I have instances of Class A and Class B and need help with the hitTest logic between the two on them.
When I drag an instance of Class B on stage I want any instances of Class A which will come on stage by AS3 will be automatically called by object instances of Class B for hitTestObject with A. I cannot create array (predefined & code compression) point.
I have already did this in past but forgot syntax arrangement.. but I am pretty clear how it was done.
Created class A
created method to let target this.
Created class B
import A
call method from A to find object
do hitTestObject
please help me out in the flow
Need this in ActionScript 3.0;

I have one class that I put the Boolean in but I need to use it
In a different class so can anyone tell me what to do
To get the boolean to work for the other classes to

First of all check this post, we discourage screenshots of code and/or errors so please post code in future instead of screenshot.
From screenshot on is non-static data member of playbutton class. You can't use non-static data member in all class.
You need an object of playbutton, if you want to access any non-static data member.
playbutton x=new playbutton();
x.on=true;
I'll recommend you to follow naming conventions in java for better coding experience.
Pretty new to matlab. I want to have a class, which does some calculation. I want to import this class in another class( not instantiate). and use the functions as default functions.
This did not help me much. Can we import a user defined class/functions?
So you have a class calculationClass, and you want to create another class otherClass that can access the calculations provided by calculationClass
One way that works if the calculations are either normal or static methods would be to subclass calculationClass, i.e. start your class definition with
classdef otherClass < calculationClass
[some code here]
end
This way, all methods of calculationClass immediately become available to otherClass. Note that if calculationClass has a nonempty constructor, the subclass will call the constructor as this = this#calculationClass.
If the calculations are static methods only, you can, alternatively, access those calculations as calculationClass.someCalculation(inputArguments), or create a package and use import.
In PowerMockito, we can use the pattern "whenNew(MyClass).thenReturn(mockMyClass)" when someone wants to new an instance of MyClass, it will receive mockMyClass instead of the real instance.
Can we do similar things in ScalaMock or EasyMock? I spent whole day for this issue.
This is my scenario, I have two classes A and B. Inside class A, it will new an instance of class B.
Now I want to test class A, and when class A creates a new instance of class B, what I want is to return a mock object of class B (not the real class B).
In Java, I can handle this issue easily with PowerMock and JUnit, but I cannot do it in Scala.
For EasyMock, it is not directly possible. You need to use PowerMock. See here
Is the following format wrong if I add a pointer to an object of a class, as data attribute of class in Class diagram in UML?
could not find anything about using objects in class diagram, is
underlining the object correct within the class attributes?
I think you may be mis-understanding classes, objects and attributes. Apologies if it's me doing the mis-understanding. So. Here's the short answer:
it's absolutely fine and normal for the type of an attribute to be a Class. In other words, you're not restricted to using primitive types like int, long, char etc.
The consequence is, as you say, that the values of those attributes at run time will themselves be objects. Specifically, instances of the classes Ability, Move and See.
More specifically, each instance of Agent (i.e. each Agent object) will hold references - or more precisely pointers - to 3 other objects: one instance each of Ability, Move and See.
So, assuming that's right, what you have is correct - except for the underlining.
Underlining an attribute or operation says it sits at the class level - not the instance level. It's the equivalent of static in java. Think of declaring constants in class scope, or constructors.
If I understand your model that's not what you want. You want each instance of Agent to hold (a pointer to) its own instances of Ability, Move and See. You don't want all the Agent objects to share the same 3 instances. Assuming so, you don't need the underline.
Hope I understood and that helps.
I'm trying to implement a plugin system using MAF. The objects I want to pass currently aren't serializable though, and even though I'm sure I could make them serializable I don't think it would be very performant.
Two questions:
1) In order for MAF to pass the actual references across, does an object simply need to inherit from MarshalByRefObject or is there more to it than that?
2) Could I wrap my class in an object that inherits from MarshalByRefObject to get the reference across?
EDIT: Obviously the problem itself has little to do with MAF, but I just wanted to include some context in case someone could point me in an altogether direction to go.
1) Yes, it just needs to inherit from MarshalByRefObject, but any public types inside the class also need to be serializable or inherit from MarshalByRefObject as well.
2) No, this just pushes the problem back since the class still needs to be serializable or inherit from MarshalByRefObject.
