/*
* Move relearner state machine
* ------------------------
*
* Entry point: TeachMoveRelearnerMove
*
* TeachMoveRelearnerMove
* Task_WaitForFadeOut
* CB2_InitLearnMove
* - Creates moveDisplayArrowTask to listen to right/left buttons.
* - Creates moveListScrollArrowTask to listen to up/down buttons.
* - Whenever the selected move changes (and once on init), the MoveRelearnerCursorCallback
* is called (see sMoveRelearnerMovesListTemplate). That callback will reload the contest
* display and battle display windows for the new move. Both are always loaded in
* memory, but only the currently active one is copied to VRAM. The exception to this
* is the appeal and jam hearts, which are sprites. MoveRelearnerShowHideHearts is called
* while reloading the contest display to control them.
* DoMoveRelearnerMain: MENU_STATE_FADE_TO_BLACK
* DoMoveRelearnerMain: MENU_STATE_WAIT_FOR_FADE
* - Go to MENU_STATE_IDLE_BATTLE_MODE
*
* DoMoveRelearnerMain: MENU_STATE_SETUP_BATTLE_MODE
* DoMoveRelearnerMain: MENU_STATE_IDLE_BATTLE_MODE
* - If the player selected a move (pressed A), go to MENU_STATE_PRINT_TEACH_MOVE_PROMPT.
* - If the player cancelled (pressed B), go to MENU_STATE_PRINT_GIVE_UP_PROMPT.
* - If the player pressed left or right, swap the move display window to contest mode,
* and go to MENU_STATE_SETUP_CONTEST_MODE.
*
* DoMoveRelearnerMain: MENU_STATE_SETUP_CONTEST_MODE
* DoMoveRelearnerMain: MENU_STATE_IDLE_CONTEST_MODE
* - If the player selected a move, go to MENU_STATE_PRINT_TEACH_MOVE_PROMPT.
* - If the player cancelled, go to MENU_STATE_PRINT_GIVE_UP_PROMPT
* - If the player pressed left or right, swap the move display window to battle mode,
* and go to MENU_STATE_SETUP_BATTLE_MODE.
*
* DoMoveRelearnerMain: MENU_STATE_PRINT_TEACH_MOVE_PROMPT
* DoMoveRelearnerMain: MENU_STATE_TEACH_MOVE_CONFIRM
* - Wait for the player to confirm.
* - If cancelled, go to either MENU_STATE_SETUP_BATTLE_MODE or MENU_STATE_SETUP_CONTEST_MODE.
* - If confirmed and the pokemon had an empty move slot, set VAR_0x8004 to TRUE and go to
* MENU_STATE_PRINT_TEXT_THEN_FANFARE.
* - If confirmed and the pokemon doesn't have an empty move slot, go to
* MENU_STATE_PRINT_TRYING_TO_LEARN_PROMPT.
*
* DoMoveRelearnerMain: MENU_STATE_PRINT_TRYING_TO_LEARN_PROMPT
* DoMoveRelearnerMain: MENU_STATE_WAIT_FOR_TRYING_TO_LEARN
* DoMoveRelearnerMain: MENU_STATE_CONFIRM_DELETE_OLD_MOVE
* - If the player confirms, go to MENU_STATE_PRINT_WHICH_MOVE_PROMPT.
* - If the player cancels, go to MENU_STATE_PRINT_STOP_TEACHING
*
* DoMoveRelearnerMain: MENU_STATE_PRINT_STOP_TEACHING
* DoMoveRelearnerMain: MENU_STATE_WAIT_FOR_STOP_TEACHING
* DoMoveRelearnerMain: MENU_STATE_CONFIRM_STOP_TEACHING
* - If the player confirms, go to MENU_STATE_CHOOSE_SETUP_STATE.
* - If the player cancels, go back to MENU_STATE_PRINT_TRYING_TO_LEARN_PROMPT.
*
* DoMoveRelearnerMain: MENU_STATE_PRINT_WHICH_MOVE_PROMPT
* DoMoveRelearnerMain: MENU_STATE_SHOW_MOVE_SUMMARY_SCREEN
* - Go to ShowSelectMovePokemonSummaryScreen. When done, control returns to
* CB2_InitLearnMoveReturnFromSelectMove.
*
* DoMoveRelearnerMain: MENU_STATE_DOUBLE_FANFARE_FORGOT_MOVE
* DoMoveRelearnerMain: MENU_STATE_PRINT_TEXT_THEN_FANFARE
* DoMoveRelearnerMain: MENU_STATE_WAIT_FOR_FANFARE
* DoMoveRelearnerMain: MENU_STATE_WAIT_FOR_A_BUTTON
* DoMoveRelearnerMain: MENU_STATE_FADE_AND_RETURN
* DoMoveRelearnerMain: MENU_STATE_RETURN_TO_FIELD
* - Clean up and go to CB2_ReturnToField.
*
* DoMoveRelearnerMain: MENU_STATE_PRINT_GIVE_UP_PROMPT
* DoMoveRelearnerMain: MENU_STATE_GIVE_UP_CONFIRM
* - If the player confirms, go to MENU_STATE_FADE_AND_RETURN, and set VAR_0x8004 to FALSE.
* - If the player cancels, go to either MENU_STATE_SETUP_BATTLE_MODE or
* MENU_STATE_SETUP_CONTEST_MODE.
*
* CB2_InitLearnMoveReturnFromSelectMove:
* - Do most of the same stuff as CB2_InitLearnMove.
* DoMoveRelearnerMain: MENU_STATE_FADE_FROM_SUMMARY_SCREEN
* DoMoveRelearnerMain: MENU_STATE_TRY_OVERWRITE_MOVE
* - If any of the pokemon's existing moves were chosen, overwrite the move and
* go to MENU_STATE_DOUBLE_FANFARE_FORGOT_MOVE and set VAR_0x8004 to TRUE.
* - If the chosen move is the one the player selected before the summary screen,
* go to MENU_STATE_PRINT_STOP_TEACHING.
