RaycastDistance

Purpose

Measure distance to first raycast hit.

Key inputs / outputs

• Inputs: physicsMode, center, direction, distance, layerMask.
• Outputs: float distance (float.MaxValue if no hit).

Success / Failure semantics

• Returns finite distance when hit exists, float.MaxValue otherwise.

Important limitations

• Supports both Physics2D and Physics3D.
• Invalid position values can fail node validation.
