The SpringDamp method in the MathX class is used to simulate a spring-damping system. It calculates the next position of a value that is being damped towards a target value over time, using a spring-like motion. This method is useful for creating smooth transitions and animations that mimic the behavior of physical springs.
To use the SpringDamp method, provide the current value, target value, a reference to the velocity, the time step (deltaTime), the frequency of the spring, and the damping ratio. The method will return the new value after applying the spring-damping effect.
Parameters:
current (Single): The current value that is being damped.target (Single): The target value towards which the current value is moving.velocity (Single&): A reference to the current velocity of the value. This will be updated by the method.deltaTime (Single): The time step for the simulation, typically the time elapsed since the last frame.frequency (Single): The frequency of the spring, which affects how quickly the value oscillates.damping (Single): The damping ratio, which affects how quickly the oscillations die out.// Example usage of SpringDamp float currentValue = 0.0f; float targetValue = 10.0f; float velocity = 0.0f; float deltaTime = 0.016f; // Assuming 60 FPS float frequency = 1.0f; float damping = 0.5f; float newValue = MathX.SpringDamp(currentValue, targetValue, ref velocity, deltaTime, frequency, damping); // newValue now contains the updated position after applying spring damping.
