Charge Turn Battle (CTB) System (Final Fantasy X / Tactics style)

[MobiusXVI]

Hello ! your script it's working like a charm, i am really happy with this combat sytsem, is there a way to make it compatible with this script ? https://forum.chaos-project.com/index.php/topic,12640.0.html

I took a look at that script, and I think I can make a patch to make them compatible (if XP was more like Ace, they probably would've been compatible out of the box). If I have time this weekend, I'll make it and let you know.

i watched the video, and it look like the Persona 3/4/5 turn battle mechanic.
you know where in Persona 3/4/5 when its your turn, you take an action IMMEDIATELY.
and after you took an action, the next battler does an action when its their turn.
and when a battler has the highest Agility Stat (A.K.A. Speed Stat)
that certain battler goes first at Turn 0/1.

I've never played the Persona games so I'll have to take your word for it lol

@MobiusXVI
its ok, its just that in the Persona 3/4/5 Turn Battle Mechanic
where you strike an enemy's weakness (or land a critical hit),
they get knocked down (not dead) and you get a "1 More",
but you can't get that "1 More" again
when the enemy is ALREADY knocked down.
(and also the same "1 More" mechanic applies to the enemies as well.)

@Fred_than_dead I think this will work for you. I haven't tested it though so let me know if you encounter any bugs.

@MobiusXVI I tested it out a bit and it seems to work perfectly, thank you so mutch dude !

Hello! I've just seen this. First of all I want to thank you, it works brilliantly.

I'm trying to make a few adjustments to a game using this battle system and I have a quick question.

Is there a more optimal way of using the SKILL_SPEED_FACTORS (or any of the specific ones) when I have multiple SKILLS that have the same CT? I was thinking of something like {[1,2,3] => 10} instead of setting it individually like {1 => 10, 2 => 10, 3 => 10}.

Thanks again!

Yea, since this is ultimately just more Ruby code we can use a little bit of coding to do something like that. So for your example, you could do:

Spoiler

# SKILL_SPEED_FACTORS is identical in set up to WEAPON_SPEED_FACTORS but for skills.
SKILL_SPEED_FACTORS = {}
SKILL_SPEED_FACTORS.default = 0
# New section to add multiple skills at once
for skill_id in [1,2,3] # Here you can put all the skill IDs that have the same speed
    SKILL_SPEED_FACTORS[skill_id] = 10 # Here you can put what that same speed is
end

 

[nerthul11]

That's a good workaround, works perfectly. Thanks!

Honestly, this is why I do case statements for my configurations, especially when it comes to numbers.

case skill_id
when 1 then 10
when 2,5,10 then 20
when 20..50 then 50
else
  30
end

 

[MobiusXVI]

Honestly, this is why I do case statements for my configurations, especially when it comes to numbers.

It's an interesting idea, but I tend to view my configs as data rather than code hence why I use a hash (which is used to store data) rather than a case statement (which is used for coding logic). I will say one advantage to the hash is that it's easier to manipulate at runtime, meaning that you could take in configs from an end-user via hash and do some post-processing on the entered values, which is something I've had to do before.

 

[KK20]

I'm not saying case statements work all the time; I'm just saying in this particular instance it works better. It's also easier for people who don't know a lick of programming to config because it reads in English.

Hashes are bulky and slow, which is why I tend to avoid their use whenever I can. You'll have to tell me when you had to do post-processing though--sounds extremely niche.

 

[MobiusXVI]

Well, you might be surprised by Ruby hashes. In general, their lookup times are actually quite a bit faster than arrays especially when you're doing lookups by the key (see: Hashes vs Array). Basically, they do a sort of internal indexing in order to speed up retrieval. This makes them slower to add new elements, so you wouldn't want to use them for anything where you're constantly adding and removing elements, but for mostly static retrieval they offer excellent performance.

As for the post-processing, it really wasn't that odd. For my quest journal script, I take in a large amount of text for the quests. Because the text isn't formatted to fit neatly within the display box, I do line length calculations in order to split the text into appropriate line lengths. It's a slow operation, so I only do it once (the first time the configs are loaded) and then store the result for later display, which makes it much faster to open and display the journal while the player is actually playing.
