Player攻击动画实现
Player.java部分代码
public class Player extends AttackAbleObject{ private int _leftLocked = 0; private int _rightLocked = 0; private boolean _attkKeyUp = true; private boolean _attack = false; private boolean _rdyToAttack = true; private final int _hitDelay = 320; private int _hitDelayTimer = _hitDelay; public void update(Graphics2D g){ _animator.show(g); _handleMovement(); handleAttack(); } public Transform getTransform(){ return _animator; } public void attack(){ if(_rdyToAttack){ _animator.setAnimation("attk"); _attack = true; _rdyToAttack = false; _hitDelayTimer = _hitDelay; } } void handleAttack(){ if(_attack){ _hitDelayTimer -= Config.TIMER_DIF; if(_hitDelayTimer<=0){ _rdyToAttack = true; _attack = false; _hitDelayTimer = _hitDelay; _animator.setAnimation("idle"); } } } private void _handleMovement(){ if(_input.isKeyDown(Config.PLAYER1_MELEE) && _attkKeyUp) { attack(); _attkKeyUp = false; _keyPressed = true; } if(_input.isKeyUp(Config.PLAYER1_MELEE) && !_attkKeyUp){ _attkKeyUp = true; } if(!_keyPressed && !_animator.isPlaying("idle") && !_animator.isPlaying("attk")){ _animator.setAnimation("idle"); _animator.translate(0,0); }
_handleMovement方法判断当F键被按下的时候，调用attack()方法；
attack()方法主要是设置攻击动画_animator.setAnimation("attk");
另外，update方法中调用handleAttack方法；
_hitDelayTimer = _hitDelay = 320毫秒
TIMER_DIF = 15.0毫秒
每一帧
_hitDelayTimer -= Config.TIMER_DIF;
320/15大约等于21；1秒60帧的话，攻击动画大约播放21/60=0.35秒。
