Value range instead of creating each individual numbers
Hi all!
I am making a path based on data. I’ll have close to a 1000 X and Y points to place on that path once I get the full set. I am using the following expression to create said points using a JSON file with X and Y values. And I will eventually use Vegas or Trim Path or something of that nature to animate the path.
createPath(points = [[thisComp.layer("JSON")("Data")("Outline")("dataOutline 0")("X"),thisComp.layer("JSON")("Data")("Outline")("dataOutline 0")("Y")], [thisComp.layer("JSON")("Data")("Outline")("dataOutline 1")("X"),thisComp.layer("JSON")("Data")("Outline")("dataOutline 1")("Y")], [thisComp.layer("JSON")("Data")("Outline")("dataOutline 2")("X"),thisComp.layer("JSON")("Data")("Outline")("dataOutline 2")("Y")], [thisComp.layer("JSON")("Data")("Outline")("dataOutline 3")("X"),thisComp.layer("JSON")("Data")("Outline")("dataOutline 3")("Y")], [ETC...] inTangents = [], outTangents = [], isClosed = false)Now, is there a way to achieve that without having to create one line for each point with a value range or something of that nature? I have found a way to generate the 1000 lines I would need but I figured there might be a cleaner and probably less taxing on AE way to achieve it?
Or is there a totally different / simpler way you would go about this?
Thank you so much!

Can you post a chunk of your JSON file?

Sure can, here is an extract, and it will look like this another 1000 times.
{
"YEAR": 2021, "MONTH": 1, "DAY": 6, "HOUR": 16, "MINUTE": 32, "X": 632, "Y": 643 },
{ "YEAR": 2021, "MONTH": 1, "DAY": 6, "HOUR": 17, "MINUTE": 3, "X": 625, "Y": 642 }, -
I don’t know how efficient it will be, but you could tidy things up a bit like this:
p = [];
prop = thisComp.layer("JSON")("Data")("Outline");
n = prop.numProperties;
for (i = 1; i <= n; i++){
x = prop(i)("X");
y = prop(i)("Y");
p.push([x,y]);
}
createPath(p,[],[],false) -
Dan, you are a the best. It works, and it’s much more efficient than the method I was using. Thank you so much. 🙏
