Skill leveling up Script (Resolved)

Thank you to Winged for the help.

You could have the skills each call their own common event which +1 to a variable. Then you could put in a conditional branch on that variable, which makes the person forget that skill and learns a new one with the same name but better effects. So, have the skill call something like this:

Control Variables: [Skill Counter] + 1
Conditional Branch: Variable [Skill Counter] = 50
    Change Skills: - [1st level Skill]
    Change Skills: +[2nd level Skill]
Branch END
Conditional Branch: [Skill Counter] = 1000
    Change Skills: - [2nd level Skill]
    Change Skills: +[3rd level Skill]
Branch END
 

Thanks, but only one slight problem. If i was to do that i would need to make over 100x the skill thats improved just for one skill, i;ve already got around 100+ skills so i think a scrip may be necisary, but thank you anyway

you could make a common event with what Modern Algebra said.

Control Variables: [Skill Counter] + 1
Conditional Branch: Variable [Skill Counter] = 50
    Change Skills: - [1st level Skill]
    Change Skills: +[2nd level Skill]
Branch END
Conditional Branch: [Skill Counter] = 1000
    Change Skills: - [2nd level Skill]
    Change Skills: +[3rd level Skill]
Branch END

And when you say 100+ skills, you mean in total? If so, then that means that you only need this event for each of the beggining skills

But I think he wants to have 100 levels for each skill as well. He will run out of room in the skills database, so he needs a script which will update the skills directly, rather than swapping. It's actually a script I would like to write, but I'd need to learn the syntax for this stuff first.

Exactly.

I THINK there is already a script somewhere, I'll go looking (it was called "Skills that Level Up" or something)

~Winged

thanks winged, let me know when you got somthing. winger is also the legend.

I've come up with a kind of conclusion but it would mean that the skills would have to be harder to level.

Skill Update
Found at: http://www.k3.dion.ne.jp/~claimh/rgss/index.html
By: Claimh

What Does This Do?

• Allows skills to gain levels
• Allows skills to grow in power
• Allows skills to decrease in SP consumption
• Allows skills to change animations upon reaching new levels
• Allows the hit rate to increase
• Allows skills to have a maxium level
• Allows the ability to add and remove states
• Allows the adding of new attributes
• Some other stuff that I forgot but is commented in the script (probably)

Spoiler for Script:

#     * System to create each skill's own 'level'... Draw_skill_exp

#
#     NOTE by DERVVULFMAN:

#     for both systems to work together. If placed above both of these systems,

Spoiler for Screenshot:

In order to change the words that display the level search the script for 'Level Information Display' and edit:

Code: [Select]

name_level = skill.name + " (Level" + @actor.skill_level[skill.id].to_s + ")"

To work with Blitz Skills the order must be:
BLITZ
BLITZ Command Add-On
SKILL UPDATE
DerVVulfman's BLITZ/SKILL Patch

This is a good way of preventing attack skills gained at the beginning of the game from being useless further down the line.
Not for use in commercial games as stated by Claimh.
