A question about using this script.

I have a version of the cateroillar script. In my game, at a point, yo are assigned two warriors to follow you and fight with you. I want it so that tow events with the graphics of te warriors start following you, instead of tow warriors just appearing from behind you. Here is the script:

Code: [Select]

# When true, switch control is used
# TRANSPARENT_SWITCH = true
TRANSPARENT_SWITCH = false

# ?Switch number for transparent status
# When TRANSPARENT_SWITCH is true, transparency will be activated when the switch of this number is on
TRANSPARENT_SWITCHES_INDEX = 20

# ?Maximum number of actors
# There will be support for a large number of people in a party in the future...
TRAIN_ACTOR_SIZE_MAX = 4

# Put any actor IDs who should have a "stopped animation" if in the caterpillar
# i.e. if a party member "is floating" it will look stupid if he suddenly stops
# moving in the air.

Thanks for your time and help!

If I understands your question correctly;

The way I've always done it was to understand where the team members would appear on map if they were suddenly added to the party. Caterpillar script has a invisible trail behind the player to position them; and it's easiest to make the player walk up 2 squares so that you know the two squares behind him will be those team members' position in the future.

Then, you just make the team members walk up to those positions via eventing, and add those two characters as well as deleting their events at the same time for a virtually 'seamless' team-merging.
