Conditional statements are an necessary a part of programming. They will let you management the circulate of your program primarily based on sure situations. In Code.org, conditional statements are used within the “If” block.
The “If” block permits you to specify a situation that, if true, will execute a set of instructions. If the situation is fake, the instructions will likely be skipped.
To make use of the “If” block, you will want to:
- Drag the “If” block into your workspace.
- Click on on the “Situation” area and choose a situation from the dropdown menu.
- Drag the instructions that you simply wish to execute if the situation is true into the “Do” area.
Right here is an instance of the best way to use the “If” block:
If (participant.x > 100) { participant.moveRight();}
This code will transfer the participant to the proper if the participant’s x-coordinate is bigger than 100.
