On line 36 we get the curve variables we're after: We can use that information to set the x-coordinates of the curve points so the Spline Wrap curves better reflect what's happening in our control spline. These are very useful if you're doing things with splines, in this script we're going to use it to help find how far along the length of the spline each of its points are. If the check fails the script returns before it gets into the more complicated stuff and saves us some time.Ī little bit later, from line 31 to 32, the script creates a SplineLengthData object. This isn't a foolproof test as any Python tag could start with that same code and hence trick this check, but nothing truly disastrous will happen in that case so it's good enough for our purposes. This gets all the tags attached to your spline, checks if they are Python tags, and if they are it checks if the Python code starts the same way as the Point Autorig code ("#pointrig tagcode"). It'll only work if your Spline Wrap has the Point Autorig's Python tag attached, starting on line 17: The main excitement happens in the applied Python tag, and I'll go through that a bit here.įirst up the tag's script does some tests to see if it should do anything. Check out the for loop from line 138 to see how that works.
This one has the added feature of being able to apply itself to any number of selected Spline Wrap objects with one click (it'll ignore anything that isn't a Spline Wrap). This script starts the same way as the Point Autorig, by checking your selected objects and attaching a Python tag with the rig's code. The Spline Wrap Autorig works by controlling the Spline Size and Spline Rotation curves in your Spline Wrap object, based on the size and rotation of the nulls in the Point Autorig.
