Combat system

[Mayley]

Ok so i'm making a text based Rpg game, but the one stubling block on is the combat system.

At the moment i have a general idea of what i want to happen.

Points
Triangle attack system
e.g Magic > Block > Attack > Magic
Turn based system between player and mob
Option to leave combat on your go.
Option to use different spells if possible.


Now the way have thought about doing it is to use if possible is

Write (Pick an attack option block, magic, attack
Read (choice)
choice = uppercase choice

Randomrange mob(3,10)     Used to random to different mobs e.g skeleton and zombie
for mob[x] get mob stats from defined mob health [need help here]

Case choice of
Magic:Magic
block:Block              with the magic block and attack being a function of somekind?
Attack:attack

Mob attack = randomrange (1,3) 1:block 2:Attack 3:magic
If mobattack= block and playerattack = magic then
Player = hit mob
If mobattack = block and playerattack = attack then
mob = hit player 
If Mobattack = block and playerattack = block then
draw

If mob attack = attack and player attack = magic then
mob = hit player
If mobattack = attack and player attack = block then
player = hit mob
If mobattack = attack and player attack = attack then
Mob = hit player
player = hit mob

If mobattack = magic and playerattack = magic then
mob = hit player
player = hit mob
if mobattack = magic and playerattack = block then
mob = hit player
if mobattack = magic and playerattack = attack then
player = hit mob

In this i want the mob's hp to be decided from a procedure or function where i can have each mob defined.

I was just wondering if you guys think this system would work or not as pesudocode and how well you think it would work.

For clarity i'd make another function (still pseudo):

function IsCountered(action, defence): boolean
  result = true
  if action = attack then
    if (defence = magic) or (defence = attack) then
      result = false
  else if action = magic then
    if (defence = magic) or (defence = block) then
      result = false
  else if (action = block) and (defence = attack) then
    result = false

Main app:

player_attack_blocked = IsCountered(player_attack, mob_attack)
mob_attack_blocked = IsCountered(mob_attack, player_attack)
if not player_attack_blocked then
  hit mob
if not mob_attack_blocked then
  hit player
if player_attack_blocked and mob_attack_blocked then
  draw
