Prevent Python script tool from automatically filling output boxes

[AustinMilt]

I am creating a script tool as part of a Python Toolbox (.pyt) that performs some fairly basic tasks. The tool takes a single input file and creates three output rasters (see image). The problem I am having is that somewhere in Hidden ArcMap World, ArcMap is automatically populating the three output raster paths with the same path when the user gives the single input.

I have attempted to work around this in 2(+) ways.

• by having a check in updateMessages that raises an error if any of the ouputs match path/name


• by trying to automatically generate file names in updateParameters whenever the user has altered the input parameter (and the others dont yet have a "value" or have not been "altered")

How can I either [1] prevent ArcMap from populating parameter names without changing their status to "Optional" or [2] force ArcMap (or arcpy) to use different names when automatically populating those parameters?

Please post the top portion of your code where you parse out the input parameters.

Please post the top portion of your code where you parse out the input parameters.

Sorry, which part are you talking about? The execute() method?

# ~~ execute() ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #
    def execute(self, P, messages):
        """
        EXECUTE() calls ImpactScoreRasters.ImpactScoreRasters in Bungee's
        executing directory.
        """
        pK = self.paramOrder
        import arcpy
        
        # process parameters
        analysis = arcpy.Describe(P[pK['analysis']].value).catalogPath
        outPad = arcpy.Describe(P[pK['outPad']].value).catalogPath
        outRoad = arcpy.Describe(P[pK['outRoad']].value).catalogPath
        outPipe = arcpy.Describe(P[pK['outPipe']].value).catalogPath
        usePadFootprint = P[pK['usePadFootprint']].value

Or are you referring to the getParameterInfo portion?

    # ~~ __getParameterInfo__() ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #

        """Define parameter definitions"""
        
        import arcpy

        analysis = arcpy.Parameter(

            datatype = 'File',
            parameterType = 'Required',
            direction = 'Input'
        )

        usePadFootprint.value = False
