I've been trying to extend the functionality of TweenManager, so it can resume and pause everything within a group. I adapted the code from here: http://jsfiddle.net/lewster32/L3u3gp5k/ http://docs.phaser.io/TweenManager.js.html#sunlight-1-line-127 When debugging with console, _tweens and _add are undefined for each object, so the function doesn't work. I think the code is correct? Any ideas why this isn't working? I'm guessing i've missed something crucial about _tweens. Here's the code: (This goes out to Rich and Lewster) Phaser.TweenManager.prototype.pauseAllFrom = function(obj, children) {console.log('pauseAllFrom', obj.type, obj.name, obj._tweens, obj._add); var o, c, t, len; if (Array.isArray(obj) ) { for (o = 0, len = obj.length; o < len; o++) { this.pauseFrom(obj[o]); } } else if ( (obj.type === Phaser.GROUP || obj.type==7) && children){ for (c = 0, len = obj.children.length; c < len; c++){ this.pauseFrom(obj.children[c]); } } else { for (t = 0, len = this._tweens.length; t < len; t++){ if (obj === this._tweens[t]._object){ console.log('pauseFrom _tweens:',this._tweens[t]); this._tweens[t].pause(); } } for (t = 0, len = this._add.length; t < len; t++){ if (obj === this._add[t]._object){ console.log('pauseFrom _add:',this._add[t]); this._add[t].pause(); } } }};Phaser.TweenManager.prototype.resumeAllFrom = function(obj, children) {console.log('resumeAllFrom', obj.type, obj.name, obj._tweens, obj._add); var o, c, t, len; if (Array.isArray(obj) ) { for (o = 0, len = obj.length; o < len; o++) { this.pauseFrom(obj[o]); } } else if ( (obj.type === Phaser.GROUP || obj.type==7) && children){ for (c = 0, len = obj.children.length; c < len; c++){ this.pauseFrom(obj.children[c]); } } else { for (t = 0, len = this._tweens.length; t < len; t++){ if (obj === this._tweens[t]._object){ this._tweens[t].resume(); } } for (t = 0, len = this._add.length; t < len; t++){ if (obj === this._add[t]._object){ this._add[t].resume(); } } }};I also had to add a condition for the object type, as the console wasn't recognising Phaser.GROUP, and spitting out a number for each object type. // from thiselse if (obj.type === Phaser.GROUP && children){// to thiselse if ( (obj.type === Phaser.GROUP || obj.type==7) && children){Any help would be greatly appreciated. Thanks
