Best-practices question about instantiating prefabs
« on: February 11, 2012, 11:11:00 AM »
I have a character manager FSM.  When a character needs added to a scene an event is sent.  It needs to know which character to add and then I need to set a few variables using script methods.  The problem that I see here is that I need to pass a parameter in some capacity.

So..  This is what I have now.

Global Variable: Character Type (String)

I first set the Character Manager variable "New Character Type".

I send the "Add Character" event to the Character Manager.

This seems clumsy.  What am I missing?

You could use Event Data instead of a global variable. Use Set Event Data to set some parameters, then the character manager FSM could use Get Event Info to get the event data. Seems a little cleaner...

EDIT: Or depending on the number of character types you have, just make an event + state for each one. Then you can also do custom setup on each character type. E.g.. A MakeSoldier state that has a global transition with a MakeSoldier event. Now just send MakeSoldier to the character manager FSM. CharacterFactoryFSM might be a better name...

The event data solution is definitely better.  The issue is that there are something like 100 character types.  That's a specific need for this design.
