问题 I have written the following function for projectile motion of different force and angle, but it doesn't work properly. Where have I gone wrong? I want something like the Angry Birds game. Code: public void shootBall(int timeCounter){ int gravity = 4; double time = timeCounter/40.0; int velocity = force_value; double radians = currentangle*Math.PI/180; ball.setX((int)((ball.getX()+10)*Math.cos(radians) + velocity*Math.cos(radians)*time)); ball.setY((int)((ball.getY()+10)*Math.sin(radians) +

Creating an animation using JApplet

由 泪湿孤枕 提交于 2019-12-24 14:28:00
问题 I am working on a Java program that uses a JApplet which makes a ball bounce up and down. I am able to paint the shape onto the JApplet and everything like that. I just can't seem to get it to move. I have looked into this and saw that I need to create a method that pauses the shape then clears it from the JApplet, changes coordinates, and then redraws the shape in the new area but for some reason it's just not working for me. Thank you in advance for the help. import java.awt.Color; import
