adding new skills [RMXP/Scripting]

[Blizzy]

ever wanted to make new skills?
like fishing, cooking, etc.
in this toturial, we do fishing.
*the complete script is at the end of the toturial,
but be sure to follow the toturial.*

first, go into the script editor,
and go to the script: Game_Actor.
you'll see attr_reader :level, exp, skills, and some more.
(attr stands for attribute)
attr_reader means it's defined in rmxp itself,
in the database.
now, we are going to add 3 attr_accessors.
with attr_accessor, you can do:
$game_party.actors[ID].fishing_level
now, underneath attr_reader :skills, add 3 new accessors:

attr_accessor :fishing_level
attr_accessor :fishing_exp
attr_accessor :fishing_next_exp

now this is done, let's go on to the next step.
we now need to initialize the level, exp and next_exp.
(give it a value)
scroll down, and look for the line:

@int_plus = 0

beneath it. add:

@fishing_level = 1 #standard level
@fishing_exp = 0 #current exp (which starts at 0)
@fishing_next_exp = 25 #the exp needed for next level.

if you have this done, let's move on :P

now we need to make a formula to level up.
scroll a bit down, and look for:

  def id
    return @actor_id
  end

above it, bewteen "def id" & "end", add the following.

 def fishing_level
   if @fishing_exp >= @fishing_next_exp
     @fishing_next_exp = (@fishing_exp + 65)
     return @fishing_level += 1
   end
 end

i'll explain what this will do.

line 1, is the method,
which has the name of the attr_accessor :fishing_level
line 2, is an if-statement.
this takes care for leveling up.
when @fishing_exp (the current exp) is equal to
@fishing_next_exp (exp needed for next level),
something will happen(in this case: at line 3 & 4)
line 3, increase the number of @fishing_next_exp,
so the number won't be the same. in this case,
it's set equal to the current fishing exp + 65.
line 4
this adds everytime that @fishing_exp is equal to @fishing_next_exp,
1 level to @fishing_level.
line 5 + 6
this ends the if statement & the method.

to test if this is true,
put the following in a call script:

$game_party.actors[0].fishing_exp += 30 #adds 30 exp
#print the current level
print "fishing level: " + 
$game_party.actors[0].fishing_level.to_s
#print the current fishing exp
print "current fishing exp: " + 
$game_party.actors[0].fishing_exp.to_s
#prints the exp needed for next level
print "fishing exp for next level: " + 
$game_party.actors[0].fishing_next_exp.to_s

to add exp, simply do:
$game_party.actors[0].fishing_exp += number
you don't need anything to do with the next exp.

this is the toturial.
i hope this is useful.

comments & questions are welcome.

here's the complete script, for the people who don't know where to put it.

What does this script do now?

 

[freakboy]

you can make your own skills with that script.
it allows you to do it with experience points(exp) like the one in the battle!

 

[Jeff_PKLight]

Very cool, -virtual-! :D It looks awesome.

Err....this did nothing, I put the whole code in the Game_Actor script but it's done nothing, I don't see a change in anything...;/

erm....because i didn't do anything with it yet.
you can only store exp, next_exp, and level with it

 

[Datriot]

Oh, okay.(too short, stupid thingy)

Hi there, does this also allow you to make the characters level higher than lvl99? If not, how do you make it higher? How do you make the battle screen like POKEMON?

I'm using rm2k/3 and its proving difficult to get the battle sprites in...

this is only for rpgmaker xp, not for rpgmaker 2003, sorry

 

[kanto123326]

I've got the script and everything, but how do you lvl up in the actual game?
sorry if youve already said this somewhere!:P
