Use an editing logic function with booleans?

Lee_Hesketh

Can an editing logic function be used to tick a boolean check box in the UI? If so, how?
Thanks

Hi Lee, this simple example creates radio buttons.

FeatureScript 505;
import(path : "onshape/std/geometry.fs", version : "505.0");

annotation { "Feature Type Name" : "My Feature", "Editing Logic Function" : "RadioButtons" }
export const myFeature = defineFeature(function(context is Context, id is Id, definition is map)
    precondition
    {
        annotation { "Name" : "My Boolean", "Default" : true }
        definition.myBoolean1 is boolean;

        annotation { "Name" : "My Boolean" }
        definition.myBoolean2 is boolean;
    }
    {
        // Define the function's action
    });

export function RadioButtons(context is Context, id is Id, oldDefinition is map, definition is map, isCreating is boolean) returns map
{
    if (oldDefinition.myBoolean1 != definition.myBoolean1) // this means if the value has been changed by the user
    {
        definition.myBoolean2 = !definition.myBoolean1;
    }
    if (oldDefinition.myBoolean2 != definition.myBoolean2)
    {
        definition.myBoolean1 = !definition.myBoolean2;
    }
    return definition;
}

Ah, okay. So what I want to achieve is I have a boolean that is defaulted to false. Then later on in the code, it is set to true if certain conditions are met. How would I set it to true in the UI?

You can't set it from the body of your regeneration code, only from the editing logic function which is only triggered if the user changes something. So if the user input triggers some logic to set a checkbox, that logic must be in your editing logic function.

If you omit isCreating the logic will only work on feature creation and not editing. You are getting an error probably because you already have the feature created in the Part Studio. Delete the feature and create a new one.
