Phaser-Nineslice plugin adds 9-slice scaling support to Phaser!
- Blazing fast
- Low memory usage
- Easy to use API
npm install @koreez/phaser2-nineslice --save
Load the plugin
You still need to load the plugin in your game. This is done just like any other plugin in Phaser. So, to load the plugin, include it in one of the Phaser States.
The plugin will patch your Phaser game with additional load/add/make methods so the nineslice container fits up in Phaser like any normal object!
Like any other asset in Phaser, you still need to preload the image. It's a bit different then a regular image, in the sense that it requires some extra data.
Apart from the key and the url, you can also specify the sizes of top, left, right and bottom sides.
If you don't specify a bottom size, it will use the value for the top. Same goes for right and left.
It's also possible to only give one size. If only one value is given, this will use that for the edges.
//This will load a 9-slice texture where all sides are 25pxgameload;//This will load a 9-slice texture where the// top is 10, left is 15, right is 20 and bottom is 30 pixels in sizegameload;
Adding a container
Also adding and creating of 9-slice containers is exposed through Phaser's GameObjectCreator and GameObjectFactory. So you can add a 9-slice container to your game just like any other image once it's preloaded!
//We specify the x and y position. the key for the image and the width and height of the container. It will be automaticly scaled!gameadd;
Or if you'd want to do something with it first:
//Two options here, first we use Phaservar container = gamecreate;containerx = 20;containery = 20;gameadd;//Or we use the Constructorvar nineSlice = game 0 0 'my-image' null 200 50;nineSlicex = 50;nineSlicey = 50;gameadd;
Using a Texture Atlas
It's also possible to use an image that's located inside a Texture atlas. The only difference then is that you don't have to preload the image, instead you use the object's constructor and pass the framedata directly on creation:
//Add an nineslice image with an texture atlasvar sliceButton =game // Phaser.Game150 // x position100 // y position'buttons' // atlas key'btn_clean.png' // Image frame200 // expected width100 // expected height//And this is the framedata, normally this is passed when preloading. Check README for detailstop: 20 // Amount of pixels for topbottom: 23 // Amount of pixels for bottomleft: 27 // Amount of pixels for leftright: 28 // Amount of pixels for right;thisgameadd;
9-slice container has a resize method which lets you expand/shorten the width or length of the image. When using resize method, make sure values are not lower than the width of the image corners
var sliceContainer = gameadd;sliceContainer;
