[SOLVED][Crowds] Accessing agentcliplength in CrowdTrigger Node?

[bentraje]

Hi,

How do I use the `agentcliplength` in CrowdTrigger Node?
It returns 0.0 value instead of the actual clip length.

Pelase see reference below

You're blurring the concept of scope. The variable float len is not an attribute, it's a local variable that falls out of scope when the wrangle terminates. Thus when you reference the attribute, it defaults to 0.

Try:

f@len = agentcliplength(0,0,"walk");

Thanks for the response.
Nice catch on the f@len.

I revised the VEX with the len attribute but it still gives me a 0 value.
Are there any other areas I should look into?
My main concern would be the (0,0, "walk")
Considering that the crowd trigger does not have an upstream node. So maybe that's why its nofetching a value?

Try passing the direct path instead of 0.

string handle_path = "op:/obj/geo1/dopnet1:crowdobject1/Geometry";
float len = agentcliplength(handle_path, @id, "walk");
f@attr_len = len;

Thanks. It now works as epected! Didn't know you can actually refer an object through a string in VEX rather than adding it on on a parameter/through expression.
I guess the keything is adding those colon :
