Been having some fun with scripting and a have a question.

I was having some fun messing with the default battle system and toying with an idea I would like to try but I think I have to ask for some advice.

1. Real time combat instead of turn based ( Any character or enemy can take a "turn" at will)
   
2. TP increases over time much like an ATB meter would based on that characters agility.
   
3. The ability to select what party member you want to do something at any time in any order.
   

What would be a good way to go about setting up such a script? Or where would be a good place to find information on something like this?

edit:

I have been tinkering around with this and seem to have it a little less than halfway completed. I currently have it setup so all party actions are no longer tied to the old turn based system.

I am currently attempting to figure out how to setup a looping function that runs in the background during the battle. All it needs to do is increase everyone's tp over time. Ill make it so mobs attack based on a timer

Then I just need to figure out how to have the ability to select any party member I want. Example

class Window_PartyCommand < Window_Command

#--------------------------------------------------------------------------

# * Create Command List

#--------------------------------------------------------------------------

def make_command_list

add_command(Vocab::fight, :fight)

end

end

^ Should be like this

class Window_PartyCommand < Window_Command

#--------------------------------------------------------------------------

# * Create Command List

#--------------------------------------------------------------------------

def make_command_list

add_command(Party member 1)

add_command(Party member 2)

add_command(Party member 3)

add_command(Party member 4)

end

end

Once that's in place I think ill have something to actually play with for a bit. Anyone have advice?
