Hey Ive got some problems with a shooting game I want to be able to shoot multible shoots from my canon, As it is now I can just fire once and then I have to reset the whole project. I think Im doing something wrong in my fire method in the while loop.
Appreciating any tips!
public class Ball extends Actor
{
private double X;
private double Y;
private double length;
private double theta;
private double startVelX;
private double startVelY;
private double curVelY;
private double g;
private double ballAngle;
private double dt;
public Ball CanonBall;
private Target target;
public Ball()
{
GreenfootImage canonball = new GreenfootImage(10,10);
canonball.setColor(Color.BLACK);
canonball.fillOval(0, 0, 15, 15);
setImage(canonball);
}
public void act()
{
Angel();
setBallAngle();
fire();
}
public void Angel()
{
CanonWorld world = (CanonWorld) getWorld();
Canon canon = world.getCanon();
theta = canon.getAngle();
if( Greenfoot.isKeyDown("1"))
{
length = 10.0;
}
if( Greenfoot.isKeyDown("2"))
{
length = 22.0;
}
if( Greenfoot.isKeyDown("3"))
{
length = 32.0;
}
startVelX = length*Math.cos(theta);
startVelY = length*Math.sin(theta);
curVelY = startVelY;
g = 0.5;
X = getX();
Y = getY();
}
public void setBallAngle()
{
ballAngle = Math.toDegrees(Math.atan2(-1*curVelY,startVelX));
}
public void fire()
{
if (Greenfoot.mouseClicked(null))
while (dt < 8)
{
setBallAngle();
X = X + startVelX;
Y = Y - curVelY;
setLocation((int) X, (int) Y);
Greenfoot.delay(2);
curVelY = curVelY - g;
dt += .01;
checkCollision();
}
}
