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.

By the way, I ate them up after taking the photos.

How to make an explosion effect

Add a Particle System

Select GameObject > Effects > Particle System

Particle Systemの追加

Add a Particle System

It creates particles in the Scene.

パーティクルが生成された

Particles are created.

Set Shape to “Sphere”

In the Shape module, set Shape to “Sphere” and set Radius to 0.2.

ShapeをSphereにする

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.

The image of deep-fried chicken processed for the effect.

 

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.

パーティクルがからあげになった

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.

Emissionの設定

The setting of the Emission module

The setting of the main module.

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

メインモジュールの設定

The setting of the main module

The setting of the “Size over Lifetime” module

Set the “curve for Size over Lifetime”.

Now, I adjust the “Start Size” once more.

Size over Lifetimeモジュールの設定

The setting of the “Size over Lifetime” module

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.

Adjust the whole image

Adjust the parameters again while checking how the explosion looks.

全体の調整

Adjust the whole image.

 

The explosion effect completed

It ended up with the shown below.

In this article, I introduced how to make an explosion effect from the image of deep-fried chicken as a reference.

Deep-fried chicken, or Japanese Kara-age, is tasty not only for dinner but also as a reference image!
