如何添加碰撞檢測的死亡特徵？

Question

（注意：從遊戲開發這個職位是複製粘貼，因爲我得到的評論說，在堆棧溢出發佈此）

我想要的是，當我的球員與我的瓷磚碰撞（這是固體）他們」將被髮送到menustate（或menuscreen）。我已經爲我的瓷磚進行了碰撞檢測（使用isSolid）。所以，如果我的玩家碰到一塊磚塊（那塊磚塊是堅實的），它會被髮送給我的組合單位。

對不起，如果我添加不需要的類，它的我的玩家，生物和實體類相互延伸。

這是我的碰撞檢測存在的生物類。

public abstract class Creatures extends Entity { 

public static final int DEFAULT_HEALTH = 1; 
public static final float DEFAULT_SPEED = 5.0f; 
public static final int DEFAULT_CREATURE_WIDTH = 128; 
public static final int DEFAULT_CREATURE_HEIGHT = 128; 

protected int health; 
protected float speed; 
public static float xMove; 
public static float yMove; 
protected int MinHeight; 

public Creatures(Handler handler, float x, float y, int width, int height) { 
    super(handler, x, y, width, height); 
    health = DEFAULT_HEALTH; 
    speed = DEFAULT_SPEED; 
    xMove = 0; 
    yMove = 0; 
    MinHeight = -1; 
} 

public void move(){ 
    moveX(); 
    moveY(); 
} 

//COLLISION DETECTION BELOW 
public void moveX(){ 
    if(xMove > 0){//Moving right 
     int tx = (int) (x + xMove + bounds.x + bounds.width)/Tile.TILEWIDTH; 

     if(!collisionWithTile(tx, (int) (y + bounds.y)/Tile.TILEHEIGHT) && 
       !collisionWithTile(tx, (int) (y + bounds.y + bounds.height)/Tile.TILEHEIGHT)){ 
      x += xMove; 
     }else{ 
      x = tx * Tile.TILEWIDTH - bounds.x - bounds.width - 1; 
     } 

    }else if(xMove < 0){//Moving left 
     int tx = (int) (x + xMove + bounds.x)/Tile.TILEWIDTH; 

     if(!collisionWithTile(tx, (int) (y + bounds.y)/Tile.TILEHEIGHT) && 
       !collisionWithTile(tx, (int) (y + bounds.y + bounds.height)/Tile.TILEHEIGHT)){ 
      x += xMove; 
     }else{ 
      x = tx * Tile.TILEWIDTH + Tile.TILEWIDTH - bounds.x; 
     } 
    } 
} 

public void moveY(){ 
    if(yMove < 0){//Up 
     int ty = (int) (y + yMove + bounds.y)/Tile.TILEHEIGHT; 

     if(!collisionWithTile((int) (x + bounds.x)/Tile.TILEWIDTH, ty) && 
       !collisionWithTile((int) (x + bounds.x + bounds.width)/Tile.TILEWIDTH, ty)){ 
      y += yMove; 
     }else{ 
      y = ty * Tile.TILEHEIGHT + Tile.TILEHEIGHT - bounds.y; 
     } 

    }else if(yMove > 0){//Down 
     int ty = (int) (y + yMove + bounds.y + bounds.height)/Tile.TILEHEIGHT; 

     if(!collisionWithTile((int) (x + bounds.x)/Tile.TILEWIDTH, ty) && 
       !collisionWithTile((int) (x + bounds.x + bounds.width)/Tile.TILEWIDTH, ty)){ 
      y += yMove; 
     }else{ 
      y = ty * Tile.TILEHEIGHT - bounds.y - bounds.height - 1; 
     } 
    } 
} 

//This code below checks if the tile im colliding is Solid or not 
protected boolean collisionWithTile(int x, int y){ 
    return handler.getWorld().getTile(x, y).isSolid(); 
} 

//GETTERS AND SETTERS 

public float getxMove() { 
    return xMove; 
} 

@SuppressWarnings("static-access") 
public void setxMove(float xMove) { 
    this.xMove = xMove; 
} 

public float getyMove() { 
    return yMove; 
} 

@SuppressWarnings("static-access") 
public void setyMove(float yMove) { 
    this.yMove = yMove; 
} 

public int getHealth() { 
    return health; 
} 

public void setHealth(int health) { 
    this.health = health; 
} 

public float getSpeed() { 
    return speed; 
} 

public void setSpeed(float speed) { 
    this.speed = speed; 
} 

} 

然後我的實體類（我的生物類擴展到這一類）

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

public abstract class Entity { 

protected Handler handler; 
protected float x, y; 
protected int width, height; 
protected Rectangle bounds; 

public Entity(Handler handler, float x, float y, int width, int height){ 
    this.handler = handler; 
    this.x = x; 
    this.y = y; 
    this.width = width; 
    this.height = height; 

    bounds = new Rectangle(0, 0, width, height); 
} 

public abstract void tick(); 

public abstract void render(Graphics g); 

public float getX() { 
    return x; 
} 

public void setX(float x) { 
    this.x = x; 
} 

public float getY() { 
    return y; 
} 

public void setY(float y) { 
    this.y = y; 
} 

public int getWidth() { 
    return width; 
} 

public void setWidth(int width) { 
    this.width = width; 
} 

public int getHeight() { 
    return height; 
} 

public void setHeight(int height) { 
    this.height = height; 
} 

} 

我的播放器類（我的播放器類擴展到我的生物類）

import java.awt.Graphics; 
import java.awt.image.BufferedImage; 

public class Player extends Creatures{ 

//Animations 
private Animation animRight, animLeft; 

public Player(Handler handler, float x, float y) { 
    super(handler, x, y, Creatures.DEFAULT_CREATURE_WIDTH, Creatures.DEFAULT_CREATURE_HEIGHT); 

    bounds.x = 32; 
    bounds.y = 32; 
    bounds.width = 92; 
    bounds.height = 96; 

    //Animations 
    animRight = new Animation(100, Assets.DerpDino_right); 
    animLeft = new Animation(100, Assets.DerpDino_left); 
} 

@Override 
public void tick() { 

    //Animations 
    animRight.tick(); 
    animLeft.tick(); 
    //Movement 
    getInput(); 
    move(); 
    handler.getGameCamera().centerOnEntity(this); 

} 

@SuppressWarnings("unused") 
private void Dead(){ 
    //what to put in here 
} 

private void getInput(){ 
    xMove = 6; 
    //Gravity 
    yMove = 6; 
    MinHeight = 0; 

    if(handler.getKeyManager().left) 
     xMove = -speed; 
    if(handler.getKeyManager().right) 
     xMove = speed; 
    if(handler.getKeyManager().jumping) 
     //this makes my player fly 
     yMove = -speed; 
} 

@Override 
public void render(Graphics g) { 
    g.drawImage(getCurrentAnimationFrame(), (int) (x - handler.getGameCamera().getxOffset()), (int) (y -handler.getGameCamera().getyOffset()), width, height, null);  


private BufferedImage getCurrentAnimationFrame(){ 
    if(xMove < 0){ 
     return animLeft.getCurrentFrame(); 
    }else{ 
     return animRight.getCurrentFrame(); 
    } 
} 

} 

瓷磚類（ isSolid（）is）

import java.awt.Graphics; 
import java.awt.image.BufferedImage; 

public class Tile { 

//STATIC STUFF HERE 

public static Tile[] tiles = new Tile[256]; 
public static Tile grassTile = new GrassTile(0); 
public static Tile cactusTile = new CactusTile(1); 
public static Tile dirtTile = new DirtTile(2); 
public static Tile skyTile = new SkyTile(3); 
public static Tile cloudTile = new CloudTile(4); 
public static Tile caveTile = new CaveTile(5); 
public static Tile stoneTile = new StoneTile(6); 

//CLASS 

public static final int TILEWIDTH = 128, TILEHEIGHT = 128; 

protected BufferedImage texture; 
protected final int id; 

public Tile(BufferedImage texture, int id){ 
    this.texture = texture; 
    this.id = id; 

    tiles[id] = this; 
} 

public void tick(){ 

} 

public void render(Graphics g, int x, int y){ 
    g.drawImage(texture, x, y, TILEWIDTH, TILEHEIGHT, null); 
} 

//HERE!! 
public boolean isSolid(){ 
    return false; 
} 

public int getId(){ 
    return id; 
} 

} 

Answer 1

得到了答案！我只是在我的播放機與塊碰撞添加State.setstate(menustate)，找到我的代碼//這裏。

public boolean moveX(){ 
    if(xMove > 0){//Moving right 
     int tx = (int) (x + xMove + bounds.x + bounds.width)/Tile.TILEWIDTH; 

     if(!collisionWithTile(tx, (int) (y + bounds.y)/Tile.TILEHEIGHT) && 
       !collisionWithTile(tx, (int) (y + bounds.y + bounds.height)/Tile.TILEHEIGHT)){ 
      x += xMove; 
     }else{ 
      x = tx * Tile.TILEWIDTH - bounds.x - bounds.width - 1; 
      State.setState(handler.getGame().menuState);//here!!! 
     } 

    }else if(xMove < 0){//Moving left 
     int tx = (int) (x + xMove + bounds.x)/Tile.TILEWIDTH; 

     if(!collisionWithTile(tx, (int) (y + bounds.y)/Tile.TILEHEIGHT) && 
       !collisionWithTile(tx, (int) (y + bounds.y + bounds.height)/Tile.TILEHEIGHT)){ 
      x += xMove; 
     }else{ 
      x = tx * Tile.TILEWIDTH + Tile.TILEWIDTH - bounds.x; 
      State.setState(handler.getGame().menuState);//here!!! 
     } 
    } 
    return false; 
} 

public boolean moveY(){ 
    if(yMove < 0){//Up 
     int ty = (int) (y + yMove + bounds.y)/Tile.TILEHEIGHT; 

     if(!collisionWithTile((int) (x + bounds.x)/Tile.TILEWIDTH, ty) && 
       !collisionWithTile((int) (x + bounds.x + bounds.width)/ Tile.TILEWIDTH, ty)){ 
      y += yMove; 
     }else{ 
      y = ty * Tile.TILEHEIGHT + Tile.TILEHEIGHT - bounds.y; 
      State.setState(handler.getGame().menuState);//here!!! 
     } 

Answer 2

您必須創建一個名爲STATE的枚舉，它將包含並處理您的遊戲狀態。

public enum STATE {GAME, MENU}; 
public STATE state = STATE.GAME; 

在你的遊戲循環中，你必須實現if語句。

if (state == STATE.GAME) { 
    // game logic here 
} else if (state == STATE.MENU) { 
    // menu logic here 
} 

也不要忘了在你的圖形添加這些，當狀態設置爲遊戲，當它被設置爲菜單什麼什麼應該呈現。

那麼你應該叫：

if (collisionWithTile) { 
    state = STATE.MENU; 
}
