How to make an explosion effect by Particle System in Unity ~ “Karaage” Style

爆発エフェクトの完成イメージ

The complete image of an “Explosion” effect

In this article, I introduce how to make an explosion effect from a reference image of a deep-fried chicken (Karaage in Japanese) in Unity. This approach was popular a long time ago but I will dare to introduce it today! Firstly, go shopping for some deep-fried chicken for a reference image. It doesn’t matter where to buy it, at a hyper store or a convenience store. You can cook it by your self, of course. The shown below is what I bought this time.

Set Shape to “Sphere”.

Create a Material for the particles

Create a new Material for the effect. Set Material’s Shader to Particle > Additive.

パーティクルのマテリアルを作る

Create a Material for the particle

Assing a texture

Prepare a texture for the effect. I picked up a piece of deep-fried chicken from the image, and make a texture blurred around the boundary.

  Assign the image to “Particle Texture”.

テクスチャをからあげに

Assign “Deep-fried Chicken” to the texture!

  Play the particles to check.

The particle became “Deep-fried chicken” now.

 

The setting of the Emission module

Set the parameters of the Emission module. Set “Rate over Time” to zero. Add a Burst with Count set to 100.

Let’s set the parameters for the main module. Set the parameters as follows: Duration: 2.00 Start Lifetime: 1.5 and 2 with “Random between two constants” selected Start Size: 0.4 and 1.5 with “Random between two constants” selected Start Rotation: 0 and 360 with “Random between two constants” selected

The setting of the “Color over Lifetime” module

Let’s colour the explosion. Make a gradation that starts with orange-type colour. Set the parameter for Alpha so that it becomes transparent gradually.
