+If you don't need a full-fledged IDE, you can use Visual Studio Build Tools instead. Taking [Visual Studio 2017 Build Tools](https://aka.ms/vs/15/release/vs_buildtools.exe) for example:

+   ```
+2. Set up a `postbuild.cmd` using the template from the repo.
+3. Use MSBuild in **x86 Native Tools Command Prompt** to build sfall:
+   ```
+   MSBuild.exe ddraw.sln /t:Clean;Build /p:Configuration=ReleaseXP /p:Platform=Win32

+Runs when using any skill on any object.

+This is fired before the default handlers are called, which you can override. In this case you should write your own skill use handler entirely, or otherwise nothing will happen (this includes fade in/fade out, time lapsing and messages - all of this can be scripted; to get vanilla text messages - use message_str_game along with sprintf). Suggested use - override First Aid/Doctor skills to buff/nerf them, override Steal skill to disallow observing NPCs inventories in some cases.
+
+Does not run if the script of the object calls script_overrides for using the skill.

+Critter arg0 - The user critter
+Obj     arg1 - The target object
+int     arg2 - skill being used
+int     arg3 - skill bonus from items such as first aid kits
+
+int     ret0 - overrides hard-coded handler (-1 - use engine handler, any other value - override; if it is 0, there will be a 10% chance of removing the used medical item)
