Hi,everyone,above are my coding part.Im kinda new with processing.I suppose it is because I loaded images in draw(),so it would load an image 60 times every second.But i don't know how to tackle that . I would be really appreciate it if any of you guys help me out of it.Thanks!;)

sorry Im new here apologize about bad reading experience

You can fix the reading experience by editing your post and properly formatting your code using the code button. Better yet, please post a MCVE that demonstrates the problem instead of your whole project.

Edit post, highlight code, press ctrl-o to format

The obvious thing is all the image resizing that you are doing. Either resize the images using a graphics program or do it immediately after the load in setup, don't do it in draw because it's expensive and slow.

But we don't have your images so I'm guessing.
