I'm using Cocos2D 0.99.5. I have a CCParallaxNode with background sprites added to it. For some reason, none of them display until I start my map starts moving around a bit. The scroll slowly with the players movement.
I have this added to init:
winSize = [CCDirector sharedDirector].winSize;
bgMountainsMax = floor(winSize.width/240)+1;
if((int)winSize.width%240 > 0){
bgMountainsBumper = ((int)winSize.width%240)/bgMountainsMax;
}else{
bgMountainsBumper = 0;
}
backgroundNode = [CCParallaxNode node];
[self addChild:backgroundNode z:-1];
CGPoint mountainSpeed = ccp(0.5, 0.5);
bgMountains = [[NSMutableArray alloc] initWithCapacity: bgMountainsMax];
for(int i=0; i<bgMountainsMax; ++i){
mountain = [CCSprite spriteWithFile:#"mountainBG1.png"];
mountain.opacity = 80;
[bgMountains insertObject:mountain atIndex:i];
[backgroundNode addChild:[bgMountains objectAtIndex:i] z:0 parallaxRatio:mountainSpeed positionOffset:ccp((240*i)+(bgMountainsBumper*i),98)];
}
And this added to update:
for (CCSprite *mountainNum in bgMountains) {
if ([backgroundNode convertToWorldSpace:mountainNum.position].x < -(240/2)) {
[backgroundNode incrementOffset:ccp(winSize.width+(240),0) forChild:mountainNum];
}
if ([backgroundNode convertToWorldSpace:mountainNum.position].x > winSize.width+(240/2)) {
[backgroundNode incrementOffset:ccp(-(winSize.width+240),0) forChild:mountainNum];
}
}
I think you should be calling the update function stuff once at the end of your init stuff
[backgroundNode incrementOffset:ccp(winSize.width+(240),0) forChild:mountainNum];
[backgroundNode incrementOffset:ccp(-(winSize.width+240),0) forChild:mountainNum];
without the conditionals, to set it up initially.

Here some code for Add sprite for Enemies.....
_robbers = [[CCArray alloc] initWithCapacity:kNumAstroids];
for (int i = 0; i < kNumAstroids; ++i) {
CCSprite *asteroid = [CCSprite spriteWithSpriteFrameName:#"robber.png"];
asteroid.visible = NO;
[_batchNode addChild:asteroid];
[_robbers addObject:asteroid];
}
And in Update method ........
double curTime = CACurrentMediaTime();
if (curTime > _nextRunemanSpawn) {
float randSecs = [self randomValueBetween:0.20 andValue:1.0];
_nextRunemanSpawn = randSecs + curTime;
float randY = [self randomValueBetween:80 andValue:80];
float randDuration = [self randomValueBetween:4.5 andValue:4.5];
float randDuration1 = [self randomValueBetween:1.0 andValue:1.0];
CCSprite *asteroid = [_robbers objectAtIndex:_nextRobber];
_nextRobber++;
if (_nextRobber >= _robbers.count) {
_nextRobber = 1;
}
[asteroid stopAllActions];
asteroid.position = ccp(winSize.width +asteroid.contentSize.width / 2 , randY);
asteroid.visible = YES;
[asteroid runAction:[CCSequence actions:[CCMoveBy actionWithDuration:randDuration position:ccp(-winSize.width-asteroid.contentSize.width, 0)],
[CCCallFuncN actionWithTarget:self selector:#selector(setInvisible:)],nil]];
All Sprites are Move from right to left in screen
when Sprite crosses the middle of the screen it automatically disappear
what is the reason for this problem ??
I agree with the previously mentioned statement from LearnCocos2D. It is also possible that you are adding multiple objects and reaching the end of the capacity in the line
_robbers = [[CCArray alloc] initWithCapacity:kNumAstroids];
If you try to spawn more objects than whatever number you have specified for kNumAsteroids it will remove the oldest object and use the new one in its place. I.e. if kNumAsteroids is 5, you have 5 on the screen and then add a sixth, 1 will become 6 and its position will be whatever you set it to.
i have this code to show animation of a image
-(void) blink:(ccTime) delta {
animateblink ++; //adds 1 every frame
if (animateblink <= 6 ) { //if we included frames to show for breaking and the current frame is less than the max number of frames to play
if (animateblink < 6) {
[sprite setTexture:[[CCSprite spriteWithFile:[NSString stringWithFormat:#"%#_blinkk00%i.png", baseImageName,animateblink]] texture]];
[self unschedule:_cmd];
[self schedule:#selector(openEyes:) interval:0.1f];
[self schedule:#selector(moveSprite:) interval:0.1f];
}
}
}
i have 6 images of animating like
dragonimage_blinkk001,dragonimage_blinkk002,dragonimage_blinkk003,dragonimage_blinkk004,dragonimage_blinkk005,dragonimage_blinkk006 like that
i put two methods,
1: for animation time
2: for movement of the image
the code is
-(void) openEyes:(ccTime) delta {
[sprite setTexture:[[CCSprite spriteWithFile:[NSString stringWithFormat:#"%#.png", baseImageName]] texture]];
[self unschedule:_cmd];
int blinkInterval = (arc4random() % 6) + 1; // range 3 to 8
[self schedule:#selector(blink:) interval:blinkInterval];
}
-(void)moveSprite:(ccTime)delta
{
movementCounter ++;
if (movementCounter == 1000) {
[self unschedule:_cmd];
}
else
{
spriteimagename.position = ccp(spriteimagename.position.x+10,spriteimagename.position.y);
}
}
but on the first method the animation time is not correct,there is a lot of delay of animation,i just want to show animation of the images randomly and fast,its a dragon flying animation.
my sec on method is not at all working,i didn't get any movement of that image.
i hope you understand my issue.how to solve the above two method issues.
Thanks in advance.
Quick solution is to add frameIndex member in cocos2d CCSpriteFrame class. i don't know is that allowed to change. But it works fine.
#interface CCSpriteFrame : NSObject <NSCopying>
{
int frameIndex;
....
}
//Here in code initialize frames with unique index
CCAnimation* animation;
NSMutableArray *animFrames2 = [NSMutableArray array];
for( int i=1;i<=15;i++)
{
CCSpriteFrame *frame = [cache spriteFrameByName:[NSString stringWithFormat:#"ActerSmash_%d.png",i]];
frame.frameIndex = (int)i;
[animFrames2 addObject:frame];
}
animation = [CCAnimation animationWithFrames:animFrames2];
CCAnimate *action = [CCAnimate actionWithDuration:ACTER_SMASH_SPEED animation:animation restoreOriginalFrame:YES];
action.tag = kTagAnimationSmashAnim ;
mActer.AnimSmash = action;
//Checking frame Index
CCAnimate *anim = mActer.AnimSmash ;
for(CCSpriteFrame *frame in anim.animation.frames)
{
if([mActer isFrameDisplayed:frame] ) )
{
if(frame.frameIndex == 5 )
{
//Do something..
}
}
}
I want a snow particle effect to follow my sprite and I tried some methods but all that ends up happening is the snow will just stay still instead of following. I did this one tutorial (will post as soon as I find it) thats shows how it do it with fire but didn't work out at all. Any tutorials or suggestions will be appreciated. I believe i have to add some kind of code to the snippet part where it says create enemy off screen.

int minY = target1.contentSize.height/2;
int maxY = winSize.height - target1.contentSize.height/2;
int rangeY = maxY - minY;
int actualY = (arc4random() % rangeY) + minY;
// Create the target slightly off-screen along the right edge,
// and along a random position along the Y axis as calculated above
target1.position = ccp(winSize.width + (target1.contentSize.width/2), actualY);
[self addChild:target1 ];
// Determine speed of the target

I Have found this, at CCParticleSystem.h
/** #typedef tCCPositionType
possible types of particle positions
/
typedef enum {
/* Living particles are attached to the world and are unaffected by emitter repositioning. */
kCCPositionTypeFree,
/** Living particles are attached to the world but will follow the emitter repositioning.
Use case: Attach an emitter to an sprite, and you want that the emitter follows the sprite.
*/
kCCPositionTypeRelative,
/** Living particles are attached to the emitter and are translated along with it. */
kCCPositionTypeGrouped,
you should set it like
myparticleSystem.positionType=kCCPositionTypeGrouped;
Hope it helps.
You don't need to update the particle emitter's position with the sprite.
You can add a particle system to the sprite as a child.
The particle system does need to be typed as such:
CCParticleSystem * booster = [CCParticleSystem particleWithFile:#"boosterParticles.plist"];
//customize your particles' options
//assuming you have a sprite defined as _motherShip
[_motherShip addChild:booster];
/*
* now that the particles are the _motherShip's child, you must remember
* to set the position relative to the mothership's origin...
*/
particles.position = ccp(15,0);
...So now whenever _motherShip.position changes, the booster will follow. It will even rotate with the ship.
Very simple logic without getting into code:
I spawn a sprite and give it a location (x, y).
For each sprite, I also spawn a CCParticleSystem, give it the required particle type, spawn rates etc.
The CCParticleSystem location is now set to be the same (x,y) location as the sprite, and it should get updated as the sprite's (x,y) location is update.
As the sprite and the CCParticleSystem move around, this location (x, y) is getting updates constantly at random in your schedule method per the interval step time.
Hope that makes sense.
I do this
vehicleParticleSystem = [CCParticleSystemQuad particleWithFile:#"vehicleParticle.plist"];
vehicleParticleSystem.position = ccp(_ship.position.x - _ship.contentSize.width/3, _ship.position.y - _ship.contentSize.height/3);
if (UI_USER_INTERFACE_IDIOM() != UIUserInterfaceIdiomPad) {
vehicleParticleSystem.scale = 0.5;
}
[self addChild:vehicleParticleSystem z:-1];
and update its position with this
- (void) updateParticleSystem:(ccTime)dt {
vehicleParticleSystem.position = ccp(_ship.position.x - _ship.contentSize.width/3, _ship.position.y - _ship.contentSize.height/3);
}
which is called in the -(void) update:(ccTime)dt method.
The ship is moved by the user via a joypad.
hope this helps. The positioning for the particle is slightly behind the vehicle for an engine effect.
Did you tried to update your particle position taking advantage of the update method?
I'm doing something like the following lines in one of my games and it works as I think you expect
-(void) update:(CCTime)delta{
_sprite.position = CGPointMake(newXPosition, newYPosition);
_fire.position = CGPointMake(_sprite.position.x, _sprite.position.y);
}
I hope it helps!
Let me explain it in depth, when ever if(CGRectContainsPoint([hole1 boundingBox], ball1.position)) condition goes true, i do lots of stuffs, like unscheduled, a selector, destroying a ball body calling an animation (please refer Code below)etc. This work properly most of the time. But sometimes when ball is really near to hole(just touching the hole but but not enough to make the above condition true), or is been throws towards the hole really fast speed, then application got terminated. I have checked, by commenting many actions which are been performed in this section, but got nothing helpful, application keep terminating when some efforts are been done to make it terminate.
if(CGRectContainsPoint([hole1 boundingBox], ball1.position))
{
ballBody->SetLinearVelocity(b2Vec2(0.0f,0.0f));
ballBody->SetAngularVelocity(0.0f);
[self unschedule:#selector(tick:)];
self.isTouchEnabled = NO;
[self removeChild:ball1 cleanup:YES];
world->DestroyBody(ballBody);
// create the sprite sheet
CCSpriteSheet *spriteSheet;
GolfBallsAppDelegate *appDelegate = (GolfBallsAppDelegate *)[[UIApplication sharedApplication] delegate];
if([appDelegate.ballValue isEqualToString:#"cricketball"])
{
spriteSheet = [CCSpriteSheet spriteSheetWithFile:#"cricket_ball_strip.png"];
}
else if([appDelegate.ballValue isEqualToString:#"ironball"])
{
spriteSheet = [CCSpriteSheet spriteSheetWithFile:#"iron_ball_strip.png"];
}

spriteSheet = [CCSpriteSheet spriteSheetWithFile:#"golf_ball_strip.png"];
}

}
else if([appDelegate.ballValue isEqualToString:#"basketball"])
{
spriteSheet = [CCSpriteSheet spriteSheetWithFile:#"basket_ball_strip.png"];
}
spriteSheet.position = ccp(hole1.position.x,60);
[self addChild:spriteSheet];
float frameWidth = 96;
float frameHeight = 84;
CCSprite *sprite = [CCSprite spriteWithTexture:spriteSheet.texture rect:CGRectMake(0, 0, frameWidth, frameHeight)];
[spriteSheet addChild:sprite];
//if(animation)
{
// create the animation
CCAnimation *spriteAnimation = [CCAnimation animationWithName:#"potting" delay:0.1f];
int frameCount = 0;
for (int x = 0; x < 6; x++)
{
// create an animation frame
CCSpriteFrame *frame = [CCSpriteFrame frameWithTexture:spriteSheet.texture rect:CGRectMake(x*frameWidth,0*frameHeight,frameWidth,frameHeight) offset:ccp(0,0)];
[spriteAnimation addFrame:frame];
frameCount++;
// stop looping after we've added 14 frames
if (frameCount == 6)
{
//[self removeChild:spriteSheet cleanup:YES];
break;
}
}
// create the action
CCAnimate *spriteAction = [CCAnimate actionWithAnimation:spriteAnimation];
//CCRepeatForever *repeat = [CCRepeatForever actionWithAction:spriteAction];
// run the action
[sprite runAction:spriteAction];
//[sprite runAction:repeat];
}
[self schedule:#selector(loading) interval:0.5];
[self schedule:#selector(holeFinish) interval:1];
//[self removeChild:spriteSheet cleanup:YES];
}
Any suggestion will be highly appreciated.
EDIT: What i found is, problem with folling lines [self removeChild:ball1 cleanup:YES];
world->DestroyBody(ballBody);
(MAY be). but as it not occurs always, (as I mentioned), thus it's being ridiculous.
I think your problem will be that you are trying to delete a body when the b2World is 'locked', (When the world is busy working out collisions).
Try flagging the object as ready for deletion, and deleting it at the start of your next loop:
Replace:
[self removeChild:ball1 cleanup:YES];
world->DestroyBody(ballBody);
with
ball1.isDead = YES;
And at the start of your next game loop:
for (Ball b in balls)
{
if (b.isDead)
world->DestroyBody(b.ballBody);
}
I have added some sprite by using the following code and then by checking the rect
intersection I want to replace these sprites with another one.Can you help me out by providing code
to replace these random images.Problem is that the image to be replaced is also taken
randomly.........
yp = 40;
//CCSprite *spr;
movableSprites = [[NSMutableArray alloc] init];

//NSLog(#"valueeeeeeeeenexttttt %d",next);
i+=next;

I have did this using sprite sheet. if you can create a sprite sheet and then assign that sprite sheet to CCSpriteBatchNode's object like
$ CCSpriteBatchNod * m_meteoritesSprites =[CCSpriteBatchNode batchNodeWithFile:#"Meteo.pvr.ccz"];
and then load plist
$[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:#"Meteo.plist"];
and then use sprite frames to assign images to your sprite like
$ m_meteoritesSprites =[CCSpriteBatchNode batchNodeWithFile:#"Meteo.pvr.ccz"];
i used TexrturePacker to make sprite sheets
hope this helps you.
