in java processing, as you see the picture my red object will be travelling between the screen using my WASD keys, and inbetween the four circles its going to trigger rectangles to appear, as they are previously hidden. This however must be done with arrays. Help would be appreciated thanks.

Most useful module is arrays and strings In this part we will have Fizzy reveal a pattern of rupees. The position of the rupees is set from the start but they are hidden until Fizzy walks/swims over them. You should store a number of arrays to represent the x position, y position and status (hidden or revealed) of each rupee. When the program starts, the rupees are all hidden in a heart pattern, an example will be posed in the class forums. As Fizzy walks over a hidden rupee, it becomes visible. That rupee will stay visible if Fizzy walks over it again at any point. Fizzy must walk over the rupees, not under them. This means that rupees should never obscure Fizzy. Rupees should be a square centered between the poles with 40 pixel long sides. Rupees should be green. It might be useful to show hidden rupees during development but make sure they are not visible unless they have been walked over in your submitted code
