我正在测试'SELECT id, title, author, price FROM books ORDER BY '.$order.' ASC'
组件（https://github.com/wmurphyrd/aframe-super-hands-component）来移动对象。同样，我正在设置// CommonNullifier is able to nullify its common field(s)
type CommonNullifier interface {
NullifyCommon()
}
// StructCommon contains the common struct fields
type StructCommon struct {
Common string
}
func (sc *StructCommon) NullifyCommon() {
sc.Common = ""
}
// Struct1 embeds common fields, thus implements CommonNullifier
type Struct1 struct {
StructCommon
Foo string
}
// Struct2 also embeds common fields, thus also implements CommonNullifier
type Struct2 struct {
StructCommon
Bar string
}
// NullifyCommon nullfies the 'common' fields in the argument
func NullifyCommon(s CommonNullifier) {
s.NullifyCommon()
}
手势组件。我要注意的是，一旦移动了对象，就无法“消除”移动的对象。它仍然处于可抓取状态。代码很简单
super-hands
是否需要设置某些内容以禁用可抓取状态？
