Change color of Particles
Hi,
What I have is an Ellipsoid Particle Emitter, Particle Animator, Particle Renderer, and a World Particle Collider (in that order) attached to a prefab that I have named "ParticlePrefab". The ParticlePrefab is attached to my Player GameObject.
Everytime I press 'h' on the keyboard, I see particles emit, which is what I want. Now I need to be able to change the color of the particles, through a script. Here is what I have so far:
using UnityEngine; using System.Collections;
public class Player : MonoBehaviour {
// Allow our PlayerClass awareness of the Particle public GameObject ParticlePrefab; private GameObject instantiated;
private Vector3 lastPosition;
// Values are set in Unity3D Interface public float MoveSpeed; public float RotateSpeed;
// Update is called once per frame void Update () {
Move_Player();
}
void OnTriggerStay(Collider other) {
if (Input.GetKeyDown("h") && instantiated == null)
{
instantiated = (GameObject) Instantiate(ParticlePrefab, transform.position, Quaternion.identity);
//Particle [] p = p.ColorAnimator = Color.red;
Particle [] PlayerParticles = particleEmitter.particles;
for (int i = 0; i < PlayerParticles.Length; i++)
{
PlayerParticles[i].color = Color.red;
}
particleEmitter.particles = PlayerParticles;
Color[] MyColor = particleAnimator.colorAnimation;
MyColor[4] = Color.red;
particleAnimator.colorAnimation = MyColor;
}
} void Move_Player() { float MoveForward = Input.GetAxis("Vertical") MoveSpeed Time.deltaTime; float MoveRotate = Input.GetAxis("Horizontal") RotateSpeed Time.deltaTime;
// Move the player
transform.Translate(Vector3.forward * MoveForward);
transform.Rotate(Vector3.up * MoveRotate);
if (Vector3.Distance(lastPosition, transform.position) > 0.01f)
{
lastPosition = transform.position;
if (instantiated != null)
{
instantiated.particleEmitter.emit = false;
Destroy(instantiated, 0.90f);
}
}
}
}
If this cannot be done through a script, could someone show me how to use AddComponent so that I can add a particle emitter, of which i will color, the player component and get it to work in the same way?
Alright so I made a new particle emitter for red particles and just added to a prefab, deleted the system, and added the prefab to my player Game Object and it worked. But I would prefer to change it through code how can I do that?
Here, this will change your colors programatically. I didn't touch much of it so a large part is hard coded like you had it.
using UnityEngine; using System.Collections; using System.Collections.Generic;
public class NewBehaviourScript : MonoBehaviour {
// Allow our PlayerClass awareness of the Particle public ParticleEmitter Particles;
// Values are set in Unity3D Interface public float MoveSpeed; public float RotateSpeed;
private ParticleEmitter spawnedParticles; private ParticleAnimator particleAnimator;
private Vector3 lastPosition;
// Update is called once per frame void Update () {
Move_Player();
}
void OnTriggerStay(Collider other) {
if (Input.GetKeyDown("h") && spawnedParticles == null)
{
spawnedParticles = Instantiate(Particles, transform.position, Quaternion.identity) as ParticleEmitter;
particleAnimator = spawnedParticles.GetComponent<ParticleAnimator>();
Color[] m_Color = particleAnimator.colorAnimation;
m_Color[4] = Color.red;
particleAnimator.colorAnimation = m_Color;
}
} void Move_Player() { float MoveForward = Input.GetAxis("Vertical") MoveSpeed Time.deltaTime; float MoveRotate = Input.GetAxis("Horizontal") RotateSpeed Time.deltaTime;
// Move the player
transform.Translate(Vector3.forward * MoveForward);
transform.Rotate(Vector3.up * MoveRotate);
if (Vector3.Distance(lastPosition, transform.position) > 0.01f)
{
lastPosition = transform.position;
if (spawnedParticles != null)
{
spawnedParticles.emit = false;
Destroy(spawnedParticles.gameObject, 0.90f);
}
}
} }
But unless there is something wrong with the way you have it, using a prefab is likely faster and easier. The old adage "Why fix something that's not broken." seems fitting here.
Any example of simular code for new (shuriken) particle system?
I'm having the same problem...... I have particle emitters that i want to change the colour of procedurally (as in to flow through from say green to red over time when i prompt it to) how would I go about doing this?
