed * 1; if (p. x-p0.x> = 0) {iTurn ++; p = p0 ;}} else if (point2.x-point1.x <= 0) {if (iChangeDire! = 4) {this-> stopAllActions (); this-> runAction (RepeatForever: create (actionLeftMove); // 4 iChangeDire = 4;} p. x-= this-> speed * 1; if (p. x-p0.x <= 0) {iTurn + +; p = p0 ;}} this-> setPosition (p);} // else if (this-> iTurn> = RoadCount-1) /// {// this-> removeFromParentAndCleanup (true); // DataManage: getInstance ()-> v_enemy.erase (pos );//}}

The time when a monster appears is written in a plist.

Enable a timer in the main scenario to traverse all the monsters and make them appear and run.
