Im playing game called Spiral Knights I launch .jar file with this batch command and portable java

CD "App"
"E:\Programy\Portable Apps Platform\PortableApps\CommonFiles\Java64\bin\java.exe" -Xms3G -Xmx3G -XX:+UseParallelGC -XX:+UseParallelOldGC -jar getdown-pro.jar .
exit

My question is does any argument or parameter (or whatever its called) exist to start game in maximized window? Not full screen just maximized

I am 2nd hour googling and trying stuff i found and stuff like

start /max or window=max

does not work

As i understand it all that arguments/parameters like start /max or window=max are going to affect CMD window and not java app and thats why they dont work but all that

-Xms3G -Xmx3G -XX:+UseParallelGC -XX:+UseParallelOldGC

affect java app so is there something like that for window maximized?

  • Exactly since this is the game im talking about But i believe it could also be minecraft.jar Since i seen same arguments/parameters are used to launch each of them when i find any script for Spiral Knights or Minecraft

    You need to make it portable. But i think you mean launching it with batch script Here spiralknights.com on right side under play now you have download button. Just download and then install it and you should get shortcut to SK on your desktop. Right click it > properties > open folder/file location. Here all you need is batch script with ( More or less you need to adjust java path): Where if you have java installed then "%ProgramFiles%\Java\jre7\bin\java.exe" -Xincgc -Xmx1G -jar getdown-pro.jar .

    Or if you want to actually make it portable you will need portable java i get mine from here portableapps.com/apps/utilities/OpenJDKJRE64 And then you will need to alter the pat for batch script

    I think spiral knights installs to app data so after installation you can open any folder and type %APPDATA% into address bar and hit enter and you should see Spiral Knights folder there which you can move to desktop or wherever
