Hi, 

You will have to set the pts and meshes inputs as a list, otherwise the algorithm is no capable of iterating.

Best,

Hi Mario~ Thanks for your quick reply!!

Could you please kindly show me what does it mean of "pts and meshes inputs as a list" 

Do you mean multiple pts and meshes? It does not seems to work when I connect the input with point or mesh as sort of aggregation. Sorry as I'm a beginner. Many thanks!! :)

It would be invaluable support if you can show me an example with this python example. Never thanks enough!!! :)

check the snapshot. you need to declare what king of data structure you input in the script..(item, list, tree)..

I am attaching the working def.

This is no easy task for a beginner though make sure you understand this and refer to other discussions on how to set the input values on custom scriptable components in Grasshopper.

Best,

M

Hi Marios,

I know this is from a long time ago. Wondering if you might help at all.  I understand the data needs to be in a list. I am however getting an error in a line of code that doesn't seem to exist?  I'v attached the error and the files. Any advice would be much appreciated.

I have no idea what you want to do with this script.

I fixed it but I have also posted a more resilient agent system using python on Github a while ago.

Thanks Mario~ It is working now.

And my another inquiry is that can you give me a direction to generate a variety density of blob meshes under node points of the trajectory lines like the below link? I believe you already have seen it.

http://www.algorithmicdesign.net/bartlett/encoded_2012/agentSense/a...

Basically, the agent lines generated through this script does not have well fitted intersection points, I have no idea how to make sort of skeleton typed blobs-should be connected with WB. I've tried with "exoskeleton" and "ts-pipe", but both of them does not seem to work like the link since generated agent lists do not have node points.

Many thanks for continuing support!!!
