sayac.setImageDrawable(animation);
animation.start();
// play the animation when i push the play button
play.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
// pause the animation when i push pause button...
pause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
I want to pause and resume AnimationDrawable. But I can't. How can I do this?
Or can I do the same animation with ObjectAnimator or others?
If I can do the same animation with ObjectAnimator how can I do this? Is there any lesson or example?

I have two different timed Power-Ups in my project, both with 5 seconds duration. I'd like to make that if I pick a Power Up before the time ends, It makes the timer counts again from zero, but it is not happening. If I pick up the same Power UP while remaining 1 second, it lasts just for one second instead of 5. I'm using in the Player Script a public void that is called out by the Power UP when it is picked up
My Player's code:
public void TripleShotActive()
{
_canTripleShot = true;
StopCoroutine(TripleShotPowerDownRoutine());
StartCoroutine(TripleShotPowerDownRoutine());
return;
}
public void SpeedBoostPowerupActive()
{
_speedBoostActive = true;
StopCoroutine(SpeedBoostPowerDownRoutine());
StartCoroutine(SpeedBoostPowerDownRoutine());
return;
}
public void ShieldsActive()
{
_isShieldsActive = true;
_shieldVisualizer.SetActive(true);
}
IEnumerator TripleShotPowerDownRoutine()
{
yield return new WaitForSeconds(5.0f);
_canTripleShot = false;
}
IEnumerator SpeedBoostPowerDownRoutine()
{
yield return new WaitForSeconds(5.0f);
_speedBoostActive = false;
}
I tried using StopCoroutine before StartCoroutine, but it didn't work
You need to stop the coroutine earlier created by StartCoroutine.
Coroutine _tripleShotPowerDown;
public void TripleShotActive()
{
_canTripleShot = true;
if(_tripleShotPowerDown != null)
StopCoroutine(_tripleShotPowerDown);
_tripleShotPowerDown = StartCoroutine(TripleShotPowerDownRoutine());
return;
}
So I am using two push buttons (connected to an Arduino Uno) as an input to my game. The player has to push down both buttons at the same time for the character to move in the game. I want the player to hold down the buttons for a different amount of time in each level. I have a working Arduino and a working Unity timer and player script, but am not able to get the code to do what I want. What I basically want is that only when the player presses the buttons down, does the timer start counting down. Right now, the timer starts as soon as the scene begins. I know that I somehow have to reference the timer script to the button object, I have tried this but it still doesn't work. Note that the timer UI does have a Timer tag on it. I have also referenced the Player Controller script in the Timer script. Right now, Its giving me a range of errors. I have attached an image depicting these errors.error image
The Timer script:
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using UnityEngine.SceneManagement;
public class Timer : MonoBehaviour
{
//int startTime = 0;
public bool buttonPressed = false;
public int timeLeft;
public Text countdownText;
GameObject Character;
void Awake()
{
Character = GameObject.FindWithTag("Player");
}
public void Start()
{
//StartCoroutine("LoseTime");
BeginTimer();
}
void Update()
{
countdownText.text = ("Time Left = " + timeLeft);
if (timeLeft <= 0)
{
//StopCoroutine("LoseTime");
//countdownText.text = "Times Up!";
Invoke("ChangeLevel", 0.1f);
}
}
public void BeginTimer()
{
Character.GetComponent<PlayerController>().Update();
//gameObject.GetComponent<MyScript2>().MyFunction();
if (buttonPressed == true )
{
StartCoroutine("LoseTime");
}
else if (buttonPressed == false)
{
StopCoroutine("LoseTime");
}
}
IEnumerator LoseTime()
{
while (true)
{
yield return new WaitForSeconds(1);
timeLeft--;
}
}
void ChangeLevel()
{
SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex + 1);
}
}
The Player Script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.IO.Ports;
public class PlayerController : MonoBehaviour
{
SerialPort sp = new SerialPort("\\\\.\\COM4", 9600);
//player == GameObject.FindWithTag("Player").GetComponent<>();
public float Speed;
public Vector2 height;
public float xMin, xMax, yMin, yMax;
public bool buttonPressed = false;
GameObject Character;
public void Awake()
{
Character = GameObject.FindWithTag("Player");
}
public void Start()
{
if (!sp.IsOpen)
{ // If the erial port is not open
sp.Open(); // Open
}
sp.ReadTimeout = 1; // Timeout for reading
}
public void Update()
{
if (sp.IsOpen)
{ // Check to see if the serial port is open
try
{
string value = sp.ReadLine();//To("Button"); //Read the information
int button = int.Parse(value);
//float amount = float.Parse(value);
//transform.Translate(Speed * Time.deltaTime, 0f, 0f); //walk
if (button == 0) //*Input.GetKeyDown(KeyCode.Space*/) //jump
{
buttonPressed = true;
Character.GetComponent<Rigidbody2D>().AddForce(height, ForceMode2D.Impulse);
Character.GetComponent<Rigidbody2D>().position = new Vector3
(
Mathf.Clamp(GetComponent<Rigidbody2D>().position.x, xMin, xMax),
Mathf.Clamp(GetComponent<Rigidbody2D>().position.y, yMin, yMax)
);
Timer tmr = GameObject.Find("Timer").GetComponent<Timer>();
tmr.BeginTimer();
}
}
catch (System.Exception)
{
}
}
void ApplicationQuit()
{
if (sp != null)
{
{
sp.Close();
}
}
}
}
}
I think the problem may be with how I am referencing the scripts in each other.
In your timer you have a quite strange mixup of Update and Coroutine. Also note that BeginTimer is called exactly once! You also shouldn't "manually" call Update of another component.
I wouldn't use Update at all here. Simply start and stop a Coroutine.
The Timer script should only do the countdown. It doesn't have to know more:
public class Timer : MonoBehaviour
{
public int timeLeft;
public Text countdownText;
private bool timerStarted;
public void BeginTimer(int seconds)
{
// Here you have to decide whether you want to restart a timer
timeLeft = seconds;
// or if you rather want to continue counting down
//if(!timerStarted) timeLeft = seconds;
StartCoroutine(LoseTime());
}
public void StopTimer()
{
StopAllCoroutines();
}
private IEnumerator LoseTime()
{
timerStarted = true;
while (timeLeft > 0)
{
yield return new WaitForSeconds(1);
timeLeft --;
countdownText.text = $"Time Left = {timeLeft}";
}
// Only reached after the timer finished and wasn't interrupted meanwhile
// Using Invoke here is a very good idea since we don't want to interrupt anymore
// if the user lets go of the button(s) now
Invoke(nameof(ChangeLevel), 0.1f);
}
void ChangeLevel()
{
SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex + 1);
}
}
In general avoid to use Find at all. If anyhow possible already reference things in the Inspector! If needed you can use Find but only once! What you never want to do is use any of the Find and GetComponent variants repeatedly - rather store the reference the first time and re-use it - and especially not in Update no a per frame basis. They are very expensive calls!
public class PlayerController : MonoBehaviour
{
public float Speed;
public Vector2 height;
// I prefer to use Vector2 for such things
public Vector2 Min;
public Vector2 Max;
public bool buttonPressed = false;
// Already reference these via the Inspector if possible!
public Rigidbody2D Character;
public Timer timer;
public Rigidbody2D _rigidbody;
private SerialPort sp = new SerialPort("\\\\.\\COM4", 9600);
private void Awake()
{
FetchReferences();
}
// This is my "secret" tip for you! Go to the component in the Inspector
// open the ContextMenu and hit FetchReferences
// This already stores the references in the according fields ;)
[ContextMenu("FetchReferences")]
private void FetchReferences()
{
if(!Character)Character = GameObject.FindWithTag("Player"). GetComponent<Rigidbody2D>();
if(!timer) timer = GameObject.Find("Timer").GetComponent<Timer>();
}
private void Start()
{
if (!sp.IsOpen)
{
sp.Open(); // Open
}
sp.ReadTimeout = 1;
}
private void Update()
{
// I wouldn't do the serialport open check here
// your if block simply silently hides the fact that your application
// doesn't work correctly! Rather throw an error!
try
{
string value = sp.ReadLine(); //Read the information
int button = int.Parse(value);
//TODO: Since it isn't clear in your question how you get TWO buttons
//TODO: You will have to change this condition in order to only fire if both
//TODO: buttons are currently pressed!
buttonPressed = button == 0;
if (buttonPressed)
{
Character.AddForce(height, ForceMode2D.Impulse);
// The clamping of a rigidbody should always be done ine FixedUpdate!
// Pass in how many seconds as parameter or make the method
// parameterless and configure a fixed duration via the Inspector of the Timer
timer.BeginTimer(3.0f);
}
else
{
// Maybe stop the timer if condition is not fulfilled ?
timer.StopTimer();
}
}
catch (System.Exception)
{
// You should do something here! At least a Log ...
}
}
private void FixedUpdate()
{
// Here I wasn't sure: Are there actually two different
// Rigidbody2D involved? I would assume you rather wanted to use the Character rigidbody again!
Character.position = new Vector3(Mathf.Clamp(Character.position.x, Min.x, Max.x), Mathf.Clamp(Character.position.y, Min.y, Max.y));
}
// Did you mean OnApplicationQuit here?
private void ApplicationQuit()
{
if (sp != null)
{
{
sp.Close();
}
}
}
}
Typed on smartphone but I hope the idea gets clear
Below is my script, I want to check that animator state finished or not. If animator state(animation) is complete then do some action, but I am enable to do so, Thanks in advance.
using UnityEngine;
using System.Collections;
public class fun_for_level_complet : MonoBehaviour
{
public Animator animator_obj;
// Use this for initialization
void Start ()
{
}
// Update is called once per frame
void Update ()
{
check_end_state ();
}
public void level_complete()
{
if (this.GetComponent<movement_of_player> () != null)
{
this.GetComponent<movement_of_player> ().enabled = false;
}
animator_obj.SetBool ("congo",true);
}
public void check_end_state ()
{
// here I want to check if animation ends then print
// my state name is congo
// animation name Waving
// using base layer
if (animator_obj.GetCurrentAnimatorStateInfo (0).IsName ("congo") && !animator_obj.IsInTransition (0))
{
Debug.Log ("anim_done");
}
}
}
You can use events on animation clips. It's explained in Unity manual:
https://docs.unity3d.com/Manual/AnimationEventsOnImportedClips.html
In Animation Inport Settings in Annimations tab You can find Event heading. Position the playback to the end and click Add Event. Fill the Function field with name of the function to call at the end of animation. Just make sure that Game Object with this animation has a corresponding function.
I figure it out, and I done it by checking state starts or not if starts then check for end, by states names. Below is code, and working fine, remember(in last state you have to create empty state)
using UnityEngine;
using System.Collections;
public class fun_for_level_complet : MonoBehaviour
{
public Animator animator_obj;
private string[] states = new string[]{ "congo" };
private string current_state_name = "";
private bool waiting_end_state = false;
private bool wait_for_anim_start = false;
// Use this for initialization
void Start ()
{
}
// Update is called once per frame
void Update ()
{
if (waiting_end_state)
{
if (wait_for_anim_start)
{
if (animator_obj.GetCurrentAnimatorStateInfo (0).IsName (current_state_name))
{
wait_for_anim_start = false;
}
} else
{
check_end_state ();
}
}
}
public void level_complete()
{
if (this.GetComponent<movement_of_player> () != null)
{
this.GetComponent<movement_of_player> ().enabled = false;
}
animator_obj.SetBool ("congo",true);
waiting_end_state = true;
wait_for_anim_start = true;
current_state_name = states [0];
}
public void check_end_state()
{
if (!animator_obj.GetCurrentAnimatorStateInfo (0).IsName (current_state_name))
{
waiting_end_state = false;
if( current_state_name==states[0] )
{
GameObject.FindGameObjectWithTag ("inagmegui").SendMessage ("make_it_true");
print ( "animation has been ended" );
}
}
}
}
If you do not have any transitions and would like to to be notified when the animation has ended for the "stateName" in layer 0, I did by calling the following IEnumerator :
public IEnumerator PlayAndWaitForAnim(Animator targetAnim, string stateName)
{
targetAnim.Play(stateName);
//Wait until we enter the current state
while (!targetAnim.GetCurrentAnimatorStateInfo(0).IsName(stateName))
{
yield return null;
}
//Now, Wait until the current state is done playing
while ((targetAnim.GetCurrentAnimatorStateInfo(0).normalizedTime) % 1 < 0.99f)
{
yield return null;
}
//Done playing. Do something below!
EndStepEvent();
}
The main logic is once the state is entered, we should check if the fractional part of 'normalizedTime' variable reached 1, which means the animation has reached its end state.
Hope this helps
You can create custom StateMachineBehaviour like this:
using UnityEngine;
public class AttackBehaviour : StateMachineBehaviour
{
public GameObject particle;
public float radius;
public float power;
protected GameObject clone;
override public void OnStateEnter(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
{
clone = Instantiate(particle, animator.rootPosition, Quaternion.identity) as GameObject;
Rigidbody rb = clone.GetComponent<Rigidbody>();
rb.AddExplosionForce(power, animator.rootPosition, radius, 3.0f);
}
override public void OnStateExit(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
{
Destroy(clone);
}
override public void OnStateUpdate(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
{
Debug.Log("On Attack Update ");
}
override public void OnStateMove(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
{
Debug.Log("On Attack Move ");
}
override public void OnStateIK(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
{
Debug.Log("On Attack IK ");
}
}

I want to make animation moving a button from nX, nY to n1X, n1Y during 1000 ms.
My class:
public class Start extends Animation implements EntryPoint {
AbsolutePanel panel = new AbsolutePanel();
Label label;
Button b;
int a;
#Override
protected void onUpdate(double progress) {
panel.setWidgetPosition(b, 2*2, 2*2);
a++;
}
public void onModuleLoad() {
panel = new AbsolutePanel();
b = new Button("Click!");
label.setText("111");
RootPanel.get().add(label);
RootPanel.get().add(panel);
}
}
Making animation in GWT is quite easy:
Timer r1 = new Timer() {
int num = 100;
#Override
public void run() {
widget.setStyleName("after");
}
};
Timer r = new Timer() {
int num = 100;
#Override
public void run() {
widget.setStyleName("before");
num += 10;
}
};
r.scheduleRepeating(1000);
r1.scheduleRepeating(2000);`
A little introduction: I've created a simple (for now) application which uses an AnimationTimer to update animations and draw objects to the Canvas. Everything runs smoothly and the timer adjusts its fps to the refresh-rate of my laptop (50/60Hz).
When I start the program however, there seems to be something wrong which causes my animations to appear 'jurky' or dropping frames, but the framerate stays a solid 60/50fps. Then when I resize the window for the first time (no difference how many), suddenly all the animations are super-smooth. After that, everything stays 'synced' no matter the resizes done.
What is the reason that the AnimationTimerstarts 'out-of-sync' until the window is resized and can it be prevented?
Update
Added a code example. The problem is mostly visible when on 50Hz, but also exist on 60Hz. Using Eclipse on Windows 10 (first code-share, may be to much/missing things).
