Below is the syntax ... if this rectangle intersect the argument rectagnle at one or more points, including on the boundary */ public boolean ... Two objects don't intersect if you can find a line that separates the two objects. e.g. the objects / all points of an object are on different sides of the line. The fun thing is, that it's sufficient to just check all edges of the two rectangles. If the rectangles don't overlap one of the edges will be the separating axis. A rectangle is represented as a list [x1, y1, x2, y2], where (x1, y1) are the coordinates of its bottom-left corner, and (x2, y2) are the coordinates of its top-right corner. Two rectangles overlap if the area of their intersection is positive. To be clear, two rectangles that only touch at the corner or edges do not overlap. Computing the area of a single rectangle is extremely simple: width multiplied by height. Computing the area of two rectangles is a little more challenging. They can either be separate and thus have their areas calculated individually, like this. Enabled: Computes the intersection of this Rectangle with the specified Rectangle. Returns a new Rectangle that represents the intersection of the two rectangles. If the two rectangles do not intersect, the result will be an empty rectangle. I am working on making it so I can move a Rectangle using my arrow keys but what I have currently isn't working. I initially had it so the Rectangle moved on it's own when I started the program. It moves based on the values of xVelocity and yVelocity. When I change those to 0 the object is stationary (as expected).
