推荐答案

您必须将您的资产放在名为assets"的目录中.

You must put your assets within a directory called 'assets'.

看这个例子:

https://github.com/udhos/fugo/tree/master/demo/invader/assets

然后你就可以使用包golang.org/x/mobile/asset 加载所需资源:

Then you can use the package golang.org/x/mobile/asset to load the desired asset:

import "golang.org/x/mobile/asset"

f, err := asset.Open("image.png")

示例代码取自 https://github.com/udhos/fugo/blob/master/demo/invader/main.go:

func loadFull(name string) ([]byte, error) {
    f, errOpen := asset.Open(name)
    if errOpen != nil {
        return nil, errOpen
    }
    defer f.Close()
    buf, errRead := ioutil.ReadAll(f)
    if errRead != nil {
        return nil, errRead
    }
    log.Printf("loaded: %s (%d bytes)", name, len(buf))
    return buf, nil
}
