# Step (RealityKit) Outputs a 1 or a 0 depending on whether the input is greater than or less than the edge value. ## Overview 0 if X < Edge, otherwise it returns 1.0 ## Parameter Types **Step (float):** |Input |Type | |------|-----| |`In` |Float| |`Edge`|Float| |Output|Type | |------|-----| |`Out` |Float| **Step (vector3h):** |Input |Type | |------|--------| |`In` |Vector3h| |`Edge`|Vector3h| |Output|Type | |------|--------| |`Out` |Vector3h| **Step (half):** |Input |Type| |------|----| |`In` |Half| |`Edge`|Half| |Output|Type| |------|----| |`Out` |Half| **Step (vector4h):** |Input |Type | |------|--------| |`In` |Vector4h| |`Edge`|Vector4h| |Output|Type | |------|--------| |`Out` |Vector4h| **Step (vector2f):** |Input |Type | |------|--------| |`In` |Vector2f| |`Edge`|Vector2f| |Output|Type | |------|--------| |`Out` |Vector2f| **Step (color4f):** |Input |Type | |------|-------------| |`In` |Color4| |`Edge`|Color4| |Output|Type | |------|-------------| |`Out` |Color4| **Step (vector3f):** |Input |Type | |------|--------| |`In` |Vector3f| |`Edge`|Vector3f| |Output|Type | |------|--------| |`Out` |Vector3f| **Step (color3f):** |Input |Type | |------|-------------| |`In` |Color3| |`Edge`|Color3| |Output|Type | |------|-------------| |`Out` |Color3| **Step (vector4f):** |Input |Type | |------|--------| |`In` |Vector4f| |`Edge`|Vector4f| |Output|Type | |------|--------| |`Out` |Vector4f| **Step (vector2h):** |Input |Type | |------|--------| |`In` |Vector2h| |`Edge`|Vector2h| |Output|Type | |------|--------| |`Out` |Vector2h| ## Parameter descriptions - `In`: The input value. - `Edge`: The deciding value to which to compare the input. ## Discussion The Step node takes the `In` value and compares it to the `Edge` parameter. If the value is less than `Edge`, the node returns `0`. Otherwise, it returns `1`. --- Copyright © 2026 Apple Inc.
