在 AS3 中应用双色变换

Question

简而言之，我想将几个动画片段设置为不同的特定颜色，然后对它们应用色调。

var color1 = new ColorTransform(); color1.color = 0x0000FF;
var color2 = new ColorTransform(); color2.color = 0x00FF00;
var color3 = new ColorTransform(); color3.color = 0xFFFF00;

thing1.transform.colorTransform = color1;
thing2.transform.colorTransform = color2;
thing3.transform.colorTransform = color3;

thing1.transform.colorTransform = new ColorTransform(1, 1, 1, 1, 0, 200, 150, 0);
thing2.transform.colorTransform = new ColorTransform(1, 1, 1, 1, 0, 200, 150, 0);
thing3.transform.colorTransform = new ColorTransform(1, 1, 1, 1, 0, 200, 150, 0);

不幸的是，colortransform 重置了值。有什么方法可以保持第一个颜色变换的值？

您应该可以使用 ColorTransform.concat() 函数来做到这一点。

var color1 = new ColorTransform(); color1.color = 0x0000FF;
var color2 = new ColorTransform(); color2.color = 0x00FF00;
var color3 = new ColorTransform(); color3.color = 0xFFFF00;

color1.concat( new ColorTransform(1, 1, 1, 1, 0, 200, 150, 0) );
color2.concat( new ColorTransform(1, 1, 1, 1, 0, 200, 150, 0) );
color3.concat( new ColorTransform(1, 1, 1, 1, 0, 200, 150, 0) );

thing1.transform.colorTransform = color1;
thing2.transform.colorTransform = color2;
thing3.transform.colorTransform = color3;

本质上与（使用 Math.min 将偏移值钳位到 255）相同：

thing1.transform.colorTransform = new ColorTransform(1*1, 1*1, 1*1, 1*1, Math.min(0x00+0, 0xFF), Math.min(0x00+200, 0xFF), Math.min(0xFF+150, 0xFF), Math.min(0x00+0, 0xFF));
thing2.transform.colorTransform = new ColorTransform(1*1, 1*1, 1*1, 1*1, Math.min(0x00+0, 0xFF), Math.min(0xFF+200, 0xFF), Math.min(0x00+150, 0xFF), Math.min(0x00+0, 0xFF));
thing3.transform.colorTransform = new ColorTransform(1*1, 1*1, 1*1, 1*1, Math.min(0xFF+0, 0xFF), Math.min(0xFF+200, 0xFF), Math.min(0x00+150, 0xFF), Math.min(0x00+0, 0xFF));

或者：

thing1.transform.colorTransform = new ColorTransform(1, 1, 1, 1, 0x00, 0xC8, 0xFF, 0x00);
thing2.transform.colorTransform = new ColorTransform(1, 1, 1, 1, 0x00, 0xFF, 0x96, 0x00);
thing3.transform.colorTransform = new ColorTransform(1, 1, 1, 1, 0xFF, 0xFF, 0x96, 0x00);

Answer 2

我找到了解决这个问题的方法。

如果我将对象设置为颜色

var color1 = new ColorTransform(); color1.color = 0x0000FF;
thing1.transform.colorTransform = color1;

然后我可以编辑蓝色和绿色值以获得我想要的色调

color1.blueOffset+=200;
color1.greenOffset+=150;

然后在对象上使用 colortransform 来设置新颜色

thing1.transform.colorTransform = color1;
