Mastering the Zigzag Flight Pattern

Programming a Zigzag Flight Pattern with If Statements

• This is the seventh video in the "Get Control" video series for using the Telo drone with Drone Blocks.
• In the previous video, the drop rate and drop down timer code were programmed using maths.
• This video covers the programming concept of selection, specifically the if statement.
• The goal is to program the Telo drone to fly in a zigzag pattern, which involves abrupt alternate left and right turns.
• The code includes five variables: counter, forward distance, zig, zag, and total zigzags.
• These variables are dragged onto the stage and duplicated using the "duplicate" function.
• The loop, or iteration, is used to repeat the zigzag flight pattern a certain number of times.
• The code for a zigzag without an if statement is demonstrated and flown in the drone simulator.
• The if statement is introduced to determine if the drone should turn left (zig) or right (zag).
• The if statement includes an else statement to cover both possibilities.
• The total number of zigzags is divided by two to account for the fact that each iteration of the loop determines whether to zig or zag.
• The code is adjusted to offset the initial turn to the right by 45 degrees to ensure a clean zigzag flight pattern.
