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 animations where abrupt changes are undesirable. It calculates a damped spring-like motion, which is often used in game development for camera movements, object following, or any scenario where a smooth transition is needed.
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 of the vector. This is a reference parameter.target: The target position to which the vector should move. This is a reference parameter.velocity: The current velocity of the vector. This is a reference parameter and will be updated by the method.smoothTime: The time it takes to reach the target. A smaller value will result in a faster transition.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 velocity = Vector3.Zero; float smoothTime = 0.3f; float deltaTime = 0.016f; // Assuming 60 FPS Vector3 newPosition = Vector3.SmoothDamp(ref currentPosition, ref targetPosition, ref velocity, smoothTime, deltaTime); // newPosition now holds the updated position after applying smooth damp.
