How to make perfect particle effects when player jump on enemy's head?

Hello C3 experts,

I'm learning C3 platformer game, what i'm trying to create actually. Player jumping over the enemy head then particles effects then enemy dead by its destroy.

But its gone wrong, the particles effects showing every time when the player jump. this is the problem i'm facing, so it would be great if some one help me to get fixed this.

Set the type to one-shot to make the particle play once.

Thanks for your reply, actually It is already in one shot only, the problem is the particle is playing every time the player jump.
