MiniScript v1.5 is now live in the Asset Store! This includes all the improvements to the language itself (detailed here), plus a host of small improvements to the code editor, which is available only via this asset. Full source code is included.
If you want to give it a try, check out the web demo and Robo-Reindeer Rumble, both of which were freshly built with the latest version of the asset.
This is a recommended (and free!) upgrade for all existing owners of the asset.
Please note: while MiniScript itself doesn't require TextMeshPro — and even the code editor could be made to work without it, in principle — the demo scenes all use it. And it seems that Unity gets quite confused if you import the asset before it has the TMPro classes to resolve against. So for best results, please import the TMPro Essentials before importing this asset.
Have fun, and make cool stuff!
