在PIXI.js中如何增加精灵的亮度？

Question

我有一个精灵通过创建new PIXI.Sprite.fromImage(path),我怎样才能实时提高它的亮度？

Answer 1

您可以使用PIXI ColorMatrixFilter执行此操作:

var colorMatrix =  [
    1,0,0,0,
    0,1,0,0,
    0,0,1,0,
    0,0,0,1
];
var filter = new PIXI.ColorMatrixFilter();
filter.matrix = colorMatrix;
stage.filters = [filter];

较暗:

var colorMatrix =  [
    1,0,0,-0.5,
    0,1,0,-0.5,
    0,0,1,-0.5,
    0,0,0,1
];

打火机:

var colorMatrix =  [
    1,0,0,0.5,
    0,1,0,0.5,
    0,0,1,0.5,
    0,0,0,1
];
