[solved] How can I condense this script?

[shintashi]

this is my repetitive script. It slows down the processing.

I tried a for loop but it crashed because of "a" when I tried

Code Select Expand

a[i] = $game_actors[b].skills[i]...

Arrays.

[modern algebra]

Yeah, use an array. I'm finding a lot of your choices kind of odd by the way. First off, $data_system.party_members[0] will get you the first actor at the start of the game. If you want to get the current first member, you need to go through $game_party. Another thing is why check 20 exactly? Why not just grab the skills the actor actually has? Also, why take the name of skill 99 if the actor doesn't have one? What's with the global variables? Maybe you could explain those choices, because I cannot see why you are doing them.

Anyway, to grab all the skills of the lead actor in the party, you can just do the following:

Code Select Expand


b = []
for skill in $game_party.actors[0].skills
  b.push (skill.name)
end

(If you really do only want the skills of the lead actor at the start of the game, then you can use the $data_system method you have in your code)

If you need to have this array have 20 entries you can add the following lines right after it:

Code Select Expand


sn = $data_skills[99].name
while b.size < 20
  b.push (sn)
end


That will make it so that you now have an array, named b, which has all the names of the actor's skills, and if that is less than 20, then it fills it up to 20 by repeating the name of skill 99.

You can access them by b[0], b[1], ..., b[19]

And again, I have no clue why you're using global variables, but if you need to put it in a global variable, then you should just use 1 and make it an array as well.

when i try your method I immediately get an error reading

"undefined method 'name' for 19:Fixnum"

Answering your questions might help. I'm attempting to make a skill editor and this is part of the "display current skills" section. Although I can edit skills using event options like text, input, and script, i'm trying to make those same options available in a more cleaned up version using Windows.

The basic function is edit existing skills. That is supposed to "load" an existing skill from the character's skill list into a display window for editing. Since I couldn't get a "for loop" to work I decided 20 skills was an unlikely high ceiling.

here's the basic flow:

1. access Journal (right now I'm using an event to trigger it but that will change later)
2. selectable menu, including Edit option
3. Edit opens up selectable skill list (I'd prefer the character list pop up first, then skill list, but don't know how to do that yet). Selecting a Skill (like Fireball) opens up Edit Menu
4. Edit menu displays a bunch of options and costs. I figure this would work like shops.

'journal' is my main set of windows, character's skill list should be a separate window.

I recognize this is a monstrous undertaking and have been working on it for a couple of months now. I would rather ask how to do something than have someone do it for me, if that makes sense.

I haven't scripted in RMXP for two years, so I made a mistake as to what the skills method returns. In RMVX, it returns the data objects. Sorry; I should have known just from reading your script that it returns IDs in RMXP. Anyway, it's the same thing as before but you just grab the data object, so:

Code Select Expand


b = []
for skill_id in $game_party.actors[0].skills
  b.push ($data_skills[skill_id].name)
end


That will make it so b contains the names of all of the actor's skills. It doesn't sound like you need the ceiling so you can probably exclude the second piece of code I had given, but if you did need it you wouldn't need to change anything from what I said above.

Anyway, good luck on your project. You probably should have started off a little more modestly and learned about loops and arrays first, but it sounds like you've put a lot of work into it and I am sure it will turn out fine.

The best help I can give you is tell you to read the Help file - it's quite comprehensive and will help you immeasurably.

This is a quicker, easier way:

Code Select Expand

b = $game_party.actors[0].skills.collect {|id| $data_skills[id].name }
