GUI movie

The GUI is coming along pretty nicely. I got alignment implemented (you can align to a combination of left, top, right, and/or bottom. Left out-ranks right and top out-ranks bottom for simplicity.) I also implemented a Dialog class that can be moved, destroyed/closed, and resized. Oh, I also implemented the Label class.

One of the cool things is that since the bitmap font system already supports color formatters you can format the text via the text rather than a variable. For example I could do a rainbow text using:

MyButton.Text = "^0B^1u^2t^3t^4o^5n";
/*
Color values are set by the user, so they could be anything.
By default they're:
0xffffffff, // white, ^0, default
0xff000000, // black, ^1
0xffff0000, // red, ^2
0xff00ff00, // green, ^3
0xff0000ff, // blue, ^4
0xffffff00, // yellow, ^5
Color::FromArgb(255, 0, 64, 128), // ^6
Color::FromArgb(255, 255, 90, 90), // ^7
Color::FromArgb(255, 60, 255, 60), // ^8
Color::FromArgb(255, 220, 165, 65), // ^9
*/


Now, this next code is probably going to make no sense and look pretty bad, but oh well. Once I get the XML layout file done it'll be much easier to handle.

// My controls
// (X, Y, Width, Height, Text, ToolTipText, Parent, Manage /*this last one lets the system know if it should manage the memory for the control.*/)//

That's the code for the current movie.

There are some major design flaws in both my GUI system and my engine system, but that's what refactoring is for. BUT, that'll come later, after MalykAI is finished. I know there's a better way to design my GUI, but the system I've got set up works decently so I'll stick with it for now. I'm done refactoring things until after MalykAI is done.

Now, for the best part: THE MOVIE. Comments and questions are welcome!

I want to get a couple more controls finished before I release a demo. I've had a few friends test it and I THINK I've worked the rendering issues out. We'll find out in a few days.

Now I'm off to get some work done on MalykAI. I want to finish the gravity system off soon, but I have to get the entity system done before hand. So, I guess that's what I'll be doing for the rest of the night.

Not sure if it's just me, or perhaps Firefox, but all of your text is appearing the same colour as the background: black. [sad]


Crap, sorry I forgot about the white theme. I'll fix it! Thanks for the heads up!
