[Scripting Question] Make party screen remember last selected slot

[silentgamer64]

I'm changing Essential's default party screen and I'm looking for a way to have the screen remember the last Pokemon that was selected before it changed to the current selection. I was able to do this for the storage party screen (in PScreen_Storage) shown below:

Spoiler:

And here's the code that allows this screen to remember the last selected pokemon on the right list when scrolling left/right between it and the lead pokemon (changes highlighted):

Spoiler:

def pbPartyChangeSelection(key,selection[S-HIGHLIGHT],lastsel[/S-HIGHLIGHT])# lastsel from pbSelectPartyInternal
    case key
    when Input::UP#LEFT
      selection-=1
      selection=6 if selection<0
    when Input::DOWN#RIGHT
      selection+=1
      selection=0 if selection>6
    when Input::LEFT#UP
      if selection==6
        #selection=5
        #If CANCEL is selected, LEFT shouldn't do anything.
      else
        #selection-=2
        #If any other slot is selected, move cursor to slot 0 (first slot)
        selection=0
        selection=6 if selection<0
      end
    when Input::RIGHT#DOWN
      if selection==6
        #selection=0
        #If CANCEL is selected, RIGHT shouldn't do anything.
      else
        #selection+=2
        [S-HIGHLIGHT]if selection == 0 #Sets selection to last selected pokemon on the right list if current selection is slot1          
           selection=lastsel
        end[/S-HIGHLIGHT]
        selection=6 if selection>6
      end
    end
    [S-HIGHLIGHT]lastsel = selection #Updates the last selected pokemon by setting it equal to current selection[/S-HIGHLIGHT]
    return selection
  end

  def pbSelectPartyInternal(party,depositing)
    selection=@selection
    pbPartySetArrow(@sprites["arrow"],selection)
    pbUpdateOverlay(selection,party)
    pbSetMosaic(selection)
  [S-HIGHLIGHT]  lastsel=1 #defaults lastsel to 1 (slot 2 in party screen)[/S-HIGHLIGHT]
    loop do
      Graphics.update
      Input.update
      key=-1
      key=Input::DOWN if Input.repeat?(Input::DOWN)
      key=Input::RIGHT if Input.repeat?(Input::RIGHT)
      key=Input::LEFT if Input.repeat?(Input::LEFT)
      key=Input::UP if Input.repeat?(Input::UP)
      if key>=0
        pbPlayCursorSE()
        newselection=pbPartyChangeSelection(key,selection[S-HIGHLIGHT],lastsel[/S-HIGHLIGHT]) #lastsel from pbPartyChangeSelection
        if newselection==-1
          return -1 if !depositing
        [S-HIGHLIGHT]elsif newselection==-2
          selection=lastsel #Selects last selected pokemon on right list internally[/S-HIGHLIGHT]
        else
          selection=newselection
        end
        pbPartySetArrow(@sprites["arrow"],selection)
        [S-HIGHLIGHT]lastsel=selection if selection>0#only sets lastsel value if selection isn't the lead pokemon[/S-HIGHLIGHT]
        pbUpdateOverlay(selection,party)
        pbSetMosaic(selection)
      end
      pbUpdateSpriteHash(@sprites)
      if Input.trigger?(Input::C)
        if selection>=0 && selection<6
          @selection=selection
          return selection
        elsif selection==6 # Close Box 
          @selection=selection
          return (depositing) ? -3 : -1
        end
      end
      if Input.trigger?(Input::B)
        @selection=selection
        return -1
      end
    end
  end

I figured I could easily do the same thing in PScreen_Party for the general party screen with a similar layout shown here:

Spoiler:

The code section for this in PScreen_Party is similar enough to the section in PScreen_Storage that I thought I could easily create the same behavior, but it turns out it's much different than I hoped it would be. Here's what I have so far (changes highlighted):

Spoiler:

def pbChangeSelection(key,currentsel[S-HIGHLIGHT],lastsel[/S-HIGHLIGHT])
    numsprites=(@multiselect) ? 8 : 7 
    case key
    when Input::UP
      begin
        currentsel-=1
      end while currentsel>0 && currentsel<@party.length && !@party[currentsel]
      if currentsel>[email protected] && currentsel<6
        [email protected]
      end
      currentsel=numsprites-1 if currentsel<0
    when Input::DOWN
      begin
        currentsel+=1
      end while currentsel<@party.length && !@party[currentsel]
      if [email protected]
        currentsel=6
      elsif currentsel==numsprites
        currentsel=0
      end
    when Input::LEFT
      if currentsel>=6
        #begin
          #currentsel=0#-=1 For cancel button, not needed since new button doesn't scroll left/right.
        #end while currentsel>0 && !@party[currentsel]
      else
        begin
          currentsel=0#-=2 For switching left to lead pokemon
        end while currentsel>0 && !@party[currentsel]
      end
      if currentsel>[email protected] && currentsel<6
        [email protected]
      end
      currentsel=numsprites-1 if currentsel<0
    when Input::RIGHT
      if currentsel>=5
        #currentsel+=1 For cancel button, not needed since new button doesn't scroll left/right.
      else
        #currentsel=1#+=2
        [S-HIGHLIGHT]if currentsel == 0 # This conditional checks for the last selected pokemon and selects it again.
          currentsel = lastsel
        end[/S-HIGHLIGHT]
        currentsel=6 if currentsel<6 && !@party[currentsel]
      end
      if currentsel>[email protected] && currentsel<6
        currentsel=6
      elsif currentsel>=numsprites
        currentsel=0
      end
    end
   [S-HIGHLIGHT] lastsel = currentsel[/S-HIGHLIGHT]
    return currentsel
  end
######################################
#Additional unchanged defs between these two blocks

def pbChoosePokemon(switching=false,initialsel=-1[S-HIGHLIGHT],lastsel[/S-HIGHLIGHT])
    for i in 0...6
      @sprites["pokemon#{i}"].preselected=(switching && i==@activecmd)
      @sprites["pokemon#{i}"].switching=switching
    end
    @activecmd=initialsel if initialsel>=0
    pbRefresh
    [S-HIGHLIGHT]lastsel=1[/S-HIGHLIGHT]
    loop do
      Graphics.update
      Input.update
      self.update
      oldsel=@activecmd
      key=-1
      key=Input::DOWN if Input.repeat?(Input::DOWN)
      key=Input::RIGHT if Input.repeat?(Input::RIGHT)
      key=Input::LEFT if Input.repeat?(Input::LEFT)
      key=Input::UP if Input.repeat?(Input::UP)
      if key>=0
        @activecmd=pbChangeSelection(key,@activecmd[S-HIGHLIGHT],lastsel[/S-HIGHLIGHT])
      end
      if @activecmd!=oldsel # Changing selection
        pbPlayCursorSE()
        numsprites=(@multiselect) ? 8 : 7
        for i in 0...numsprites
          @sprites["pokemon#{i}"].selected=(i==@activecmd)
        end
      end
      if Input.trigger?(Input::B)
        return -1
      end
      if Input.trigger?(Input::C)
        pbPlayDecisionSE()
        cancelsprite=(@multiselect) ? 7 : 6
        return (@activecmd==cancelsprite) ? -1 : @activecmd
      end
    end
  end

All it does is default to the second slot (which has the value of "1" since slot 1 has a value of "0").

TL;DR: How can I set lastsel equal to currentsel in pbChangeSelection without it defaulting back to 1?

Also, this is version 16 FYI, but I checked between 16 and 17 and didn't see any big changes to the party screen code as far as I could tell.

Honestly if I look at the code I'm not really sure if it is actually going to do what you want it to. I might be wrong since I haven't looked further into it. The reason I think is because you put the the part where it selects the last selection into an input and not at the part where the screen is started.

Anyway what also would be good to know if and where you put the code that actually stores the info on the last selection and what kind of variable it is
