I'm trying to design a quasi-skill that will be tracked via an incrementing int on a "database" item for persistency. I would like said skill to have a specific power use from say int 100-200 then switch to a slightly more powerful version from int 200-300, and grow even more powerful from 300-400, and top out at 500 where it would become permanent. This is far beyond my scripting capability any help is appreciated and cookies will be handed out.

are you looking for:

if( nSkill < 100 ){
     // skill not high enough (under 100)
} else if (nSkill < 200) {
     // specific power (100 - 200)
} else if (nSkill < 300) {
     // slightly more powerful (200 - 300)
} else if (nSkill < 400) {
     // even more powerful (300 - 400)
} else if (nSkill < 500) {
     // i guess even more powerful (400 - 500)
} else {
     // capped out at 500+
}

you could do the same with a switch statement, but i always found if / else to be a little more intuitive for the beginning programmers.

"else if" will evaluate the statement only if the previous statement is false. that way you can assume when it checks (nSkill < 200) that you're in the 100 - 200 range, since (nSkill < 100) already failed. this avoids needing the compound checks of if ( (100 < nSkill) && (nSkill < 200) ) and such.

This is what I am starting with, I was initially going to have it just 5 stages outright and hand out items according to player level, accomplishements, etc. Then I figured I would pose the question of how to make it a growing "skill" which would gain power over use and experience and eventually end in a permanent weapon enhancement. Thinking about it more today I would also want random chances of failure in lower "levels". Since this is conversation driven off the item itself, on failure it would send a message and decrement the int value so the player in essence is leveling their "skill" of sharpening.

#include "x2_inc_itemprop"

void main()
{
    object oItem;
    itemproperty ipAdd;

    // Get the PC who is in this conversation.
    object oPC = GetPCSpeaker();
    object oDatabase = GetItemPossessedBy(oPC,"Database");
    // If the local int on Database item is Equal to 100.
    if ( GetLocalInt(oDatabase, "sharpening_skill") == 100 )
    {
        // Alter the weapon equipped by the PC.
        oItem = GetItemInSlot(INVENTORY_SLOT_RIGHTHAND, oPC);
        SetPlotFlag(oItem, TRUE);
        SetStolenFlag(oItem, TRUE);
        ipAdd = ItemPropertyKeen();
        IPSafeAddItemProperty(oItem, ipAdd, 600.0);
    }
    // Else, if the local int on Database item is Equal to 200.
    else if ( GetLocalInt(oDatabase, "sharpening_skill") == 200 )
    {
        // Alter the weapon equipped by the PC.
        oItem = GetItemInSlot(INVENTORY_SLOT_RIGHTHAND, oPC);
        SetPlotFlag(oItem, TRUE);
        SetStolenFlag(oItem, TRUE);
        ipAdd = ItemPropertyKeen();
        IPSafeAddItemProperty(oItem, ipAdd, 1200.0);
    }
    // Else, if the local int on Database item is Equal to 300.
    else if ( GetLocalInt(oDatabase, "sharpening_skill") == 300 )
    {
        // Alter the weapon equipped by the PC.
        oItem = GetItemInSlot(INVENTORY_SLOT_RIGHTHAND, oPC);
        SetPlotFlag(oItem, TRUE);
        SetStolenFlag(oItem, TRUE);
        ipAdd = ItemPropertyKeen();
        IPSafeAddItemProperty(oItem, ipAdd, 1800.0);
    }
    // Else, if the local int on Database item is Equal to 400.
    else if ( GetLocalInt(oDatabase, "sharpening_skill") == 400 )
    {
        // Alter the weapon equipped by the PC.
        oItem = GetItemInSlot(INVENTORY_SLOT_RIGHTHAND, oPC);
        SetPlotFlag(oItem, TRUE);
        SetStolenFlag(oItem, TRUE);
        ipAdd = ItemPropertyKeen();
        IPSafeAddItemProperty(oItem, ipAdd, 2400.0);
    }
    // Else, if the local int on Database item is greater than 500.
    else if ( GetLocalInt(oDatabase, "sharpening_skill") > 500 )
    {
        // Alter the weapon equipped by the PC.
        oItem = GetItemInSlot(INVENTORY_SLOT_RIGHTHAND, oPC);
        SetPlotFlag(oItem, TRUE);
        SetStolenFlag(oItem, TRUE);
        ipAdd = ItemPropertyKeen();
        IPSafeAddItemProperty(oItem, ipAdd);
    }
    else
    {
    }
}

Try this.

void main()
{
    object oItem;
    itemproperty ipAdd;

    // Get the PC who is in this conversation.
    object oPC = GetPCSpeaker();
    object oDatabase = GetItemPossessedBy(oPC,"Database");

   // Get the skill on the DB item.
   int nSkill = GetLocalInt(oDatabase, "sharpening_skill");

   // Make sure the skill is greater then 0. (sanity check)
   if (nSkill)
   {

     // We at least have a skill,
     //Take care of the things that always happen at this point.
     oItem = GetItemInSlot(INVENTORY_SLOT_RIGHTHAND, oPC);
     SetPlotFlag(oItem, TRUE);
     SetStolenFlag(oItem, TRUE);
     ipAdd = ItemPropertyKeen();

     // calculate the duration
     float nDur;
     if (nSkill > 500)nDur = 0.0;
     else nDur = (nSkill / 100) * 600.0;

     // Add the property
     IPSafeAddItemProperty(oItem, ipAdd, nDur);
   }
}

Awesome!! Thank you very much, any chance of adding in a random failure if below say 250 on the int value? Or better yet a selectable chance of failure so it could be changed by whomever decided to use the script?

One potentially better way of doing it, would be to determine the
maximum strength/effect : of the power in question
ascertain the maximum skill amount: when this skill amount is acquired, you have the maximum strength/effect possible.


Then, any skill that the player has, is worked out as a percentage of the maximum possible

eg

Max Damage of the skill, (just as an example) = 700
100 points out of 500 = 20%
20% of the Maximum possible damage = 140 140 Used as a Base Damage (randomize it with some d12() additions?


But this process can easilly be adapted for Item Properties, or persistent effects on the player

eg
Maybe a Damage Reduction effect?

Max Skill = 100
Max Amount Absorbed = 30
Players Current skill = 35
35% of 30 = 10.5
Player gets 10.5 Damage Reduction effect for this skill level


It might sound rather lazy, but implimenting a flexible percentage based system, would
1. Mean you dont need to plan the different tiers
2. Every skill point counts - no need to worry about thresholds.
3. Well.... its just awesome - cause it can be turned into a framework.

Define you max effect
Define you max Skill level
Divide current Skill Level, by Max Skill level x by hundred = percentage
Then calculate the percentage value of the max effect.

This could be applied to damage immunity, damage reduction, damage shields.
Maybe even to item properties etc
