Play Video streaming in unity3D iphone.

Hi all,

 All are having need to put cut scenes or video about their game. So, here we lets look about the simple script to play video in unity iPhone games.

Needs :

 Unity3d iOS pro.

 steps :

 1. Create a folder in Project View. and store the name as "StreamingAssests".
 2. Place your video inside of the folder.

 That's it.
 After that you need to play the video before menu gets load. So, need to write this script into void Start() (in .cs) or function Start() (in .js) of the menu script.

 Here the Script :

 iPhoneUtils.PlayMovie("Video.mp4", Color.clear, iPhoneMovieControlMode.CancelOnTouch, iPhoneMovieScalingMode.AspectFill);

 Video.mp4 // Name of your Video.

Note : When you click on video while playing it'll cancel and menu 'll come automatically.

One easier cake enjoy:-)

Pinch zoom and swipe camera movements in unity3d for Iphone

Hi guys,
  This post is regarding to "pinch zoom and swipe movements for iPhone". I have just searched for all unity forums about pinch zoom and swipe movements in a same script. And here the script about this,

Its C# Script : (Touches.cs)

Note : i took Z-axis (right to left movements) , X-axis (front to back movements) 

using UnityEngine;
using System.Collections;

public class Touches : MonoBehaviour
{
public float minDist = 2.0f;
public float maxDist = 5.0f;
public Transform projectile;
public float speed;
private Vector3 moveVec;
private float startZ;
private float actualDist;
       
void Start ()
{       
    startZ = projectile.position.z;
}
   
void Update ()
{

//This section for move the camera position only limited values . 

// You can Change the values for your requirements.

//Here the camera will move with in your required portion on the screen.

if(projectile.position.z >= 100)
{           
transform.position = transform.position + new Vector3(0.0f,0.0f,-10.0f);
}
else if(projectile.position.z <= -150)
{
transform.position = transform.position + new Vector3(0.0f,0.0f,10.0f);
}
       
if(projectile.position.y >= 140)
{
transform.position = transform.position + new Vector3(0.0f,-10.0f,0.0f);
}
else if(projectile.position.y <= -50)
{
transform.position = transform.position + new Vector3(0.0f,10.0f,0.0f);
}
       
if(projectile.position.x >= 420)
{
transform.position = transform.position + new Vector3(-5.0f,0.0f,0.0f);
}
else if(projectile.position.x <= 85)
{
transform.position = transform.position + new Vector3(5.0f,0.0f,0.0f);
}

// This Section For to move camera according to your swipe on screen.       
if (Input.touchCount == 1 )
{               
Touch touch = Input.GetTouch(0);
switch (touch.phase)
{
case TouchPhase.Began:
dragStartPos = touch.position;
moveVec = Vector2.zero;
break;
           
case TouchPhase.Moved:
Vector3 pos = Camera.main.ScreenToWorldPoint(touch.position);
pos.z = startZ;
projectile.position = Camera.main.ScreenToWorldPoint(touch.position);
//here i gave condition to move camera with in required position
if(projectile.position.z >= -150 && projectile.position.z <= 100)
{
moveVec = -(touch.position - dragStartPos) * speed;
}
break;
           
case TouchPhase.Ended:
dragStartPos = touch.position;
moveVec = Vector2.zero;
break;
}
projectile.Translate(moveVec * Time.deltaTime);
Vector3 val = moveVec * Time.deltaTime;
}

//This section for pinch Zooming on screen.       
if (Input.touchCount == 2)
{
Touch touch = Input.GetTouch(0);
Touch touch1 = Input.GetTouch(1);
if (touch.phase == TouchPhase.Moved && touch1.phase == TouchPhase.Moved)
{
Vector2 curDist = touch.position - touch1.position;
Vector2 prevDist = (touch.position - touch.deltaPosition) - (touch1.position - touch1.deltaPosition);
float delta = curDist.magnitude - prevDist.magnitude;
Camera.main.transform.Translate(0,0,delta * .5f);
}
}
}

Its simple and make it use guys.

problems when build unity3d projects for iphone

Hi guys,

Before i have entered into this title, i need to say something...i got lot problems when i build my unity projects in to xcode.. there is no documents and clear ideas for beginner to buid their game in unity for iphone..

Boring?? ok we may enter now...

1. Before you start games for iphone in unity you need to know what are all the points will support and wont support in iphone... so all the beginners in unity and experienced should refer this first..http://unity3d.com/support/documentation/Manual/iphone-GettingStarted.html

2. First drawback i faced was Unity Terrains wont be support in IPhone. Because of unity terrains are showing real time basis. so the memory should be very high. It'll be one of the reason iphone should not accept it.

3. You cant use OnMouseDown(),OnMouseEnter(),OnMouseOver(),OnMouseExit(),OnMouseDrag(),OnMouseUp() functions for iPhone...you may use "Input.GetMouseButtonDown(0) and Input.GetMouseButtonUp(0)" instead for that kind of functions. you must done it with raycast for touch or click for both iPhone and webplayers.

4. After you have done the project you must set the correct player settings for ios. if you not enter the correct details in player settings surely you'll get these kind of errors in xcodes. i have asked questions about the errors which i have faced in this kind of mistake. see this link http://forum.unity3d.com/threads/79530-Bunch-of-errors-when-build-unity-in-xCode and you may check this link also http://forum.unity3d.com/threads/78305-Xcode-simulator-error. and dont get confuse with native plugins.. we may not use it.

    The errors will come like this..in "Xcode"
   a) RegisterAllStrippedInternalCalls() in RegisterMonoModules.o

   b) If you add the native plugin program in to your unity project you'll get error like
      error: 'mono_dl_register_symbol' was not declared in this scope.

   c) "_FooPluginFunction", referenced from:
         _FooPluginFunction$non_lazy_ptr in RegisterMonoModules.o
         (maybe you meant: _FooPluginFunction$non_lazy_ptr)
         ld: symbol(s) not found
         collect2: ld returned 1 exit status

 So,dont add the native plugin for unwanted reason. the reason has clearly mentioned in this link
http://unity3d.com/support/documentation/Manual/Plugins.html#iPhonePlugins

5. Solutions for these kind Of problems are: 
    a)  you must enter correct player settings in Unity -> File -> BuildSettings -> Player Settings..

    b) first you may check and select the static batching and uncheck the dynamic batching...

    c) give the correct target ios verson..

    d) give the correct platform you want to run unity. Because unity 3.0 wont run and work with simulator. you need to upgrade to unity 3.2.

    e) Choose the current ios verson 4.0 or 4.1 or 4.2 anything.

    f) Use always .Net 2.0 for compability.

    g) set target platform to universal arvm6.0(openGl 2.0).

Now you may run your project. it'll build successfully.

Finally if you want optimize your project refer this page http://unity3d.com/support/documentation/Manual/iphone-playerSizeOptimization.html

Thank you,
Sriram.

2.add and destroy GameObjects using "Tag" ......

hey guys,
1. ADD TAGS TO THE GAMEOBJECT:

dont add tag when create instantiate...the alternative way is better...you may change the existing tag instead for that...by example consider your prefab tag name as "man"...
assume if you want to instantiate 5 man and you want to tag it as "man1,man2,....man5" means you may do the script like this,

int k =1;
for(int j=1; j<=5; j++)
{
GameObject clone=Instantiate(prefab,someObject.transform

.position,Quaternion.identity) as GameObject; 

clone.transform.tag = "man"+k;
k++;
}

its very simple....here the tag name will be assigned......

2.Destroy using Tag Name:

 its simple to destroy it.....

Destroy(GameObject.FindWithTag(something.tag));

1.Find the Parent Object name using child in unity3d

if you want to get the parent object name means,

Assume,your parent object name as, Man....it have child name as hand...

GameObject ParentName = GameObject.Find("hand").transform.parent.gameObject;

Debug.Log("parent name :  "+ParentName.name);

it'll give your parent Object name as man....it'll really helpful when you find objects name in runtime.
