SPRITE SHEET JSON DEFINITION TEXTUREPACKER CODE
Step #5- Drag the plist and image into your game and write code to load them. Step #4- Click save and then click publish! Step #3- (Optional) Turn off rotation, trim, etc. Step #2- Open finder and drag your sprites onto the right side of Texture Packer In this example, I’m saving to my desktop. Step #1- Start texture packer and quickly enter the data file and image file (top left).
SPRITE SHEET JSON DEFINITION TEXTUREPACKER HOW TO
Still not sure? Here’s how to make a sprite sheet with texture packer (MAC version) in about 30 seconds: – Exports metadata for just about any format you need (Cocos2d, Corona, Sparrow, LibGDX, LimeJS, Ogre, Moai, CSS, JSON or make your own) gamedev channel image unity game-development image-processing unrealengine texturepacker unreal-engine rgba texture-pack texture-mapping texture-merge.
SPRITE SHEET JSON DEFINITION TEXTUREPACKER SOFTWARE
– Export to PNG, JPG, PVR (iPhone native format), PVR.CCZ (Cocos2d), PVR.gz (PVR gzipped) and KTX Software to merge (or pack) textures into image channels, producing one image with up to four textures. – Import PSD, PNG, JPG, SWF, TGA, BMP, TIFF – Color Reduction (dithering, 16 bit conversion, etc.) – Rotation (to help fit your sprites even tighter) – Trimming (remove whitespace on individual sprites – very handy!) There are plenty of advanced options if you want to get fancy, such as: Simply drag and drop your png files to the app and that’s it. To load a sprite sheet with JSON we can use the atlas statement and pass in a key. 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.I’ve been using TexturePacker to do all the sprite sheets for my iOS games and so far I have been impressed. The software I use to create animations is called Texture Packer. 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. The first step that needs to be done is go through ad call JSON.parse on that.
Given the atlas JSON data that has been loaded from the xhr request. 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. Secondly, is the data in the frame parameter. The first, being the name of the chart, which is the name of the original loose asset before it was packed inside a atlas. 1 To get started with game development I purchased some top-down sprite assets which come arranged in a grid, but to use them with a typical 2D rendering engine (I'm using Pixi.JS ), I need a JSON file tracking the coordinates and dimensions of the grid the assets are arranged onto (which was not included in the package I purchased). 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. (This works the other way around as well. You can click on a specific asset in that list and it will highlight in the sheet. As you can see, they instantly appear in your sheet. Currently SpriteWidget supports sprite sheets in json format and produced with a tool such as TexturePacker. The first thing to do is open your folder with your magical art, and drag and drop it into Texture Packer's assets list. This saves space in the device's gpu memory and also make drawing faster. The output of texture packer is a JSON file. Using a SpriteSheet you can pack several texture elements within a single image.
