[英]Unity : I can't change the opacity of an image or change its color in RGB
In my project, I want to change the color of a square at runtime which is simply a game object with an Image
component.在我的项目中,我想在运行时更改正方形的颜色,这只是一个带有
Image
组件的游戏 object。 In my script I proceed like this:在我的脚本中,我是这样进行的:
private Image imageRenderer;
imageRenderer = ImageCompleteSquat.GetComponent<Image>();
imageRenderer.color = Color.red;
In this case, it works and the image turns red as expected.在这种情况下,它可以正常工作,并且图像按预期变为红色。 But as soon as I change this line by putting my own RGB color like this:
但是一旦我通过像这样放置自己的 RGB 颜色来更改此行:
imageRenderer.color = new Color(227, 66, 52);
The image is not displayed anymore: it disappears.图像不再显示:它消失了。 Does anyone know how to change the color of an
Image
component?有谁知道如何更改
Image
组件的颜色?
you might want to set the alpha value first你可能想先设置 alpha 值
imageRenderer = ImageCompleteSquat.GetComponent<Image>();
var tempColor = Color.red;
tempColor.a = 1f; // change this value (floating point between 0 and 1)
imageRenderer.color = tempColor;
From the docs of Color
, each color component is a floating point value with a range from 0
to 1
.从
Color
的文档中,每个颜色分量都是一个浮点值,范围从0
到1
。 Hence just divide the arguments passed into Color()
by 255因此只需将传递给
Color()
的 arguments 除以 255
imageRenderer.color = new Color(227/255f, 66/255f, 52/255f);
