Checkpoints and Continues (VX)
Version: 1.0
Author: Zylos
Date: March 16, 2011
Description
This script allows the game creator to easily set up checkpoint spots for the player to respawn to after the party has been defeated. The creator simply calls this script in an event on the map (such as during a map transfer or after an important cutscene), then when the player reaches what would normally be a game over, they will be allowed to continue the game from the exact spot marked by the creator. Additionally, the creator may allow the player a set number of continues or lives before it is game over for good.
Features
- Lets you easily set up game checkpoints with events.
- Allows the player to continue from the last checkpoint after being defeated.
- Capable of using either unlimited continues or a set quantity before game over.
- Very customizable and easy to follow.
Screenshots
Instructions
- Place this script in the materials section, above Main.
- Check the script settings in the editable region of the script (below the instructions) to make sure they are to your needs. Continues_Enabled determines whether the player is allowed to continue from a checkpoint after being defeated. Number_Of_Continues is the number of times the player is allowed to try again from a checkpoint (set a negative number for unlimited continues). Continue_Graphic is any image you wish to use for when you are allowed to continue instead of getting a final game over. Return_To_Title determines whether the player returns to the title or whether the game should shut down if the player chooses not to continue after being defeated.
- Use the script command in an event and type in "checkpoint" without the quotes. This will create a checkpoint at that exact point. Checkpoints are also automatically created upon the start of a new game, saving the game, and loading a save file.
- For a better visual, you might also want a specific graphic to use instead of the regular game over screen. Add your screen to your games system folder and change the Continue_Graphic to the file's name for it to replace the game over screen when the player is allowed to continue. I've made the following screen for anyone to use if they want to:

# Continues_Enabled determines whether the player is allowed to continue or
# not when they have reached a gameover screen. In essence, it determines
# whether this script is turned on or off. This may be turned off in the
# game by calling "$game_system.continues_enabled = false".
#============================================================================
Continues_Enabled = true
#============================================================================
# Number_Of_Continues sets the number of times the player is allowed to
# continue from a checkpoint before finally getting a gameover. Setting
# this to a negative number lets the player continue without a limited
# number of continues. You may add to this number ingame by calling
# "$game_system.lives += 1" and subtract similarly.
#============================================================================
Number_Of_Continues = -1
#============================================================================
# Continue_Graphic is the image used to replace the gameover screen if the
# player is allowed to continue from a checkpoint. If the picture does not
# exist in the games system folder, then the default gameover screen will
# be used. Editable with "$game_system.continue_graphic = 'imagename'".
#============================================================================
Continue_Graphic = "Continue.png"
#============================================================================
# Return_To_Title determines whether the player should return to the title
# screen if they choose not to continue from a checkpoint, or whether the

# can do battle before the title screen comes up. Editable with
