Class Description

Utility class for working with pointers and references in Python.

Many of Maya's API methods require that one or more of their parameters be passed as pointers or references. Their return values, too, can be pointers or references.

In Python parameters of class types are passed by reference but parameters of simple types, like integers and floats, are passed by value, making it impossible to call those API methods from Python. The MScriptUtil class bridges this gap by providing methods which return pointers to values of simple types and which can extract values from such pointers. These pointers can also be used wherever an API method requires a reference to a simple type or an array of a simple type.

For example, MTransformationMatrix::setShear() requires as its first parameter an array of three values of simple type 'double'. To call setShear() from Python requires using MScriptUtil to create the array of doubles:

matrix = maya.OpenMaya.MTransformationMatrix()
util = maya.OpenMaya.MScriptUtil()
util.createFromDouble(1.0, 2.0, 3.0)
ptr = util.asDoublePtr()
m.setShear(ptr, maya.OpenMaya.MSpace.kObject)

Similar code is required to get the shear value using MTransformationMatrix::getShear(), but MScriptUtil methods must also be used to extract the returned values from the array:

util = maya.OpenMaya.MScriptUtil()
util.createFromDouble(0.0, 0.0, 0.0)
ptr = util.asDoublePtr()
matrix.getShear(ptr, maya.OpenMaya.MSpace.kObject)
shearX = util.getDoubleArrayItem(ptr, 0)
shearY = util.getDoubleArrayItem(ptr, 1)
shearZ = util.getDoubleArrayItem(ptr, 2)

If a method requires a reference or pointer to an enumerated value, use a pointer to a short int instead.

An MScriptUtil object keeps two sets of values internally: its initial values, and its working values. The initial values are those supplied either in the constructor or by calling one of the object's create*() methods. The working values are those to which the as*Ptr() methods return pointers.

Each time a create*() method is called it completely replaces the old initial values with the new ones. The as*() methods (asInt(), asFloat(), etc) but not the as*Ptr() methods, all return the first internal value, converted to the appropriate type.

Each time an as*Ptr() method is called it completely replaces the old working values with new ones of the requested type and initializes them from the initial values. If the type of the working values does not match that of the initial values then appropriate conversions are done. For example, if you have initialized an MScriptUtil object with four doubles via a call to createFromDouble(), then a subsequent call to asBoolPtr() will allocate space for four boolean working values and initialize them from the initial values by converting non-zero values to true and zero values to false.

The separation of initial and working values means that changes to the working values will not affect the initial values. For example, if you pass the pointer returned by asBoolPtr() to an API method which changes the working value it points to, the object's initial value will remain unchanged and its asInt() method will continue to return the same value as it did before the API call.

The number of working values returned by the as*Ptr() methods will match the number of initial values. Thus it is important that you provide a sufficient number of initial values before calling an as*Ptr() method. If no initial values are provided in the MScriptUtil constructor and none are subsequently supplied by calls to the create*() methods, then the pointers returned by the as*Ptr() methods won't have room to store even a single value, which will likely lead to errors.

As already noted, each call to one of an object's as*Ptr() methods completely replaces the old working values with new ones, thus rendering invalid any pointers previously returned by that object. This means that if you need multiple pointers for a single API call, you will need multiple MScriptUtil objects. MFnMesh::getUV() provides an example of this:

meshFn = maya.OpenMaya.MFnMesh(node)
u_util = maya.OpenMaya.MScriptUtil(0.0)
u_ptr = u_util.asFloatPtr()
v_util = maya.OpenMaya.MScriptUtil(0.0)
v_ptr = v_util.asFloatPtr()
meshFn.getUV(0, u_ptr, v_ptr)
u = u_util.getFloat(u_ptr)
v = v_util.getFloat(v_ptr)

When an MScriptUtil object is destroyed any pointers to its data immediately become invalid. Thus the following code will fail because the MScriptUtil objects created by getUVPtrs() will go out of scope and be destroyed when the function returns, rendering the pointers it returns invalid:

# WRONG!
def getUVPtrs():
    u_util = maya.OpenMaya.MScriptUtil(0.0)
    u_ptr = u_util.asFloatPtr()
    v_util = maya.OpenMaya.MScriptUtil(0.0)
    v_ptr = v_util.asFloatPtr()
    return [u_ptr, v_ptr]
uvPtrs = getUVPtrs()
meshFn.getUV(0, uvPtrs[0], uvPtrs[1])

To work, getUVPtrs() would have to preserve the MScriptUtil objects in some way, such as passing them back to the caller as well:

# RIGHT!
def getUVPtrs():
    u_util = maya.OpenMaya.MScriptUtil(0.0)
    u_ptr = u_util.asFloatPtr()
    v_util = maya.OpenMaya.MScriptUtil(0.0)
    v_ptr = v_util.asFloatPtr()
    return [(u_ptr, u_util), (v_ptr, v_util)]
uvPtrs = getUVPtrs()
meshFn.getUV(0, uvPtrs[0][0], uvPtrs[1][0])

This class is admittedly cumbersome to use but it provides a way of building parameters and accessing return values for methods which would not otherwise be accessible from Python.
