DBZ_PassiveSkill v1.0
by dividedbyzero

Introduction
I created this script simply because I'm not smart enough to comprehend KGC_PassiveSkill and I wanted passive skills to be compatible with my SkillLevel script. For those unfamiliar with passive skills, it allows you to implement bonuses on skills such as parameter increases and special actor and equipment options. When paired with my script "DBZ_SkillLevel", this script has extra functionality like curves and skill level requirements.

Features
- Enables parameter increase when a skill is learned.
- Enables skills to grant special abilities such as dual attack.
- Allows parameter increase curves when combined with DBZ_SkillLevel.
- Allows ability skill level requirements when combined with DBZ_SkillLevel.

How to Use
Simply edit the note tag of a skill to include any supported tags.

PARAMETER TAG:
<param (+/-)number[%][ curve (+/-)number[%]]>
This modifies "param" to either add or subtract "number".
e.g. <atk +10>

If a percent sign is appended to the number, it will be set to that percentage of the parameter's total.
e.g. <maxhp -10%>

If you also have my script, "DBZ_SkillLevel", you may use the second section of the parameter tag. It follows the same syntax as the first.
e.g. <cri +10 curve +5>

Accepted parameters include the following:
maxhp, maxmp, atk, def, spi, agi, hit, eva, cri, and odds.

EXTRA TAG:
<extra extra_function[ at level]>
This has different effects depending on "extra function".

<extra two_swords_style>
Would enable dual-wielding weapons.

Once again, if you have "DBZ_SkillLevel", an extra feature is unlocked: skill level requirement.

<extra dual_attack at 10>
Would enable dual attack at skill level 10.

Accepted functions are as follows:
- two_swords_style: Enables wielding of two weapons.
- fix_equipment: Locks equipment. Not sure why you'd use this.
- super_guard: Defending becomes twice as effective.
- pharmacology: Doubles recovery effects from items.
- fast_attack: Always attacks at beginning of turn.
- dual_attack: Attacks twice.
- prevent_critical: Prevents critical hits against actor.
- half_mp_cost: Halves MP cost of everything.
- double_exp_gain: Doubles EXP gain.

Awesome, thanks.
I was looking for something like this, it works great on the Skill Tree I use.

[Kurisu-San]

omg thank you so much I was actually about to post a script request asking for someone to edit the passives so that it required a certain level to reach so the skill would unlock, thank you so much ^^

*delves into the script to start making edits*


EDIT:

Hey I was wondering what I would do to say use an ability such as.... Asuran Punch which is an 8 hit attack? Would I have to add another paramater inside your script to do so?

[roachman07]

hello this looks great
but is they anyway i can make it add more attacks per lvl like 2 attacks at lvl 5 and than attack 3 times at lvl 7
something like that

and is they a way i can make the number of attacks random

[zanaram]

This is an awesome script, i was pumped to use it in my game when i found it. But I'm having a problem with it. I have an event that grants you the passive skill for dual weapons, but then when i go to check out my skills to see if it's there a message pops up saying...

Script 'Passive Skill' line 121: NoMethodError orrurred.
undefined method 'skill_level' for #<Game_Actor:0x396df60>

I havn't played with this script since it doesn't seem to need any configuration and cause I don't know anything about scripting. Anyway, can anyone help me out with this error? please
