Damage...

[+acadiel]

Every game is a little different. Take, for example, the Vita MMORPG type game Sword Art Online, Hollow Fragment. (Guide is here.) There's a long winded discussion at the first URL linked about someone wanting to know how DPS Total, DMG, ATK and STR all factored into the game... for example:

 

"The axe esoteric skill has a (+STR180% & VIT180% & DEX100%) adjustment value, which is calculated as (+DMG10% & STR190% & VIT180% & DEX100%). In terms of damage increases for that esoteric skill, 1 STR = 1.05 VIT = 1.9 DEX = 19 DMG. If you are using an axe, weapon parameters to prioritise would be would be STR > VIT > DEX > DMG. When casting the esoteric skill, an axe with 100 DMG and 50 STR would deal the same damage as an axe with 1050 DMG and 0 STR."

 

So, mapping to skills and items is one thing - how many different assets are you going to have that will modify damage stats?

 

Some other things (just thinking out loud): You can even minimize damage by applying a divider if you have a "block" or "dodge" move. Also, take into account a "miss" being completely random, and causing 0 damage. You could miss swinging a weapon, or you can even miss dodging (which means you get whatever damage you were intended to anyway).

 

I can't wait to see your game!

Here's a bare-bones tester (RANDOMIZED) to test out some of the formula ideas from Ksarul.... Seems to work really well. I played it 6 times, won 4 lost 2.

 

Thanks for the formula, Jim! I needed to tweak the variable values a little bit to create parity, but the equation works nicely! Paste into Classic99 and RUN to whack a skeleton with a tree branch!

You could easily wrap this in another loop and run X iterations to ensure you get a distribution you like.

Hmmm played it with Classic99 on XB, RXB 2012, RXB 2015 and did not win once?

 

Played 10 games each, the XB one was the only one I got close for the Skeleton won.

[Opry99er]

Got waxed, eh Rich? LOL!! Maybe youre not holding your tongue right or something, I dont know.

 

Ill give it another spin... But I did win 4 of 6 last night... Ill check to make sure I posted the most recent code (with updated DEF and ATK values)

 

Thanks for giving it a shot.

[Opry99er]

Played it one time just now. One victory.

 

 

Don't know, Rich..

[Opry99er]

You could change line 130 to SKDEFMOD=1.

 

Thatll tip the scales some.

I somehow missed this post, Jon! Thanks for posting that link... Some cool info there, for sure.

 

As far as the melee attacks in my own battle engine, really only focusing on the ATK value, the modifier(s) of that value (as I believe STR is simply a part of the ATK value as a whole and I really do not see any need for it in battle) and DEF and it's modifier(s).

 

Magic will be a little more detailed, by necessity... It is in this field I will be focusing a good chunk of my attention on study and research. MATK and MDEF are primaries, but Class and level will also come into play.

 

Elemental considerations will also be factored... If you are facing an Ice Golem and you cast FireSlash, you will do significant damage, because of the elemental differences. Conversely, IceBlast will do next to nothing.

 

Much of the elemental stuff will be tied into what is equipped to a specific party member... If you're facing a Flame Wraith and you have a FireShield equipped, damage from melee attacks from the Wraith will be significantly lessened.

 

 

There is still much reaearch and testing to do, but I feel I have a pretty good feel on what I am HOPING to accomplish. Will take work, time, study, coding, debugging, and a ton of testing and adjusting to get it where I want it.

 

Thanks for responding, bud.

[Opry99er]

Looks like I WILL need some additional modifiers. LOL!! For class differentiation, I would like for stats to grow at differing levels.

 

It is easy to differentiate class at low levels, as I can just have different starting values which distinguish party members from one another... In this way, a Level 1 thief could have an ATK value if 1, and a Level 1 fighter could have an ATK value of 5. Good separation there. However, if both members increase levels simultaneously and their stats increase at the same rate, a Level 20 thief and a Level 20 fighter would have relatively identical ATK values when it comes to combat. Basically I am saying, without additional modifiers, the higher the level, the less the classes matter.

 

I do not want that.

 

I need to study some more, obviously... At LEAST I will need modifiers like STR, INT, and AGI. (INT more for the magic casting and defense in battle)

 

Ya know... It pays to study the wheel before trying to reinvent it. LOL!!

[Opry99er]

The more I think about this, ATK and DEF should be derived variables...

 

Maybe, something like:

 

ATK=STR+VIT :: DEF=AGI+VIT

ATKMOD=WEAPVAL :: DEFMOD=ARMORVAL

 

Then...

 

DAM=(INT(RND*ATK)+ATKMOD)-(INT(RND*DEF)+DEFMOD)

 

In this way, the algorith stays the same, but the variables used can be modified properly with level gains..

 

FIGHTER LEVEL UP:

STR=STR+2 :: AGI=AGI+1 :: VIT=VIT+1

 

THIEF LEVEL UP:

STR=STR+1 :: AGI=AGI+2 :: VIT=VIT+1

 

This brings the question... Should VITality ALSO be derived? It can be modified based on condition (poisoned, burdoned, etc) but should it be derived in some regard from the difference between MAX HP and CURRENT HP?

 

For instance, if your party member has a max health of 40, but is beat up to sh** and has a current HP is 5, should VITality not decrease? This would make melee attacks while injured less effective... Seems realistic to me.

[Opry99er]

Okay... In my insanity, I attempted to come up with a way to weight the character's physical "state" into the effectiveness (or lack thereof) of attack and defend. What resulted was a bloody mess.... I was able to get something to work, though... I had to drop the priority of that factor down quite a bit, but here's one way to make it work. Notice this code is slightly different than the last incarnation I posted. ATK and DEF are now "derived" variables, STRength, AGIlity, and VITality have been added. VIT is a derived variable, one which attempts to determine the character's physical state by dividing his HP by his MHP... Them multiplying by 5 to give a vitality rating. ( I initially multiplied by 10, but this was madness)... This is added to STR (for attack) and AGI (for defense)...

 

Notice that ATKMOD and DEFMOD have been replaced by more concrete values, WEPVAL (the +rating of the weapon equipped) and ARMVAL (the +rating of the armor equipped)..... It is a work-in-progress, but I think I'm at least getting SOMEWHERE in the melee portion of the battle sequence. Tweaking needs to occur, but if you play through this a few times, you will see that the power of the attacks and the effectiveness of the defense decrease as the player "weakens"... The farther the HP drops from the MHP, the more "tired" the character becomes.

 

If you want to REALLY see this in action, change the values in LINE 110 to "100" and "100" and change the value in LINE 180 to "100"... This will give both the hero and the skeleton much higher starting health points, letting the demo run a bit longer so you can observe the changes in effectiveness. This will not affect VITality, as it is simply a calculation of percentage of health... wouldn't matter if you changed the value to 1,000,000, the number would be the same.
