Cocos2D-js : Put the camera to the center of the map


Cocos2D-js : Put the camera to the center of the map

wish help you to fix your issue There is no such function, but you can use setPosition(x, y) function of you map(its base class is CCNode) to put it in the right place and make the "camera" to the center of the map.
For example, if your map size is (w1, h1), and window size (cc.director.getWinSize()) equals (w2, h2). Assume w1 >= w2 and h1 >= h2. Assume the anchor point of map is cc.p(0,0). So we can put the map in center by
code :
map.setPosition(-(w1 - w2)/2, -(h1 - h2)/2)

it helps some times Yes, CCCamera would work. However, it has some drawbacks that make it undesirable for some uses. Moving the layers respectively all other objects relative to that sprite may be a better solution. It depends on the game.
First, read up what the different approaches and their drawbacks are, you can get a lot out of this cocos2d forum thread: http://www.cocos2d-iphone.org/forum/topic/5363

hope this fix your issue What is the best way I center the screen to follow the character? Should I use CCCamera or just move the background around? , Try this...
code :
[self runAction:[CCFollow actionWithTarget:(your hero) worldBoundary:CGRectMake(0,0,1050,350)]];

should help you out My suggestion: don't use the CCCamera.
Your game design requires the car to move over a track. In programming terms this is often much easier accomplished by keeping the car static, and instead moving the background underneath.

wish of those help Obviously this is far too late for you to use, but for anyone looking at this by googling "cocos2d isometric transformation rotate skew" or something like that like I was: I figured out the right skews and rotations. A two-layer approach was needed due to the lack of a diagonal scale or Z rotation. For javascript devs: this makes an isometrically transformed DrawNode. I'm not sure what performance impact this has, but since it's only using the native functions I don't believe it has much if any. For other languages, it should be trivial to port.
code :
var MapContainer = cc.Layer.extend({
  ctor: function(){
    this._super();

    this.scaleX = .947;
    this.setAnchorPoint({x:0, y:0});
    this.drawNode = new MapDrawNode();
    this.addChild(this.drawNode);

    return true;
  },
  drawNode: null
});
var MapDrawNode = cc.DrawNode.extend({
  ctor: function(){
    this._super();

    this.setAnchorPoint({x:0, y:0});
    this.y = 360; // shifts everything up, adjust as needed. Mine is 1/2 window size
    this.transform();

    // Your init code here

    return true;
  },
  transform: function(){
    this.setScaleX(0.81649658);
    this.setScaleY(0.81649658);
    this.setSkewX(16.3);
    this.setSkewY(16.3);
    this.setRotationY(45);
    this.setRotationX(45);
  }
});
