VisualShaderNodeStep
====================

**Inherits:** :ref:`VisualShaderNode<class_VisualShaderNode>` **<** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

Calculates a Step function within the visual shader graph.

Description
-----------

Translates to ``step(edge, x)`` in the shader language.

Returns ``0.0`` if ``x`` is smaller than ``edge`` and ``1.0`` otherwise.

enum **OpType**:

- **OP_TYPE_SCALAR** = **0** --- A floating-point scalar type.

- **OP_TYPE_VECTOR_2D** = **1** --- A 2D vector type.

- **OP_TYPE_VECTOR_2D_SCALAR** = **2** --- The ``x`` port uses a 2D vector type, while the ``edge`` port uses a floating-point scalar type.

- **OP_TYPE_VECTOR_3D** = **3** --- A 3D vector type.

- **OP_TYPE_VECTOR_3D_SCALAR** = **4** --- The ``x`` port uses a 3D vector type, while the ``edge`` port uses a floating-point scalar type.

- **OP_TYPE_MAX** = **5** --- Represents the size of the :ref:`OpType<enum_VisualShaderNodeStep_OpType>` enum.
