Trapped in a dark area in Space (yes, I know, that's just how Space is, you get the point), constantly being attacked by hostile ... stuff, how long will you survive (no, you can't just escape, yes, I know it's Space but ... good grief, just let me put in the question mark and finish)?
Okay, sorry.
Survivator is a simple arcade game made for the BornHack 2022 Game On Badge using a micro:bit to get tilting control and for saving high scores (because the CircuitPython system on the badge has a read-only file system).
The code was written on a micro:bit V2 and the CircuitPython version preloaded on the badge. I suppose micro:bit V1 will also work. The following steps should get the game running:
- Connect the following pins with wire:
| micro:bit | badge |
|---|---|
1 |
RX2 |
2 |
TX2 |
3V |
VCC |
-
Use standoffs and screws to mount the micro:bit onto the badge, connecting
GNDon both devices and micro:bit pin0to badge pinA2. The latter will be unused technically, but the micro:bit will fit nicely and the angle will be right for what is assumed in the code. -
Use python.microbit.org to flash
microbit-controller.pyonto the micro:bit. -
Copy the contents of the
badgefolder to the badge.
Here's a picture giving an impression of my assembly of the hardware:
The aim is to survive as long as possible. The screen will display the current high score and time.
With a gradually decreasing interval you will be attacked by three types of enemies, each having a different way to be handled:
- Tilt the device to dodge the green beam!
- Use button A on the micro:bit to fire your energy field at the right time when attacked by the evil but nice looking smiley rocket!
- Use the four badge buttons to activate your water shields and tilt to push the wall of fire out of the area!
Weapon and shields are only active for a limited time and must recharge for some hundred milliseconds before being available again, so you can't just win by clicking constantly.
When you're dead, use button B on the micro:bit to restart.
