Reference parameter value from path reference to another node

[bobbybob]

I have a node inside an asset. The asset has a parameter that references a camera. The node inside the asset needs the "resx" parameter value of the camera. I need to use the assets camera reference to get the "resx".

I tried this:

ch(chs("../cam")+"/resx")

but I can't get it to work... How is this done correct?

ch(strcat(chs("../path_to_cam"),"/resx"))

Using the strcat function to combine strings.

@Fenolis Thanks. Ahh I see. We need to use the absolute path to the camera from the first reference (asset) is it possible to use a relative path instead?

/obj/cam1 -> ../../cam1

The reason a relative path didn't work with the expression is because when using the function chs("../path_to_cam"), if the path is relative, it doesn't account for the nesting depth difference between the parameter you are referencing and the parameter trying to pull the value. You can, of course, figure out the correct nesting depth of your parameter and concatenate the right number of "../" as a prefix to the path's string. In this situation I would recommend sticking with absolute path if possible.
