Just make any animation and try to use my code on it. What i'm trying to achieve is to play animation using PlayQueued multiple times, each time with different animation state for example to reverse the animation.
using UnityEngine;
using System.Collections;
public class NewBehaviourScript : MonoBehaviour {
Animation a;
void Start () {
a = animation;
Invoke("PlayAnimation3",0.3f);
}
void PlayAnimation0(){
//no problem at all...
a.PlayQueued("simpleAnimation");
a.PlayQueued("simpleAnimation");
a.PlayQueued("simpleAnimation");
}
void PlayAnimation1(){
//but when you change AnimationState...
a.PlayQueued("simpleAnimation");
AnimationState as0 = a.PlayQueued("simpleAnimation");
as0.time = as0.length;
as0.speed = -1f;
AnimationState as1 = a.PlayQueued("simpleAnimation");
//... the last AnimationState is the one that counts
as1.time = 0f;
as1.speed = 1f;
}
void PlayAnimation2(){
//making a copy of animation does not help
a.PlayQueued("simpleAnimation");
AnimationState as0 = a.PlayQueued("simpleAnimation");
as0.time = as0.length;
as0.speed = -1f;
AnimationState as1 = a.PlayQueued("simpleAnimationCopy");
as1.time = 0f;
as1.speed = 1f;
}
void PlayAnimation3(){
//it seems duplicated animations have common AnimationState...
a["simpleAnimationCopy"].time =a["simpleAnimationCopy"].length;
a["simpleAnimationCopy"].speed =-1f;
a.Play("simpleAnimation");
a.PlayQueued("simpleAnimationCopy");
a.PlayQueued("simpleAnimation");
}
void PlayAnimation4(){
//any ideas? how to use PlayQueued with different animation states?
}
}

How to turn off scene transition animations?
I would like to disable the animation ONLY for the RestartGame command. so that the animation works for other commands.
Is there any script for such a thing?
this is my animation script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
public class LevelLoader : MonoBehaviour
{
public Animator transition;
public float transitionTime = 1f;
public void LoadNextLevel()
{
StartCoroutine(LoadLevel(SceneManager.GetActiveScene().buildIndex + 1));
}
public AudioClip impact;
IEnumerator LoadLevel(int LevelIndex)
{
transition.SetTrigger("Start");
yield return new WaitForSeconds(transitionTime);
SceneManager.LoadScene(LevelIndex);
yield return new WaitForSeconds(0.3f);
AudioSource.PlayClipAtPoint(impact, transform.position);
}
}
and this is my RestartGame command which is in another script:
public void RestartGame()
{
SceneManager.LoadScene(PlayerPrefs.GetInt("SavedScene"));
}
In your actualy code, the RestartGame method don't use de animation, but if you have an animation on your scene when this starts, you can save a PlayerPref variable inside the RestartGame method before load the scene, and then check the variable before the animation.
For example:
public void RestartGame()
{
PlayerPrefs.SetInt("isRestarting",1);
SceneManager.LoadScene(PlayerPrefs.GetInt("SavedScene"));
}
then in the start of the new scene
void Start ()
{
if(PlayerPrefs.GetInt("isRestarting",0)!=1)
{
//Do the animation
}
}
You can add another option to IEnumerator that controls the animation.
IEnumerator LoadLevel(int LevelInde, bool hasAnimation = true)
{
if (hasAnimation)
{
transition.SetTrigger("Start");
yield return new WaitForSeconds(transitionTime);
}
SceneManager.LoadScene(LevelIndex);
yield return new WaitForSeconds(0.3f);
AudioSource.PlayClipAtPoint(impact, transform.position);
}
Now set it to true when restart and false to other cases. On LoadNextLevel:
StartCoroutine(LoadLevel(SceneManager.GetActiveScene().buildIndex + 1, false));
Ok, so I'm making this game where the user can drag a ball around the screen, but it's not supposed to leave the play area. I'm getting the following problem though, when I push it towards the colliders it bounces back, and if I push too hard it simply goes off screen (I need to make it do not go off screen. the user is free to drag it all over the place, but within the screen of course).
any tips on how I could solve this issue?
Here is the code for dragging which I'm using:
using UnityEngine;
using System.Collections;
public class CircleManager : MonoBehaviour {
private bool dragging = false;
private Vector3 screenPoint;
private Vector3 offset;
// Pressionando
void OnMouseDown()
{
dragging = true;
screenPoint = Camera.main.WorldToScreenPoint(gameObject.transform.position);
offset = gameObject.transform.position - Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z));
}
// Arrastando
void OnMouseDrag()
{
Vector3 cursorPoint = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z);
Vector3 cursorPosition = Camera.main.ScreenToWorldPoint(cursorPoint) + offset;
//i tried with both below.
//transform.position = cursorPosition;
transform.GetComponent<Rigidbody2D>().MovePosition(cursorPosition);
}
// Soltando
void OnMouseUp()
{
dragging = false;
}
}
Thanks!
You could try to do something like,
if( transform.position.x > xMaxPos )
{
transform.position.x = new Vector3( xMaxPos, transform.position.y, transform.position.z );
}
You could set up for each min and max. Then when you create the xMaxPos variables, create them like:
[serializeField]
private float xMaxPos;
That way they will appear in the inspector and you can tweak their values as you please. You could also throw in an offset that's the width of the ball i.e.
transform.position.x = new Vector3( xMaxPos - transform.localscale.x/2, transform.position.y, transform.position.z );
Try using velocity
public class CircleManager : MonoBehaviour {
private bool dragging = false;
private Vector3 screenPoint;
private Vector3 offset;
public float speed = 5.0f;
// Pressionando
void OnMouseDown()
{
dragging = true;
Vector3 cursorPosition = Camera.main.ScreenToWorldPoint(ToDepth(Input.mousePosition, transform.position.z));
offset = gameObject.transform.position - cursorPosition;
}
// Arrastando
void OnMouseDrag()
{
Vector3 cursorPosition = Camera.main.ScreenToWorldPoint(ToDepth(Input.mousePosition, transform.position.z)) + offset;
Vector3 direction = (transform.position - cursorPosition).normalized;
transform.GetComponent<Rigidbody2D>().velocity = direction * speed * Time.deltaTime;
}
// Soltando
void OnMouseUp()
{
dragging = false;
}
Vector3 ToDepth(Vector3 value, float depth)
{
return new Vector3(value.x, value.y, depth);
}
}
Few things to note:
You don't have to write out gameObject.transform.position i see you did that a few times, as well as calling transform... directly. Its both the same thing, so you don't need the gameObject part.
Also your getting the screenPoint of the transform, then using the z value of that later on, which doesn't really make much sense to me.
Anyways, i don't see why this shouldn't work for you, i haven't tested it though.
I want to make a TextView appear little by little, like animation. The problem is, the animation is not smooth. It gets stuck for a little while sometimes and then resumes. Sometimes even worse, it goes back... I mean, the TextView gets bigger and bigger but suddenly gets smaller then bigger again. Could anyone help me?

ViewGroup.LayoutParams pa = view.getLayoutParams();
while (pa.height < maxHeight[0]) {
pa.height += (int) (24 * getResources().getDisplayMetrics().density + 0.5f);
sleep(100);
publishProgress(pa.height);
}
return maxHeight[0];
}
private void sleep(int i) {

Thread.sleep(i);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
#Override

ViewGroup.LayoutParams pa = view.getLayoutParams();
pa.height = values[0];
view.setLayoutParams(pa);
}
#Override

ViewGroup.LayoutParams pa = view.getLayoutParams();
pa.height = result;
view.setLayoutParams(pa);
}
}
You should be using a scale animation for this. Here's an example:
ScaleAnimation animation = new ScaleAnimation(1, 2, 1, 2, centerX, centerY); // Scales from normal size (1) to double size (2). centerX/Y is the center of your text view. Change this to set the pivot point of your animation.
animation.setDuration(1000);
myTextView.startAnimation(animation);
You can use droidQuery to simplify this:
//this will set the height of myView to 0px.
$.with(myView).height(0);
//when you are ready to animate to height (in pixels):
$.with(myView).animate("{height:" + height + "}", new AnimationOptions());
Check the documentation if you want to get fancy - such as adding duration, and event callbacks. If you are still noticing non-smooth animation, consider adding the application attribute to your AndroidManifest:
android:hardwareAccelerated="true"
This is the view that appears when I click a button on a previous view.
The text boxes, the smiling face image and the labels are predesigned created by xCode.
Please see the image and the code of the view to clear why all the view's components are initializing very slowly and getting ready to give the last shoot that is captured by me when it is finished to be totally loaded . Moreover, It is very slow when I type letters, the letters are appearing very slowly while I am typing with the keyboard that iOS provides on every touch on the text box.

This does not look to be initialization related. You are adding notifications from both ViewDidAppear and ViewWillAppear. You're also always calling ResetTheView, which does animations, on every keyboard notification (even if nothing else changed).
My guess is that you are calling ResetTheView way more often that you realize - and the continuous animations are killing the performance of your application.
You can confirm this by putting a Console.WriteLine, and maybe a counter, in the ResetTheView method.
I'm new to Windows Forms, in my project, i need to change the image in the picture box at runtime. I'm able to do that with the help of a timer. The picture just gets changed. Is it possible to do some transitions when image changes, for example fade in, fade out, blur etc.. If possible could some one please let me know how to do it. I searched in net but in vain.Thanks in advance.

Build your project. You can now drop a BlendPanel from the top of the toolbox onto your form. Here's a sample program that uses it:
private float mBlend;
private int mDir = 1;
public int count = 0;
public Bitmap[] pictures;
public void myPhoto()
{
pictures = new Bitmap[9];
pictures[0] = new Bitmap(#"Library Images\cf3.jpg");
pictures[1] = new Bitmap(#"Library Images\cf4.jpg");
pictures[2] = new Bitmap(#"Library Images\l1.JPG");
pictures[3] = new Bitmap(#"Library Images\l2.JPG");
pictures[4] = new Bitmap(#"Library Images\l3.JPG");
pictures[5] = new Bitmap(#"Library Images\l4.JPG");
pictures[6] = new Bitmap(#"Library Images\l5.JPG");
pictures[7] = new Bitmap(#"Library Images\l6.JPG");
pictures[8] = new Bitmap(#"Library Images\l7.JPG");
timer1.Interval = 50; //time of transition
timer1.Tick += BlendTick;
try
{
blendPanel1.Image1 = pictures[count];
blendPanel1.Image2 = pictures[++count];
}
catch
{
}
timer1.Enabled = true;
}
private void BlendTick(object sender, EventArgs e)
{
mBlend += mDir * 0.02F;
if (mBlend > 1)
{
mBlend = 0.0F;
if ((count + 1) < pictures.Length)
{
blendPanel1.Image1 = pictures[count];
blendPanel1.Image2 = pictures[++count];
}
else
{
blendPanel1.Image1 = pictures[count];
blendPanel1.Image2 = pictures[0];
count = 0;
}
}
blendPanel1.Blend = mBlend;
}
You'll need to modify the new Bitmap(#"yourimagePath"); calls. Build and run. You should see the displayed image smoothly morph from your first image to your second image without any flickering.
I hope it helps for other...
There is no built-in support for such effects, but you can implement them. I'd suggest to write a custom control that renders the image and have a method for fade-swap, fade itself can be reached with alpha-blending drawing with .NET Graphics class.
However, Graphics class isn't very fast, I don't recommend to use this technique for big images. If you need some fancy UI with hw-accelerated effects, take a look at WPF.
Blend effects are easy to get going by using the ColorMatrix class. There's a good example available in my answer in this thread.
A simple way to get a blur is to resize the image, making it smaller, then redraw it back, making it larger. The Graphics.InterpolationMode property affects the type of blur you'll get.
Those are quicky do-it-yourself solutions. Any decent graphics library has these kind of operations built-in. You probably want something free, check out ImageMagick.NET
To put it simply, not without external (3rd-party) libraries.
