问题描述



可以从侦听器内创建一个对象(某些类)吗?
我试过,但是我收到一个错误:``class not found''。



我想做一些类似的事情:

  class ONE {
class_ONE_code
}

class TWO {
object o = ONE)
}

我需要这个来创建一个新的监听器,当我执行另一个监听器。

解决方案

你希望做什么当然是可能的。您的代码中可能会出现语法错误。例如,您的类TWO的实现是无效的,因为类代码的成员声明部分中不能初始化类似o的成员变量。这只能在类方法中完成,如下面的示例代码所示。

  class One 
{
void DoClassOneAction(Object self)
{
OKDialog(执行一级操作);
}
}

class Two
{
Object oneInstance;

void DoClassTwoAction(Object self)
{
if(!oneInstance.ScriptObjectIsValid())
oneInstance = Alloc(One);
oneInstance.DoClassOneAction();
}
}

void main()
{
对象twoInstance = Alloc(Two);
twoInstance.DoClassTwoAction();
}

main();

请注意,DM脚本类的编码要求与支持对象的其他语言的编码要求有所不同。您可能需要查看DM在线帮助的脚本>对象部分中的详细信息(通过帮助>搜索...菜单项访问)。


I'm creating a script and have troubles.

Is it possible to create an object (of some class) from within a listener? I tried it but I get an error: ``class not found''.

I want to do something like:

class ONE {
    class_ONE_code
}

class TWO {
    object o = alloc(ONE)
}

I need this to create a new listener when I execute another listener.

解决方案

What you wish to do is certainly possible. Most likely you have a syntax error in your code. For example, your implementation of class TWO is invalid since a member variable like "o" cannot be initialized in the member declaration section of the class code. This can only be done within a class method, as illustrated in the example code below.

class One
{
    void DoClassOneAction(Object self)
    {
        OKDialog("Class One action executed.");
    }
}

class Two
{
    Object oneInstance;

    void DoClassTwoAction(Object self)
    {
        if (!oneInstance.ScriptObjectIsValid())
            oneInstance = Alloc(One);
        oneInstance.DoClassOneAction();
    }
}

void main()
{
    Object twoInstance = Alloc(Two);
    twoInstance.DoClassTwoAction();
}

main();

Note that the coding requirements for DM script classes differ somewhat from those of other languages that support objects. You may want to review details in the Scripting > Objects section of the DM on-line help (accessed via Help > Search… menu item).
