How to make the game LAUNCH in full screen

[Dark Jaguar]

I've seen plenty of comments about how to switch the game to full screen after the fact, but is there a way to configure the game to ALWAYS launch in full screen?

F4 dude

Unfortunatley it does not save this. Is there a configuration option that makes it launch in full screen, so I don't have to bother every time?

Uh, i don't think there really IS a way..

It doesn't effect anything negatively in my experience, and it allows you to tab out easily and do other things should you need too.

If you don't find a way I hope you can still enjoy it.
At this moment I don't think you can.

It looks like a design choice.

I need to know how to do this if it IS possible. I'm recording my Undertale gameplay and I'm at the Omega Flowey fight where when the game launches, it has the edited intro with cracked screen. Anyway, I need to record that and I can't have the video small for a sec and then fullscreen.

Damned if you do, damned if you don't. Another ressurected thread. I just lazily googled it. Here is a video. I don't really care about this thread anymore. https://youtu.be/RuNU8Z7hpdU

-------------- Bad mood right now.

While I appreciate you taking the time, this isn't what either that poster or I were asking for. We were just wanting a setting to make Undertale start full-screen rather than start windowed. Sure, it can be set to full screen with the press of a button, but it'd be nice to have it full screen right from the start without needing to do that for a number of reasons.

I apologize for my earlier post. I hope you find a solution and that they update it to allow it to start in fullscreen for you and others someday.

You can put it into the launch option here: https://support.steampowered.com/kb_article.php?ref=1040-JWMT-2947

I'm spreading the word because none of the threads seem to answer this question

[SkaFiend]

the thread is quite old, but I'll leave this poweshell script here:

$ps = Start-Process -PassThru -FilePath "f:\Games\Undertale\UNDERTALE.exe" -WindowStyle Normal

$wshell = New-Object -ComObject wscript.shell

$wshell.AppActivate('undertale')
Sleep 3
$wshell.SendKeys('{F4}')

$ps.WaitForExit()
$ps.Dispose()

and this one is autohotkey script to remap your buttons. delete "SendMode Input" if you experience any button lags:

#NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases.
; #Warn ; Enable warnings to assist with detecting common errors.
SendMode Input ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory.
#SingleInstance Force

#IfWinActive, ahk_exe UNDERTALE.exe

w::Up
s::Down
a::Left
d::Right

#IfWinActive

If anyone is checking this out since the release of AutoHotKey 2.x I updated the script, added mouse controls, and gave it a suspend command that allows you to use they keyboard and mouse normally if you leave the game for a moment. Really just a compilation of scripts I found around the internet and messed around until it all worked right.

A_HotkeyInterval := 1000 ; Prevent Script from bugging out when you press the keys too quickly in succession.
#SuspendExempt ; Prevent Suspend key command from being suspended
Esc::ExitApp  ; Exit script with Escape key
^!s::Suspend -1 ; Suspend script with Ctrl+Alt+S
#SuspendExempt False
w::Up
s::Down
a::Left
d::Right
LButton::z
RButton::x
MButton::c

Furthermore, I wrote a batch script that runs both UNDERTALE.exe and the AutoHotKey script simultaneously. Here's that:

start "Start UNDERTALE" "C:\Program Files (x86)\Steam\steamapps\common\Undertale\UNDERTALE.exe"
start "Start AutoHotKey" "C:\Program Files (x86)\Steam\steamapps\common\Undertale\Undertale.ahk"
@echo on

Finally, here is the launch argument for Steam that redirects the launcher to the .bat file instead of the EXE file:

"C:\Program Files (x86)\Steam\steamapps\common\Undertale\UNDERTALE.bat" ; killall -9 AutoHotkey %command%

The only downside seems to be that if you close the game via the X button or through steam it won't kill the AutoHotKey script for some reason. However, holding Esc will kill both.
