The Vector3.SmoothDamp method is used to smoothly transition a vector from a current position to a target position over time. This method is particularly useful for creating smooth movements or transitions in animations or physics simulations. It calculates a damped spring-like motion between the current and target vectors, adjusting the velocity to ensure a smooth approach.
To use the Vector3.SmoothDamp method, you need to provide the current position, target position, current velocity, smooth time, and delta time. The method will return the new position after applying the smooth damp effect.
Parameters:
current: The current position vector. This is passed by reference and will be updated with the new position.target: The target position vector. This is the position you want to move towards.velocity: The current velocity vector. This is passed by reference and will be updated with the new velocity.smoothTime: A float representing the time it takes to reach the target. Smaller values result in faster transitions.deltaTime: The time elapsed since the last frame. This is typically the frame time in seconds.Vector3 currentPosition = new Vector3(0, 0, 0); Vector3 targetPosition = new Vector3(10, 10, 10); Vector3 currentVelocity = Vector3.Zero; float smoothTime = 0.3f; float deltaTime = 0.016f; // Assuming 60 FPS Vector3 newPosition = Vector3.SmoothDamp(ref currentPosition, ref targetPosition, ref currentVelocity, smoothTime, deltaTime); // currentPosition and currentVelocity are updated with the new values.
