canvas - Cocos2d ClippingNode and Alphathreshold in Javascript / Browser -

-

i trying tp use png mask in cocos2d-js so:

this.mask=cc.sprite.create(cache.getspriteframe("bar_mask")); this.maskedfill = cc.clippingnode.create(this.mask); this.maskedfill.setalphathreshold(0.5);

but not work ... found in other posts, have enable stencil buffer ccsetupdepthformat: @gl_depth24_stencil8_oes

but have no idea how / in cocos2d-js

can help?

thanks!

it works me without additional depthformat settings. i'm using single-file engine cocos2d-js-v3.7.js here's minimal code (hope helps):

var game = cc.layer.extend({   init:function () {     this._super();      backgroundlayer =  cc.layercolor.create(new cc.color(40,40,40,255), 320, 480);      var target = cc.sprite.create("resources/doge.png"); /*child clip*/     var mask = cc.sprite.create("resources/doge-mask.png"); /*mask*/      var maskedfill = new cc.clippingnode(mask);     maskedfill.setalphathreshold(0.9);     maskedfill.addchild(target);     maskedfill.setposition(144, 224);      backgroundlayer.addchild(maskedfill,0);     this.addchild(backgroundlayer);    } });

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
