Description
The SpringDamp
method is a static function of the Vector3
struct that performs a spring-damping operation on a vector. This method is useful for simulating spring-like behavior in animations or physics simulations, where a vector smoothly approaches a target vector over time, with a spring-like oscillation and damping effect.
Usage
To use the SpringDamp
method, you need to provide the following parameters:
current
: A reference to the current Vector3
position.
target
: A reference to the target Vector3
position that the current vector should approach.
velocity
: A reference to the current velocity of the vector, which will be updated by the method.
smoothTime
: A float
representing the time it takes to reach the target under ideal conditions.
deltaTime
: A float
representing the time elapsed since the last call to this method.
frequency
: A float
representing the frequency of the spring oscillation.
damping
: A float
representing the damping ratio, which affects how quickly the oscillations die out.
The method returns a Vector3
that represents the new position after applying the spring-damping effect.
Example
Vector3 current = new Vector3(0, 0, 0);
Vector3 target = new Vector3(10, 10, 10);
Vector3 velocity = Vector3.Zero;
float smoothTime = 0.3f;
float deltaTime = 0.016f; // Assuming 60 FPS
float frequency = 1.0f;
float damping = 0.5f;
Vector3 newPosition = Vector3.SpringDamp(ref current, ref target, ref velocity, smoothTime, deltaTime, frequency, damping);
// newPosition now contains the updated position after applying spring-damping.
