Trying to make a animation where it gradually grows and then shrinks but it bugs

Hi! There seems to be some errors that 1) you are missing some semicolons and 2) some lines need (int) keyword to convert float to int. Also there is a size parameter that is not defined anywhere.

“it bugs” can mean that you have the error that prevents the code from running or that the code runs but not as you intended. It would be much better if you can elaborate a bit more on the problem itself :slight_smile:

Ok, the program makes it so the the ellipses just grow really fast and then shrinks a bit and just repeats itself

I will try what you said
