Question

我有一个通过new PIXI.Sprite.fromImage(path)创建的精灵，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
];
