Remove all skill levels and xp boosts

[Colin]

I'd like to reset character skill levels and xp through lua. I have found the function LoseLevel, but this would require lots of checking current level and various other wasteful calls. Is it possible to do a full reset of skill levels? Or will I need to build a custom function to run through all skills.

Temporarily I have written the following function to perform more or less what I want.

 

--//
--// Clear all skills and xp

--// 
local function clearSkillLevels(player)
    local pl = PerkFactory.PerkList;
    local xp = player:getXp();
    
    for i = 0, pl:size()-1 do
        local info = pl:get(i);
        local pk = info:getType();        
        local curLevel = player:getPerkLevel(pk);
        
        if curLevel > 0 then
            for i = curLevel, 0, -1 do
                player:LoseLevel(pk);
            end;
        end;
        
        xp:setXPToLevel(pk, player:getPerkLevel(pk));
    end;
end;

 

If there is no better way, then if someone can point me in right direction to also clear xp boosts for each skill. Thanks.

spoiler bbcode ruins code formatting

Maybe try:  setPerkLevelDebug(PerkFactory.Perk perk, int int1)

I don't know if it works, but its name suggests it will do what you want.

There's also: player:level0(PerkFactory.Perk perk)

Great, level0 is ideal

        if curLevel > 0 then
            player:level0(pk);
        end;

 

However, it still does not clear the xp boosts, the api docs don't have much info filled unfortunately.... Once I get home later tonight I will check through all the apis for what I need. Thanks.

CharacterSave mod does it.

Beware it is easy to confuse XpBoost and XpMultiplier.

The first is related to profession and traits.

--remove all previous profession, traits [..] (incldues XpBoost removal)
character:getDescriptor():setProfession("unemployed");
character:getTraits():clear();

--alternative selective XpBoost removal (not tested)
character:getXp():setPerkBoost(perk, 0)

 

The second is related to skill books.

--add
player:getXp():addXpMultiplier(perk, multiplier, levelMin, levelMax);

--remove
player:getXp():getMultiplierMap():remove(perk)

--alternative remove functional equivalent with current vanilla state (not tested)
player:getXp():addXpMultiplier(perk, 1, levelMin, levelMax);
