.tiejoined = 0 if what focuseye is seeing isn't joined via a tie, and will = 1 if what focuseye is seeing is joined via a tie, I could imagine it useful for not killing the veggies of your colony.
.tmaxlen will be set and specifys the maximum length for a tie, and .tminlen will specify the minimum length for a tie.
Brilliant hey? Will make multibots that much better
