Feed the Fish - Hour of Code 2022 | Codesters Curriculum

STEP 10: We'll use this interval event to make fish food fall from the top of the screen every few seconds.

Remember, an indent is 4 spaces or 1 tab. Commands must be indented in an event in order to run.

Find and delete this line in the interval event: ····sprite.turn_left(15)¬
In LOGIC, go to and drag out Random Integer. Drop it INDENTED inside of the interval event.

We are going to use this random number to control where the food appears.
