Once one has the data, on can go ahead forward and call the defSprite function passing in the Image name as a Key, then the frame.x, frame.y, width, height, center data. Those are stored as negatives here so that one do not has to to do the mathematics later on when one draws Image. The reason for this is that one will use the cx and cy values a little later on, during rendering, to transform the Object into proper space. This Values are stored in the cx and cy as negative offset. ![]() So one multiplies the width as well as height times 0.5, which gives half the width and height. The next step is to actually define the center of the Image. From this one knows the Sprite Name and the Sprite Values. One need to fetch each key inside the dictionary and fetch the associated sprite Object that comes with it. The parsed Object has a frames dictionary that one can actually iterate over to load all of the sprites. This will return the text JSON data into an actual JavaScript object with members and values that one can iterate over. How to create sprite sheets & animations for PixiJS 6 Free tutorial: Create optimized animations & sprite sheets for PixiJS, speed up startup of your app, reduce download size. The first step that needs to be done is go through ad call JSON.parse on that. Tutorials for other frameworks are available from the tutorials list.

TutorialsCommunity AnswersKnowledge BaseForumsAsset StoreTerms of use. Given a data file one need to load the assets into a sample by filling out the parseAtlasDefinition function in the spreadsheet class. One need to use all 4 values to actually draw the char to the canvas. The next two are width and height, which represent the size of this chart in the Atlas itself. The first two, x and y, represent the top left corner of the chart inside the Atlas. The frame ahas 4 parameters that one needs to care about. This image should give you an idea about this tools's. TexturePacker has some Pro features, but this tutorial limits itself to its free features. ![]() ![]() It packs single images together into one big spritesheet, so you don't need to do this manually. Secondly, is the data in the frame parameter. The first tool you need is TexturePacker. The first, being the name of the chart, which is the name of the original loose asset before it was packed inside a atlas. Primarily one is really only concerned with two things. For each chart in the atlas, the JSON file list a nice set of data, that allows to understand more about this chart. One need to load and parse the data in this file, in order to render all the sprites on the screen properly. The output of texture packer is a JSON file.
