Are PyConstraints (“Script”) constraints implemented?
Not yet. Some things have changed internally in the PyAPI backends which mean the old ways won’t work without some serious modification to certain parts. But then, even if I did go through all the work to port PyConstraints to work with the new backends, the overall format would seem terribly out of place in the modern integrations of Python into Blender. So really, they haven’t been restored yet as there are some lingering issues that need to be resolved first. Of particular note are: 1) Local constraints per file vs “builtin” to Blender as if they were native. 2) Technical issues arising from taking either side. (RNA-registration voodoo and where to store this stuff are big problems). Doing a hybrid approach is even worse in terms of maintainability… Deferred until a later date when these issues become clearer.
