Unity 使用this关键字进行函数拓展 - GameObject
【摘要】
Example:
private void Start(){ var testComponent = gameObject .Activate() .Deactivate() .Name("") .Layer(0) .Layer("") .Tag...
Example:
-
private void Start()
-
{
-
var testComponent = gameObject
-
.Activate()
-
.Deactivate()
-
.Name("")
-
.Layer(0)
-
.Layer("")
-
.Tag("")
-
.GetComponentForcibly(typeof(LineRenderer));
-
-
bool isActive = testComponent
-
.Activate()
-
.Deactivate()
-
.Name("")
-
.Layer(0)
-
.Layer("")
-
.Tag("")
-
.IsActive();
-
-
}
