---------------------------------

0.1 Objective
The objective in the game is to navigate your spaceship through the
waypoints in each level. The next waypoint is shown on the radar,
which is the green box to the right. You have a limited amount of
fuel for travelling between waypoints, however, when you land on a
waypoint, your ship is refilled. You also have a limited amount of
laser shots which are also refilled. The fuel and ammo is shown as
two lines in the box next to the radar. The other lines in that box
is your velocity and the critical (maximum) velocity for a successfull
landing. Your ship will crash if the velocity is over the red lines.
When every waypoint in a level is completed, the game continues to the
next level.
The game will print out scores for each level to the standard output.

---------------------------------

0.2 Controls

F11: Toggle fullscreen on/off
F12: Take screenshot (saves in current dir, screenshot_XX.tga)
t: start new game
s: toggle between editor and game
ESC: Exit (or, if creating a polygon, cancel creation)
Mousewheel up/down: zoom in / out

In game controls:
t: start new game from starting level.
Arrow up : Thrust
Arrow Left/Right: Rotate ship
Space: Shoot laser
p: save (for the duration of the game) current position
o: restore (undefined behaviour if used before a game is saved)

Editor controls:
Left Mouse Button: Add/Edit/Drag
Right Mouse Button: Move around the board
0: Adding: Polygons
1: Collision detection on from the next verticy (default on)
2: Collision detection off from the next verticy (remember to put it on again
when wanted)
3: Landing platform (this can only be used to create entities, not to make part
of the level a platform)
4: Next verticy is white
5: Grey
6: Invisible (transperant)
7: Red
8: Green
9: Blue
q: Adding: The ship (Player start position)
w: Adding: Bases
e: Adding: enemies
d: Write the first polygon to verts.txt ("export that polygon for use as a
entity")
m: Adding: Mission waypoints.
n: Use the added mission waypoints. (Press after defining waypoints, overrides
existing)
g: save map to whichever level file.
t: start new game from starting level
del: remove polygon or entity
---------------------------------

0.3 Command line arguments
The game can take one or two optional arguments.
./osgg [NUM [DemoFile]]
NUM is the number of the level to start at.
DemoFile is the a demofile to be played back in this level, obviously,
to playback a demo, it is nessicary to tell in which level to do so.
Example, starting level 4:
./osgg 4
Example 2, starting level 2, load a demo called "demos/level2cool"
./osgg 2 demos/level2cool

This can be used so you don't need to play the same levels again and again.
This is also used when creating a new level. Do not use leading zeroes.
01 = wrong, 1 = right

Windows users need to edit winosgg.bat to apply the arguments

---------------------------------

1.0 Level Editing
Refer to the controls section to see how to do actions described here.

1.1 Level Elements
A level consists of:
Entities - Ship, Base, Enemy
Polygons - The enviroment, consist of verticies.
Waypoints - The Route that the player has to travel in order to complete the
level.

1.2 Polygons
Remember to select "Adding: Polygons"
Hover over a verticy of a polygon and press del to remove the polygon.
Polygons is a section of verticies, verticies are the points on the map
between which lines are drawn. A polygon can contain as many verticies as
desired, and in diffrent colors and with either collision detection on or off.
If collision detection is on on a verticy and the ship collides with the line
between that verticy and the next, the player dies. If the collision detection
is off, nothing happens, the ship flies right through that line.
To create a polygon, click where you want the first corner of the polygon,
then click to add more verticies, to finish the polygon, hold your mouse
over the first verticy and the curser changes color, click to complete.
After completing a polygon you can drag around the verticies if desired, hover
the cursor over a verticy, and the curser changes color, then hold mouse to
drag.

1.3 Entities
To add a entity, first choose the type of entity to add (you can only add one
ship)
Press where you want it placed, then hover over the small dot and drag it into
place.
To delete a entity, hover over it and press del.

1.4 Waypoints
Enter "Add waypoint" mode by pressing m
Hover over the base (the cursor changes color) which should be the first base
(the base on which the ship starts)
and click to add the start of the waypoints, then hover over the other bases and
click on those too, yellow lines are drawn between them.
When you are done, add the waypoint list to the map, by pressing n.
You can not edit waypoints, if you wish to define new waypoints for a allready
saved map, edit the game and enter the editor again.
