| In rpg games like Final fantasy, when you attack an enemy, the amount of damage you do is random, So how would you do randomness in the ti83+? |

| Actually, the amount of damage is not random completely, it can depend on your stats. The random integer function is randInt( I think. Find it in the Math menu or the catalogue. |

yes, RandInt(1,10) (math->left once->down 5->enter) would return a pseudorandom integer between 1 and 10, inclusive
rand returns a pseudorandom # between 0 and 1, i think, but i havent used that one as much...

or just:
Code:
IPart(rand*[any number you choose])
That will put in a random # that doen't have any decimals up to the # you choose |

RandInt( is faster (and takes less memory?).
How you can base it on your strat:
Say your character has strength 5 and that value is stored in LRPG(4)
You can either rule your strength is the max damage you can do,
RandInt(0,LRPG(4)->D
or that you add strength to a base roll (as is the case in most rpg's, including DnD)
RandInt(1,6)+LRPG(4)->D

Quote: RandInt(1,6)+LRPG(4)->D
ahhh the is right, but in many RPGs i acctually do less damage than what is the avg. or what not. this is what i do: (assuming that LRPG(4 is the strength
Code:
RandInt(0,10)->A (no need for the ")" but ohh well it is easier to see...)
RandInt(1,2)->B
If B = 1
Then
LRPG(4)+A
End
If B=2
Then
LRPG(4)-A
End
It takes a little more, but adds more randomness to the game |

D //damage rolled
B // enemy's toughness/armour
A //enemy's HP
RandInt(1,6->D
Repeat fPart(Ans/6 //keep adding D6 damage until lower than 6 is rolled
D+(D=6)RandInt(1,6->D //add another D6 damage to the roll if it was a critical one (rolling a 6 for damage would be a critical)
End
A-(D+LRPG(4)-B->A //substract damage from enemy's HP
The reason you do less damage than average is because your enemy is probably wearing armour or has some other way of reducing damage (toughness, magic items, etc.) or because you are getting penalties for some reason (in DnD for example, when you use a weapon in your off-hand (left) you get a -4 (right arm) -4 (left arm) chance to hit unless you have appropriate skills)

iPart(X) - returns the integer part of X
fPart(X) - returns the floating part (decimal) of X |

iPart(5.6789) = 5
fPart(5.6789) = 0.6789
Usefull when decompressing data, for example:
46->A //player x coord
30->B //player y coord
100A+B->LSAVE(1 //save
iPart(.01LSAVE(1->A //load A
100fPart(.01LSAVE(1->B //load B

why are there 2 functions - int( and iPart( that do the same thing?
randInt(0,N is faster than int((N+1)rand but takes more space if N is a constant. They are both best in some cases.
