For some reason, I forgot how to solve this problem

USE THIS :

@RIVERA walks to spot 0.561 86 343 in zone 3 in 0.6 AND RIVERA does it while read_phone_sad_loop AND overlay HALF_ROOM shifts to 29 157 in zone 3 in 0.5 AND BINX walks to spot 0.537 146 340 in zone 3 in 0.6 AND BINX faces right AND BINX does it while listen_phone_happy_loop THEN RIVERA starts read_phone_sad_loop AND BINX starts listen_phone_happy_loop
