Arduboy large open-world procedurally generated city motorcycle game with 3 play modes.
- The city is 256x256 blocks with each block being 64x64 tiles and each tile is 8x8 pixels.
- Assuming a block is 100m, then the random city is about the size of El Paso, TX
- 100m/block * 256 block = 25.6km ~= 15.9 miles
- (15.9 miles)2 = 252.8 miles2
- El Paso is about 255.2 miles2
- The city is generated from a random seed. But a given seed will always produce the exact same city.
- The underlying algorithm uses an LFSR (linear feedback shift register) for the random element, but for a given seed the sequence is always the same.
- Currently using a 20-bit LFSR (4 bits for a block x 256 blocks wide x 256 block high -> 20 bits.
- Could easily use larger LFSR for larger maps. (32 bits would allow a 16k by 16k city with 4 bit blocks)
- Left/Right buttons turn
- B button accelerates each time it is pressed
- A button brakes each time it is pressed
- Going off road will stop the motorcycle. To get back on the road, press B repeatedly.
- Holding the Down button and pressing A will pause the game and allow the player to resume or exit.
- Free Play - expore the city at your own pace.
- Race to the Edge - start out in the middle of the city and try to reach any edge as fast as you can.
- Fastest times are stored along with the map seed so you can try to beat your record or get share your seed with a friend to see if they can do better.
- Crazy Courier - pick up randomly placed packages. The faster you pick them up, the more points you get. But if the timer reaches zero, its game over.
- Highest scores are saved along with the map seed.
- Records - see the fastest Edge Race time or highest Crazy Courier score.
- View Map - scroll through the mini-map to see how the map is laid out. Also allows you to change the seed.
