Best way to follow multiple sprites?

[Matt Slaybaugh]

Imagine a squirrel, who follows acorns when they are in line-of-sight:

[ Squirrel | ... | Acorn ] -> [ > Squirrel | ... |  Acorn ]

This works fine, but what about when there are two or more acorns on the screen, both in line-of-sight at the same time?

The code works, but this error displays:

got caught looping lots in a rule group :O

Do I need to worry about this?

(the situation is not ideal because the player can not always anticipate which way the squirrel will go, but may main concern is the infinite loop)

[Alan Hazelden]

This rule should solve that problem:

[ stationary Squirrel | ... | Acorn ] -> [ > Squirrel | ... |  Acorn ]

It's looping because every time you apply the rule to one acorn, the rule can still apply to the other too. If it has to find a non-moving squirrel, the rule can only be applied once per squirrel per turn.

Oh, thanks. I should have realized that.

And it wasn't clear to me from the documentation, but is there a rule for which direction takes precedence? Is it always above, then left, then right, then below?

>is there a rule for which direction takes precedence? Is it always above, then left, then right, then below?

you can't rely on the internal ordering/precedence (though you can view it with verbose_logging (cf http://www.puzzlescript.net/documentation/prelude.html )  ). if it's super important to you, you should rewrite them all on separate lines as separate rules.

I thought it checked them in the order of up-down-left-right?
