请教一个百思不得其解的简单问题.

Creator 3.x
#1

我用的是cocos create 3.8.8

const graphics = this.getComponent(Graphics)

    if (!graphics) return

    graphics.fillColor.fromHEX('#ff0000');

    graphics.circle(0, 0, 100)

    graphics.fill()

以上代码可以画出红色的圆.

const graphics = this.getComponent(Graphics)

    if (!graphics) return

    graphics.fillColor.set(1, 0, 0, 1)


    graphics.circle(0, 0, 100)

    graphics.fill()

以上的代码却是漆黑一片,

我知道问题出在 graphics.fillColor.set(1, 0, 0, 1)
但是不知道为什么会不行

#2

真心求解,头都大了

#3

fillColor = Color("") 这样？

#4

graphics.fillColor.set(255, 0, 0, 255)

0~255，不是 0~1，试一试
