Modifying CO stats

This Reference Page assumes you have followed or understand the basics of Custom CO creation. In case you do not, check out that tutorial first.

This page can serve as a reference on how to modify the stats of COs during the day to day, Power and Super Power. The return values of the functions in this Reference can be conditioned with the help of the function co.getPowerMode(), which has several return values, among them:

• GameEnums.PowerMode_Tagpower
• GameEnums.PowerMode_Superpower
• GameEnums.PowerMode_Power

And a default value, which can be used to set the day to day abilities.

The following functions modify the general stats of a CO. For specific Units and Unit Types modifications, check out the info on Units and Unit Types

Common Parameters

Before we get to the functions, it's important to familiarize yourself with some of these parameters. Many of the functions use them, and most of the time they serve the same purpose. Therefore, instead of repeatedly explaining what they do every time they show up in a function, they will be explained here.

• The co parameter refers to the CO object. You will find this in practically every function here. We use this reference data related to the CO itself, such as the aforementioned co.getPowerMode() which is used to check the current state of the CO power.
• The action parameter refers to the action object. Typically found in functions called just before or after moving a unit, you can use this to grab data related to the act of moving the unit itself. For example, action.getMovePath().length returns a number corresponding to the number of spaces moved.
• The map parameter refers to the map object. It is often used to reference data related to the game map, such as map.getCurrentDay() which returns the current day count as an integer.

Offensive Bonus Modifier

This function is called when calculating how much damage the CO does in battle. In addition to being called during a battle, the game calls it just before a battle to display the estimated damage percentage.

this.getOffensiveBonus = function (co, attacker, atkPosX, atkPosY,
    defender, defPosX, defPosY, isDefender, action, luckMode, map)
{
     return 0; 
};

The function takes an integer as the return type.

Parameters

• attacker refers to the attacking unit (your unit).
• atkPosX and atkPosY refers to the attacker's position. This is the actual attacking position, not the attacker's starting position (if the attacker has moved before attacking).
• defender refers to the defending unit (the enemy).
• defPosX and defPosY refers to the defender's position.
• isDefender is a boolean. It is false if the CO started the battle, and true otherwise.
• The luckMode parameter appears to serve a technical purpose. The game uses it to calculate the maximum and minimum luck damage in order to display them before a battle (if the "detailed battle info" option is enabled in the settings). When the function is called during the actual battle, luckMode will always be equal to GameEnums.LuckDamageMode_On, so it should have no gameplay effect.

Defensive Bonus Modifier

This function is called when calculating how much defense the CO has. Like getOffensiveBonus, outside of the actual battle, the game also calls this to display the estimated damage percentage.

this.getDeffensiveBonus = function (co, attacker, atkPosX, atkPosY,
    defender, defPosX, defPosY, isAttacker, action, luckMode, map)
{
    return 0;
};

The function takes an integer as the return type.

Do not correct the typo in the function's name ("Deffensive" instead of "Defensive"), as it won't work if you do.

Parameters

• attacker refers to the attacking unit (the enemy).
• atkPosX and atkPosY refers to the attacker's position. This is the actual attacking position, not the attacker's starting position (if the attacker has moved before attacking).
• defender refers to the defending unit (your unit).
• defPosX and defPosY refers to the defender's position.
• isAttacker is a boolean. It is true if the CO started the battle, and false otherwise.
• The luckMode parameter appears to serve a technical purpose. The game uses it to calculate the maximum and minimum luck damage in order to display them before a battle (if the "detailed battle info" option is enabled in the settings). When the function is called during the actual battle, luckMode will always be equal to GameEnums.LuckDamageMode_On, so it should have no gameplay effect.

Cost Modifier
