Scripts:Power Up

From OHRRPGCE-Wiki
Jump to navigationJump to search

Let's say you have a Fire Rod in your game, which you want to improve the power of fire spells. Or you have a Pendant that unlocks the power of the Masamune, making it stronger. You can create these effects with this plotscript. The trick is that the powered-up fire spell and sword are actually a different attack/item -- the script switches between them.

Script[edit]

# POWER UP

script, power up (
 if (key is pressed(key:alt)) then (
  wait(0) # Allow the menu to close
  variable(hero)
  variable(slot)
  variable(list)
  for (hero, 0, 40) do (
   # Change Fire to Fire 2 if Fire Rod is equipped
   if (check equipment(hero, slot:weapon) == item:Fire Rod) then (
    # If the hero has the normal spell, power it up
    if (knows spell(hero, atk:Fire)) then (
     for (list, 0, 3) do (
      for (slot, 0, 23) do (
       if (read spell(hero, list, slot) == atk:Fire) then (
        write spell(hero, list, slot, atk:Fire 2)
       )
      )
     )
    )
   ) else (
    # If the hero has the powered-up spell, change it to normal
    if (knows spell(hero, atk:Fire 2)) then (
     for (list, 0, 3) do (
      for (slot, 0, 23) do (
       if (read spell(hero, list, slot) == atk:Fire 2) then (
        write spell(hero, list, slot, atk:Fire)
       )
      )
     )
    )
   )
 
   # Change Masamune to Masamune 2 if Pendant is equipped
   if (check equipment(hero, slot:arms) == item:Pendant) then (
    # If the hero has the weak Masamune, power it up
    if (check equipment(hero, slot:weapon) == item:Masamune) then (
     force equip(hero, slot:weapon, item:Masamune 2)
    )
   ) else (
    # If the hero has the powered-up Masamune, change it back
    if (check equipment(hero, slot:weapon) == item:Masamune 2) then (
     force equip(hero, slot:weapon, item:Masamune 2)
    )
   )
  )
 )
 # We also need to swap out any Masamune 2s in inventory
 if (inventory(item:Masamune 2)) then (
  get item(item:Masamune, inventory(item:Masamune 2))
  delete item(item:Masamune 2, inventory(item:Masamune 2))
 )
)

Usage[edit]

This script should be set as the on-keypress script. If you already have an on-keypress script, you can still use this one -- just copy its contents into your own script. The script has some limitations:

  • You shouldn't use it if you have multiple copies of the same hero.
  • It won't change anything while the menu is open. For example, if the player changes his equipment and casts a spell without leaving the menu, he'll get the original spell instead of the new one.
  • Along the same lines, it's a bad idea to make the powered-up item have different stat changes. This will confuse the player. You can make it more powerful by giving it a different attack instead.
