Exception?

Yeah arrays can be confusing at first but they're dead useful when you get a handle on them

[GMG Mike]

Whoops, you beat me to it, but I have a question also, how are arrays saved to a file?

You could just write one line with the number of elements using COUNTARRAY and then one item per line.

Its a variable that can hold more than one value.
Say you have an amount of gold you win after each level of fighting. First you'd create the array
 
DIM goldAmount(50)
 
(50) means there are 50 slots within the variable goldAmount, you could use this as each level.
 
Then you'd assign a value to each slot:
 
LET goldAmount(1)=10
LET goldAmount(2)=15
LET goldAmount(3)=20
LET goldAmount(4)=25
etc...
 
So when you beat level one, you get 10 gold, level two, 15 gold and so on.
 
LET level=3
LET playerGold=playerGold+goldAmount(level)
 
 
Whoops, you beat me to it, but I have a question also, how are arrays saved to a file?

What if you wanted to do the opposite? When you get a certain amount of XP you gain a level?

[HarryCaray]

Code: [Select]

DIM xpLevel(50)//Just for the example the maximum level is 50
LET xpLevel(1)=0//At level "1", you need at least 0 xp
LET xpLevel(2)=100//At level "2", you need at least 100 xp
LET xpLevel(3)=500
etc...

Then, you'd check the xp every time you gain it.

LET temp=MAX(playerXP, xpLevel(playerLevel+1)//See which is higher, the player's xp or the next xp level
IF temp=xpLevel(playerLevel+1) THEN//This means the player has not reached the next level yet
NOTEALERT "You have not reached the next level as of yet!", "Sorry!"
ELSE
LET playerLevel=playerLevel+1//The player has more xp than the next level, so he gets to gain a level
END IF

I think this should work.

Thanks Harry!!!

This is cool, I think this might help with a program I was trying to make.
I'm curious, since an array is basically a list of numbers, can you use it to do something to multiple sprites? For example, if you have a list for all the enemies' numbers called enemies and then say CREATESPRITE (enemies) will it make more than one?

[Xiphos]

Code: [Select]

FOR x = 1 to enemies
IF spritevalid(x)=true THEN
Pushsprite x, -5, 0
END IF
NEXT

Not sure if arrays would but that would push them all.

EDIT: also put a make sure the sprites are valid.

**arrays allow you to use variables IN a variables name.**

heres an example of what arrays can do, say your doing an rpg with four enemies. without arrays you have to find the specific enemies hp variable to alter when you attack


if attackenemy=1 then let enemyHP1=enemyhp1-damage
if attackenemy=2 then let enemyHP2=enemyhp2-damage
if attackenemy=3 then let enemyHP3=enemyhp3-damage
if attackenemy=4 then let enemyHP4=enemyhp4-damage

with arrays you dont need to find it you just put the variable of the enemy your attacking in the name of the enemy's hp variable to match enemy

let enemyhp(attackenemy)=enemyhp(attackenemy)-damage

Thanks guys, that clears thigns up a lot.
 BTW, SOMEONE need to post a tutorial on that SC Wiki for these things, it's kind of empty...

[Connors]

IF spritevalid(x)=true THEN

There's what i was looking for... That's a useful command. XD
(I've been trying to remember where I saw it posted)

[EqwanoX]

it might be good to download sc 1.5 for syntax explanations, it uses all the same commands
