Known Compatibility Issues

This script is incompatible with every ABS (Sapphire, XAS, ect... ).

Author's Notes

This is actually my second attempt at a script like this, a few months ago I tried to modify the enemy parameters in Game_Battler and I kept getting an error so I quit. I just now realized that it would have also modified the actors, making the entire script completely pointless.

Restrictions

Check the header of the script.

How could this work with Yanfly's Enemy Levels and System Game Options? Maybe add an option to change levels rather than stat? Also I'd swap Hard and Heroic(at least in name, Heroic sounds way harder). Just sayin'.

System options, yes. Enemy levels, May be. I chose the names based upon halo 3 (except for hard). Either way you get to customize the name.

This script seems really good for like a Touhou game, don't you think?

I've never played one, so may be. 

Just looked through a bit of your code, and while I do say that there's nothing wrong with what you've done, there are more efficient and safer ways for what you've done. Mainly, the core adjustment made with this script, the Game_Enemy#param_base method you overwrote. You may have thought about how to alias this method, and there's nothing wrong with not seeing it; it's not as clear as most methods are.

Code: [Select]

class Game_Enemy < Game_Battler
  alias todd_difficulty_gmen_param_base param_base
  def param_base(param_id, *args)
  n1 = todd_difficulty_gmen_param_base(param_id, *args)
  n2 = case $difficulty
  when 0 then TODDDIFFICULTY::EASYM
  when 1 then 1
  when 2 then TODDDIFFICULTY::HEROICM
  when 3 then TODDDIFFICULTY::HARDM
  end
  return n1 * n2
 end
end

Would be the way I'd do it. There's nothing necessarily wrong with the way you've done it, I'm simply paranoid about overwriting methods.

I also noticed there's no way to call the scene... Unless I'm missing something?

You can call the scene with Scene_Difficulty.new in a script call, and there is also an option to include it in the main menu.

@Pacman Alright I'll check to make sure there's a safer way next time.

@Wiimeiser What Pacman said, I'll update the topic to include it.

Seems like a good idea

I've got suggestion to allow changing the battle theme depending on which difficulty is selected
Of course that's only if the creator actually wants to allow the battle theme to be changed.

I can probably add that feature today. 

I may do it tomorrow, I tried it today and this happened. 

Whoa, that's no good

I don't work with VXA, is it the same method when changing the battle theme?



Actually this reminds me of someone at my Uni who constantly manages to crash visual studio, not memory leaks, but actually breaks the program.
It's become a usual thing to blame him whenever something goes wrong on anyone's game

What maker do you use?

lol 

I forgot about working on this, I'll try to release the new version this week.

I still haven't done the battle themes yet, I've been busy. I don't know when I can get to it, sorry. Any way this script is incompatible with every ABS (Sapphire, XAS, ect... ). You can run the game but you will not be able to load.

I like KGC's difficulty script better, too bad someone doesn't convert it to Ace.

When I use the the script call Scene_Difficulty.new, it doesn't call the screen up. I know you can have it in the menu (which I plan to) but I want to make it so you choose at the very beginning and the screen won't come up. Can anyone help me with this?

Code: [Select]

SceneManager.call(Scene_Difficulty)

Thank you!

Unfortunatly, I seem to have run into another problem. Let's say I pick a difficulty (it doesn't matter in this case) and I walk around, get into fights and it works fine. I save and then load the fine, get into a fight and again, it works fine. But when I completely close the game, load a file and go into a battle, the game crashes. I know why it crashes. The error is the error when a difficulty has not been chosen which leads to me to the question for this script to work, does the difficulty have to be chosen every time the game is opened? I can't seem to find a solution to this (it crashes every time) so if you could help me out I would really appreciate it.
Thank you

I managed to recreate the problem, I'll try to fix it tomorrow since I have to head to bed.

Thanks for helping with this.

Sorry I wasn't able to try and fix it today, I'm been pretty busy but I may be able to fix it this week.

No problem, take your time!

I'm sorry for making you wait so long, here's a fixed version.
Turns out all I had to do was add $difficulty = $difficulty to battle manager.
