How to scale images for cocos2d game to iPhone/iPad (with and without Retina) -

-

i'm working on game in cocos2d (1.0.1), artist sent me psd project files, 3200x1800 resolution 300ppi. i'm supposed make ipad , iphone , without retina display. realised don't know nothing graphics. best way prepare images iphone , ipad (both hd , sd). should scale 480x320? should use apps texture packer? how without loss?

easiest way make graphics both ipad retina display , iphone retina display , use texture packer scale them automagically non-retina size each type of device.

as workflow iphone becomes:

  1. create retina graphics 640x960 display.

  2. use texture packer create textures retina version , use texture packer scale retina texture down lower-resolution device there.

  3. look @ how use resulting images , plists in cocos2d.

in regards #3 there tutorials here:

http://www.codeandweb.com/texturepacker/tutorials/#cocos2d

cocos2d @ handling point conversions between retina , non-retina versions of game. once tell use retina graphics if available can program game using standard 320x480 cocos2d point system , positioning work in bigger retina display enabled version. (or 768x1024 ipad version).

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
