Mplug Attribute Type

[mayapower]

Hi,

MPlug plug = nodeFn.findPlug(shaderAttributes[k],&status);

How to find what type of attribute it is? i.e float, float3, string, double3 or whatever

Thanks

MPlug::attribute().apiType()

depending what's returned, pass into one of

MFnUnitAttribute MFnTypedAttribute MFnNumericAttribute MFnMessageAttribute MFnMatrixAttribute MFnLightDataAttribute MFnGenericAttribute MFnEnumAttribute MFnCompoundAttribute

then use those to determine kFloat, kLong etc.

Could you please give me a small example.

Thanks.

CODE
  MPlug mpTest;
  if (mpTest.attribute().apiType() == MFn::kNumericAttribute) {
    MFnNumericAttribute mfnaTest(mpTest.attribute());
    if (mfnaTest.type() == MFnNumericData::kDouble) {
      // ...
    }
  }

It's satisfying the condition:
if (plug.attribute().apiType() == MFn::kNumericAttribute) {

but after that it's not satisfying any of the attribute type condition.

Here is the Code

MPlug plug = nodeFn.findPlug(shaderAttributes[k],&status);
if(MStatus::kSuccess == status){

				//All the Numeric Attributes = int,float,float3,double,double3
				if (plug.attribute().apiType() == MFn::kNumericAttribute) {
					MFnNumericAttribute mfnaTest(plug.attribute());

					if (mfnaTest.type() == MFnNumericData::kBoolean) {
						bool value;
						plug.getValue(value);

					}

					if (mfnaTest.type() == MFnNumericData::kLong) {
						double value;
						plug.getValue(value);
						
					}
											
					if (mfnaTest.type() == MFnNumericData::kFloat) {
						float value;
						plug.getValue(value);
						
					}
					if(mfnaTest.type() == MFnNumericData::kDouble){
						double value;
						plug.getValue(value);
						
					}
					if(mfnaTest.type() == MFnNumericData::k3Double){
						double3 value;
						// get the plugs to the child attributes
						MPlug value1 = plug.child(0);
						MPlug value2 = plug.child(1);
						MPlug value3 = plug.child(2);

						// get the values from the child plugs
						value1.getValue(value[0]);
						value2.getValue(value[1]);
						value3.getValue(value[2]);
						
					}
					if(mfnaTest.type() == MFnNumericData::k3Float){
						float3 value;
						// get the plugs to the child attributes
						MPlug value1 = plug.child(0);
						MPlug value2 = plug.child(1);
						MPlug value3 = plug.child(2);

						// get the values from the child plugs
						value1.getValue(value[0]);
						value2.getValue(value[1]);
						value3.getValue(value[2]);
						
					}
					if(mfnaTest.type() == MFnNumericData::kInt){
						int value;
						plug.getValue(value);
						
					}
				}
