1つのチュートリアルからCocos2dの学習を始めたところです。「コウモリ」をランダムに飛ばしたいのですが、画面のどこかにタッチすると、すべてのコウモリがタッチ位置に集まり、再びランダムに飛んでいきます。
これが私のコードです:
-(id) init
{
if( (self=[super init])) {
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"Bat.plist"];
//Bats Array Initialization
bats = [[NSMutableArray alloc] init];
//Add bats using a batch node.
CCSpriteBatchNode *batch1 = [CCSpriteBatchNode batchNodeWithFile:@"Bat.png" capacity:10];
[self addChild:batch1 z:2 tag:TAG_BATS];
//Make them start flying up.
for(int x=0; x<5; x++){
//Create SimpleAnimObject of bat
bat1 = [SimpleAnimObj spriteWithBatchNode:batch1 rect:CGRectMake(0,0,48,48)];
[batch1 addChild:bat1];
[bat1 setPosition:ccp(arc4random()%900+40, arc4random()%600+50)];
[bat1 setScale:0.6f];
float flappingSpeed = [self makeBatFlyUp:bat1];
bat1.velocity = ccp((arc4random()%1000)/500 + 0.2f, 0.1f/flappingSpeed);
[bats addObject:[NSValue valueWithPointer:bat1]];
[bat1 retain];
//Set the bat's direction based on x velocity.
if(bat1.velocity.x > 0){
bat1.flipX = YES;
}
}
self.isTouchEnabled = YES;
[self schedule:@selector(step:)];
}
return self;
}
-(float)makeBatFlyUp:(SimpleAnimObj*)bat {
CCSpriteFrameCache * cache = [CCSpriteFrameCache sharedSpriteFrameCache];
float delay = (float)(arc4random()%5+5)/150;
CCAnimation *animation = [[CCAnimation alloc] initWithName:@"simply_bat_fly" delay:delay];
int num = arc4random()%9+1;
for(int i=1; i<=9; i+=1){
[animation addFrame:[cache spriteFrameByName:[NSString stringWithFormat:@"b%i.tiff",num]]];
num++;
if(num > 9){ num = 1; }
}
[bat stopAllActions];
[bat runAction:[CCRepeatForever actionWithAction: [CCAnimate actionWithAnimation:animation]]];
bat.animationType = BAT_FLYING_UP;
return delay;
}
タッチイベント:
-(BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event{
CGPoint touchLocation = [touch locationInView:[touch view]];
touchLocation = [[CCDirector sharedDirector] convertToGL:touchLocation];
touchLocation = [self convertToNodeSpace:touchLocation];
float velocityBat = 1024/3.0 ;
CGPoint moveDifference = ccpSub(touchLocation,bat1.position );
float distanceMove = ccpLength(moveDifference);
float moveduration = distanceMove / velocityBat;
// here i have to use Array but i don't know how to use array to access all same sprites.
self.moveAction = [CCSequence actions:
[CCMoveTo actionWithDuration:moveduration position:touchLocation],
[CCCallFunc actionWithTarget:self selector:@selector(bearMoveEnded)],
nil
];
[bat1 runAction:moveAction];
return YES;
}
コウモリはきちんと飛んでいますが、画面をタッチすると、タッチイベントに続くコウモリは1つだけで、他のコウモリはランダムに動き続けます。
誰かがここで私を助けることができますか?私が何かを逃したり、どこが間違っているのですか?
ありがとう!!
