MultiJoints + Scripting

[tsn]

Is there a certain reason why MultiJoints aren't supported by RF's Python interface? It's not even possible to switch "Simulation" from "Inactive" to "Active".

Hi Thomas,

just an advice- recently, I had some troubles keying/ switching "Simulation" (thus not by script but by hand) but everything was working fine when doing this on "Dyn Motion", intead,

Thanks for the tip. Unfortunately this won't help with MultiJoints, since they're obviously not implemented in the Python API, but I hope this will be changed with the next patch.

Hi Thomas,

for that specific purpose, you can use an XML import workaround:

Code: Select all

import os
import tempfile

def setMultiJointSimulation( mjname, status ):
	# Compose XML code
	xmlcode = '<?xml version="1.0" encoding="UTF-8"?>'
	xmlcode += '<!DOCTYPE rfxml><rfxml version="0.2">'
	xmlcode += '<nodes>'

	xmlcode += '<node name="'
	xmlcode += mjname
	xmlcode += '" class="MultiJoint"><parameters>'
	
	xmlcode += '<param name="Simulation"><enum_val><string>'
	xmlcode += status
	xmlcode += '</string></enum_val></param>'
	
	xmlcode += '</parameters></node></nodes></rfxml>'

	# Save to temporary file and import
	tmp = tempfile.NamedTemporaryFile(suffix=".xml", delete=False)
	tmp.write( xmlcode )
	tmp.close()

	scene.importFromXML(tmp.name,False,True)

	os.remove(tmp.name)
	scene.paint()


# Example
setMultiJointSimulation( "MultiJoint01", "Inactive" )

Hope that helps until MultiJoints are finally added for scripting.

Hi Alex,

Many thanks for this clever workaround. I've tested it and it works great.
