Script Title:......... PnP Style Combat
Script Version:.... 1.0, initial release
Author:................moodgiesanta

First scripting project, be gentle.

Description:
This script changes the battle system to one found in, say, D&D or d20.

Needs special weapon attack values, as Weapon ATK is radically changed to fit normal PnP procedures.

Demo showing some different style classes, some weapons to play around with, one set of armor that makes sense in the rules, and a quick and dirty way to collect statistic information from the player using events:

http://rapidshare.de/files/24877992/Project1.exe.html
Link broken, please use the script posted at the bottom along with the description directly below

I'd post screenshots but it's more of an internal script, not much to see
on the outside other than the different numbers that pop up.

Use the Battle Simulator to play around with monster attributes to get
a handle on the system, or just start importing all your PnP monsters.
The demo is an abandoned project with placeholder screens; scripting is much more fun for me so far.

Brief Explanation:

Statistics (except HP/SP) don't normally go up every level in these kind of systems;
a maximum level of 20 sounds about right. You *might* want to hand out
5 bonus points over that span.

I would use a point-based system for magic, eg a first level spell costs 10 SP, a second level spell would cost 20, and so on. If you use items that use common events to learn "skills" for mages, you can also easily limit the amount of known spells by intelligence.

Strength, for normal characters, should be between 3 - 18, with 10 as normal. Some higher level strengths are included for monsters.

Dexterity should also be in the range of 3 - 18, with some higher levels included for completeness.

Both give a +1 bonus to hit per 2 points above 10 and -1 for every two below it. Strength adds damage (but low strength does not detract), dexterity adds/lowers defense.

PDEF --> Armor Class (AC) and should probably be changed via editor to reflect that. 10 is unarmored, 20 is a well-armored knight. A shield should give 1 or 2 AC bonus.

MDEF --> Damage Reduction (DR) and should definitely be changed via editor to avoid confusion. Don't make spells reduced by MDEF because MDEF is no longer really MDEF. It follows the following pattern:
---------------------------------------
Damage Reduction Numbers and their Meanings
number equals the number on the list
+1/4 means damage reduction of four, only +1 magical weapons or better may hit
1-15 = +0/number
16-30 = +1/(number - 15)
31-45 = +2/(number - 30)
46-60 = +3/(number - 45)
61-75 = +4/(number - 60)
76-90 = +5/(number - 75)
A +2 weapon will suffer no DR against a +1 enemy or +0 enemy, a +3 weapon will not suffer against a +2, +1, or +0 enemy, and so on.
---------------------------------------
Intelligence also should probably go from 3 - 18, for consistency's sake. It is immaterial in normal battle.
Agility --> Attack Bonus and should definitely be changed via editor to reflect the change. A good guide is 1 per level for warriors, down to 1 every other level for a mage or other weak fighter.
HP should be, at the most, gained at 12 for level per a barbarian,
4 per level for a mage at the least.
Wisdom and Charisma don't really factor into battles normally and so are not modelled. Use variables to store these if you want them or script them in. This script is a battle system script not a total conversion (not yet at least).
Weapon ATK is no longer a normal numerical value but rather an indicator. See Damage Roll explanation.

To hit rolls are as so: (random number between 1 - 20) - defender's DEX bonus + attacker's STR bonus + attacker's attack bonus - defender's AC + enchantment bonus from weapon

A hit roll over 0 is a hit unless the random number is 1, which is always a miss. A random number of 20 is always a hit and always double damage.

Damage rolls are much more complicated. Damage depends on the weapon. Define the damage of a weapon by giving it an ATK value that corresponds to a defined damage range on the table below. Using a non-defined ATK value will either give zero damage or crash the game, so don't do it, it wouldn't make sense to do so anyway. Obviously states, accessories and armors that increase ATK value are non-sensical. Adding a damage range definition isn't hugely easy, but an example is provided (1d12) for those who wish to do so.

1d6 - 1, for an example, means a six-sided die is simulated, and the resulting value that results has 1 subtracted from it.

ATK values and their corresponding damage rates:
------------
1 = 1d3 -1
2 = 1d4 -1
3 = 1d6 -1
4 = 1d8 -1
5 = 1d10 -1
6 = 2d8 -1
7 = 1d3
8 = 1d4
9 = 1d6
10 = 1d8
11 = 1d10
12 = 2d8
13 = 1d3 +1
14 = 1d4 +1
15 = 1d6 +1
16 = 1d8 +1
17 = 1d10 +1
18 = 2d8 +1
19 = 1d3 +2
20 = 1d4 +2
21 = 1d6 +2
22 = 1d8 +2
23 = 1d10 +2
24 = 2d8 +2
25 = 1d3 +3
26 = 1d4 +3
27 = 1d6 +3
28 = 1d8 +3
29 = 1d10 +3
30 = 2d8 +3
31 = 1d3 +4
32 = 1d4 +4
33 = 1d6 +4
34 = 1d8 +4
35 = 1d10 +4
36 = 2d8 +4
37 = 1d3 +5
38 = 1d4 +5
39 = 1d6 +5
40 = 1d8 +5
41 = 1d10 +5
42 = 2d8 +5
------------

Some referrences:
1d3 = fist
1d6 = short sword
1d8 = longsword
2d8 might be an exotic weapon/demon natural weapon

Plans for future on this script:
The next step is to make a turn-based Gold-Box style battle system (similar to a SRPG battle system) but that is *way* off in the distance, and would be a seperate script anyway that I would try to make compatible with this one, but not dependent on it. But this could be fun to play around with, so I'm putting it up.

There. It should work I'm not really sure how many people want to turn

O wow. Used this in my project, it does exactly what I wanted it to. Thanks!

but it seems to work perfectly so thanks again!

Hey does anyone know where else I might be able to find the demo for this? the link is broken or outdated or something and is no longer available here.
I'd like to see how the author configured armor to see if I'm doing it right so if anyone knows where I can find it, please let me know.

Thanks!

Hey I hope someone reads this because there is some information I need pertaining to this script.

I need to know if the attack value changes that form the different die sizes also apply to the attack powers of enemies as well, or do the enemies use the original algorithm for attack power?

Please, if someone familiar with scripting could look over this script and find out if the enemies attack powers are included in the algorithms for different die sized attacks, then I would extremely grateful. I've tested it and its just too hard for me to tell.

Thanks in advance!

If you placed it in Game_Battler, it will affect the enemies as well

Unfortunately though, I can't seem to find a copy of the demo anywhere

[Fixxxer4153]

Well its in Game_Battler3 just as was instructed. So yes it works for enemies?

I encountered an error with this script. I put it in my game, and changed all the values to work, but when I have the character attack, there is an error on line 556. It claims that the method "Guarding" is undefined..

moodgiesanta accidentally uses self.guarding in his script, instead of self.guarding?

I'll change that in the original, but when the error comes up for you, go into the script editor, and put a ? at the end of the self.guarding and that should fix it

Ah. I see. Thank you.
