Go 方法参数和 float64 数组给出意外错误

Question

编译以下代码时...package cameratype camera struct {    position [3]float64    viewWidth int    viewHeight int}func (c camera) SwitchToCartesianThreeSpace(x, y int) [3]float64 { // LINE 9    var x3 float64 = 0 // view is set to the origin    var y3 float64 = float64(x) - (float64(c.viewWidth) / 2)    var z3 float64 = float64(-y) + (float64(c.viewHeight) / 2)    result := [3]float64{x3, y3, z3}                               // LINE 13    return result}...出现以下错误。camera/camera.go:9: undefined: xcamera/camera.go:9: undefined: ycamera/camera.go:11: undefined: xcamera/camera.go:12: undefined: ycamera/camera.go:13: cannot use x3 (type float64) as type [3]float64 in array elementcamera/camera.go:13: cannot use y3 (type float64) as type [3]float64 in array elementcamera/camera.go:13: cannot use z3 (type float64) as type [3]float64 in array element到目前为止，我已经编写了相当多的 Go 代码，但不明白为什么会出现第 9 行的错误或第 13 行的错误！有谁能解释一下吗？

在 playgroud 中隔离，它编译得很好，并具有预期的输出：

c := camera{}

res := c.SwitchToCartesianThreeSpace(2, 3)

// res is [0 2 -3]

您需要尝试只camera.go包含该代码，或检查文件如何适合您当前的工作区。camera.go
