pixi-heaven v0.4.0

pixi-heaven

This is heaven for sprites. Want to color them better? Wanna use advanced colors? Its all here!

Works with PixiJS v6

For v5 please see v6.x branch, npm version 0.3.3 For v5 please see v5.x branch, npm version 0.2.3 For v4 please see v4.x branch, npm version 0.1.21

Examples

Done:

• Advanced color modes
• Polygon packing
• Mesh with trimmed textures

Migration

To use es6 modules in IDE, its better to have distinct class names. That's why PIXI.heaven.Sprite is now SpriteH, same with SimpleMeshH and BitmapTextH

How to use

Just add pixi-heaven.js file in your build.

import { SpriteH } from 'pixi-heaven';

var sprite = new SpriteH();
// good old sprite tint
sprite.color.setLight(0.5, 1.0, 0.5);

// dark tint - new feature
sprite.color.setDark(0.2, 0.2, 0.2);

// change single component, useful for tweening
sprite.color.darkG = 0.1;

Or convert PIXI sprite. In that case, make sure that you actually use heaven Sprite somewhere, or it'll be tree-shaken away.

import { Sprite } from 'pixi.js';

var sprite = new Sprite(someTexture);

// pixi vanilla way, optional
sprite.tint = 0x80ff80;

// activate the plugin!
sprite.convertToHeaven();

Useful example: invert the colors

sprite.color.setLight(0, 0, 0);
sprite.color.setDark(1, 1, 1);

Make whole sprite of one color:

sprite.tint = 0xffaacc;
sprite.color.dark[0] = sprite.color.light[0];
sprite.color.dark[1] = sprite.color.light[1];
sprite.color.dark[2] = sprite.color.light[2];
//dont forget to invalidate, after you changed dark DIRECTLY
sprite.color.invalidate();

Meshes

Heaven meshes SimpleMeshH can be used with trimmed textures.

Unfortunately, meshes cant be converted, you have to create mesh instead of PIXI.SimpleMesh

That adds extra shader switched, and disables batching, but it shows correct result!

To switch it off, set

import {settings, CLAMP_OPTIONS} from 'pixi-heaven';
// Default, PixiJS vanilla mode
settings.MESH_CLAMP = heaven.CLAMP_OPTIONS.NEVER;

To always use the trimmed texture shader, set

import {settings, CLAMP_OPTIONS} from 'pixi-heaven';
// Default, PixiJS vanilla mode
settings.MESH_CLAMP = CLAMP_OPTIONS.ALWAYS;

Mesh batching works the same way as in pixi.

PIXI.Mesh.BATCHABLE_SIZE = 1000; // bigger meshes now are batched too!
PIXI.Mesh.BATCHABLE_SIZE = 1; // or not.

How to use with spine

This plugin enables light-dark tint of spine >= 3.6.

Mixin can be applied to any spine prototype class: SpineBase, Spine or your own extended class. Usually its applied to SpineBase.

Light-dark tint works like in sprites.

import {SpineBase} from '@pixi-spine/base';
import {applySpineMixin} from 'pixi-heaven';

applySpineMixin(SpineBase.prototype);

spine = new Spine();
spine.color.setLight(0.5, 1.0, 0.5);
spine.color.setDark(0.2, 0.2, 0.2);

batch ADD blending mode with NORMAL

This feature comes from unity spine runtime - ADD can be emulated by NORMAL with zero tint alpha. It reduces number of batches and drawcalls.

import {settings} from 'pixi-heaven';
settings.BLEND_ADD_UNITY = true;

Animation

Thanks to @finscn, unlike pixiJS vanilla AnimatedSprite, here animation is a component:

import {AnimationState} from 'pixi-heaven';

new AnimationState(frames).bind(sprite);
sprite.animState.gotoAndStop(2);

It still uses PIXI.Ticker.shared if you dont specify autoUpdate=false. It will be stopped and destroyed with the bound element.

How to mask sprites with sprites

Plugin adds special renderer that has faster masks than just sprite.mask. It also works on heaven meshes.

import {SpriteH} from 'pixi-heaven';

sprite = new SpriteH();
sprite.maskSprite = sprite2; //set it
sprite.pluginName = 'batchMasked'; //enable special plugin rendering
sprite2.renderable = false; //turn off rendering

Batching works with spine, just enable maskSprite in any sprite or mesh of spine instance, all pluginName's will be adjusted automagically.

Look at Spine file to see how it actually works.

Vanilla JS, UMD build

All pixiJS v6 plugins has special umd build suited for vanilla. Navigate pixi-heaven npm package, take dist/pixi-heaven.umd.js file.

<script src='lib/pixi.js'></script>
<script src='lib/pixi-heaven.umd.js'></script>

all classes can be accessed through PIXI.heaven package.

Building

You will need to have node setup on your machine.

Then you can install dependencies and build:

npm i
npm run build

That will output the built distributables to ./dist.
