I have a class that has been entitled as Ball. Within said class I have an instance of java.awt.Rectangle. 

 package com.ncagle.angles;

 import java.awt.Color;
 import java.awt.Graphics;
 import java.awt.Rectangle;

public class Ball {

public Rectangle rect;

public Ball() {
    rect = new Rectangle(10, 10, 16, 16);
}

public void tick() {

}

public void draw(Graphics g) {
    g.setColor(Color.WHITE);
    g.fillRect(rect.x, rect.y, rect.width, rect.height);
}

}

What I'm wishing to accomplish is to have said Rectangle move at a specific angle (ex: 35°). I haven't tried anything because I have no idea how I would go at this. I'm in 8th Grade. I just learned what Pythagorean Theorem is about two weeks ago. If anybody could show me how this would be done, that would be great. Thank you.

  • You have some basic problems you need to solve, first, based on a start point, you need to be able to calculate the end point which, if you drew a line between them, would be the desired angle. This represents a "find the point on a circle based on a given angle" problem. Next, you need to calculate the point along the line you're at, at any given time – MadProgrammer Apr 14 '16 at 23:20

  • Before you ask, I don't understand the maths either, I just know how to use it – MadProgrammer Apr 14 '16 at 23:25
