DoubleX RMVXA Bug Fixes v1.05b to YSA Battle System: Classical ATB
by DoubleX
Note
v1.03a+ disables party escape while at least 1 battler is executing actions
Compatibility Fix
http://www.rpgmakervxace.net/topic/21113-doublex-rmvxa-compatibility-fixes-to-ysa-battle-system-classical-atb/?p=145964
Prerequisites
YSA Battle System: Classical ATB(Created by Yami)
Introduction
Tries to fix bugs I've found in YSA Battle System: Classical ATB
Fixing compatibility issues isn't this script's aim
Advices
- Fix some issues by following the ordering of YEA scripts:
Check http://yanflychannel.wordpress.com/rmvxa/ and follow the ordering
- Fix bugs when preemptives or susprises occur in the catb battle system:
Give numbers to PREEMTIVE_ATB_ACTOR, PREEMTIVE_ATB_ENEMY, SURPRISE_ATB_ACTOR and SURPRISE_ATB_ENEMY
- Fix some compatibility issues with other scripts:
Put this script below YSA Battle System: Classical ATB, which should be put below Yanfly Engine Ace - Ace Battle Engine
They should be placed as nearby each other as possible
Bugs tried to fix:
- (v1.05a)Buff/Debuff removal bug
Buffs and debuffs won't be removed even when their remaining turns reaches 0
- (v1.04a+)Victory defeat bug:
Windows that are supposed to be closed don't close if they are shown right before victory or defeat
- (v1.03a+)Battler escape bug:
Various crashes may occur when any battler escapes
- (v1.02a+)Collapse check bug:
Enemy sprite won't collapse when they die because of slip damage per turn
Causes:
Consider the following parts of method process_catb and perform_catb_action under class Scene_Battle respectively(YSA Battle System: Classical AT
:if $game_system.catb_turn_type == :tick @tick_clock = if !@tick_clock @tick_clock += 1 if @tick_clock >= $game_system.catb_tick_count @tick_clock = all_battle_members.each { |battler| battler.on_turn_end } @status_window.refresh $game_troop.increase_turn endend
Code:
if $game_system.catb_turn_type == :action @tick_action = if !@tick_action @tick_action += 1 if !forced || (forced && YSA::CATB::FORCE_ACTION_COUNT) if @tick_action >= $game_system.catb_after_action @tick_action = all_battle_members.each { |battler| battler.on_turn_end } @status_window.refresh $game_troop.increase_turn endendAs the collapse effect due to slip damage KO is checked per turn end and of the whole battle and YSA Battle System: Classical ATB simply get rid of the latter, the collapse check bug occurs as the above 2 parts didn't check the collapse effect when they're the only appropriate parts to do so.
- (v1.01a+)On turn end bug:
The whole "on turn end thing" of the whole battle simply won't be triggered at all in catb battle system
Causes:
Consider the following parts of method process_catb and perform_catb_action under class Scene_Battle respectively(YSA Battle System: Classical AT
:if $game_system.catb_turn_type == :tick @tick_clock = if !@tick_clock @tick_clock += 1 if @tick_clock >= $game_system.catb_tick_count @tick_clock = all_battle_members.each { |battler| battler.on_turn_end } @status_window.refresh $game_troop.increase_turn endend
Code:
if $game_system.catb_turn_type == :action @tick_action = if !@tick_action @tick_action += 1 if !forced || (forced && YSA::CATB::FORCE_ACTION_COUNT) if @tick_action >= $game_system.catb_after_action @tick_action = all_battle_members.each { |battler| battler.on_turn_end } @status_window.refresh $game_troop.increase_turn endendThey're the ways to set how turns work under DEFAULT_TURN = :tick && :action respectively, so "on turn end" of the whole battle should be triggered here. But in fact they just trigger on turn end for all battlers only but not the whole battle also, causing things triggered at "on turn end" of the whole battle won't be triggered at all.
- Autobattle flag and confusion bug:
Battlers simply won't make actions automatically under the above conditions.
Causes:
Consider the following part of method process_catb under class Scene_Battle(YSA Battle System: Classical AT
:BattleManager.action_list.each { |battler| battler.make_actions if battler.enemy? perform_catb_action(battler) if !@subject}
battler.make_actions causes battlers to make actions automatically. As it triggers only if battlers are enemies and actors aren't, actors won't make actions automatically.
Consider the attempted fix by Yami to this problem:
BattleManager.action_list
actor).each { |battler| battler.make_actions if (battler.actor? && !battler.input)}battler.input is initially nil, but after battler.make_actions it's not nil anymore, even after the action is executed. Battler.input remains not nil at the second and later times the battler attempts to make actions, causing failure to make actions. This explains why autobattle or confusion actions only take place once.
- Left arrow output bug:
The left arrow output should be going left in the list of living members, but is in fact the same as that of ESC.
Causes:
Consider the following part of method process_dir4 under class Window_ActorCommand(Yanfly Engine Ace - Ace Battle Engine):
call_handler
cancel)This causes left arrow(dir4) output to be cancel, being the same as that of ESC.
- Guard command bug:
Game crashes when the battle system isn't catb and the rightmost living member guards.
Causes:
Consider method command_guard under class Scene_Battle(YSA Battle System: Classical AT
:alias catb_command_guard command_guarddef command_guard BattleManager.actor.input.confirm = true catb_command_guard @status_window.draw_item(BattleManager.actor.index)end
When the battle system isn't catb, right after inputting guard command, the next actor(the right one)will be selected(you can observe this), even if it's the last member who guards. This is triggered by the original method command_guard, which is aliased as catb_command_guard. If it's the last member who guards, the next actor, which is nil, will be selected after calling catb_command_guard, causing BattleManager.actor to be nil. Game crashes when @status_window.draw_item(BattleManager.actor.index) is run with BattleManager.actor being nil.
- Confirm or cancel input bug:
Game crashes when a member confirm his/her/its action while he/she/it's dead.
Causes:
Consider the following parts of method on_enemy_ok, on_enemy_cancel, on_actor_ok, on_actor_cancel, on_skill_ok or on_item_ok under class Scene_Battle(YSA Battle System: Classical AT
:BattleManager.actor.input.confirm
Code:
@status_window.draw_item(BattleManager.actor.index)When a party member dies, the respective BattleManager.actor becomes nil. Game crashes when either of the above parts of code is run with BattleManager.actor being nil.
- Command window bug:
Neither party nor actor command window shows up when they should, causing the game to freeze.
Causes:
Consider method update_message_open under class Scene_Battle(YSA Battle System: Classical AT
:alias catb_update_message_open update_message_opendef update_message_open catb_update_message_open if !$game_message.busy? && @status_window.close? && !$game_troop.all_dead? && !$game_party.all_dead? @status_window.open endend
After displaying text in battle, only the status window is opened, when party window and actor window are also supposed to open while they're active.
- Party member change bug:
Game crashes due to adding or removing party members.
Causes:
Removing members -
Consider the following part of method process_catb under class Scene_Battle(YSA Battle System: Classical AT
:@f_actor_index = if !@f_actor_index || @f_actor_index < || @f_actor_index + 1 > BattleManager.action_list
actor).sizef_actor = BattleManager.action_listactor)[@f_actor_index]@f_actor_index += 1 if (@f_actor_index + 1) < BattleManager.action_listactor).size && f_actor && f_actor.input && f_actor.input.item && f_actor.input.confirmf_actor = BattleManager.action_listactor)[@f_actor_index]if f_actor && f_actor.input && !f_actor.input.confirm && (!BattleManager.actor || @status_window.index != BattleManager.actor.index) && !@actor_command_window.active && !@party_command_window.active BattleManager.set_actor(f_actor.index) @status_window.select(BattleManager.actor.index) @actor_command_window.setup(BattleManager.actor) @actor_command_window.showendBattleManager.action_list
actor) is the list of actors that can make or are already making actions at the moment.Consider the following part of method clear_catb under class Game_Battler(YSA Battle System: Classical AT
:BattleManager.delete_catb_action(self)
delete_catb_action(self) is the only method that deletes elements in BattleManager.action_list
actor), and clear_catb is the only method that calls delete_catb_action(self). As removing members won't immediately trigger clear_catb, BattleManager.action_listactor) still includes the removed members if they can make or are already making actions right before removal. As member's index(f_actor.index) are nil when they've removed, nil is passed to method set_actor under module BattleManager when the code BattleManager.set_actor(f_actor.index) is run:class <<selfdef set_actor(actor_index) @actor_index = actor_indexendend
This sets @actor_index as nil. Game crashes when the following method self.actor under module BattleManager is called by running the code @status_window.select(BattleManager.actor.index):
def self.actor @actor_index >= ? $game_party.members[@actor_index] : nilend
Adding members -
Consider the following parts of method input under class Game_Actor(Yanfly Engine Ace - Ace Battle Engine):
if @actions.nil? make_actions @action_input_index = 0end
Code:
@actions[@action_input_index].nil?This is where the game crashes when new members are added after the start of the battle, due to @action_input_index being nil as no value is assigned to it. This method sets @action_input_index to 0 only if @actions is nil.
Consider the following part of method clear_actions under class Game_Actor:
@action_input_index =
This is one of the only 2 instances(the other one is the above) where a value is assigned to @action_input_index.
Consider the following part of method initialize under class Game_Battler:
@actions = []
This defines @actions as an empty array.
Consider the following part of method make_actions under class Game_Battler:
@actions = Array.new(make_action_times) { Game_Action.new(self) }
This assigns an array of actions with the size make_action_times to @actions.
When new members are added after the start of the battle, clear_actions and initialize won't be called so their @actions are nil. When they can act, their @actions are defined as an array of actions with the size make_action_times. input is called after this but now their @actions aren't nil anymore, while clear_actions is still not called yet. No values are assigned to @action_input_index at all in the above process, causing the game to crash when @actions[@action_input_index].nil? is run with @action_input_index being nil.
- Action Times+ bug:
Action times is always 1 no matter how to user set the Action Times+. This is hardcoded in YSA Battle System: Classical ATB.
Causes:
Consider the method make_action_times under class Game_Battler(YSA Battle System: Classical AT
:alias catb_make_action_times make_action_timesdef make_action_times BattleManager.btype?
catb) ? 1 : catb_make_action_timesendmake_action_times always returns 1 when the battle system is catb, causing Action Times+ meaningless.
- Enemy action picking bug:
Enemies pick new actions every frame, even while charging, causing them to have a chance to pick new actions and alters the charge rate before finish charging the original ones.
Causes:
Consider the following part of method process_catb under class Scene_Battle(YSA Battle System: Classical AT
:BattleManager.action_list.each { |battler| battler.make_actions if battler.enemy? perform_catb_action(battler) if !@subject}
battler.make_actions causes enemies to pick actions. As it triggers every frame(even while charging, same below) due to process_catb being triggered every frame, enemies pick actions every frame and alters the charge rate before finish charging the original ones.
- Dying enemy selection bug:
Game crashes when enemies die while being selected.
Causes:
Consider the following part of method update under class Window_BattleEnemy(Yanfly Engine Ace - Ace Battle Engine):
enemy.sprite_effect_type = :whiten
When enemies die, enemy becomes nil. Game crashes when the above code is run(triggered by selecting enemies) with enemy being nil.
Video
You may've noticed a bug at 1:17 of the video, which is Isabelle picking actions before her atb bar is full. This is merely a compatibility issue with Yanfly Engine Ace - Party System Add-On: Command Party.
