Types and Conversors

The NodeGraph features a conversion system that allows you to convert objects from one type to another.

How It Works​

When starting the application, NodeGraph scans for all existing converters in the project. For each converter found, it creates an instance of the corresponding class, which will be used whenever a conversion between the defined types is needed.

Examples​

Here are two examples of converters already implemented in the project:

Convert a Component to Transform:

[Description("component.transform")]
Transform ITypeConverter<Transform, Component>.Convert(Component source)
{
    return source.transform;
}

Convert a Component to GameObject:

[Description("component.gameObject")]
GameObject ITypeConverter<GameObject, Component>.Convert(Component source)
{
    return source.gameObject;
}

Check the CustomConverters class to see all the existing implementations. This will provide a solid foundation for understanding how new converters can be created and applied in your project.

Creating Custom Converters​

The existing converters handle most common scenarios, but you can create custom converters to meet specific needs. To add a new converter:

  1. Create a New Class: Implement the ITypeConverter<TOut, TIn> interface in your new class.
  2. Define the Convert Method: Implement the Convert method to specify how the conversion should be performed.

To add a description for your converter, use the System.ComponentModel.DescriptionAttribute in your Method. This Attribute will display a tooltip with a description when you hover over the TypeConverter label in the Inspector.
