【提问】如何更改图片的Z值 ? - Project1

# Fix Picture to Map

# Version: 1.0.2 [VXA]

# Author: modern algebra (rmrk.net)

# Date: 8 September, 2012

#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

#  Description:

#

# This allows you to set the position of a picture by the X and Y position

# of the map, rather than the screen, so that the picture won't move with you

# when the screen scrolls. Additionally, the script lets you set the Z value

# to show below characters, or even below the tiles or below the parallax.

#

# This script has no effect in battle and pictures there behave normally.

#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

#  Instructions:

#

# Paste this script into its own slot in the Script Editor, above Main but

# below Materials.

#

# To specify that a picture should be fixed to a map and not follow the

# screen, all you need to do is turn an in-game switch on before showing the

# picture. To specify which switch, all you need to do is change the value of

# SWITCH_ID at line 60. Alternatively, you can include the code [Fixed]

# somewhere in the name of the picture.

#

# For the fixed pictures, you also have the option of assigning it to grid

# coordinates instead of pixel coordinates. This means that if you wanted it

# to show up at (3, 5) in the map, you could set it to that directly instead

# of (96, 160). You can turn on this feature using another switch, again one

# which you choose by changing the value of COORDINATES_SWITCH_ID at line 63.

#

# To specify the layer of the tilemap (what shows above it and what shows

# below it), all you need to do is change the value of a variable. Which

# variable is also specifed by you by changing Z_VARIABLE_ID at line 69.

# The value to which that in-game variable is set at the time a picture is

# shown determines where the picture will show up. If the variable is set to

# 0 then it will be in its normal place; if set to -1, it will show below

# the tilemap but above the parallax; if set to -2, it will show below the

# parallax; if set to 1, it will show above all non-star tiles but star tiles

# and characters with normal priority; if set to 2, it will show above

# characters with normal priority but below characters with "Above

# Characters" priority. If set to any other value, the z value of the picture

# will be set to that directly.
