Uploading an EZ2 addon to Steam workshop with steamcmd

This guide will explain how to upload an addon to the EZ2 Steam workshop using Valve's developer tool, steamcmd

WARNING

This guide involves using developer Steam tools. NEVER log in to a program with your Steam credentials unless you have verified it is an authentic program from Valve. Do not download SteamCMD from any site other than Valve's hosting site. SteamCMD is a tool intended for developer use. It is not for casual users. Please use caution.

Do not upload any content to the workshop from another game, otherwise copyrighted, or which you do not have license to use. If you use content from another mod creator, you must have their permission to reupload that content.

Content may be removed from the Steam workshop for any reason.

This Steam workshop community guide is based on the guide for workshop addons for FIREFIGHT RELOADED.

Check out their guide here: https://steamcommunity.com/sharedfiles/filedetails/?id=648007467

This guide can be used for EZ2 as well, as long as you update the appid in the VDF file to point at Entropy : Zero 2's appid (1583720) instead of FIREFIGHT RELOADED's.

Prerequisites

• Install SteamCMD
  
  • https://developer.valvesoftware.com/wiki/SteamCMD
• Have an original addon ready to upload
  
• A text editor such as Notepad++, VIM, VS Code, etc

Create VDF file

1. Store all the content for your addon in a directory for the addon. This would include folders like "models", "maps", "sound", etc. Ensure only content which is part of your addon is in this directory. At this time it is not recommended to package addons as VPKs, although that may change in the future.
   
2. In the parent directory of your addon directory, create a text file in your text editor of choice. Save the file with the extension ".VDF". This will be your addon file.
   
3. Follow the format below. Make sure to replace contentfolder with your directory. You may need to use escaped backslashes (\\) in your directory path.
   
4. Make sure that the appid is 1583720 for Entropy : Zero 2

"workshopitem"
{
	"appid"		"1583720"
	"publishedfileid"		"0"
	"contentfolder"		"Path\\To\\Your\\Folder"
	"previewfile"		""
	"visibility"		"0"
	"title"		"Example addon"
	"description"		"This addon is an example for the Steam workshop guide"
	"changenote"		"Version 1.0.0"
}

Upload the addon with SteamCMD

Open the directory where your addon and VDF file are saved in a terminal. For this guide, I used Powershell. Make sure to change directory into the correct directory.

Run this command to start steamcmd:

./steamcmd.exe

Once in steamcmd, use the 'login' command to login. You will need to enter your username and password. Remember to be careful where you are running this and make sure you are using SteamCMD downloaded from Valve.

SteamCMD may prompt you for a Steam guard authenticator code.

login username password

Finally, use the command 'workshop_build_item' to upload your item. Replace "example.vdf" with the name of your .vdf file from the previous step.

workshop_build_item example.vdf

If all goes well, your addon will be uploaded to the workshop. You can exit steamcmd with the 'quit' command.

quit

Good luck, and have fun workshopping!

[CSecretive]

Will there be a publisher or something like that? An exe in bin folder?

[CSecretive]

My sound addon doesnt work. I did the correct sound replacement repository and it doesnt do anything.

Well i guess ill never be abble to upload my hd textures ( ai upscale ) ... its ready but i just cant get to make cmd publisher connect to my account. i tried all day again by trying different things from the offical valve page.. welp if people want it just send me a friend request i guess so i can give you the link to it. until i find a way to make cmd work for me if it ever happen lol

[Dany 117]

yep i did that exactly this way, still say the same thing, i even tried other way of doing it by looking on the official valve page and again... so does cmd has to be installed in a particular place or it dosent matter

[1upD]

Are you sure you're entering "login <your_username> <your_password>"?

[Dany 117]

idk why but i keep getting invalid password, and i know im doing the right one, i even changed it same result, any ideas
