Code, is going up at the beginning, if change to the right direction, turn 90 degrees clockwise, the 90 degrees counterclockwise to the left, but I like to write only clockwise or counterclockwise, a great god please help solve what the problem is this

You use rotateBy give it a try

CodePudding user response:

Upstairs is the solution, you look at RotateTo realization you will understand

CodePudding user response:

Have a built-in function very convenient
