Code Duplication Refactoring on Conditional Conditions

Mj Tapiru — Mon, 09 Sep 2019 03:36:20 +0000

Sometimes you come accross duplicated code blocks that the only difference is having an additional condition to check if another condition is true. An Example of the Idea is given below.

From

if ( condition1 && condition2 ) {
//doSomething1

    if ( conditionA || conditionB ) {
        //doSomething2
    }

} else if ( condition1 ) {
//doSomething1

    if ( conditionA ) {
        //doSomething2
    }

}

In the above example, the only difference is if condition2 == true then check for conditionB
To refactor it, we leave all execution rights to condition2 and conditionB

Assume:

condition1 = true

conditionA = false

with that, we get:

if ( true && condition2 ) {
//doSomething1

    if ( false || conditionB ) {
        //doSomething2
    }

} else if ( true ) {
//doSomething1

    if ( false ) {
        //doSomething2
    }

}

In the above example in the first if block, you will only execute doSomething2, if and only if condition2 AND conditionB are true.
So we can refactor it to the code below.

To

if ( condition1 ) {
//doSomething1

    if ( conditionA || (condition2 && conditionB) ) {
        //doSomething2
    }

}

Gamedev, Where should I start?

Hi! I was hoping to get started on Game Development.

I'm currently a web developer and is decent in javascript. I've tried Unity before and made an incomplete but working Endless Runner Game.

Since I have confidence in my javascript coding skills, I'm hoping to learn gamedev on web and I have my sight on PhaserJs. Do you have any tips or links on resources I could use? Or any suggestions for another framework in gamedev on web? If you have any-, anything at all.

I WOULD LOVEEEEE IT if you could share. ^^

Also if you would be so kind as to mentor me on the steps, I would gladly appreciate it.

Hoping to see great comments and suggestions. Thanks!
