We have so far made a decision in our code only by using if, nested-if or series of if-else statements. In the previous section, we were able to get the particle effects into play using a series of if-else statements. However, it made our code look dirty and is cumbersome. An alternative and preferred way is using a Switch Statement. 

Switch Statement

• A switch statement is a streamlined decision making statement

• It is used when we want to make a decision based on the value of one variable and series of different constant that the variable stores (in our case: playerLife)

We already have declared the variable playerLife to be 3. The highest value of playerLife is 3 and the lowest is 0.

I created a new method called FireParticleEffect() to store our switch statement. Inside FireParticleEffect(), a switch statement was written. Common syntax of switch statement is:

• switch()

{

//cases are defined within this scope

case <constant>:

statement;

break;

default: 

}

Call Method

Finally FireParticleEffect() method was called in our existing OnCollisionEnter() method
