Series Of Calculators - Component Programming(?)

Dec 29, 2011

I have an idea for a program that is, essentially, a series of calculators. These calculators are specific in their function and user data requirements but may be used independantly or perhaps sequentially. I am thinking along the lines of a "wizard" kind of interface but the user has the option to start, and/or end, at any point in the interface. Each calculator could be used independently, or may even recieve data from the calulcator that prefaces it. To complicate things even further, there may be more than one "wizard" pathway as there may be a variety of calculators in a variety of "threads" so to speak.

I'm thinking along the lines of a "component" style where each calculator, or "calculation thread", might be loaded in when the program starts. This way, I can build on the program over time or perhaps even control access to various components based on user previlages.

I am converting an old Vb6 solution to .net 2.0 in vs2010. I've been working in C# for about 3 years now and .net for 5. I don't recall having this problem in C#, but if I want initialize a readonly collection of DerivedControlFoo Is there a clean way to do it besides creating a sub to do it all off somewhere else? I'd love to be able to do it at the class level at the declaration for readability and simplicity.

I've created a component whose name I'd like to be able to change while editing in the component tray. I've added a Designer action for a name property, but now I'm stuck.

Looking at the property grid, I can see that the name property is parenthesised, indicating that it's not a regular property.

Game Programming :: Programming Such As OOP ?

Oct 30, 2011

I avidly create games in VB.net. Being a hobby programmer I give my games away for free. Since I'm a hobbiest without formal training I do try and educate myself on proper programming principles and follow them when programming such as OOP. There are however some things I have obviously missed being self-taught that perhaps I would know if I were formally educated. Once such issue that has really been my bane is how different classes (from now on referred to as objects) 'know' about each other WITHOUT programming specific interaction.

Okay imagine this, you have a space game and the following objects

[CODE]...............

Now each one of these objects has a Health, X,Y and Z private members and properties that are all inherited from clsSpaceEntity for argument sake. Now one way of programming collision between them would be to code out the following logic in the main game loop

[CODE].........................

Now this might seam okay if your talking about the simple example above but some of my games have tens or even HUNDREDS of objects that interact in this basic way. Is there a way in OOP to do the following... for each thing that inherits from clsSpaceEntity check against every other object that inherits this type (except itself) and if they collide then reduce health next? This sort of ability for a type of objects/class or whatever to be 'aware' of another and how they are the same/different and interact would save me tonnes and tonnes and TONNES of coding.

Averaging A Series Of Compass Readings?

Oct 19, 2009

If I have posted this question in the wrong forum, please tell me how to find the correct forum.

I am working on an application that presents the average of a list of compass readings. The readings are wind directions. The problem occurs when the wind is oscillating around North. Some of the readings will be in the 300's, other readings can be 1, 2, 10, etc. degress. (A compass reads from 1 to 360 degress. 360 degrees is the same as 0 degrees.

You can't just average the numbers. For example, if you had two readings, 355 degrees and 5 degrees, just averaging the two results in an answer of 180 degrees. The correct answer is either 360 degrees or 000 degrees.

Most likely I can code data analysis logic to look for the problem, but I am hoping there is a simplier way. Does anybody know the answer?
