A Blinking Turret?
I set up a turret that shoots at the player and has a temperature meter that can change color when the player gets to close. How could I go about getting the temperature to change from green to a blinking red and yellow, when the player gets too close?
using System.Collections;
public class TurretTemperture : MonoBehaviour
{
public Transform Target;
private float distance;
private Quaternion rotation;
private float lookAtDistance = 10;
private float reactionTime = 2;
void Update ()
{
if(Target)
{
distance = Vector3.Distance(Target.position, transform.position);
if (distance < lookAtDistance)
{
lookAt();
}
if (distance > lookAtDistance)
{
renderer.material.color = Color.green;
}
}
else
{
Target = null;
}
}
void lookAt ()
{
renderer.material.color = Color.red;
rotation = Quaternion.LookRotation(Target.position - transform.position);
transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * reactionTime);
}
}
You're already checking your distance, so use it. See if target is close enough to blink. If it is, make it blink. When it's not, make it stop blinking and go back to normal color. Answer to your question is basically your question itself.
I don't actually know how to make it blink. I can lerp the color from green to red, but that's about all i've figure out so far.
Ok here's something that works pretty well. Used an Coroutine to have the light on the turret platform blinking red and yellow when you get near it, and go back to green when you get far enough away. Doesn't work 100 percent, but it's not bad.
IEnumerator Blinking()
{
if(blink == true)
{
yield return new WaitForSeconds(.1f);
renderer.material.color = Color.red;
yield return new WaitForSeconds(.1f);
renderer.material.color = Color.yellow;
}
blink = false;
}
using System.Collections;
public class TurretTemperture : MonoBehaviour
{
public Transform Target;
private float distance;
private Quaternion rotation;
private float lookAtDistance = 10;
private float reactionTime = 2;
private float timer;
private bool blink;
void Start()
{
timer = Time.time;
}
void Update ()
{
if(Target)
{
distance = Vector3.Distance(Target.position, transform.position); //a line /vector
if (distance < lookAtDistance) // look at us
{
lookAt();
StartCoroutine("Blinking");
blink = true;
}
if (distance > lookAtDistance)
{
renderer.material.color = Color.green;
}
}
else
{
Target = null;
}
}
void lookAt ()
{
//renderer.material.color = Color.red;
rotation = Quaternion.LookRotation(Target.position - transform.position);
transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * reactionTime);
}
IEnumerator Blinking()
{
if(blink == true)
{
yield return new WaitForSeconds(.1f);
renderer.material.color = Color.red;
yield return new WaitForSeconds(.1f);
renderer.material.color = Color.yellow;
}
blink = false;
}
}
