Conditions conditions
We use conditions all the time!
But what are conditions?
They are things that decide!
Conditions in coding, well you use them when
You need to make a decision
Usually they have an IF and a THEN
And you can use them again and again!
You use conditions in your life every day
When you think about choices when you work and you play
You use IFs and THENs in your lives every day
Listen up and I will throw some examples your way
IF you are hungry THEN you should eat
IF you are smelly THEN you should wash your feet
IF you finish your homework THEN you can watch TV
And IF you want to learn THEN listen to me!
Conditions conditions
We use conditions all the time!
But what are conditions?
They are things that decide!
Imagine you are coding a simple game
To shoot a ball into a hoop is the aim
Two points for each ball that goes in
But now this brings up a good question
How is the computer gonna know when
To add two points when the ball goes in?
I think it's time to use a condition
And of course it's gonna have an IF and a THEN
Let's go!
So points are stored in a variable called theScore
TheScore starts at zero but there's gonna be more
Next, hmmm what are we gonna do?
Set up a true-false variable is what we'll do
We'll call this new variable isItIn
It's set to false when you start the game
But it will change to true if the ball goes in
Now we'll set up a condition
That will check the value of IsItIn
And if it is true, you know what we're gonna do?
Then the Score will go up by two!
Aww ya
You're doing it
Just remember, a condition uses an IF and THEN
To plan the path of a decision!
Ya a condition uses an IF and THEN to plan the path of a decision!
Ya a condition uses an IF and THEN to plan the path of a decision!
Ya a condition uses an IF and THEN to plan the path of a decision!
