Damage

For Dark Resurrection I have the following formula for calculating damage:

-----------------------------------------------------
random = random modifier between 1 to 5
Damage = (( Att + W_Att ) - ( Def + W_Def )) + random
-----------------------------------------------------
It's possible to modify the damage further when you have a ring
in your inventory.

Att = Attacker's Attack value
W_Att = Attacker's Weapon Attack Modifier

Def = Defender's Defense value
W_Def = Defender's Weapon Defense Modifier

------------------------------------------------------------------------
For example:

- A Dark Sword has a -5 defense modifier
- A Demon Rod has a -10 defense modifier
- A Holy Lance had a +5 defense modifier

FYI: There are 85 weapons in Sf2 , only 5 of them have defense modifiers
------------------------------------------------------------------------

Miscellaneous:
--------------

Take a random number between 1 to 100

Double Attack = random => 91 and <=100
Critical Hit = random => 80 and <= 90
Normal Hit = random => 10 and <= 79
Miss = random => 0 and <= 9

Any suggestions ? Grin

Re: Damage

Definitely.
The random modifier needs to be smaller early on in the game.
If you plan on starting with similar HP's to shining force a random of 5 would be unbalanced.

Re: Damage

As Elv said, the random number of 5 is a little high. Using a percentage of the final value might be better.

There's also a few other things to take into account:
* Land Effect (increases defender's defence)
* Attack, Support and Slow spells
* Status effects such as paralysis - means defender less likely to dodge or counter

Possible other things:
* Weapon "alignment" - Holy swords/rods would be more effective against demons
* Weapon types - Shining Force 3 did this quite well. Arrows are good against flying enemies, as an example

Other than that, it looks good

For random damage, you could use a percentage of the defender's defence or attacker's attack. One tip is to add two random numbers, so you get a curve of values. For example:

Code:

(Rand(-2, 4) + Rand(-2, 4)) / 2

This will give more values around 1 and 0, with the occasional high number (and also a few negatives to keep things interesting). It's a bit like rolling two dice instead of one - you get more middle numbers and only a few extremes.

Hope that helps

Re: Damage

Thanks Ty, this will sure come in handy.

btw if you run this code in Blitz3D , you will see how many times a certain number
is generated.

Code:

Graphics 800,600,16,1
SetBuffer BackBuffer()

SeedRnd MilliSecs() 

While Not KeyDown( 1)

	Cls
	
	sol = (Rand(-2,4) + Rand(-2,4)) / 2

	num = num + 1

	Select Sol
		Case -2 times2a = times2a + 1
		Case -1 times2b = times2b + 1
		Case 0  times0  = times0 + 1
		Case 1  times1  = times1 + 1
		Case 2  times2  = times2 + 1
		Case 3  times3  = times3 + 1
		Case 4  times4  = times4 + 1
	End Select 

	Text 10,  25 , "total generated ....: " + num
	Text 10,  40 , "times -2 ...........: " + times2a
	Text 10,  55 , "times -1 ...........: " + times2b
	Text 10,  70 , "times 0  ...........: " + times0
	Text 10,  85 , "times 1  ...........: " + times1
	Text 10, 100 , "times 2  ...........: " + times2
	Text 10, 115 , "times 3  ...........: " + times3
	Text 10, 130 , "times 4  ...........: " + times4
	
	Text 10, 200 , "used formula : (Rand(-2,4) + Rand(-2,4)) / 2"

	
		
	Flip
Wend

and Ty, I may need your expertise again with calculating EXP. I'll come to that later

Thank you so far.

Re: Damage

I'll also chime in here on something I missed the first time reading your post.
I think misses and double attacks are based on agility stats(possibly with terrain effect modifier).

Making the chance to dodge equal for everyone doesn't seem right.

Re: Damage

Right.

I could program in such a way that it depends on AGI, or LUCK , or maybe both.

If Attacker's LUCK is high enough and Attacker's AGI is higher than Defender's AGI
then activate Double Attack or else a Normal Attack

We could do something like this for Miss:

If LUCK is low (or lowest) AND random number is between 0 & 9 AND Defender's AGI
is higher than Attacker's AGI then you have a missed attack.

Re: Damage

Sounds like you have a good basis there, remember to keep a random factor involved too though : ) Otherwise Amon and Balbory become both longer lasting and more devastating than Gort along with that awesome move speed.

//example, A is attacker, D is defender
temp=rand(5);
if( (A.agility+rand(10)-temp) > (D.agility+rand(10)+temp) ) { double attack }
if( (A.agility+rand(10)+temp) < (D.agility+rand(10)-temp) ) { miss }

It really depends on the range of stats you have and how often you want misses etc to crop up. I have absolutely no idea how luck works though, if it cycles over time then maybe it's already sweet as.

Re: Damage

If you run this code in Blitz, you'll see how LUCK is calculated over time.

Code:

Graphics 800,600,16,1

SetBuffer BackBuffer()

Global Luck#	= 5
Global AddLuck# = 0.1

time = MilliSecs()

While Not KeyDown(1)

	Cls
	
	If MilliSecs() > time + 500;180000
	
		time = MilliSecs()
		
		If Luck > 6 Or Luck < 1
			AddLuck = -AddLuck
		EndIf
		
		Luck = Luck + AddLuck
	
	EndIf
	
	Text 10,15, "LUCK (integer): " + Int(Luck) 
	Text 10,30, "LUCK (float): " + Luck

	Flip

Wend

End

Of course , luck-calculation takes a longer period of time. This is just a demo.

Re: Damage

What about an individual spike cycle?

ie: build luck as it isn't triggered, on triggering something considered lucky, some luck is released.

The above mentioned example is a generalization. Cheesy

I can assure you that each member of the Force has his own LUCK-variable.
So, no problems there.

Re: Damage

I'm guessing you're not including general items like angel wings, medical herbs etc : )
Some here from SF1

speed ring: egress
white ring SF1: aura 1

sword of light: bolt 2
sword of darkness: desoul 1
chaos breaker: freeze 3

halberd: bolt 1
valkyrie: boost attack

As for strength gains, you can find those details out in any decent guide.
Here's a good example from SF1 where I got some of these:

Code:

Short Sword          SDMN, WARR, BDMN          +5              -

 Middle Sword         SDMN, WARR, BDMN          +8              -

 Long Sword           SDMN, BDMN                +12             -

 Steel Sword          HERO, NINJ, SKYW, SMR     +16             -

 Broad Sword          HERO, NINJ, SKYW, SMR     +20             -

 Katana               HERO, NINJ, SKYW, SMR     +30             -
