QUESTION
I am trying to animate a circle on Canvas using the keyboard cursor keys. The problem is the clearRect() function is not being used properly and there is this bizzare line that draw with the circle when you use the cursor keys.
I have tried reordering the code including the cleaRect() function but that does not help.
...ANSWER
Answered 2019-Mar-30 at 06:55Your use of clearRect() is fine. The problem is your code has just one open path which gets extended each time a key is pressed, so when you call ctx.fill() and ctx.stroke() it follows this longer and longer path.
Add beginPath() and closePath() to each of your cases and you will no longer get the extraneous lines and such.
