So I figured by myself (supposedly) how to make the attack animation cycle all the way through after pressing a key without needing to keep it pressed. But now it doesn't always start at the same frame index and sometimes doesn´t even complete the animation (as you will see, sometimes it does). Heres a gif of what's going on.
These go in the constructor
aR = new Animation(50, Assets.aRight);
aL = new Animation(50, Assets.aLeft);
aF = new Animation(50, Assets.aFront);
aB = new Animation(50, Assets.aBack);
I use this timer to keep track of the cooldown and also set the flag (timerFlag) that indicates the start of the attack animation to true.
attackTimer += System.currentTimeMillis() - lastAttackTimer;
lastAttackTimer = System.currentTimeMillis();
if(attackTimer < attackCooldown){
timerFlag = false;
return;
}
if(!handler.getKeyManager().attack)
return;
timerFlag = true;
(after a little bit of code attackTimer is set to 0)
To decide what the game will render I use an int (stillLock) that saves the last direction the player faced and I have a second static flag that indicates that the animation started. (I even reset the index every time it starts just to make sure *sadface)
else if(timerFlag&&!animCd){
switch (stillLock){
case 1: //to attack
animCd = true;
timerFlag = false;
aL.setIndex(0);
return aL.getCurrentFrame();
case 2:
animCd = true;
timerFlag = false;
aR.setIndex(0);
return aR.getCurrentFrame();
case 3:
animCd = true;
timerFlag = false;
aB.setIndex(0);
return aB.getCurrentFrame();
case 4:
animCd = true;
timerFlag = false;
aF.setIndex(0);
return aF.getCurrentFrame();
}
}
else if(animCd){
switch (stillLock){
case 1: //to finish attack animation
aL.tick();
return aL.getCurrentFrame();
case 2:
aR.tick();
return aR.getCurrentFrame();
case 3:
aB.tick();
return aB.getCurrentFrame();
case 4:
aF.tick();
return aF.getCurrentFrame();
}
And this is the Animation class where the magic happens
public class Animation {
private int speed, index;
private long lastTime, timer;
private BufferedImage[] frames;
public Animation(int speed, BufferedImage[] frames){
this.speed = speed;
this.frames = frames;
index = 0;
lastTime = System.currentTimeMillis();
timer = 0;
}
public void tick(){
timer += System.currentTimeMillis() - lastTime;
lastTime = System.currentTimeMillis();
if(timer > speed){
index++;
timer = 0;
if(index >= frames.length){
index = 0;
Player.animCd = false;
}
}
}
public BufferedImage getCurrentFrame(){
return frames[index];
}
public void setSpeed(int speed){
this.speed = speed;
}
public void setIndex(int index){
this.index = index;
}
}
And finally it renders like this.
public void render(Graphics g)
{
g.drawImage(getCurrentAnimationFrame(), (int) (x - handler.getGameCamera().getxOffset()),
(int) (y - handler.getGameCamera().getyOffset()), width, height, null);
}
I'm trully sorry for the code dump, I swear I worked hard narrowing it down only to the important stuff and being specific. Hope you can help me, I've been stuck with this for weeks... :)
