Constrain CCRenderTexture to top of screen when using CCCamera - Cocos2d - iphone

i have a "mini map" that I am using to show a portion of the background.
How can I constrain the CCRenderTexure to the top right corner of the screen? I am also using CCCamera to follow a sprite.
in init()
CGSize s = [[CCDirector sharedDirector] winSize];
minimap = [[CCRenderTexture renderTextureWithWidth:s.width * 1.5 height:s.height * 1.5] retain];
[minimap setPosition:ccp( s.width - ( s.width * kMinimapScaleFactor ) - 5, s.height - ( s.height * kMinimapScaleFactor ) - 5)];
[minimap begin];
[self visit];
[minimap end];
CCSprite *mms = [minimap sprite];
[mms setScale:kMinimapScaleFactor];
mms.scaleY *= -1;
mms.anchorPoint = ccp(0, 0);
[self addChild:minimap z:1 tag:1];
[self schedule:#selector(updateMinimap:) interval:1.0f];
Above init()
#define kMinimapScaleFactor 0.2
-(void) updateMinimap: (ccTime) dt
{
[minimap begin];
[self visit];
[minimap end];
}
in .h
CCRenderTexture *minimap;
#property(nonatomic, retain) CCRenderTexture *minimap;
Here is how I use CCCamera
id cameraMove = [CCFollow actionWithTarget:_ball];
[self runAction:cameraMove];
Anyone know?
Thanks

All you have to do is add it to the scene id
+ (id)scene
{
CCScene *scene = [CCScene node];
GameScene *layer = [GameScene node];
[scene addChild:layer];
CGSize s = [[CCDirector sharedDirector] winSize];
layer.player = [CCRenderTexture renderTextureWithWidth:s.width height:s.height];
CCSprite *mms = [layer.player sprite];
[mms setScale:kMinimapScaleFactor];
mms.scaleY *= -1;
mms.position = ccp(300, 400);
[scene addChild:layer.player z:2 tag:1];
[layer schedule:#selector(updateMinimap:) interval:1/30.0f];
layer._mini = [CCSprite spriteWithFile:#"minimap.png"];
layer._mini.position = ccp(405, 255);
layer._mini.opacity = 150;
[scene addChild:layer._mini];
return scene;
}

Cocos2D - Layer background color not changing

I want to integrate cocos2d in one of my view. So, I have a normal view controller(MapEditorViewController) and a view, in my view controller, (I created a IBOutlet UIView *openGLView) in which I want cocos2d to be in. In my view controller, I have a method setupCocos2D :
- (void)setupCocos2D {
CCGLView *glView = [CCGLView viewWithFrame:self.openGLView.bounds
pixelFormat:kEAGLColorFormatRGB565 // kEAGLColorFormatRGBA8
depthFormat:0 // GL_DEPTH_COMPONENT16_OES
];
glView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
[self.openGLView insertSubview:glView atIndex:0];
[[CCDirector sharedDirector] setOpenGLView:glView];
CCScene *scene = [HelloWorldLayer scene];
[[CCDirector sharedDirector] runWithScene:scene];
}
setupCocos2D is called in viewDidLoad of the class MapEditorViewController.
I have a layer (HelloWorldLayer), which is basically the code in the tutorial of http://www.raywenderlich.com/25736/how-to-make-a-simple-iphone-game-with-cocos2d-2-x-tutorial
// Helper class method that creates a Scene with the HelloWorldLayer as the only child.
+(CCScene *) scene
{
// 'scene' is an autorelease object.
CCScene *scene = [CCScene node];
// 'layer' is an autorelease object.
HelloWorldLayer *layer = [HelloWorldLayer node];
// add layer as a child to scene
[scene addChild: layer];
// return the scene
return scene;
}
- (void) addMonster {
CCSprite * monster = [CCSprite spriteWithFile:#"backbutton.png"];
// Determine where to spawn the monster along the Y axis
CGSize winSize = [CCDirector sharedDirector].winSize;
int minY = monster.contentSize.height / 2;
int maxY = winSize.height - monster.contentSize.height/2;
int rangeY = maxY - minY;
int actualY = (arc4random() % rangeY) + minY;
// Create the monster slightly off-screen along the right edge,
// and along a random position along the Y axis as calculated above
monster.position = ccp(winSize.width + monster.contentSize.width/2, actualY);
[self addChild:monster];
// Determine speed of the monster
int minDuration = 2.0;
int maxDuration = 4.0;
int rangeDuration = maxDuration - minDuration;
int actualDuration = (arc4random() % rangeDuration) + minDuration;
// Create the actions
CCMoveTo * actionMove = [CCMoveTo actionWithDuration:actualDuration
position:ccp(-monster.contentSize.width/2, actualY)];
CCCallBlockN * actionMoveDone = [CCCallBlockN actionWithBlock:^(CCNode *node) {
[node removeFromParentAndCleanup:YES];
}];
[monster runAction:[CCSequence actions:actionMove, actionMoveDone, nil]];
}
// on "init" you need to initialize your instance
-(id) init
{
// always call "super" init
// Apple recommends to re-assign "self" with the "super's" return value
if( (self=[super initWithColor:ccc4(255,0,255,255)]) ) {
CGSize winSize = [CCDirector sharedDirector].winSize;
CCSprite *player = [CCSprite spriteWithFile:#"carteIntrouvable.png"];
player.position = ccp(player.contentSize.width/2, winSize.height/2);
[self addChild:player];
[self setIsTouchEnabled:YES];
[self schedule:#selector(gameLogic:) interval:1.0];
}
return self;
}
-(void)gameLogic:(ccTime)dt {
[self addMonster];
}
Now, I don't know what I'm doing wrong, the layer appears but it is black, even though I change the line initWithColor in -(id) init.
How can I change the layer's background color, because the code works if I don't integrate cocos2d with UIKit... ?
Alternative Solution: Add CCLayerColor to base layer.
-(void) onEnter
{
[super onEnter];
ccColor4B color = {255,255,0,255};
CCLayerColor *colorLayer = [CCLayerColor layerWithColor:color];
[self addChild:colorLayer z:LAST_LAYER_PLUS_1];
}

Adding a game over scene

I want to add this game over scene to this game that I am trying to do for my homework, and I seem to not have it where if you kill the target the game over scene will pop up. I tried putting my code in every line and see if it will finally work but no it didn't. So now I have to ask for some help.
. m file
- (void)addTarget10 {
Boss *target10 = nil;
if ((arc4random() % 2) == 0) {{
target10 = [WeakAndFastBoss9 boss9];
}} else {
target10 = [WeakAndFastBoss9 boss9];
}
[[SimpleAudioEngine sharedEngine] playEffect:#"lastboss.mp3"];
// Determine where to spawn the target along the Y axis
CGSize winSize = [[CCDirector sharedDirector] winSize];
int minY = target10.contentSize.height/2;
int maxY = winSize.height - target10.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
target10.position = ccp(winSize.width + (target10.contentSize.width/2), actualY);
[self addChild:target10 ];
// Determine speed of the target
int minDuration = target10.minMoveDuration;
int maxDuration = target10.maxMoveDuration;
int rangeDuration = maxDuration - minDuration;
int actualDuration = (arc4random() % rangeDuration) + minDuration;
// Create the actions
id actionMove = [CCMoveTo actionWithDuration:actualDuration position:ccp(- target10.contentSize.width/2, actualY)];
id actionMoveDone = [CCCallFuncN actionWithTarget:self
selector:#selector(spriteMoveFinished9:)];
[target10 runAction:[CCSequence actions:actionMove, actionMoveDone, nil]];
target10.tag = 1;
[_targets addObject:target10];
}
-(void)gameLogicboss9:(ccTime)dt {
[self unschedule:_cmd];
[self addTarget10];
}
- (void)updateboss9:(ccTime)dt {
CGRect projectileRect = CGRectMake(projectile.position.x - (projectile.contentSize.width/2),
projectile.position.y - (projectile.contentSize.height/2),
projectile.contentSize.width,
projectile.contentSize.height);
BOOL bossHit = FALSE;
NSMutableArray *targetsToDelete = [[NSMutableArray alloc] init];
for (CCSprite *target1 in _targets) {
CGRect target1Rect = CGRectMake(target1.position.x - (target1.contentSize.width/2),
target1.position.y - (target1.contentSize.height/2),
target1.contentSize.width,
target1.contentSize.height);
if (CGRectIntersectsRect(projectileRect, target1Rect)) {
[targetsToDelete addObject:target1];
bossHit = TRUE;
Boss *boss = (Boss *)target1;
boss.hp--;
if (boss.hp <= 0 ) {
[targetsToDelete addObject:target1];
}
break;
}
}
for (CCSprite *target in targetsToDelete) {
[_targets removeObject:target];
[self removeChild:target cleanup:YES];
_projectilesDestroyed++;
if (_projectilesDestroyed > 2) {
}
}
if (bossHit) {
//[projectilesToDelete addObject:projectile];
}
[targetsToDelete release];
}
-(void)spriteMoveFinishedboss9:(id)sender {
CCSprite *sprite = (CCSprite *)sender;
[self removeChild:sprite cleanup:YES];
if (sprite.tag == 1) { // target
[_targets removeObject:sprite];
} else if (sprite.tag == 2) { // projectile
[_projectiles removeObject:sprite];
} }
This the game over scene I want to add when target 10/ boss 9 is killed
GameOverScene *gameOverScene = [GameOverScene node];
[gameOverScene.layer.label setString:#"You Lose"];
[[CCDirector sharedDirector] replaceScene:gameOverScene];
Right now my other game over scene is when the sprite is moved passed screen.If you need me to answer any questions feel free to ask.
For scene replace you try this for your game code..
First Add this code to your GameOverScene class
+(CCScene *) scene
{
// 'scene' is an autorelease object.
CCScene *scene = [CCScene node];
// 'layer' is an autorelease object.
GameOverScene *layer = [GameOverScene node];
// add layer as a child to scene
[scene addChild: layer];
// return the scene
return scene;
}
Make your GameOverClass is subclass of CCLayer,
Than when You want to change scene do this
[[CCDirector sharedDirector] replaceScene:[GameOverScene scene]];
Ok, so you have to create a new scene. This can simple be done using File->New File and make it a subclass of NSObject. You then change the subclass to an CCLayer. As a test, you can just copy your code from the hello world layer. Next, just import the new class in your helloworld layer class and create a instance of it. Then in a method use [[CCDirector sharedDirector] replaceScene:sceneName];
You can use this site for more info, its very helpful, just read through it and you will find your answer:http://www.raywenderlich.com/352/how-to-make-a-simple-iphone-game-with-cocos2d-tutorial

Game play at multiple layers simultaneously in cocos2d

I am using 3 CCLayers in one Scene and I want simultaneous game play on all three layers, while user will play the game by switching between these layers. I can switch between these layers easily but my scheduled methods are not being called at all
Thats how I am doing it in the init() method of my scene and the line [self schedule:#selector(gameLogic:) interval:1.0]; is not working for me
Please help me where I am getting it wrong.
layer1 = [CCLayer node];
layer2 = [CCLayer node];
layer3 = [CCLayer node];
// add layer as a child to scene
[self addChild:layer1];
[self addChild:layer2];
[layer2 setVisible:NO];
[self addChild:layer3];
[layer3 setVisible:NO];
CCLabelTTF *layer1Label = [CCLabelTTF labelWithString:#"Layer1" fontName:#"Marker Felt" fontSize:64];
CGSize size = [[CCDirector sharedDirector] winSize];
layer1Label.position = ccp( size.width /2 , size.height/2 );
[layer1 addChild: layer1Label];
CCLabelTTF *layer2Label = [CCLabelTTF labelWithString:#"Layer2" fontName:#"Marker Felt" fontSize:64];
layer2Label.position = ccp( size.width /2 , size.height/2 );
[layer2 addChild: layer2Label];
CCLabelTTF *layer3Label = [CCLabelTTF labelWithString:#"Layer3" fontName:#"Marker Felt" fontSize:64];
layer3Label.position = ccp( size.width /2 , size.height/2 );
[layer3 addChild: layer3Label];
[self schedule:#selector(gameLogic:) interval:1.0];
}
return self;
}
Ohh dear I got it set myself. The problem was nowhere in init(). [super onEnter] was missing in -(void)onEnter method. Now all my scheduled methods are doing fine.

cocos2d: How do I Control a scrolling map

I made my map to scroll automatically however I would like to know how can I slow down the scrolling before the map reaches the end and when it does I would like the map to stop scrolling. I want to know how to do this because my game is about the player trying to shoot the enemy before he reaches the end of the map where there is shelter for him to hide. I would like that before the enemy reaches the shelter have the scrolling slow down and when the enemy reaches the shelter I would like the map to stop scrolling.
Here is the code:

cocos2d problem - layer not updating quick enough

i am adding overlays to a cocos2d layer in preparation for a screenshot...
CGSize winSize = [[CCDirector sharedDirector] winSize];
CCScene* currentScene = [[CCDirector sharedDirector] runningScene];
GameLayer* topLayer = (GameLayer *)[currentScene.children objectAtIndex:0];
CCSprite *middleBackground = [CCSprite spriteWithFile:#"mid_bg.png"];
middleBackground.position = ccp(winSize.width * 0.5,winSize.height * 0.55);
[topLayer addChild:middleBackground z:3 tag:111];
CCSprite *bottomBackground = [CCSprite spriteWithFile:#"bot_bg.png"];
bottomBackground.position = ccp(winSize.width * 0.5,winSize.height * 0.1);
[topLayer addChild:bottomBackground z:3 tag:112];
CCSprite *topBackground = [CCSprite spriteWithFile:#"top_bg.png"];
topBackground.position = ccp(winSize.width * 0.5,winSize.height * 0.94);
[topLayer addChild:topBackground z:3 tag:113];
[[UIApplication sharedApplication] setStatusBarHidden:YES];
CCSprite *topBackground2 = [CCSprite spriteWithFile:#"statusCover2.png"];
topBackground2.position = ccp(winSize.width * 0.5,winSize.height * 0.992);
[topLayer addChild:topBackground2 z:3 tag:114];
[[topLayer popoverController] dismissPopoverAnimated:YES];
then
[UIImage imageWithCGImage:UIGetScreenImage()];
However the later is not taking the overlays into account. It is taking a screenshot of the layer before the overlays are added.
Is there anyway I can tell the cocos2d scene/layer to update the frame NOW?
Because cocos2d is asynchronous you can't tell it to do something like that. However, you can schedule a callback to happen in two seconds and have that callback do the screen capture.
[self schedule: #selector(screenshot:) interval:2.0];
then define the selector like this:
-(void) screenshot:(id)sender {
[UIImage imageWithCGImage:UIGetScreenImage()];
[self unschedule:#selector(screenshot:)];
}
don't forgot to unschedule it.
