新增功能

杀敌数量显示

Person添加killNum属性记录杀敌数量

Frame.java

//  绘画时间graphics.drawString("时间 " + (dif/1000/60) + " : " + (dif/1000%60), 600, 60);

跳跃可攻击

Person.java

public void attack() {      //  攻击if (this.status > 0) {this.status = 4;}else {this.status = -4;}}
public void applyGravity() {    //  落地方法if (this.y < 250) {double GRAVITY = 0.5;this.veloctiyY += GRAVITY;this.y += (int)this.veloctiyY;if (this.y >= 250) {this.y = 250;this.veloctiyY = 0;}}}

跳跃可转身

Person.java

private boolean jumpDirectionChangeRequested = false;   //  跳跃时的方向改变请求public void setJumpDirectionChangeRequested(boolean jumpDirectionChangeRequested) {this.jumpDirectionChangeRequested = jumpDirectionChangeRequested;}public void setJumpMoveDirection(int jumpMoveDirection) {this.jumpMoveDirection = jumpMoveDirection;}private void moveXY() {     //  人物移动方法switch (status) {case 1:     //  向右-站立break;case 2:     //  向右-跑x += 10;break;case 3:     //  向右-跳跃if (this.jumpMoveDirection > 0) {x += 10;}else if (this.jumpMoveDirection < 0) {x -= 10;}y -= jumpForce + 2;if (y > 250) {y = 250;if (this.jumpMoveDirection > 0) {this.status = 2;} else if (this.jumpMoveDirection < 0) {this.status = -2;}else {this.status = this.status > 0 ? 1 : -1;}}jumpForce--;break;case 4:     //  向右-攻击break;case -1:    //  向左-站立break;case -2:    //  向左-跑x -= 10;break;case -3:    //  向左-跳跃if (this.jumpMoveDirection > 0) {x += 10;}else if (this.jumpMoveDirection < 0) {x -= 10;}y -= jumpForce + 2;if (y > 250) {y = 250;if (this.jumpMoveDirection > 0) {this.status = 2;} else if (this.jumpMoveDirection < 0) {this.status = -2;}else {this.status = this.status > 0 ? 1 : -1;}}jumpForce--;break;case -4:    //  向左-攻击break;default:break;}}

Frame.java

@Override       //  按下某个键时调用public void keyPressed(KeyEvent e) {int keyCode = e.getKeyCode();if (keyCode == 68) {    // 按下D时右跑this.person.rightRun();}if (keyCode == 65) {    // 按下A时左跑this.person.leftRun();}if (keyCode == 75) {    // 按下K时跳跃this.person.jump();}if (keyCode == 74) {    // 按下J时攻击this.person.attack();}if (keyCode == 76) {    // 按下L时闪现this.person.flash();}//  当按下A或D键且人物处于跳跃状态时，设置方向改变请求为trueif (person.getStatus() == 3 || person.getStatus() == -3) {if (keyCode == 68) {person.setJumpDirectionChangeRequested(true);person.setJumpMoveDirection(1);} else if (keyCode == 65) {person.setJumpDirectionChangeRequested(true);person.setJumpMoveDirection(-1);}}}

闪现

Person.java

public void flash() {   //  闪现if (this.status == 1 || this.status == 2) {this.x += 100;}else if (this.status == -1 || this.status == -2) {this.x -= 100;}}
