Battle system. (RPG Style)

I've seen this discussed before but can someone please help me with a battle system. I just need some pointers like. How would I make multiple enemies of different types. I want to create one similar to earthbound.

There are many ways you could do this. Likely the best way, as mentioned by Toad would be to use an array.

DIM TYPE
DIM ATTACK[A,AM]

Where TYPE is the type of enemy. When you get into a battle use RND, so if a 1 comes up, that's enemy type 1 and so on. Then ATTACK is 2-dimensional, where A is which attack is being used, and AM is the attack damage amount. This is just the beginning though and would not suffice as a very good system on it's own. Rather than just doing a random attack each time you could use a series of IF statements (in lue of a SWITCH CASE) to determine which attack should be used in certain scenarios. Something like: EHP = Enemy HP

IF EHP<20 THEN
  A = DEFENSEUP;
ENDIF

Also, rather than using a set damage amount or even random, you can use some fairly simple formulas to determine the amount. You can also do something like: If to hit < Toughness/Deflection: Damage = Random(Weapon's min damage, weapons, max damage) - opponent's armor value Else: Damage = Random(Weapon's min damage, weapon's max damage) However, you should start simple, and then decide if you want to implement more complicated formulas. Once you start basing damage calculations on character levels it gets a bit complicated. You can start with a fixed damage system, where damage varies only by weapon. (The damage still varies, it just doesn't matter who uses said weapon)

You could have some randomly generated number thing for multiple enemies to load them into the battle system, though that may not be the best way to go about making it. Also, could you specify what you mean exactly by "How would I make multiple enemies of different types"? All that I think it would involve is maybe having different sprites and attacks honestly. And I'm not completely sure how one would go about making a roulette hp bar thing. This just reminds of how I was thinking about making a simple battle engine for a game I was making, so maybe I could try implementing some of the stuff you mentioned in it.

I was asking about How would I make each enemy differ from the others. Its kinda hard to explain. I'm not really good with data And when it comes to things like making battle systems I'm no good. What I mean is like have 5 enemy slots And when you have an encounter The slots are filled with random enemy data Such as

If EnemyGroup==1 then E1=5:E2=3

Then Slot one would be a bird monster And slot 2 would be a beast. I just don't know how I would go about giving each one a separate HP While making them do the same thing (Battle,heal themselves and etc,) I have trouble will slot things too because idk how data works.

Yeah I use a formula like this Attack=Atk+Weapon damage-Enemydefense EnemyHp=EnemyHp-attack I really like your way too though, I might combine the two

Awesome, yeah just experiment, it will come to you eventually!

Try this:

DIM ENGROUP[3,3]
RESTORE @GROUPDATA

FOR J=0 TO 2
 FOR I=0 TO 2
  READ ENGROUP[I,J]
 NEXT
NEXT

@GROUPDATA
DATA 1,5,1
DATA 3,2,5
DATA 1,1,1

You can then set the monster types like this:

DIM EN[3]
GROUP=0

FOR I=0 TO 2
 EN[I]=ENGROUP[GROUP,I]
NEXT

Can't test it right now, but it should work. Also, don't be afraid to use arrays for everything, the Nintendo 3DS basically has unlimited memory when it comes to making things with SmileBASIC.

Thank you for your help!

I'm gonna try that. I haven't been good with arrays but you broke it down really well so I'm gonna try it, Thank you!

Try this:

DIM ENGROUP[3,3]
RESTORE @GROUPDATA

FOR J=0 TO 2
 FOR I=0 TO 2
  READ ENGROUP[I,J]
 NEXT
NEXT

@GROUPDATA
DATA 1,5,1

So the data setup works how would I use the data arrays Like how would I use this to setup the enemies.

Do you mean HP and stuff? This is just for enemy groups. So if enemy 1 was a skeleton and enemy 5 was a goblin, then this:

DATA 1,5,1

would make the enemies appear in the order skeleton, goblin, skeleton, in battle. That's all it does. Of course, the enemies that appear would be the ones you make yourself.

Oh okay, In one case I know how to make them appear like : If EnemyN==1 then spset 0,678 (monster 1) I just don't know how I would take the Data and use it to do something like that Like how would I take the number 1,5,1 and use it Sorry if its annoying I really appreciate your help

It's okay, I'll help whenever I'm not busy (with homework and stuff). You don't need to use 1 or 5, it was just an example, you can use sprite numbers, but it'd be hard to remember them if you use them them a lot. I hope that I haven't confused you, and good luck with your game!

Would I use the read command to use the numbers Like how would I use the numbers... How would I take the numbers from the array and use them for player data

The READ command is for filling the array with data, not reading from it, silly, right? Instead we'd do something like this:

DEC HP,EN[0,3]' Decrease player's HP by enemy's attack power
'or this:
HP = HEAL[3] 'Player's HP variable becomes the fourth value in the HEAL array

Sorry for the extremely late reply, I don't use this site very much.

Its okay I appreciate you answering my questions. This is what I needed thank you!

How would I use the Data for making the enemies appear in the battle... Nothing I try is working. Like Say 1= Goblin 2= Beast 3= Snake I set up a data array like @Edata Data 1,2,3 How would I use the data in the loop to make the enemy appear.

Either you READ VAR1,VAR2,VAR3 or READ ARR I think. I haven't messed with multiple data values on the same line.

I kinda wanna do a slot system. There are four empty slots where enemies could be. Each slot contains a blank enemy HP,Atk,Def,Mana,Sp,Hit rate. Then it fills the slots when data is read, The problem is.. I'm clueless. I don't even know how to start.

Well one way I know how to do that is by loading a dat file with custom data. I'm using something similar for my emulator (load a text-based config which defines a custom instruction set and emulation parameters and load a dat-based BIOS file which contains custom boot code). You can define your enemy data using a text-based configuration file or you can save/load it in the dat format. For an unencrypted text format configuration system you can do the slot thing in a few different ways. One way is to store each slot's data in a separate text file. Let's say it contains the text data "1:1;10" where the first number is level, the second is attack damage, and the third is hp count. The ":" and the ";" designate separation points". You can also use the newline character (CHR$(10)) to make the data multiline. You can even use tags such as "ENEMY0:" which is useful in a single multiline configuration file which contains all the enemy slot data. This can be a bit complicated but it does make editing your enemy data without editing the main code easier. (option 2) A more easier and compact way to do that is to store arrays in dat files. Because it's so easy and simple I'll make a little code example:

DIM ENEMY[4,3] 'Four enemy types, three variables per enemy. Of course you don't really need to define the dimensions when loading a file unless you're creating a new one.

IF CHKFILE("DAT:ETYPE") THEN
 LOAD "DAT:ETYPE",ENEMY
 'Code for whatever...
 ENDIF
'More code for whatever such as what to do if there is a missing file (you might want to change ENDIF to ELSEIF)...

As you can see the second option is very simple. The first option woulld require a lot more code such as code for determining tags, string management, etc. If you want to make the second option load different files for different slots make multiple 1d arrays and do a bunch of save/load operations for how many slots you want. That's not a good idea because it would get messy. If you don't want to mess around with code each time you want to make changes to an enemy you can make a separate program (or DEF function in the main code) which loads the dat file and has a gui of some type so you can see what stored data there is so you can manipulate it with said gui. TL;DR read everything below (option 2)

Try this:

'I don't know what type of game you're making, so I'm using an RPG as an example
CLS
DIM EN$[3,3] 'You can only have string (text) or integer (number) arrays, not a combination of both 

RESTORE @EDATA
FOR J =0 TO 2
 FOR I=0 TO 2
  READ EN$[I,J]
 NEXT
NEXT

MYHP=100
MYPOW=4

PRINT EN$[0,0]+", "+EN$[1,0]+" and "+EN$[2,0]+" are ready to fight!" 'Enemy names
PRINT "HP:"+EN$[0,1]+" HP:"+EN$[1,1]+" HP:"+EN$[2,1]
PRINT "My HP:" + STR$(MYHP)

WAIT 150
PRINT "You attack "+EN$[2,0]+" for "+STR$(MYPOW)+" damage!" 'Enemy 3
EN$[2,1]=STR$(VAL(EN$[2,1])-1)

WAIT 150
PRINT EN$[0,0]+", "+EN$[1,0]+" and "+EN$[2,0]+" are ready to fight!"
PRINT "HP:"+EN$[0,1]+" HP:"+EN$[1,1]+" HP:"+EN$[2,1]
PRINT "My HP:" + STR$(MYHP)
PRINT EN$[1,0]+" attacks you for "+EN$[1,2]+" damage" 'Enemy 2's attack power
MYHP=MYHP-VAL(EN$[1,2])

WAIT 150
PRINT EN$[0,0]+", "+EN$[1,0]+" and "+EN$[2,0]+" are ready to fight!"
PRINT "HP:"+EN$[0,1]+" HP:"+EN$[1,1]+" HP:"+EN$[2,1]
PRINT "My HP:" + STR$(MYHP)

WHILE TRUE
WEND

@LEVEL1ENEMYDATA 'You can make multiple data labels for different levels and use RESTORE to get this data, then use READ (shown above) to store it into an array
DATA "Goblin","30","5"
DATA "Beast","40","7"
DATA "Snake","15","5"

Also can't test this code, but don't worry if you can't understand it, I'll be here to help whenever I can. :)

Thanks to every one who helped. I have a working system. Its simple but it works. You guys opened my mind to arrays and it helped a lot. Thank you. Elaysia would have been put on Hiatus if not for your help. Thanks so much. Hope you guys play it when it comes out!
