!!! LeChuck random appearance algorithm Ron Gilbert posted [https://www.grumpygamer.com/speed_running_mi|the SCUMM source code] for the algorithm that controls the random appearance of LeChuck at the end of the game. %%SRC_EMBED scumm lechuck-appearance-chance is 4 lechuck-appearance-interval is 300 times-lechucks-appeared-recently += 1 foo = (3 - times-lechucks-appeared-recently) foo = (random foo) if (!foo) { ; after he's popped up a couple times he's likely to disappear for a while times-lechucks-appeared-recently = 0 lechuck-appearance-chance is 10 ; that is, 1 in 10 lechuck-appearance-interval is 500 } if (magic-doll) { ; speed him way up after you make the doll if (owner-of needle is selected-actor) { ; and have the needle lechuck-appearance-chance is 2 lechuck-appearance-interval is 120 } } %%END_EMBED Ron adds: %%QUOTE There are some other random conditions about what item you picked up last, etc, but this is the core of it. %%QUOTE_END
