Particle emitter almost doing what I want with C# but not quiet there yet. Help needed.

Hi,

Im trying to make a little game where you can fly a spaceship with keys (W,S,A,D) so far the ship is flying nicely and I have a particle emitter that reacts when I press and hold these keys. But the particles don't disappear when I release the key it sort of freezes and remains still. Heres the code I have so far only using the key "W":

Code (CSharp):

1. public class ParticleEmitter1: MonoBehaviour
2. {
3.     public ParticleEmitter smallflames2;
4.  
5.  
6.  
7.  
8.  
9.  
10.  
11.  
12.  
13.             void Update () {
14.  
15.     if(Input.GetKey(KeyCode.W)){
16.             smallflames2.particleEmitter.enabled = true;
17.     }else if(Input.GetKeyUp(KeyCode.W)){
18.             smallflames2.particleEmitter.enabled = false;;
19.        
20.        
21.     }
22. }
23. }

I would really appreciate any help I can get on this issue, it's so close to working perfectly. Any ideas?

 

I posted several times without getting any answers from the community, Daddy's not mad, he's disappointed!


I've been stuck with this silly little issue for 14 days now and its driving me insane!



I have a prefab of a particle emitter that looks like thrusters of an engine, and its activated with the key "w".

My issue is that the particle emitter starts and stops as it should but the particles don't disappear when I release the key. heres the code I have so far:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class ParticleEmitter1: MonoBehaviour
5. {
6.     public ParticleEmitter smallflames2;
7.  
8.  
9.  
10.  
11.  
12.  
13.  
14.  
15.  
16.             void Update () {
17.  
18.     if(Input.GetKey(KeyCode.W)){
19.             smallflames2.particleEmitter.enabled = true;
20.  
21.     }else if(Input.GetKeyUp(KeyCode.W)){
22.             smallflames2.particleEmitter.enabled = false;
23.  
24.  
25.  
26.        
27.        
28.     }
29. }
30. }

Something's missing at the end that tells the "smallflames2" to be invisible upon release of the key. PLEASE HELP!!!!!!!!! before I loose my mind.

 

Replace else if with else. Remove all contents from brackets.

 

Use GetKeyDown instead of GetKey

 

Have you checked the documentation for ParticleEmitter? I havent worked with them but this here seems to do what you want: http://docs.unity3d.com/ScriptReference/ParticleEmitter.ClearParticles.html

 

Why not just make your particles world space so they won't follow you and will realistically disperse? You can have them change color, grow, shrink, become transparent, slow down, speed up, etc.

 

Daddy needs verbose topic titles.

 

Daddy also needs a xanax

 

Never knew it was possible! :O

This is like a new way to combat duplicate threads.

 

I didn't know about that either. I'm impressed and afraid.

 

You guys are great! thanks, Now Daddy's calm and xanaxed ;-) I will try everything suggested and truly appreciate your help. Will update if/when it works

 

Here we go. I had a friend of mine teach me some things that REALLY helped in regards to this particle issue.
Basically I had the right idea but I just had to enable/disable the particle Renderer component in accordance with holding down the key. Here's the code, hope it helps others in the same situation:

Code (CSharp):

1. public class ParticleEmitter1: MonoBehaviour
2. {
3.     public ParticleEmitter smallflames2;
4.  
5.     private ParticleRenderer thisParticleRenderer;
6.  
7.  
8.     void Start () {
9.         thisParticleRenderer = gameObject.GetComponent<ParticleRenderer> ();
10.         smallflames2.particleEmitter.enabled = true;
11.     }
12.  
13.  
14.  
15.  
16.  
17.     void Update () {
18.         if(Input.GetKey(KeyCode.W) || Input.GetKey(KeyCode.D))
19.         {
20.  
21.             thisParticleRenderer.enabled = true;
22.        
23.  
24.         }
25.         else
26.         {
27.             thisParticleRenderer.enabled = false;
28.         }
29.  
30.     }
31.    
32. }
33.
