# make_variant.sh ConstantSpinner_s3 3 5 /tmp/tr_spinners

# make_variant.sh ConstantSpinner_s6 6 5 /tmp/tr_spinners

# The variant dir is a normal Tank Royale bot directory named <NAME>: the runner
|
|
# matches the connecting bot's identity against <OUTDIR>/<NAME>/<NAME>.json, so
|
|
# the launcher exports BOT_JSON to make the binary handshake under <NAME>.
|
|
#
|
|
# The single committed ConstantSpinner binary is reused (no per-variant build);
|
|
# only SPIN_TURN_RATE / SPIN_SPEED differ.
