'Always on' Passive skills

[Leon_Westbrooke]

This is a passive skill script that has the skill 'always on'.  So, let's say you want skill number 83 to add 5% to hp, this script allows it.

The instructions are in the header of the script, and screenshots, well, it is hard to show a stat being increased by a skill.

#  Passive Skills, by Leon_Westbrooke
#  v. 1.0
#----------------------------------------------------------------------
#  Instructions:  Put below all default scripts, and above Main
# 
#  Features:  Creates passive skills that adds to the stats:
#    HP, SP, STR, DEX, AGI, INT, EVA, Atk, PDef, MDef
#   
#    Adds stats based on a percentage. (so, 100% will double that stat.)
#
#  To have a skill lower stats, make the number negative in the module.
#
#  Compatability:
#    There are no known clashes with other scripts.
#
#  Notes:
#    This script aliases the stats in Game_Actor, and rewrites the refresh
#    method in Window_Skill.

Nice script!

I don't like using hashes for databases myself, but I don't really have a reason to oppose it

Nice work.

[Leon_Westbrooke]

May i ask why you dont like using modules as databases?

[modern algebra]

I have nothing against modules. I said hashes as in {}. In this case, I think that you are using the hash appropriately and that they make the database more intuitive and easier to use. I just prefer to avoid hashes myself. It's purely preferential on my part.

[Zeriab]

Retrieving data from arrays are faster than retrieving data from hashes.
In this case the difference will probably be so little and finding out whether a given key is present is on average faster than with an array. That is, if you have used the proper methods.

Don't use:

Code Select Expand

if ps::Passive_Skills.keys.include?(@skills[i])
This will create an array containing the keys in the hash. On this array you check if the skill is present.
Instead you should use:

Code Select Expand

if ps::Passive_Skills.has_key?(@skills[i])  # Or whatever the correct syntax is.

Change accordingly if there are other places where you use .keys.include?(something).

I doubt the decrease in speed will be noticeable. Especially if the information is only updated when necessary. The only time that will be is the first time base_maxhp, base_maxsp, base_str and so on. The first time one of them are called after the actor learns or forgets a skill. Basically, whenever the actors skills changes.
You update the passive skills effects whenever base_maxhp is called and only when base_maxhp is called. (Also, why do you update the skills after you add @passive_skills. This could give you the wrong hp bonus one time.)
You rely on base_maxhp being called before the other methods are called. You shouldn't.
One can notice that either learn_skill or forget_skill must be called for the skills to change.
I suggest that alias both and let them call the alias as well as setting a flag telling the skills might have been changed; for example @passive_skills_update = true.
Then we could for example have a base_maxhp method looking like this:

Code Select Expand

  def base_maxhp
    ps = Passive_Skills
    if @passive_skills_update || @passive_skills_update.nil?
      passive_bonus
      @passive_skills_update = false
    end
    n = leon_passiveskills_gameactor_basehp
    n = n + (n * @passive_hp * 0.01)
    return n
  end

And have similar changes to the other base methods.
Note the code I have written here has not been tested. So don't be surprised if you encounter errors, be critical

You have made accessor for the passive_hp, passive... and so on (attr_accessor :passive_hp)
Why have you made them as accessors and not as readers? (attr_reader :passive_hp)
Changes to the passive values will just be overwritten next time a passive skill is learned or forgotten.

I suggest you test how it works with old saves

All this time I have focused on the problems. I hope you did not get discourage. I wanted to help you make the script better.
It is a nice script as modern said. There were just some inefficiencies in it. Another question is what did you do right. What was good?
It would be unfortunate if you removed or changed a good feature into something worse during the effort of making it even better.
I like how you showed which parts was added to the Window_Skill so it should be relatively easy for the users to add the changes themselves
I like the idea. Good job coming up with it
The way you aliased the base_ methods in Game_Actor. Should increase compatibility with other scripts.

I'll look forward to your revision.

*hugs*

[Leon_Westbrooke]

I see where you are coming from, Zeriab. Thanks for the tips, too. I wrote this forever ago (seriously, like... last march) so my scripting in it is rustly.  At any rate, I do appreciate the advice.

[themrmystery]

Okay... beginner question:

How do you setup multiple passive skills?

This works, for say skill_id = 1

Code Select Expand

  Passive_Skills = {
  1 => {'sp' => 100}
  }
end

However, I've tried all three of the following methods, and either get a syntax error, or it only places the first/last passive skill:

Only gives SP bonus:

Code Select Expand

  Passive_Skills = {
  1 => {'sp' => 100}
  }
  {
  2 => {'hp' => 100}
  }
end

Syntax Error:

Code Select Expand

  Passive_Skills = {
  1 => {'sp' => 100}
  2 => {'hp' => 100}
  }
end

Only gives HP Bonus:

Code Select Expand

  Passive_Skills = {
  1 => {'sp' => 100}
  }
Passive_Skills = {
  2 => {'hp' => 100}
  }
end

What am I doing wrong?

[modern algebra]

You almost have it right with #2, but you are missing the comma:

Code Select Expand


  Passive_Skills = {
  1 => {'sp' => 100},
  2 => {'hp' => 100}
  }
end


should work. Though, I might be missing something.

[themrmystery]

Deleted Original Message:

Yes, thank you, silly comma caused me all this trouble! =)

[themrmystery]

If anyone else needs to know more information about using this script here's a code snippet for getting multiple increases to one skill:

Code Select Expand

  Passive_Skills = {
  4 => {'sp' => 100, 'hp' => 100}
  }
end

[shintashi]

I tried this system with my game and it just made all my skills disappear. Of course I'm using some custom stats and Mo's ABS, which might be interfering with skill programs.
