#Basic Window Resizer v1.1
#----------#
#Features: Allows you to resize the window to whatever size you like! (This is not
# like Graphics.resize, this will scale to fit)
#
#Usage: Script calls:
# Window_Resize.r(width, height) - Self-explanatory
# Window_Resize.f - fits the game window to monitor size
# Window_Resize.full - switches to full screen unless already fullscreened
# Window_Resize.window - same as full but opposite
# Window_Resize.toggle - toggles between full and window
#
#No Customization
#

Like i said im a complete noob at scripting, could someone change that for me in this script

I'm still in my 1st week of using rpg maker vx ace, so i still try to get a hang of it. Where exactly do i find that feature ?

I tried it and i get an error, anyway technically i think that sounds wrong. Because it has to work before i run the game and not triggered while i enter a map right ?
