Thread: jframe hashmap image (rectangle) animation problems post two

i posted the question at java-forums.org ( https://www.java-forums.org/new-java...-problems.html ) but realized no one uses the site much anymore so i am here trying to spread the word. please take a look if you can. i was talking about this in the cafe but i am woried i need more visibility

i fixed it by removing line #52 of the original thread.
