Hallo Agura,

Beim Maker haben die "*-Tiles" leider immer einen fixen Z-Wert, der so eingestellt ist, dass er über dem Charakter steht.
Ich wollte dir gerade ein Script schreiben, welches den Z-Wert anhand der Position/Größe anpasst, als ich merkte, dass es da etwas gibt (gut, dass ich immer selbst google, bevor ich loslege):

# ▼ Moby's Script System - Correct Sprite Display V1.0
# -- Last Updated: 2013.01.26
#
#==============================================================================

$imported = {} if $imported.nil?
$imported["MSS-Correct_Sprite_Display"] = 1.0

#==============================================================================
# ▼ Updates
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# (by brushfe) Tall events interact better with other tall events

#==============================================================================
# ▼ Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script corrects how sprites will be displayed, to prevent errors
# happening when the sprite is higher than 32px and the tile above it is set
# to star passability.
#
#==============================================================================
# ▼ Instructions
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# To install this script, open up your script editor and copy/paste this script
# to an open slot below ▼ Materials/素材 but above ▼ Main. Remember to save.

#
# This script is Plug and Play.
# It automatically checks if the Sprite is bigger then 32px and adjust the
# tiles around that sprite accordingly.
# If you're using Anaryu's Particle Engine (ported by Yami)
# there won't be any issues.
#
#==============================================================================
# ▼ Compatibility
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script is made strictly for RPG Maker VX Ace. It is highly unlikely that
# it will run with RPG Maker VX without adjusting.
#
#==============================================================================
#
#==============================================================================
# ▼ Known Issues
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# Really wide character sprites still are sometimes drawn behind tiles they
# should be in front of.

Sollte etwas nicht funktionieren, gib mir gerne Bescheid. Bei Zeiten kann ich mir das Script anschauen und anpassen, falls nötig.
