arcpy.GetParameterAsText not passing arguments to the script

HaydenWilson3

I have been working on an arcgis tool which takes the co-ordinate system from an input raster and reprojects a vector to the same co-ordinate system.

The script works fine when i hard code the addresses for the workspace and input datasets. But as soon as I try to pass those as parameters in a toolbox it no longer works.

Can anyone here point out what I am doing wrong?

It appears that you are using a Python toolbox script (.pyt file) and including GetParametersAsText which works with custom Python script tool.  Comparing custom and Python toolboxes might help clarify some of the differences.

Here is your script with the formatting that Dan Patterson‌ is suggesting:

Since the parameters are defined inside the Python toolbox script (lines 21-45) versus a "wizard" with the custom script, you don't need the GetParameters as text in lines 51-54.  Try replacing lines 47 to the end with:

    def execute(self, parameters, messages):
        """The source code of the tool."""

        # Define some paths/variables
        outWorkspace = parameters[0].valueAsText
        arcpy.env.workspace = outWorkspace
        input_raster = parameters[1].valueAsText
        input_features = parameters[2].valueAsText

        output_features = outWorkspace + "\\projected.shp"

        out_coordinate_system = arcpy.Describe(input_raster).spatialReference
        proj_grid = arcpy.Project_management(input_features, output_features, out_coordinate_system)

        return
