Status report and a video

I've been working hard trying to get the AStart (A*) pathfinding algorithm working as effectively as possible, but it's still not done yet.

Meanwhile, I've prepared for you a small video of the select box in action, just to show that there has been some progress in the past weeks.

The video as promised

Basic unit management

I've added an unit class structure similiar to the structure classes. It is now possible to add units to the field, select them for their information and give them a move order.

Moving keeps track of the facing of the unit and rotatets it as necessary. Well, actually the sprite is not rotated, but there are 32 different images of the same unit facing different directions. As the units move, thay push back the fog-of-war.


I'm going to make the units find paths using A* pathfinding, but for now the unit just goes x++, y++ until it reaches it's target. I recorded a video clip of the unit movement in action, but YouTube seems to be working slowly right now, so I'll just post the video once it get's processed.

A little video

Hi folks!

I've uploaded a quick video of the fog-of-war in action. Sorry for the quality, DivX wouldn't accept the file, so I compressed it with Windows Media 9...

Testing an early implementation of fog-of-war

This is an early implementation and might not be very efficent.

The idea is, that we have an array of integers that represents the maptiles and an array of integers that represents the tiles we are able to see. Then when we draw the tiles, we just check if it is visible or not.

Here's a picture with a vision radius of 5 tiles.


And here's another with vision radius set to 10 tiles.


Calculationg wether or not a point is within the visibility range is simple. The idea is from Java forums, but I trust most people can figure this out without any help.

Here's the formula:
if (Math.Pow((x1 - x), 2) + Math.Pow((y1 -y), 2) < Math.Pow(10, 2)) {
fogOfWar[x, y] = 1; //As in visible
}

the x1 and y1 are the coordinates of the center of the structure. The 10 in the end is the range of visibily, aka. the radius of the circle. And x and y are the coordinates of the point whichs visibility we are currently trying to determine.

Just a minor fix...

Forgot to show the structure information on the new interface...

New user interface

I've been working on a new user interface, sice the last one was really not that good.

It takes a lot of influence from Company of Heroes and C&C Generals. Here's a picture with no unit/structure selected:




And here's another one with a structure selected. The build-buttons -class renders all the available build options on the free slots on the interface. The build-buttons -class works together with the gameMouse -class to test if the button in beeing hovered.




I'm much more pleased with this new interface than with the old one, but making these cosmetic changes is newer a wise thing to do when theres still a whole lot of the game engine missing...
