Hello! I want to make a particle effect. The game I am making is a Flappy Bird like and I am trying to add that effect to my player which is the bird in the current situation.

What I want to happen is whenever I am press Space button to jump I want to also see that particle effect play.

How do I do that?

Thanks!

Step 1

Find the documentation page for Particle System and look for Public Methods list there.

→ Unity - Scripting API: ParticleSystem

Any “Play” method or something like that? You bet!

→ Unity - Scripting API: ParticleSystem.Play

Stop:

→ Unity - Scripting API: ParticleSystem.Stop

Also Emit:

→ Unity - Scripting API: ParticleSystem.Emit

So it’s

[SerializeField] ParticleSystem _particleSystem;

void Start ()
{
    _particleSystem.Play();
}

Step2: Play on key press

What you need is Input.GetKeyDown( KeyCode.____ )

→ Unity - Scripting API: Input.GetKeyDown

Step3: Combine steps 1 & 2

[SerializeField] ParticleSystem _particleSystem;

void Update()
{
    if( Input.GetKeyDown(KeyCode.Space) )
    {
        _particleSystem.Stop();
        _particleSystem.Play();
    }
}
