Venom

Can be deliberatly fired by storing -3 into .shoot. Similar to .poison it targets the memory location stored into .vloc. Unlike .poison though it can set that location to a particular value with the use of .venval. The length of time it remains that value again depends on the amount of venom that has been stored into .strvenom.

.venval inc
.backshot .vloc store
stop

cond

stop

Here's a basic example showing a bot making venom and poison as necessary. It poisons shoot keeping attackers from feeding. If it sees an enemy not a veggie it'll attack it's shooting ability making it fire backwards.

With some additional coding it could then feed from an enemy once it knows a venom shot has been fired.
