I have added a function called PIXI.getJsonObject to get the json Data. Is it a good idea?

I had a lot of trouble trying to get the json data (due to the fact i couldn't get a spritesheet to work), so I added my own little function in PIXI.js called "PIXI.getJsonObject". I hope it is a good idea and a helpful function to anyone trying to get the Json data, But anyways here it is:

 

In "pixi.js" file i have added:

 

PIXI.assetJsonHolder = [];
 
PIXI.getJsonObject = function(id){
   
 
    for (var i = 0; i < PIXI.assetJsonHolder.length; i++){
        if(PIXI.assetJsonHolder.id === id){
            PIXI.assetJsonHolder.jsonData.length = PIXI.assetJsonHolder.length;
            return PIXI.assetJsonHolder.jsonData;
            break;
        }else{
            return null;
        }
    }
};
 
and in the :
PIXI.JsonLoader.prototype.onJSONLoaded = function () 
 
this is the change or add i have added
 

    var countFrames = 0;
                for (var i in frameData) {
                    countFrames++;
                    var rect = frameData.frame;
                    if (rect) {
                        PIXI.TextureCache = new PIXI.Texture(this.texture, {
                            x: rect.x,
                            y: rect.y,
                            width: rect.w,
                            height: rect.h
                        });
 
                        // check to see ifthe sprite ha been trimmed..
                        if (frameData.trimmed) {
 
                            var texture =  PIXI.TextureCache;
                            
                            var actualSize = frameData.sourceSize;
                            var realSize = frameData.spriteSourceSize;
 
                            texture.trim = new PIXI.Rectangle(realSize.x, realSize.y, actualSize.w, actualSize.h);
                        }
                    }
                }
                var jsonID = this.url.replace(this.baseUrl,'');
                PIXI.assetJsonHolder.push({id:jsonID, jsonData: this.json, length:countFrames});
 
and to call the function:
 
var jsonData = new PIXI.getJsonObject('jsonfile.json');
 
It works for me and i can get the jasonData i want. Give me a feedback and let me know what you think?

P.s i still can't get my spritesheet animation to work.

SebastianNette : Oh right i just cant seem to get the data to create a movie clip or a spritesheet. I keep getting error message, however i recently managed to get a movie clip animation working using the function i made

 

enpu: In pixi MovieClip and Spritesheet example (http://www.goodboydigital.com/pixijs/examples/3/ and http://www.goodboydigital.com/pixijs/examples/2/). You have to load the spritesheet then add an array of PIXI.Texture.fromFrame then add it to the movieClip to use: 

 

 

for(var i = 0; i < 29; i++){

      var texture = PIXI.Texture.fromFrame("Explosion_Sequence_A " + (i+1) + ".png");

      explosionTextures.push(texture);

}

 

var explosion = new PIXI.MovieClip(explosionTextures);

 

I thought it might be easier doing it with the json data just to loop adding the frame name using the json, Because in the Spritesheet for example you have a SpriteSheet.json loadded in and in that spriteSheet you have you have 4 different .png frames

 

 

var alienFrames = ["eggHead.png", "flowerTop.png", "helmlok.png", "skully.png"];

 

So instead of me typing it out and checking what .png i have i would just use the json to loop through and add that frame, but because i found it had to get the json i just added my own function to grab the json data. But since you guys say it isn't need could you give me an example how to use that PIXI.JsonLoader?
