私はJavaで基本的な落下砂ゲームを作成しようとしています。各パーティクルには、XとYがポイント配列に格納されています。各Point配列はその要素に固有であるため、砂と水は2つの異なる配列です。私が知りたいのは、砂の配列をそれ自体に対してチェックして、2つの粒子が同じ位置にあるかどうかを確認し、同じ位置にある場合はそれらを移動する方法です。 ？
これは私の砂のクラスです
package testingzone;
import java.awt.Point;
import java.util.Stack;
import org.newdawn.slick.Graphics;
import org.newdawn.slick.SlickException;
public class Sand {
public Graphics g = new Graphics();
public float sizeX = 1;
public float sizeY = 1;
public int speed = 1;
public String BaseState = "fall";
public String state = "fall";
public String Name = "Sand";
public Point[] point = new Point[(600 * 800)];
public Point[] pointcheck = new Point[(600 * 800)];
public int num = 0;
public boolean check = false;
public org.newdawn.slick.Color c = org.newdawn.slick.Color.yellow;
public void drawParticle(float x, float y) throws SlickException{
g.setColor(c);
g.drawRect(x, y, sizeX, sizeY);
}
public void createParticle() throws SlickException{
if(state == "fall"){
fall(point);
} else {
}
if(state == "stay"){
stay(point);
} else {
}
}
public void fall(Point[] point) throws SlickException{
for (int index = 0; index < point.length; index++) {
Point p = point[index];
if (p != null) {
if (p.y >= 598) {
drawParticle(point[index].x, 598);
} else {
drawParticle(p.x, p.y);
p.y += speed;
}
}
}
}
public void stay(Point[] point) throws SlickException{
for (int index = 0; index < point.length; index++) {
Point p = point[index];
if (p != null) {
drawParticle(p.x, p.y);
}
}
}
}
そしてこれは私のメインクラスの簡略版です
