Well I've tweaked my itemMenu interface to make it a bit more friendly and to use the better vJass support for inheritance. The goal is same as before make easier to develop item menus and to stop having to worry about interoperability (i.e. what happens if I'm exiting from nuetralMenu vs exiting from menu2 vs exiting from menu3). Essientially there are 2 methods that every menu must implement onOpen & onInterupt, the interupt method fires when another menu B wants to take control of the item paine from menu A. Once A finishes closing the menu, B executes its onOpen method, which is like a setup variables method, and then B's menu is open. In more generic terms: B makes a request for A's resource (The item paine) and sleeps until it recieves the lock. A is notified, and executes whatever code it needs to do to give up the lock, and then gives up the resource to B. B is awoken and does all set up before recieving the resource. B then recieves the resource and set up events and code accordingly. Since warcraft 3 only has one thread execute at once, there is only one process wanting a held resource at any given time. The itemMenu also includes standard event responses that are commonly used in menu implementations including onItemUse,onItemDrop & onItemDrag. Which corresponds to using an item, dropping an item, or drag and dropping an item. If an item is used to completion use then drop are fired. These are all optional event responses. Built in, the following actions are taken: onItemUse Hitting Cancel will return to the Menu's exitmenu. Hitting NextPage will show the next page of the menu's content. onItemDrop will remove the item from the vector & redisplay the current page after a delay of 0 onItemDrag Will change the position of the dragged and droped item in the internal item vector. I have included in this demo a stat attributer to show a nontrivial example. I'm actually still abit annoyed as I want a real abstract class, as currently we get this wierdness.  JASS:Interface IClass method mustbeImplementedByAllChildren takes nothing returns nothing endinterface struct AClass extends IClass method mustbeImplementedByAllChildren takes nothing returns nothing //I have to implement this otherwise this won't compile! endmethod method usefulMethodForAllChildren takes nothing returns nothing //blah blah endmethod endstruct struct myClass extends AClass static string what="Oh, I guess I ddin't really need to implement mustbeImplemented!" endstruct Another annoying thing is the following JASS:interface Ibase method initStuff takes nothing returns nothing interface struct base extends Ibase method initStuff takes nothing returns nothing call BJDebugMsg("1") endmethod static method create takes nothing returns base local base b=base.allocate() call b.initStuff() return b endmethod endstruct struct child extends base method initStuff takes nothing returns nothing call BJDebugMsg("2") endmethod endstruct ... child.create() |
