Description
The MathX.SmoothDamp
method is used to smoothly transition a value from a current state to a target state over time. This method is particularly useful for creating smooth animations or transitions in game development, where abrupt changes in values can be visually jarring. The method calculates a new value based on the current value, target value, and the velocity, adjusting the transition speed according to the specified smooth time and delta time.
Usage
To use the SmoothDamp
method, provide the current value, target value, a reference to the velocity, the desired smooth time, and the delta time (usually the time elapsed since the last frame). The method will return the new value that is closer to the target, and it will update the velocity reference to reflect the current rate of change.
Parameters:
current
: The current value to be smoothed.
target
: The target value to reach.
velocity
: A reference to the current velocity, which will be updated by the method.
smoothTime
: The time it should take to reach the target value. A smaller value will result in a faster transition.
deltaTime
: The time elapsed since the last frame, typically provided by the game loop.
Example
// Example usage of MathX.SmoothDamp
float currentValue = 0.0f;
float targetValue = 10.0f;
float velocity = 0.0f;
float smoothTime = 0.3f;
float deltaTime = 0.016f; // Assuming 60 FPS
float newValue = MathX.SmoothDamp(currentValue, targetValue, ref velocity, smoothTime, deltaTime);
// newValue will be closer to targetValue, and velocity will be updated accordingly.
