Configurations in Feature Script

Kira_Lee · November 2021

I have been trying to add a specific configuration from a part studio in my feature script. I thought I had done it correctly - I even tried following this forum exactly (renaming my ID's in the part studio and feature script to "Orientation" and "Top", "Left", "Right"), but this still doesn't work.

        var query;
        var transform = identityTransform();
        if (size(evaluateQuery(context, definition.mateConnector)) == 1)
        {
            transform = toWorld(evMateConnector(context, { "mateConnector" : definition.mateConnector }));
        }
        var instantiator = newInstantiator(id + "instantiator");

            query = addInstance(instantiator, API_BOX::build, {
                        "configuration" : {
                            "Orientation" : Orientation_conf.Top
                        },
                        "transform" : transform
                    });<br>

I want to mention that the code works correctly if I take out the "Configuration" part - it just doesn't put the configuration I want since it uses the default then.

The error I'm getting is "variable Orientation_conf not found". Is there a key factor I'm missing? I'm very stuck, so thank you for any help in advance!

I can't see your document, but you may have been on the right track before -- you may have to useAPI_BOX::Orientation_conf.Top

The name of the configuration table is "Orientation", and it looks like it has row names "Top", "Left", and "Right". Hence, the configuration is expecting something like:

"configuration" : { "Orientation" : "Top" }

Note that in the previous example, Top is a string, as denoted by the quotation marks "". If you want to set the configuration dynamically, you can use a variable:

const myOrientation = "Top";
"configuration" : { "Orientation" : myOrientation }

If you try putting Top without the quotation marks, FeatureScript assumes you're trying to pass in the value of a variable named Top:

"configuration" : { "Orientation" : Top } // ERROR: No variable named Top!

const Top = "Right";
"configuration" : { "Orientation" : Top } // generates the "Right" configuration

Lastly, the toString() method can be used to convert certain values into strings - for example, if you have an enum with values Top, Right, and Left, you can use the enum directly by calling toString on it:

"configuration" : { "Orientation" : toString(definition.myEnum) } // where myEnum is an enum parameter corresponding to an enum with values Top, Right, and Left

Hopefully that makes some sense. You can also take a look at my vex component feature, which is a wrapper of my point derive feature and allows my VEXU team to quickly bring in motor mounts and configured c-channels:

I tried this and now I am getting a different error:

Parameter Orientation must be a valid Orientation_conf

This is the exact code:

var orientation = "Top";
var query = addInstance(instantiator, API_BOX::build, {
                "configuration" : { "Orientation" : orientation },
                "transform" : transform
            });
