Title: code problem
Post by: Bill_O on February 26, 2019, 09:32:45 AM

The attached code is giving me a nil value on the first line.
What do I have wrong.

You didn't declare inst.  Try this:

local inst = mc.mcGetInstance()
local hreg=mc.mcRegGetHandle(inst, 'ESS/Encoder_0')
local EncRawVal=mc.mcRegGetValue(inst, hreg)
scr.SetProperty('droEncRep2', 'Value', tostring(EncRawVal))

mc.mcRegGetValue only uses a single parameter...hreg
