By game,s installation folder,do you mean Vessel Tactic(containted everything in it) or Vessel_Tactic-Data?or Vessel Tactic.zip?

As a person that luckily can read Unity c# language,python,javascript and html language.   I do not understand the meaning in the class.cs or skill.cs.

I see you have public some insteresting categories,and in the later these categories added many different attributes,such as "movement = Movement;",I have no idea why you do this but i know how it works.

also i have no idea what does Rarity do.

as for skill.cs,i can see this is some sort of skill numbers? but i dont understand what they actually do.

So from what I can understand,Do if i want to add another new skill that has new skill effect(such as launch missile which produce shockwave pushing enemies away from the center explosion area),I HAVE to edit both skill.cs and skilllist.cs.

But IF i only added a new character that can transport allies as i mentioned before,the only thing i need to change,is add a new skill in skillist,due to carrier is a skill that already existed, and change stuffs in mods file,Ain,t I right?

now i am confused about how do i insert the new skill in the modded unit?

Sorry then, I've no idea how to help in that regard. I use the Aon mod for inserting skills, so I don't know what you'd need to do to fix it. I can still explain a bit more of what I've learned about making the skills themselves though, so that it's easier for you to start.

The code for individual skills can be found in the SkillList file. When creating a skill, most of the time this is the only place you need to go.

Each skill is broken into three pieces: 
1.) The skill ID, name and description at the top
2.) The flags which will tell the game what kind of skill it is and when to use it.
3.) The actual code which the skill preforms, if any.

Skill flags are pretty intuitive when you study where each one is used, but using the wrong flags when creating a skill will usually leave it non-functional.

To demonstrate, skills generally follow this structure:

SkillList.skills.Add(new Skill( [Skill ID], "The Skill's Name ", "Reference Name", "Description of the skill.", new Skill.Flag[]   
      {
         Skill.Flag.TurnEnd,   (When the skill will activate. If nothing is referenced it will be active all the time.)
         Skill.Flag.Trait,    (What "type" of skill it is, whether that be a buff, trait, modifier, or something else. Multiple can apply.)
         Skill.Flag.Visible        (Determines whether you can see the skill from the character's status or not.)
     }, delegate()
      {
        (Everything the skill actually does goes here.)
         SkillList.current.Pause(false);        (I am uncertain as to exactly what this line does or where it should be used, but
                                                                                      I know that  certain passive skills will cause the character to freeze without it.)

     }));

Here is a relatively simple skill as a real example:

SkillList.skills.Add(new Skill(1001, "Sleeping Beauty", "SleepingBeauty", "Digest period decreases by one additional turn each round while asleep. Uses Hibernate instead of Digest when Overburdened.", new Skill.Flag[]
        {
            Skill.Flag.TurnEnd,
            Skill.Flag.Trait,
            Skill.Flag.Visible
        }, delegate()
        {
            if (SkillList.current.skills.Contains(200) && SkillList.current.containPeriod > 1f)
            {
                SkillList.current.containPeriod -= 1f;
            }
            SkillList.current.Pause(false);
        }));

This is the skill "Sleeping Beauty", which is what Dusk Lamia uses to increase her digestion speed while asleep.
As you can see, the skill ID is 1001; this is how the skill is identified when it is referenced in another part of the code.

The skill uses the flags "TurnEnd", "Trait", and "Visible". TurnEnd means that the code is executed at the end of that characters turn. Trait means that it will be called a trait in the status page. Visible means that you can see it in that character's status

Now, to focus on the active part of the code.

if (SkillList.current.skills.Contains(200) && SkillList.current.containPeriod > 1f)
            {
                SkillList.current.containPeriod -= 1f;
            }
SkillList.current.Pause(false);

"SkillList.current" is how the game referrers to the character a skill belongs to. In this case, that would be Dusk Lamia.

"SkillList.current.skills.Contains(200)" is checking whether Dusk Lamia has the skill with the ID "200". In this case, that would be the "Sleeping" status.

"SkillList.current.containPeriod > 1f" is checking on the amount of time left Dusk Lamia needs to digest her prey. In this case, it is determining whether that period is more that one.

"SkillList.current.containPeriod -= 1f;" is taking that period, and removing one from it. If there were 6 turns until digestion before, it would now be 5.

Altogether, what this does is first check that Dusk Lamia is both Asleep, and has more than just a single turn until digestion. If that is true, it will subtract an extra turn from that amount. This is why she digests things at twice the speed while asleep.

I am not nearly as confident on how attacks work, but the framework isn't too different from skills. There are values which determine the statistics of the attack, flags to identify it, code to be executed, and restrictions as to when and how it can be used. Sorry that I can't give much information, but I'm still learning them myself.  Attacks can be found in the AttackList file.

When developing both skills and attacks, an incredibly helpful thing to do is start by modifying an existing skill which is similar to what you want to make. This way, it becomes much easier to understand how that type of skill works, and how you will need to modify it. 

If any of this turns out to be incorrect in some way, I apologize. All of this information is only what I've managed to piece together, but if there's anything specific about them you need to know I'll try my best to help.

After breifly read your reply.

I seems to start understanding why you have slow update progress,coding is soooooooo hard,I thank you for creating this "fun" game.

Anyway,in conclusion,use this code in Classlist.cs for example.

list.Add(new Class("Humvee", "Vehicle", "c911", "Vroom!Vroom! Open up for your Freedom delivery is here!", "Commander", "Master", 0, 69, new Stat(500f, 600f, Dice(15, 50f)), new Stat(140f, 200f, Dice()), new Stat(100f, 140f, Dice(5, 50f)), new Stat(70f, 100f, Dice(5, 50f)), new Stat(40f, 80f, Dice(3, 30f)), new Stat(45f, 90f, Dice(3, 50f)), new Stat(40f, 80f, Dice(3, 30f)), new Stat(100f, 120f, Dice(3, 30f)), 7, UnitInfo.Move.Ground, 30, 200, 1, 150, 5, 0, 2, (SpecialV s) => 2, 1, 5, 1, 90, 0, new int[3] { 15, 16}, new int[6] { -99, 10, 11, 16, 120, 121 }));

1.In order to add a "skill" in the modded character, I simple put new attack id from attacklist.cs in the "new int[3] { 15, 16 }" ,new skill/ability  from skilllist.cs in the "new int[6] { -99, 10, 11, 16, 120, 121 }))"?

2.Does game will treat it like two different character despite one is in mod file and the other one exist in classlist.cs and having the exact same values?

3.Ignore the "urrent.skills.Remove(122)" due to its mainly about digestion prey.

4. ignore -99 in "new int[6] { -99, 25, 26, 27, 28, 29 }" its goofy ahh stomach sizer system which i dont wanna understand due to its complexity

5.I found that skill 28 and 29 basically is the worse verison of skill 120 (, "Transporting", "Transporting", "Carrying allied units without digesting them. If an enemy is eaten, if digestion is commanded, or if afflicted with certain status effects, will digest all units inside her.")

i guess i will replace those with skill 120 and 121,due to you can have snacks in the car,with normal digestion speed and the fact how many you are carried wont really affect the speed of car(if  you didnt put 10 people in the humvee in once ofc).

6.The situation now is that,i already have finished modded unit in the mod files,and it function normally aka can only attack and vore.now i dont know how to apply/insert new attacks and skills on this modded character named "Humvee" after putting a large code(code from above in classlist.cs.Does it counted as finished and it will function normally in theory?

7.Damn,I hope my 'c911' code wont broke the game.

8.Zamn,I dont know what my "0,69" would do in ""Commander", "Master", 0, 69, new Stat"   I guess its just rarity value.

9.About Making a new Attack called "Launch Missile",In order to achieve it and attach it on the modded unit,I should go to attacklist.cs,make a new attack and let the modded unit conculde the attack id?

so uh,i copy paste c110 folder,and rename it to foxgirl,then replace images with Vstate....etc. and change the name in class.txt.

i guess its because my image is too big.
