- Download the Guncho Mockup extension from here
- Unzip the file to a temporary folder.
- Within the Inform7 IDE, use the 'Install extension...' menu option to locate and install the extension.
- Within your project, include the following line:
Include the Guncho Mockup by Guncho Cabal.
Note that the extension allows you to develop, compile and test realms, however it does NOT support real-time events (i.e. no real-time event rules will ever get run while off-line) or multi-player mode (i.e. off-line, there will only ever be one PC - you - and none of the player joining or player leaving rules will get run). A couple of extensions that improve the mockup environment (real-time events, player joing rules, storage slot emulation, etc) are listed on Peskie's user page.
