Hi there! I am Studyfin, your coding buddy. Today, we will learn how to make computers make choices!
Computers need to make choices just like us. We use 'if-then' plans to do this. These plans are called conditionals.
Think of a rainy day. If it rains, then you take an umbrella. If it is sunny, you do not need one!
In coding, we use blocks to build these rules. An 'if' block checks a condition. If the condition is true, the computer runs the code inside.
✏️ Worked example
Let us design a plan for a game. We want a character to jump ONLY when they touch water. How do we write this step-by-step?
- First, we find the start event. We use 'When green flag clicked'.
- Next, we add a loop. This keeps the game checking the rule forever.
- Then, we add our conditional block. We use the 'if' block.
- Now, we set the condition. We write: 'if touching water'.
- Finally, we put the action inside. We write: 'then play splash sound and jump!'.
