Is there a way to use the current value of Accumulate Field as part of the input?

I'm almost positive that the answer is a pretty straightforward "no," but I was wondering if there was a way to use the total evaluated at the previous index as part of the input for the Accumulate Field node. Basically, I want to access the trailing value in the calculation. My actual goal was to try and position a series of points relative to each other/their previous positions without needing to have a series of chained Set Position nodes.

• Could you give an example for a formula, that you try to implement? Because, the trailing of the Accumulate Field node is always the last trailing + the Value-Input. Apr 28, 2022 at 20:19
• It's definitely possible I'm misunderstanding what the trailing value is, so maybe disregard that. Unless I'm completely wrong about how the node works, the value input is added to a running total that is being evaluated for each index, and I want to be able to use that total as part of the input formula (say I wanted the input at each index to be half of whatever the current total was).

• I think, it is not possible to use the previous value as an input for your current calculation. In my understanding, this would lead to a cycle in your node net. At least I did not finde a way, to prevent this cycle. Instead, taking your example, it would be best, to solve it differently. Let's say, y0 = 100 and you want to be y1=y0/2 and y(n)=y(n-1)/2. Then you could set y with the "Set Position" node by using the index with this formula: y = 100 * (0,5)^index. Apr 29, 2022 at 13:17
