Neural network

cargo r -r --features="nn"

Api server for neural network (optional)

# generate prisma db client
cargo prisma generate
# push schema to database
cargo prisma db push
# run api server
cd api && cargo r -r
# run app with saving replay buffer
cargo r -r --features="nn,nn_api"
# prisma studio https://github.com/Brendonovich/prisma-client-rust/issues/96
npx prisma studio

Key bindings

• UP, DOWN, LEFT, RIGHT - drive
• 1, 2, 3, 4, 5 - camera views
• 0 - free camera with WASDQE(SHIFT) control and mouse
• R - debug mode
• SHIFT+SPACE - respawn at random position
• N - toggle nn
• H, J, K, L - directed light control
• X - enable sound, Z - decrease volume, C - increase volume
