- call SetVarObject((GUIDSTRING)_Source, (STRING)_VarName, (GUIDSTRING)_Object)
Sets the value of the variable %<_Varname> to _Object, if the variable exists and is of the right type.
- The variable has to be global. The _Varname does not include the prefix % that is used for global variables in behaviourscript. E.g. a variable that is called %Variable in behaviourscript would simply be Variable for the purposes of this call.
