how to place 3d model into canvas image unity

Place a 3D Character into UI Canvas :- 

Process of Create a canvas panel buttons - import and adjust a camera 'Aline with view' 

1. import 3d model into a unity project.
2. Drag into a hierarchy 
3. Place a camera at a side ( i mean where you want to place your character) 
4. Create a Canvas with  Panel (Create => UI => Canvas => Panel ) and expand to entire game scene then create buttons  and place another side of your Scene.

Now your unable to view your model. because the canvas occupies entire game screen
if you want to view your character you should change the canvas settings at inspector (like fig below)

In Canvas settings => Go to render mode change Screen Space - Overlay to Screen Space - Camera and choose your main camera .... Play your game

Canvas Inspector :- 

Output Game View :-

Here is your output window... now your able to see your menu or result buttons as well as animated 3d character.


Happy Scripting...

Any Queries fell free to post a comment.... 

Instantiate Prefab apply AddForce unity 2d c#

About Components (How to):-

1. Create a new project with 2D mode as shown below image.
2. First Create Empty Game Object and rename it 'ArrowImage' at Hierarchy.
3. Add Component 'Sprite Renderer' at Inspector. 
4. Import arrow image from your Window/Mac Desktop at project folder and drop it to sprite field.
5. Add Component 'Rigidbody 2D' at inspector of your arrow.
6. Save Scene and drop 'Arrow Object' to Project folder. Now it's convert into a prefab.
7. Delete your 'ArrowImage' at Hierarchy
8. Create Spawn point (where you want to release your arrow.. Probably from bow ) 
9. Add Component 'bolow script (InstantiateScript)' to spawnPoint.
10. Browse ArrowImage Prefab for InstantiateScript.
11. Play your scene... Click on you Game View.

About Script Tips:-

1. You should use LateUpdate(){} for physics iterations.

Script : -

using UnityEngine;
using System.Collections;

public class InstantiateScript : MonoBehaviour {

    public Rigidbody2D arrow1;
    public int Force = 9000;

    void LateUpdate () {
        if (Input.GetButtonDown("Fire1")) {
            
            Rigidbody2D arrowRig2D;
            arrowRig2D = Instantiate(arrow1, transform.position, transform.rotation) as Rigidbody2D;
            arrowRig2D.AddForce(-transform.right * Force * Time.deltaTime);
        }

    }
}

if you want to decrease image size at unity... you should increase Pixel Per Unit image import Settings as shown below image

zoom-in/out using two fingers mobile unity3d c sharp

About Testing :-

 * Attach below code to camera, 
 * connect your mobile through cable, 
 * make sure you should select unity remote device : Any Android Device at Editor setting
 * and Press Play 'Use your fingers to zoom in/out your screen'

About Coding :- 

 * You should store finger touches..
 * Store finger previous positions to Vector2
 * Find the magnitude... i mean current and previous delta positions
 * If the Camera projection is orthographic you should edit orthographicSize with some zoom constent 
 * If the Camera projection is Perspective you should edit fieldOfView with some zoom constent like script below
 * Happy Scripting

Code :-

using UnityEngine;
using System.Collections;


public class testZoom : MonoBehaviour
{
    public float perspectiveZoomSpeed = 0.5f;        
    public float orthoZoomSpeed = 0.5f;   
    
    
    void Update()
    {

        if (Input.touchCount == 2)
        {

            Touch touchZero = Input.GetTouch(0);
            Touch touchOne = Input.GetTouch(1);
            

            Vector2 touchZeroPrevPos = touchZero.position - touchZero.deltaPosition;
            Vector2 touchOnePrevPos = touchOne.position - touchOne.deltaPosition;
            

            float prevTouchDeltaMag = (touchZeroPrevPos - touchOnePrevPos).magnitude;
            float touchDeltaMag = (touchZero.position - touchOne.position).magnitude;
            

            float deltaMagnitudeDiff = prevTouchDeltaMag - touchDeltaMag;
            

            if (GetComponent<Camera>().orthographic)
            {
                GetComponent<Camera>().orthographicSize += deltaMagnitudeDiff * orthoZoomSpeed;
                GetComponent<Camera>().orthographicSize = Mathf.Max(GetComponent<Camera>().orthographicSize, 0.1f);
            }
            else
            {
                GetComponent<Camera>().fieldOfView += deltaMagnitudeDiff * perspectiveZoomSpeed;
                GetComponent<Camera>().fieldOfView = Mathf.Clamp(GetComponent<Camera>().fieldOfView, 0.1f, 179.9f);
            }
        }
