Cocos2d-android - I have an animation which has 5 Frames. which will rolling in position. how to make the button rolling like a globe.
I don't know if it can be done like menuitem, but you can make a sprite with forever action(animation of yours 5 frames)and in ccTouchesBegan/ccTouchesEnded you add code to go to another scene or for do an another function after touching on your sprite.
`private CCSprite animatedButton; // Make your sprite visible at begin of your class/layer.`
`animatedButton = CCSprite.sprite("yourImage.png");
CCAnimation buttonAnimation = CCAnimation.animation("", 1f);
buttonAnimation.addFrame("1.png");
buttonAnimation.addFrame("2.png");
addChild(animatedButton, 1);
CCIntervalAction buttonAction = CCAnimate.action(duration, buttonAnimation, false);
animatedButton.runAction(CCRepeatForever.action(buttonAction));
`
Now should be your button(CCSprite) animating. I didnt tried code. And now you just find out in ccTouchesBegan or ccTouchesEnded if your button was touched. If yes, you could do what you want. :)
`if(animatedButton.getBoundingBox.contains(x,y)){
CCScene scene = GameLayer.scene();
CCDirector.sharedDirector().replaceScene(scene);
}`
X and y are coordinates of touch;
You can add animations to menuitem. Like this
CCMenuItem button=CCMenuItemImage.item(image, image, this, "label");
button.setScaleX((winSize.width/8.0f)/image.getTexture().getWidth());
button.setScaleY((winSize.height/8.0f)/image.getTexture().getHeight());
button.setPosition(winSize.width/2,winSize.height+50);
CCAction actionMove42=CCSequence.actions(CCDelayTime.action(0.3f), CCEaseBackOut.action(CCMoveTo.action(1.0f, CGPoint.ccp(0,0))));
button.runAction(actionMove42);

I know how to detect contact on all of my sprites that on screen .
I also know how to run animation forever on a sprite .
But when puting together the code for animation, with sprite sheet- you dont actually add the sprite as a child, but ONLY the sprite-sheet, than the sprite is a child of the sprite-sheet.
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:#"parrot.plist"];
CCSpriteBatchNode *spriteSheet = [ CCSpriteBatchNode batchNodeWithFile:#"parrot.png"];
fireBall=[CCSprite spriteWithSpriteFrameName:#"parrot1.png"];
fireBall.position=point;
[spriteSheet addChild:fireBall];
[self addChild:spriteSheet];
//here animation action perform on fireBall
In that case when looking for the fireBall for contact detection - you cant find him because he is not added as a child of the scene ,but of the sprite sheet.
How can i detect that sprite later on my code ? or there is another constellation to set the sprite sheet ?
thanks
You can get your fireBall sprite normally, like any other sprite...
There's some ways:
1) Create a property for your fireBall sprite:
#property (nonatomic, retain) CCSprite *fireBall;
And create and use it using self.fireball:
self.fireBall=[CCSprite spriteWithSpriteFrameName:#"parrot1.png"];
...
CGPoint fireBallPosition = self.fireBall.position;
2) Add fireBall as child on spriteSheet using tag, and get it back using the same tag.
[spriteSheet addChild:fireBall z:0 tag:1];
...
theFireBall = [spriteSheet getChildByTag:1];
But keep in mind that the fireBall position is relative of their parent, spriteSheet. So, if you move spriteSheet, you will also move spriteSheet.
-(void) redafter1
{
red = [CCMenuItemImage
itemFromNormalImage:#"red.png" selectedImage:#"redclick.png"];
red.position = ccp(175, 725);
redMenu = [CCMenu menuWithItems:red, nil];
redMenu.position = CGPointZero;
redMenu.scale = .75;
[self addChild:redMenu z:10];
}
How would I go about animating this object to move to another location on the screen? I am very new to this, please be basic in your explanation.
If you want to animate CCNode (this is base class of all cocos2d objects such as layers, sprites, labels, menuitems, etc.), you have to use actions mechanism. To move object, use CCMoveTo, CCMoveBy actions with runAction: method.
id moveAction = [CCMoveTo actionWithDuration: animationDuration position: targetPosition];
[nodeToAnimate runAction: moveAction];
In your case if you will run action on the object right after adding it to the some parent, that is visible (your scene or other visible parent), action will be started right after object appear.
You add [redMenu runAction:[CCMoveTo actionWithDuration:time position:place]]; (you choose time and position) at the end of your redafter1 function so when the parent method is eventually called by a method such as init your menu will move.Remember you cannot move a CCMenuItemImage because it's locked to the CCMenu's position. You have to move the CCMenu itself.Hope this was helpful.
i'm newbie to both cocos2d and box2d and i've been struggling for two days with this problem : i have a scene with many sprites dropping down (with bodies attached to them). and i have a BackgroundLayer from which i add my background image into the scene (which is not involded into the physics simulation). In my backgroundLayer i'm trying to perform an action on a sprite :
(it blink in the first position and jump directly to the end position )
id flyBubble = [CCEaseInOut actionWithAction:[CCMoveTo actionWithDuration:0.7 position:randomEndPosition]];
but my sprite doesn't respond at all to this action!! my sprite doesn't have any b2body attached and seems like it respond to the tick: method of the physics world (which is in my Main Scene). How can i perform an action to a sprite that doesn't have a b2body attached.
any help would be appreciated!!! thanks
here is the entire code :
CCSprite *bubble = [CCSprite spriteWithFile:#"bubble.png"];
[self addChild:bubble];
CGPoint startPosition = ccp(100, 100);
bubble.position = startPosition;
CGPoint endPosition = ccp(400, 400);
id flyBubble = [CCEaseInOut actionWithAction:[CCMoveTo actionWithDuration:0.7 position:randomEndPosition]];
id remove = [CCCallBlockN actionWithBlock:^(CCNode *node) {
[self removeFruit:(CCSprite *)node];
}];
[bubble runAction:[CCSequence actions:flyBubble, remove, nil]];
I guess source and destination position of sprite is same. So no difference in action.
try like this..
sprite.position = ccp(0,0);
id flyBubble = [CCMoveTo actionWithDuration:0.7 position:randomEndPosition];
[sprite runAction:flyBubble];
i did a little mistake that costs me lot of times. it was in this line of code
id flyBubble = [CCEaseInOut actionWithAction:[CCMoveTo actionWithDuration:0.7 position:randomEndPosition]];
CCEaseInOut doesn't work i don't know why!! when i used CCEaseExponentialInOut it worked perfectly.
Thanks anyway!
I'm having really hard time with my pixelated 2D game. I'm using Cocos2D framework and the menu is driving me insane. I can change the setAliasTexParameters parameter with Sprites, but not for CCMenuItemImage.
I believe it is possible with CCMenuItemSprite, but I red you can't set it straight with that either and I can't seem to even get the menu work with CCMenuItem Sprites. It works nicely with CCMenuItemImages thought.
Here's the blurry buttons:
http://cl.ly/0i1V3Y0e3u2k1t102H2a
For some unknown reason the left arrow button is sharp. I tried to change achor points, positions and paddings by 1 and 0.5 pixels but it didn't help. All the button sizes are even numbers.
This is my code for one of the MenuItems:
CCMenuItemImage *buttonMoveL = [CCMenuItemImage itemFromNormalImage:#"buttonMoveLeft.png" selectedImage:#"buttonMoveLeft2.png" block:^(id sender) {
// Do something
}
}];
And this is the Menu itself:
ActionsMenu = [CCMenu menuWithItems: buttonAttack, buttonMoveL, buttonMoveR, buttonDefend, nil];
ActionsMenu.position = ccp(240, 38);
[ActionsMenu alignItemsHorizontallyWithPadding:8];
All help is really much appreciated!
I got it working by using sprites in the menus. Here's my solution:
CCSprite *spriteDefend1 = [CCSprite spriteWithSpriteFrameName:#"buttonDefend1.png"];
CCSprite *spriteDefend2 = [CCSprite spriteWithSpriteFrameName:#"buttonDefend2.png"];
CCMenuItemImage *buttonDefend = [CCMenuItemSprite itemFromNormalSprite:spriteDefend1 selectedSprite:spriteDefend2 block:^(id sender) {
// Do something cool
}
}];
i am spending a lot for my time for a simple things i think.I want to hide and show a sprite
in scene.
myS = [CCSprite spriteWithFile:#"Background_Pause_pad.png"];
[myS setPosition:ccp(384,470)];
myS.opacity = 0;
[self addChild:myS z:1];
and when i need to appear it..
[myS runAction:[CCFadeIn actionWithDuration:1]];
and hide it
[myS runAction:[CCFadeOut actionWithDuration:1]];
but it does not work.....can anyone plz help??
Why do you use a Sequence for one action ?
You have to choose the animation you want !
E.g : if you choose CCFadeIn
[mySprite runAction:[CCFadeIn actionWithDuration:0.5f]];
I think you can try the below stuff of the code. It would work for you
id action1 = [CCFadeIn actionWithDuration:1];
id action2 = [CCDelayTime actionWithDuration:1];
id action3 = [CCFadeOut actionWithDuration:1];
[myS runAction:[CCSequence actions:action1,action2,action3,nil]];
As you need the fadein fadeout action it would generate it and display the Same.
