If you’re in zone 2 and placing him offscreen in zone 2 as well as having him enter that zone, you can do this:
#From the left:
@CHARACTER spot 0.840 -100 215 in zone 2
@CHARACTER walks to spot 0.840 55 215 in zone 2 AND CHARACTER does it while walk_exhausted_loop
#From the right:
@CHARACTER spot 0.840 420 215 in zone 2
@CHARACTER walks to spot 0.840 55 215 in zone 2 AND CHARACTER does it while walk_exhausted_loop
#(in zone 2) and the combos you can do are pretty neat like adding a layer and a time to the character walking. If you’re in zone 2, you don’t need to mention the zone number. That only applies to overlays which default to the first zone if no zone number mentioned. Also, in regards to zooms, the number in each zone would be different (higher number to the right, lowe number to the left, like a graph, an example here).
