SO i'm creating a object called Enemy from the main game class
the enemy object is calling ccrepeatforever on a ccmoveto
i retained the move and repeat but still getting crashes
here is some code
for (Enemy *iceLord in self.children) {
if ([iceLord isKindOfClass:[Enemy class]] && iceLord.isIceLord==YES) { <-----this is where EXC_BAD_ACCESS is showing up
//DO Stuff
}
}
//inside of the enemyClass i have this method i think this is causing the crash but i can not see why
-(void)startWiggle{
int randomX = (arc4random()%30)+15;
int randomY = (arc4random()%40)+15;
int dieroll = arc4random()%2+1;
if (dieroll==1) {
randomY=randomY* -1;
}
if (self.position.y < winSize.height && self.position.y >0) {
id move = [CCMoveBy actionWithDuration:1 position:CGPointMake(-randomX, randomY)];
id forever = [CCRepeatForever actionWithAction:move];
[self runAction:forever];
[move retain];
[forever retain];
}

The following code I'm using is to end the game when I my number of balls in the scene reaches zero. Now I'm not getting any error when I put the code in but it doesn't do any thing as of counting the balls and reacting to that count. I am fairly new to sprite kit so I understand that this is a problem that comes so easy to others but this is the first time of worked with reacting to the count of a certain sprite in a scene so please help.
SKSpriteNode *ball;
int numberOfBalls = 3;
#implementation EasyScene
-(void)didBeginContact:(SKPhysicsContact *)contact {
if ([self isGameWon]) {
EasyEndGameScene *end = [EasyEndGameScene sceneWithSize:self.size];
[self.view presentScene:end transition:[SKTransition doorsCloseHorizontalWithDuration:1]];
}
}
-(BOOL)isGameWon {
int numberOfBalls = 3;
for (SKNode* node in self.children) {
if ([node.name isEqual: ball]) {
numberOfBalls = 0;
}
}
return numberOfBalls =0;
}
- (void) addBalls:(CGSize)size {
for (int i = 0; i < 3; i++) {
//create brick sprite from image
SKSpriteNode *ball = [SKSpriteNode spriteNodeWithImageNamed:#"ball-image"];
ball.name = #"ball";
//resize balls
ball.size = CGSizeMake(self.size.width/5.5, self.size.width/5.5);
//position and space out balls
int xPos = size.width/3 * (i+.5);
int yPos = self.size.height - (self.size.width/7);
ball.position = CGPointMake(xPos, yPos);
ball.physicsBody = [SKPhysicsBody bodyWithCircleOfRadius:ball.size.width/2];
ball.physicsBody.categoryBitMask = ballCategory;
ball.physicsBody.contactTestBitMask = bottomEdgeCategory;
[self addChild:ball];
}
}
In the following code I got rid of the Global Variable and tested all nodes for the specified name of #"ball" and return YES if none were found:
static const uint32_t ballCategory = 1; //00000000000000000000000000000001
static const uint32_t edgeCategory = 2; //00000000000000000000000000000010
static const uint32_t bottomEdgeCategory = 4; //00000000000000000000000000000100
SKSpriteNode *ball;
#implementation EasyScene
-(void)didBeginContact:(SKPhysicsContact *)contact {
//create placeholder for the "non ball" object
SKPhysicsBody *notTheBall;
SKPhysicsBody *theBall;
if (contact.bodyA.categoryBitMask < contact.bodyB.categoryBitMask) {
notTheBall = contact.bodyB;
theBall = contact.bodyA;
} else {
notTheBall = contact.bodyA;
theBall = contact.bodyB;
}
if (notTheBall.categoryBitMask == bottomEdgeCategory) {
NSLog(#"hit bottom edge");
// SKAction *playSFX = [SKAction playSoundFileNamed:#"gameover.mp3" waitForCompletion:NO];

// [GameState sharedInstance].score = 0;
// [gameMusic pause];
[theBall.node removeFromParent];
}
if ([self isGameWon]) {
EasyEndGameScene *end = [EasyEndGameScene sceneWithSize:self.size];
[self.view presentScene:end transition:[SKTransition doorsCloseHorizontalWithDuration:1]];
}
}
-(BOOL)isGameWon {
unsigned count = 0;
for (SKNode* node in self.children)
if ([node.name isEqual:ball])
count++;
return count == 0;
}
- (void) addBalls:(CGSize)size {
for (int i = 0; i < 3; i++) {
//create brick sprite from image
SKSpriteNode *ball = [SKSpriteNode spriteNodeWithImageNamed:#"ball-image"];
ball.name = #"ball";
//resize balls
ball.size = CGSizeMake(self.size.width/5.5, self.size.width/5.5);
//position and space out balls
int xPos = size.width/3 * (i+.5);
int yPos = self.size.height - (self.size.width/7);
ball.position = CGPointMake(xPos, yPos);
ball.physicsBody = [SKPhysicsBody bodyWithCircleOfRadius:ball.size.width/2];
ball.physicsBody.categoryBitMask = ballCategory;
ball.physicsBody.contactTestBitMask = bottomEdgeCategory;
[self addChild:ball];
}
}
Remove the ball global variable, as it's not needed.
Test all nodes for the specified name of #"ball" and return YES if none were found:
-(BOOL)isGameWon {
for (SKNode* node in self.children)
if ([node.name isEqualToString:#"ball"])
return NO;
return YES;
}
I think it should be
return numberOfBalls == 0
in your isgameWon method
you forget an extra =
I have my background set and it is scrolling horizontally, here is my code:
-(void)initalizingScrollingBackground
{
for (int i = 0; i < 2; i++)
{
SKSpriteNode *bg = [SKSpriteNode spriteNodeWithImageNamed:#"background"];
bottomScrollerHeight = bg.size.height;
bg.position = CGPointMake(i * bg.size.width, 0);
bg.anchorPoint = CGPointZero;
bg.name = #"background";
[self addChild:bg];
}
}
and also this code:
- (void)moveBottomScroller
{
[self enumerateChildNodesWithName:#"background" usingBlock: ^(SKNode *node, BOOL *stop)
{
SKSpriteNode * bg = (SKSpriteNode *) node;
CGPoint bgVelocity = CGPointMake(-BG_VELOCITY, 0);
CGPoint amtToMove = CGPointMultiplyScalar(bgVelocity,_dt);
bg.position = CGPointAdd(bg.position, amtToMove);
//Checks if bg node is completely scrolled off the screen, if yes then put it at the end of the other node
if (bg.position.x <= -bg.size.width)
{
bg.position = CGPointMake(bg.position.x + bg.size.width*2,
bg.position.y);
}
[bg removeFromParent];
[self addChild:bg]; //Ordering is not possible. so this is a hack
}];
}
The second part makes the background scroll. Without it, the background is still.
Also, without the movebottomscroller, my sprite appears on top of the background. With the movebottomscroller, he appears behind the scrolling background. Is there any command to bring him to the front, above any other backgrounds?
Thank you!
Try the approach below, hope that works for you.

I don't fully understand your approach here, but I can answer your question so I'll just go ahead and do that - I hope I haven't misunderstood.
SKNode has a method insertChild:atIndex: that would allow you to put the background nodes at the back, or put the sprite at the front.

I am trying to change a SKSpriteNode's texture while it is animated , but I faced with FPS dropping ! it goes down from 60 to 30 ! on both device and simulator ! the node is a parallel scrolling background , and here is the codes :
- (void)createBricksEdge {
brickEdges = [[SKSpriteNode alloc]initWithImageNamed:#"edge.png"];
brickEdges.position = CGPointMake(CGRectGetMidX(self.frame), CGRectGetMidY(self.frame));;
brickEdges.name = #"edge";
[self addChild:brickEdges];
bEdge1 = [[SKSpriteNode alloc]initWithImageNamed:#"edge.png"];
bEdge1.position = CGPointMake(brickEdges.position.x,brickEdges.position.y+(brickEdges.size.height));
bEdge1.name = #"edge";
[self addChild:bEdge1];
}
moving background :
- (void)moveBg
{
[self enumerateChildNodesWithName:#"edge" usingBlock: ^(SKNode *node, BOOL *stop)
{
SKSpriteNode * bg = (SKSpriteNode *) node;
if (isSpeedBonus == YES) {
SPEED = 200;
} else {
switch (speedCriteria) {
case 0:
SPEED = 7.0;
break;
case 1:
SPEED = 11;
NSLog(#"FPS drops");
[bg runAction:[SKAction setTexture:[SKTexture textureWithImage:[UIImage imageNamed:#"edgeSpeed.png"]]]];
//I also tried : [bg setTexture:textre];
break;
.
.
.
.
.
}
}
bg.position = CGPointMake(bg.position.x , bg.position.y - SPEED);
if (bg.position.y <= -bg.size.width)
{ bg.position = CGPointMake(bg.position.x ,bg.position.y + bg.size.height*2); }} ];
}
Updating frames :
- (void)speedOMeter
{
int i = (int)[scoreLabel.text integerValue];
if (i <= 1000) {
speedCriteria = 0;
} else if (i <= 1500) {
speedCriteria = 1;
} else if (i <=2000) {
speedCriteria = 2;
} else if (i <= 2500) {
.
.
.
.
}
- (void)update:(CFTimeInterval)currentTime {
if (_lastUpdateTime)
{
_dt = currentTime - _lastUpdateTime;
}
else
{
_dt = 0;
}
_lastUpdateTime = currentTime;
[self moveBg]; [self speedOMeter];
}
You're bypassing the Sprite Kit caching mechanisms by creating the image first as a UIImage. This will load the image from disk, possibly every time:
[bg runAction:[SKAction setTexture:[SKTexture textureWithImage:[UIImage imageNamed:#"edgeSpeed.png"]]]];
Besides that you're overdoing it with the action. Try again with the simplified version that'll give you the same result by simply assigning the texture:
bg.texture = [SKTexture textureWithImageNamed:#"edgeSpeed.png"];

My problem is with the -(void)removeSprite:(CCSprite *)sprite{method. This is supposed to delete only the one it got called with, but instead it kills them all, as you can see in this log.

15:14:11.821 Tile[1549:c07] elseCO cbc: 0
15:14:11.821 Tile[1549:c07] StopCheckDamage
If you look at the log location in the code above, you will see that it deletes two instead of the one I wanted to. How can I prevent this behaviour or customise it to only kill the proper sprite?
Edit: To clarify
I thought that as I use the spritein the -(void)explosionFromPoint:(CGPoint)explosionPoint withSprite:(CCSprite*)sprite; this would somehow just give an unique ID to the object and know which one I was talking about. I'm new to coding.
You have the same sprite in the array twice. Both entries are removed. If you're going to use removeObject you need to create multiple sprite objects. Otherwise you need to use removeObjectAtIndex.
The problem as #HotLicks mentioned is you push the same instance in the array.
You should use a local CCSprite instance so your scheduled calls will use different instances. The reason for adding the same instance twice is because placeBomb is called twice before anything happens and in the second call you override the first instance you created. Since _circle is a pointer by the time both scheduled tasks will be called _circle will point to the same instance in both.
So change :
_circle = [[CCSprite alloc]initWithFile:#"Circle.png"];
To :
CCSprite *circle = [[CCSprite alloc]initWithFile:#"Circle.png"];
and update the rest of the method with circle and not _circle.
There is something that is going wrong in your code. Try checking something like that when you remove object from array do this:
if([currentBombs count]>1 )
[currentBombs removeObjectAtIndex:1];
If your code works fine. that is only one object removed from your array. Then I suggest you to check your removeSprite method print sprite object to check what's going wrong.
I think you can use tag values if you using same sprite objects.
You probably added the same (indiviudal) sprite twice?
Instead of logging a variable that has the count, you can log the object itself. It will print the value of its description. That will print out the class and address for all NSObject subclasses per default. Actually NSMutableArray (and similar NS... classes) print quite well.
NSLog ("%#",myObj);
Doing so you probably see more clearly what really happens.
Don't use class variable while creating bombs and try....

float length = sqrtf((offRealX*offRealX) + (offRealY*offRealY));
float velocity = 480/1; // 480pixels/1sec
float realMoveDuration = length/velocity;
// Move projectile to actual endpoint
id actionMoveDone = [CCCallFuncN actionWithTarget:self
selector:#selector(projectileMoveFinished:)];
[projectile runAction:
[CCSequence actionOne:
[CCMoveTo actionWithDuration: realMoveDuration
position: realDest]
two: actionMoveDone]];
[self.projectiles addObject:projectile];
}
}
The problem is that only the projectileButtonTapped: in the HudLayer is called (ie. the delegate's method never gets called).
P.S.
To save space I left out both .h files. But I assure you they are correct, with the #protocol used in HudLayer and that same protocol name put in <> within the HelloWorldLayer.
I think :
- (void)projectileButtonTapped:(id)sender
{
NSLog(#"projectileButtonTapped HudLayer");
if ([self.delegate respondsToSelector:#selector(projectileButtonTapped:)]) {
[self.delegate performSelector:#selector(projectileButtonTapped:) withObject:sender];
}
}
