Data Recorder Reseting Python Code

[AndersDeleuran]

As suggested by @diff-arch above, you can likely simplify/better manage things by also recording the data using GHPython. Here’s some examples demonstrating the basic ingredients you’d need:

How to detect an update/change of a number?

That’s exactly what the script does. Perhaps it is more clear if we make a persistent list, instead of just one variable that we keep overwriting like in the examples above: [2018-08-24%2015_57_49-Grasshopper%20Python%20Script%20Editor] 180825_GHPython_PersistentLastCurrentValueCheck_01.gh (3.9 KB)

New list when data updates

This might not be exactly what you need, but should get you there if I understood the problem: [2018-09-22%2019_39_07-Grasshopper%20-%20180922_RotatingDataTree_GHPython_00] 180922_RotatingDataTree_GHPython_00.gh (6.5 KB) It basically records the input Data parameter into the first branch of a DataTree, while also rotating the branches each time it records.

Edit: Ah, sorry. You were posting a solution, need more coffee
