Aircraft vs. 03 aircraft firing bullets, adding enemies

Aircraft fired bullets:

The bomb screen is the essence of the Thunder game. This requires control of the trajectory of the bullet.

Make one of the simplest bullet launches, and then add a variety of barrage (in fact, the main thing is to study the bullet screen)

said is the simplest, in fact, is the most common bullet launch, producing a bullet to move OK up.

method: Make a bullet launch timer, produce bullets, bullets do Moveby Action is OK up.

Code:

GameLayer.cpp

void Gamelayer::fireschedule (float dt) {Size screensize = director::getinstance ()->getwinsize (); VEC2 Crepos = M_pplayerplane->getposition ();//The initial position of the bullet float flytime = 1.0f; Sprite * Pbullet = sprite::create ("bullet1.png");p bullet->setposition (Crepos); AddChild (Pbullet,zorder_bullet); Flytime = ((screensize.height-crepos.y)/screensize.height) *flytime;//The time of movement is related to the distance of the launch, Pbullet->runaction ( Sequence::create (Moveby::create (FLYTIME,VEC2 (0,SCREENSIZE.HEIGHT-CREPOS.Y)), Removeself::create (True), nullptr)) ;}

The enemy creates a new class, because the enemy may need to have some of their own properties to follow.

Enermysprite . h

#ifndef _enermy_sprite_h_#define _enermy_sprite_h_#include "Cocos2d.h" USING_NS_CC; typedef enum {Kenermytypenone = 0, Kenermytype1,kenermytype2,kenermytype3,kenermytype4,}enermytype;class Enermysprite:public Sprite{public:static Enermysprite * Createbytype (enermytype type); static const char * GETIMAGENAMEBYTYPE (enermytype type);p ublic: Enermysprite (); ~enermysprite ();p rivate:}; #endif

Enermysprite . cpp

#include "EnermySprite.h" Enermysprite * enermysprite::createbytype (enermytype type) {const char * pimage = Getimagenamebytype (type); Enermysprite * PRet = new Enermysprite ();p ret->initwithfile (pimage);p ret->autorelease (); return pRet;} const char * enermysprite::getimagenamebytype (Enermytype type) {Const char* pimagename = Nullptr;switch (type) {case Kenermytype1:pimagename = "Enemy1.png"; break;case kenermytype2:pimagename = "Enemy2.png"; Break;case kEnermyType3: Pimagename = "Enemy3.png"; break;case kenermytype4:pimagename = "enemy4.png"; break;default:break;} return pimagename;} Enermysprite::enermysprite () {}enermysprite::~enermysprite () {}

To add to the game:

GameLayer.h

void Gamelayer::createeneschedule (float dt) {int ran = ccrandom_0_1 () * 4 + 1; Enermytype type; switch (RAN) {case 1:type = kenermytype1;break;case 2:type = kenermytype2;break;case 3:type = kEnermyType3 ; Break;case 4:type = Kenermytype4;break;default:break;} Auto Pene = Enermysprite::createbytype (type), float x = ccrandom_0_1 () * (Director::getinstance ()->getwinsize (). Width-pene->getboundingbox (). Size.width/2) + Pene->getboundingbox (). Size.width/2;float y = Director::getInsta NCE ()->getwinsize (). Height + pene->getboundingbox (). size.height/2; float flytime = 2.0f;p ene->runaction ( Sequence::create (Moveby::create (FLYTIME,VEC2 (0,-(Director::getinstance ()->getwinsize (). Height + pEne-> Getboundingbox () size.height)), Callfuncn::create (Cc_callback_1 (gamelayer::enermymoveendcallback,this)), Removeself::create (True), nullptr), AddChild (pene);p ene->setposition (x, y); M_penermyvec.pushback (pene);} void Gamelayer::enermymoveendcallback (Node * pnode) {Enermysprite * penermy = dynamic_cast<enermysprite*> (Pnode); M_penermyvec.eraseobject (penermy);} 

again a timer, remember to add an enemy's v Ector to store the enemy.
