Mini gra - Invaders
Tak jest, dobrze widzicie, mini gra, którą można odpalić w grze na RPGVXAce. Klasyczne wciągające nawalanie na ekranie.
Prosta strzelaninka, gra typu SHMUP, którą można odpalić za pomocą wywołania skryptu.

Zamysłem autora było stworzenie prostej gry, z prostymi zasadami. Losowi przeciwnicy, którzy losowo atakują statek bohatera. Wiadomo, z czasem zabawa nabiera tempa, przeciwnicy pojawiają się coraz częściej, coraz więcej, coraz bardziej agresywni, aż w pewnym momencie gracz nie posiada szans i przegrywa. Na planszy oprócz przeciwników można też spotkać apteczki, dodatkowe bronie i udoskonalenia.

Nie ma tego za wiele, ale zdecydowanie gdyby ktoś tworzył jakiś sklep ARCADE, gdzie bohater mógłby się rozerwać trochę, to skrypt jest w sam raz!

Cechy skryptu:
Za pomocą jednego polecenia zdarzenia - skrypt: SceneManager.call(Scene_Invaders), w każdej chwili posiadasz możliwość odpalenia mini gry Invaders.

Instalacja
Uruchomienie w programie edytora skryptów (F11). Odnaleźć na liście Main, i nad nim umieścić nowy moduł - wpisać nazwe: invaders, a następnie wkleić poniższy skrypt.

Uwagi:
Skrypt używa kilku grafik, które najlepiej jest pobrać z gry demonstracyjnej. Oczywiście nic nie stoi na przeszkodzie aby zamienić je na coś własnego.

#  Galv's Invader Mini Game
#------------------------------------------------------------------------------#
#  For: RPGMAKER VX ACE
#  Version 1.2
#  Thanks Ocedic for add-on ideas
#------------------------------------------------------------------------------#
#  2013-03-20 - Version 1.2 - added options for reset ratio and max gun powerup
#  2013-03-20 - Version 1.1 - added enemy types, new gun type, new powerup
#  2013-03-18 - Version 1.0 - release
#------------------------------------------------------------------------------#
#  A simple shooter mini game that can be played within Ace with a script call.
#
#  The game is designed to be simple. Enemies are random, they shoot random
#  lazors at you. Powerups are random. Slowly during the course of the game
#  the enemies spawn faster and faster until eventually the player will be 
#  overrun completely and die. A set time through the game, a reset powerup will
#  spawn. If the player manages to get it, they get another chance at more
#  points as it sets the spawn speed back to the start.
#  Variables are used for current score and high score which you can use in
#  your game to give your player bonuses for doing well or not.
#  
#  You'll need the demo for all the graphics (but feel free to create your own)
#
#  NOTE: This is intended to be simple for now. Please don't ask for add-ons
#  or improvements. I might improve it later but for now, it is what it is.
#------------------------------------------------------------------------------#
 
#------------------------------------------------------------------------------#
#  CONTROLS
#------------------------------------------------------------------------------#
#  Left and Right - moves left and right
#  Space/Z/Enter  - fire your lazor
#  ESC/X          - Leave the mini game
#  A              - Use held item (currently only nuke)
#------------------------------------------------------------------------------#
#  POWERUPS
#------------------------------------------------------------------------------#
#  Heath  - restores shields completely. If shields full, adds to an bonus bar
#  Zzzz   - resets enemy spawn rate to beginning (spawned only at a set time)
#  Nuke   - Can only hold one nuke at a time. Press A to destroy all enemies.
#
#  Lazors - Get lazors or increases number of lazors fired
#  Lazorball - Get lazorballs or increases number of lazorballs fired
#
#  NOTE: Obtaining weapons equips them or improves them if already equipped
#  NOTE2: Yes, I do know it's not spelled "lazor"
#------------------------------------------------------------------------------#

#  SCRIPT CALL:
#------------------------------------------------------------------------------#
#  SceneManager.call(Scene_Invaders)       # Starts the minigame.
