I'm creating my first mugen character and i would like to know how to make a power charge code for the Enter key..
It's a JUS character so i want to replicate these power chargers in those JUS Style characters.

Check the power charge code in one of these JUS characters and copy it. Simple as that

1. Create a command for holding enter in cmd:

Code:

[Command]
name = "holdstart"
command = /s
time = 1

2. Add the states:

Code:

[StateDef 1000]
type = S
physics = S
moveType = I
anim = 1000
velSet = 0,0
ctrl = 0

[State 1000, PowerAdd]
type = PowerAdd
triggerAll = Power < const(data.power) && Power < PowerMax
trigger1 = !AILevel && command = "holdstart"

[State 1000, End]
type = ChangeState
trigger1 = Power >= const(data.power) || Power >= PowerMax || RoundState != 2
trigger2 = !AILevel && command != "holdstart"
value = 0
ctrl = 1

This is very basic, you should tweak it.

3. Finally, add the changestate to the cmd:

Code:

[State -1, Power Charge]
type = ChangeState
value = 1000
triggerAll = !AILevel
trigger1 = command = "holdstart"
trigger1 = RoundState = 2 && StateType != A
trigger1 = Power < const(data.Power) && Power < PowerMax
trigger1 = ctrl

Hmmm... try using parenthesis, like this:

trigger1 = !AILevel && (command = "holdstart")

Also change it in the other line too

trigger2 = !AILevel && (command != "holdstart")

Also, forgot to mention in my previous post, but you need to specify the amount of power you want to gain:

[State 1000, PowerAdd]
type = PowerAdd
triggerAll = Power < const(data.power) && Power < PowerMax
trigger1 = !AILevel && command = "holdstart"
value = 2

EDIT: oh, and about fighter factory, you don't "need" another version but is highly recommended to use FF3 or FFStudio. FF3 is the most stable, Studio can crash more often but has more features.

Can you post the whole code here so I can take a look?
With that last error message it's impossible to know what is going on.
