R-THETA is an original game concept, made in the style of the old Atari console games of the late 1970's. The gameplay is simple: you must prevent your rotating radar-scope line from hitting enemies. To do this, you control a shooter on the radar-scope that can move toward and from the centre of the radar scope, and shoot the enemies. As you shoot more enemies, your radar-scope line rotates faster, making the game increase in difficulty.
Because this game is based in polar coordinates, (rather than an x-y grid) your shots do not fire in a straight line. Instead, they maintain a constant distance from the centre and circle around. Also, the movement controls do not move the shooter left, right, up or down, but instead control its distance from the centre.
Though this might sound confusing, the game is very easy to get used to, and it becomes almost second nature.
<UP ARROW>: Increase shooter's radius amount (move it away from the centre of the radar-scope)
<DOWN ARROW>: Decrease shooter's radius amount (move it toward the centre of the radar-scope)
<SPACE>: Fire a shot
<SHIFT>: Invert controls. (This might be useful for some players when the radar-scope line is 'upside down,' although I do not personally use it)
<ENTER>: Pause the game.
There are a variety of other controls options described in the README, to fit many playing styles. (I personally prefer moving with <W> and <S> and shooting with <CTRL>)
While my XP was incapacitated, I decided to work on Game Maker 6 on my Windows 98. I wanted to make a simple, original, and artistic game that would fit onto a floppy disk. Thus, R-THETA was born.
-Because of the small resolution of the game, it is not recommended that you interpolate pixels.
-There are no set colours for this game. The game generates a random RGB value for drawing the various shapes. There is no saturation, so all the colours are bright and fully visible.
-There is also no set music for the game. I generated sine wave tones to fit scales that would sound good when the individual notes are played at random. This does not generate a "song," but instead a musical idea.
- A major graphics problem with this game was the interpolation (i.e. the 'blurring' of close-together pixels) that many newer machines perform. Ultimately, the game should look exactly like the screenshot, with no blurry pixels, as it does on my Windows 98. To attempt to get close to this, I decided to make it set the resolution to 320 x 240, as it is the smallest I could manage. If anyone knows how to set it smaller than that, please let me know. I couldn't even with code. To all who for some reason hate resolution setting games: I'm sorry, but it looks better now because there is less interpolation.
Please let me know what you think of this concept. Again, the controls take only a short time to get used to, but this only adds to the unique gaming experience.
Also, please post your high scores, as it helps a lot with setting the game's difficulty and "learning curve." Thanks a lot!
