CCSprite*background=[CCSpritespriteWithFile:@"bj00.jpg"]; background.position=ccp(winSize.width*0.5,winSize.height*0.5); [selfaddChild:backgroundz:0]; //添加能量槽 CCSprite*engryBox=[CCSpritespriteWithFile:@"ui_2p_004.png"];

cannnon.position=ccp(winSize.width/2,30); cannnon.scale=cannon_scale; cannnon.cannonType=nomal; [cannonSheetaddChild:cannnon]; //添加“＋”，“－”按钮(待改) [CCMenuItemFontsetFontSize:32]; [CCMenuItemFontsetFontName:@"Arial"];

[addMenualignItemsVertically]; }触摸事件模块要点：子弹、大炮的跟随转向，子弹射出速度设置，越界判定（移动出画面） -(void)setAngle:(CGPoint)pointsprite:(CCSprite*)sp { //CCLOG(@"setAngle"); //设置“旋转角度” intoffX=point.x-cannnon.position.x; intoffY=point.y-cannnon.position.y; if(offY<=0){ return; } floatratio=(float)offY/(float)offX; //直角三角形 floatangle=atanf(ratio)/M_PI*180; //三角形正切值获得角度 if(angle<0){ cannnon.rotation=-(90+angle); //设置武器旋转角度 sp.rotation=cannnon.rotation; }elseif(angle>0){ cannnon.rotation=90-angle; sp.rotation=cannnon.rotation; } } #pragmatouchmenthed -(void)ccTouchesBegan:(NSSet*)toucheswithEvent:(UIEvent*)event { for(UITouch*touchintouches) { CGPointpos=[touchlocationInView:touch.view]; pos=[[CCDirectorsharedDirector]convertToGL:pos]; if(pos.y<=cannnon.position.y){ return; } if(cannnon.cannonType==laser){ //如果当前为超级武器， }else{ [cannnonsetDisplayFrame:[[CCSpriteFrameCachesharedSpriteFrameCache]spriteFrameByName:[NSStringstringWithFormat:@"actor_cannon1_%i2.png",cannnon.cannonLevel]]]; } [selfsetAngle:possprite:nil]; } } -(void)ccTouchesMoved:(NSSet*)toucheswithEvent:(UIEvent*)event { for(UITouch*touchintouches){ CGPointpos=[touchlocationInView:touch.view]; pos=[[CCDirectorsharedDirector]convertToGL:pos];

//发射完毕还原武器 } else { //***************(待改)******************* [goldsetNumber:([goldgetNumber]-cannnon.cannonType)];//每次损耗CCBullet*bullet=[CCBulletspriteWithSpriteFrameName:[NSStringstringWithFormat:@"bullet0%i.png",cannnon.cannonLevel]]; //添加子弹 bullet.position=cannnon.position; bullet.isHit=NO; [selfsetAngle:possprite:bullet]; //Determinewherewewishtoshoottheprojectileto intrealY=winSize.height+bullet.contentSize.height*0.5; floatratio=(float)offX/(float)offY; intrealX=(realY-cannnon.position.y)*ratio+cannnon.position.x; CGPointrealDest=ccp(realX,realY); //子弹会于一个恒定的速率按照射击方向前进 intoffRealX=realX-cannnon.position.x; intoffRealY=realY-cannnon.position.y; floatlength=sqrtf((offRealX*offRealX)+(offRealY*offRealY)); //一旦我们有了距离，我们只是除以速度，以获得所需的时间。这是因为速度=距离/时间，或换句话说时间=距离/速度。 floatvelocity=240/1;//480pixels/1sec floatrealMoveDuration=length/velocity; //移除子弹的动作 CCMoveTo*move=[CCMoveToactionWithDuration:realMoveDurationposition:realDest];CCCallFuncO*removeBullet=[CCCallFuncOactionWithTarget:selfselector:@selector(removeNet:)object:bullet];

CCNet*sp=(CCNet*)sender; [bulletSheetremoveChild:spcleanup:YES]; }鱼类精灵的添加（使用纹理图集批量渲染）要点：设置鱼的的动作，鱼的随机产生-(void)updateFish{while([[fishSheetchildren]count]<maxNumberOfFish){[selfaddFish];}}-(void)addFish{ inttype=rand()%9+1; NSMutableArray*oneFish=[NSMutableArrayarray];intnumber=10; for(inti=1;i<number;i++) { [oneFishaddObject:[[CCSpriteFrameCachesharedSpriteFrameCache] spriteFrameByName:[NSStringstringWithFormat:@"fish0%i_0%i.png",type,i]]];

//添加路线 [fishrun];[fishSheetaddChild:fishz:100];}碰撞检测的处理要点：渔网与鱼，子弹和鱼的检测方式（点面触碰与面面触碰区别），鱼，网，子弹见逻辑关系（碰撞标志的设置），-(void)updateHit{CGSizewinSize=[[CCDirectorsharedDirector]winSize];CCFish*fish;CCNet*net;CCBullet*bullet;CCScaleTo*scale0=[CCScaleToactionWithDuration:0.3scale:1.1];CCScaleTo*scale1=[CCScaleToactionWithDuration:0.3scale:0.8];CCARRAY_FOREACH([bulletSheetchildren],bullet)//遍历子弹{if([bulletisHit]){continue;}if(bullet.position.x>(winSize.width+bullet.contentSize.width)||bullet.position.x<(0-bullet.contentSize.width)){continue;}CCARRAY_FOREACH([fishSheetchildren],fish){if([bulletisHit]){continue;}if(CGRectContainsPoint([fishboundingBox],bullet.position)){//子弹碰撞bullet.isHit=YES;//shownet,removebullet//CCLOG(@"removebullet");[bulletSheetremoveChild:bulletcleanup:NO];//CCLOG(@"removeover");//添加网CCNet*netCatch=[CCNetspriteWithSpriteFrameName:[NSStringstringWithFormat:@"net0%i.png",cannonLevel]];netCatch.position=bullet.position;[netSheetaddChild:netCatch];//CCLOG(@"addnetover");//网的动作CCCallFuncO*scaleNetAfterShow=[CCCallFuncOactionWithTarget:selfselector:@selector(afterShowNet:)object:netCatch];CCSequence*netSequence=[CCSequenceactions:scale0,scale1,scale0,scale1,scaleNetAfterShow,nil];[netCatchrunAction:netSequence];//CCLOG(@"addnetover");}}}CCARRAY_FOREACH([netSheetchildren],net){if([netisHit]){continue;}CCARRAY_FOREACH([fishSheetchildren],fish){if([fishisCatch]){continue;}if(CGRectContainsPoint([netboundingBox],fish.position)){if(!([fishrandomCatch:cannonLevel])){continue;}else{fish.isCatch=YES;[selfupdateEnergy:fish.fishLevel];NSMutableArray*fishes=[NSMutableArrayarray];intnumber;if(fish.fishLevel<8){number=3;}else{number=5;}for(inti=1;i<number;i++){[fishesaddObject:[[CCSpriteFrameCachesharedSpriteFrameCache]spriteFrameByName:[NSStringstringWithFormat:@"fish0%i_catch_0%i.png",fish.fishLevel,i]]];}CCActionInterval*fish_catch_act=[CCRepeatactionWithAction:[CCAnimateactionWithAnimation:[CCAnimationanimationWithFrames:fishesdelay:0.2f]]times:2];CCSequence*animalSequence=[CCSequenceactions:fish_catch_act,[CCCallFuncOactionWithTarget:selfselector:@selector(afterCatch:)object:fish],n
