Gnarler Water-Shyness

The following code is in the Gnarler timer script, which helps keep the Gnarler out of the Ettin Desert's pond by using the water CA. It isn't held in a subroutine.

**keep away from bodies of water *Do this if you're in a room. doif room targ ne -1 *Do this if you smell any water at all. doif prop room targ 5 ge 0.00001 *Look for the room next to this one that smells less like water. setv va00 lorp room targ 5 0 *Go towards the centre of the room that smells less like water. setv va01 torx va00 *If the less-smelly room is on your left and you were going right, turn around. doif va01 lt 0 and ov10 gt 0 negv ov10 *or else, if the less-smelly room is on your right and you were going left, turn around. elif va01 gt 0 and ov10 lt 0 negv ov10 *end the turning around doif endi *end the 'smelling water' doif endi *end the 'I'm in a room' doif endi

AquaShee's Crabs use a reversed version of this to help them seek out water sources.
