Light.intensity

Description

The Intensity of a light is multiplied with the Light color.

The value can be between 0 and 8. This allows you to create over bright lights.

// Pulse light's intensity over time.
var duration : float= 1.0;

var lt: Light;


function Start() {
    lt = GetComponent.<Light>();
}


function Update() {
    // Argument for cosine.
    var phi: float = Time.time / duration * 2 * Mathf.PI;

    // Get cosine and transform from -1..1 to 0..1 range.
    var amplitude: float = Mathf.Cos(phi) * 0.5 + 0.5;

    // Set light color.
    lt.intensity = amplitude;
}

    public float duration = 1.0F;
    public Light lt;

        float phi = Time.time / duration * 2 * Mathf.PI;
        float amplitude = Mathf.Cos(phi) * 0.5F + 0.5F;
        lt.intensity = amplitude;
