Re: IK FK switch with an On Selection Event

[André Adam <a_adam(at)49games.de>]

Nope, that's pretty much it. The property holds a piece of script code 
as a string (most simple case possible: a single command), which gets 
executed using the eval method.

var oProp = ActiveSceneRoot.AddProperty("CustomProperty", false, 
"StringCommand");
oProp.AddParameter3("paramCommand", siString, "LogMessage(\"Hi!\")");
eval(oProp.Parameters("paramCommand").Value);
