X11 Tools

3D Pong is three-dimensional version of the first arcade game, “Pong”, for the X Window System.

To play against the computer, run:
```
    $ 3dpong :0 --computer --sound
```
Angband: A roguelike game derived from Moria, based loosely on the books of J. R. R. Tolkien. The ultimate aim of the game is to advance in skill and strength, collecting better and more powerful magical items until you are ready to face the Master of the dungeon: Morgoth himself! Start the X11 mode with angband -mx11.
```
# pkg install games/angband
```
AppRes: Prints the resources seen by an application. It can be used to determine which resources a particular program will load.
```

```
ASClock: AfterStep clock with some language extensions.
```
# pkg install x11-clocks/asclock
```
Battalion: Battalion is a 3D game from 1994, originally written for the Silicon Graphics Indy UNIX workstation. The player controls a monster to blow up a city. The author dedicated a website to the game.

Depending on the perspective, the controls are a little awkward. You may want to change the camera with key 1, 2, 3, or 4. Use the mouse to rotate and to move forward/backward. The arrow keys only work if the mouse cursor is placed in the center of the screen. Shoot with the left control key or the left mouse button, and tilt the head with A and Z to target helicopters and jets. The camera can be rotated with I, J, K, and L. Alter the rendering details with D. Press G to grab the mouse cursor and P to pause the game.

I made a quick & dirty FreeBSD port based on the Linux version (no sound). Build and run Battalion with:
```
$ tar xfvz battalion1.4b-freebsd.tar.gz
$ cd battalion1.4b-freebsd/
$ gmake battalion CC=gcc
$ ./battalion
