在AS3中应用双色变换

Question

简单地说，我想为几个影片剪辑设置不同的特定颜色，然后在它们上面应用一个色调。

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重置了该值。有办法保持第一个颜色变换的值吗?

您应该能够使用ColorTransform.concat()函数完成此操作。

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将偏移量值箝位到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:

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);

我找到了一个解决这个问题的方法。

如果我设置一个对象的颜色

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

然后我可以编辑蓝色和绿色的值，以便得到我想要的颜色

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;
