Spooky Maze is simple game where ghost is located in the maze. The goal is to collect 100 coins. The ghost can find artifact "Walker" which allows him to pass throght the wall for limited period of time. The ghost can use dynamite to clear wall in the vicinity. The ghost can use also Teleport spell to move to random place in the maze. The Teleport spell requires some time to recharge. There are some not friendly spirits running around the maze, when collision occurs the ghost is teleported and loses five coins which are then send randomly back to the maze.
Binaries are available in GitHub Releases.
Binaries can be flashed by:
- GUI esp-helm
- CLI espflash
espflash write-bin 0x0 spooky-maze-esp-wrover-kit.bin - Web browser (experimental) ESP-Launchpad.
Recommendation: Open only sub-directory with specific target with specific toolchain in CLion, because only one toolchain is supported for resolving code dependencies. Opening whole workspace works, just some code dependencies might not be resolved. This is also limitation of cargo, which supports only one toolchain per build.
Install espflash which is required to flash and monitor the app on Embedded Device:
cargo install espflash
cargo install cargo-espflash
Enter the directory with project and build it:
cd esp-wrover-kit
cargo build --release
The script builds all possible targets: support/ci/build-esp32-firmware.sh
Open subdirectory with target in VS Code with installed Wokwi Extension. Select Wokwi: Start Simulator.
cd wasm
npm install
npm run serve
Open in web browser: https://localhost:8443.
Note: https is required for access to accelerometer data - https://w3c.github.io/deviceorientation/#security-and-privacy . It's possible to run the app without accelerometer on http.
Each directory contains implementation specific for the HW.

Following steps are useful for IDE integration, so that IDE can recognize which is your current target and fature set.
Check target configurad in the file .cargo/config.toml.
It should be one of following values:
target = "xtensa-esp32-none-elf"
target = "xtensa-esp32s2-none-elf"
target = "xtensa-esp32s3-none-elf"
target = "riscv32imac-unknown-none-elf"
If no value is selected, make sure to specify target on command line.
Check default features in Cargo.toml. Make sure that default set contains your board and display combinations.
If no value is selected, make sure to specify features on command line.
