onTouchesBegan touches is value 2.1.3-v2.1

onTouchesBegan function:

in v2.1

code:
var location = touches[0].getLocation();
console.log(location);
console.log(cc.Rect.CCRectGetMinX(this.paizi.getBoundingBoxToWorld()));
console.log(cc.Rect.CCRectGetMaxX(this.paizi.getBoundingBoxToWorld()));
console.log(cc.Rect.CCRectGetMinY(this.paizi.getBoundingBoxToWorld()));
console.log(cc.Rect.CCRectGetMaxY(this.paizi.getBoundingBoxToWorld()));
result:
x: 60 y: 309
4
260
632
749

but in v2.1.3

result :
x : 64.324634242 y:313.23089234
4
260
632
749

so ,i don’t know why arenot touches[0] value is diffent?

v2.1.3 is not getBoundingBoxToWorld but i add getBoundingBoxToWorld to webgl CCNode.js 。。。。

same code in v2.1 andr v2.1.3 , use CCRectContainsPoint question is diffent, fuck
