Workspace folders

VSCode multi-root workspace can be used to "join" your mod folders as they get loaded into the game.

The order of how files are being searched is now determined by how the workspace folder appears in explorer tab. The last folder is searched first.

Function hover

It can simulate your .IWD files - their file name determines which files gets loaded first in the game.

For example, this is typical setup:

  • raw
  • mod1
  • mappack

From game perspective, it could represents these files:

  • iw_00.iwd - iw15.iwd (original game files for CoD2)
  • z_mod1.iwd
  • zzz_mappack.iwd

The alphabetical order of .IWD is important to correctly replace original files. The order of the workspace folders must be the same!



Code actions

Code actions - include folder for file references

Function hover

Code actions - ignore missing files

Function hover



GSC Files

Visualization of replaced (unreachable) files.

When GSC file is replaced by another GSC file in multi-root workspace because of the same game path, the code in text editor is shown as semi-transparent (unreachable code)
Example:

Function hover



Other

Status bar

Allows quickly change the targeted game or open settings.

Function hover

Side panel

GSC side panel with "Workspace", "File" and "Other" views. It shows information about workspace setup, parsed GSC files and available commands to run. In future version it will allow to change settings more interactively.

TODO list

Priority

  • Add custom global include list of GSC function
  • Support for default function parameter value - supported in newer COD games
  • Support for 'chilthread' and 'call' keywords - supported in newer COD games
  • Improve auto-suggestion for files
  • When renaming GSC file, ask for reference update in other GSC files

Non priority

  • Code action - implement unknown function
  • Add .csc files (client side scripts)
  • Parser for .menu files
  • Integrate list of built-in functions for CoD4
  • Improve detection of variable types - now it's detected only by explicitly assigned constant value
  • Show available string constants for notify waittill waittillmatch endon in completion item provider
  • Check for unreachable code
  • Implement "Go to definition" for variables
  • Implement some kind of JSDoc comments to improve function and variable description
  • Implement rename variable functionality
  • Detection of undefined variables

Install

This extension is available through Visual Studio Marketplace.
