# WebCamTexture > WebCam Textures are textures onto which the live video input is rendered. ## Definition * **Type:** Class * **Namespace:** [UnityEngine](/engine/6000.0/script-reference/unityengine.md) * **Assembly:** UnityEngine.AudioModule * **Inherits from:** [Texture](/engine/6000.0/script-reference/unityengine/texture.md) ```csharp public sealed class WebCamTexture : Texture ``` ## Remarks On Android, iOS, and WebGL platforms, `WebCamTexture` requires the camera permission. On Android, you can request it at runtime using the [Permission](/engine/6000.0/script-reference/unityengine/android/permission.md) API. For more information, refer to [Request runtime permissions](/engine/6000.0/manual/platform-specific/android/developing/device-features-and-permissions/requesting-permissions.md) documentation. On iOS and WebGL, you can request camera permission at runtime using [Application.RequestUserAuthorization](/engine/6000.0/script-reference/unityengine/application/requestuserauthorization.md). **Note**: On Android and iOS platforms, Unity doesn't support multiple WebCamTextures simultaneously. The following code example demonstrates how to request the user for camera permission on iOS, Android, and WebGL platforms. ## Examples ```csharp using UnityEngine; using System; using System.Collections; using UnityEngine; #if UNITY_ANDROID using UnityEngine.Android; #endif public class WebCam : MonoBehaviour { #if UNITY_IOS || UNITY_WEBGL private bool CheckPermissionAndRaiseCallbackIfGranted(UserAuthorization authenticationType, Action authenticationGrantedAction) { if (Application.HasUserAuthorization(authenticationType)) { if (authenticationGrantedAction != null) authenticationGrantedAction(); return true; } return false; } private IEnumerator AskForPermissionIfRequired(UserAuthorization authenticationType, Action authenticationGrantedAction) { if (!CheckPermissionAndRaiseCallbackIfGranted(authenticationType, authenticationGrantedAction)) { yield return Application.RequestUserAuthorization(authenticationType); if (!CheckPermissionAndRaiseCallbackIfGranted(authenticationType, authenticationGrantedAction)) Debug.LogWarning($"Permission {authenticationType} Denied"); } } #elif UNITY_ANDROID private void PermissionCallbacksPermissionGranted(string permissionName) { StartCoroutine(DelayedCameraInitialization()); } private IEnumerator DelayedCameraInitialization() { yield return null; InitializeCamera(); } private void PermissionCallbacksPermissionDenied(string permissionName) { Debug.LogWarning($"Permission {permissionName} Denied"); } private void AskCameraPermission() { var callbacks = new PermissionCallbacks(); callbacks.PermissionDenied += PermissionCallbacksPermissionDenied; callbacks.PermissionGranted += PermissionCallbacksPermissionGranted; Permission.RequestUserPermission(Permission.Camera, callbacks); } #endif void Start() { #if UNITY_IOS || UNITY_WEBGL StartCoroutine(AskForPermissionIfRequired(UserAuthorization.WebCam, () => { InitializeCamera(); })); return; #elif UNITY_ANDROID if (!Permission.HasUserAuthorizedPermission(Permission.Camera)) { AskCameraPermission(); return; } #endif InitializeCamera(); } private void InitializeCamera() { WebCamTexture webcamTexture = new WebCamTexture(); Renderer renderer = GetComponent(); renderer.material.mainTexture = webcamTexture; webcamTexture.Play(); } } ``` ## Constructors | Constructor | Description | | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------- | | [WebCamTexture()](/engine/6000.0/script-reference/unityengine/webcamtexture/ctor.md#webcamtexture\(\)) | Create a WebCamTexture. | | [WebCamTexture(System.Int32,System.Int32)](/engine/6000.0/script-reference/unityengine/webcamtexture/ctor.md#webcamtexture\(int-int\)) | Create a WebCamTexture. | | [WebCamTexture(System.Int32,System.Int32,System.Int32)](/engine/6000.0/script-reference/unityengine/webcamtexture/ctor.md#webcamtexture\(int-int-int\)) | Create a WebCamTexture. | | [WebCamTexture(System.String)](/engine/6000.0/script-reference/unityengine/webcamtexture/ctor.md#webcamtexture\(string\)) | Create a WebCamTexture. | | [WebCamTexture(System.String,System.Int32,System.Int32)](/engine/6000.0/script-reference/unityengine/webcamtexture/ctor.md#webcamtexture\(string-int-int\)) | Create a WebCamTexture. | | [WebCamTexture(System.String,System.Int32,System.Int32,System.Int32)](/engine/6000.0/script-reference/unityengine/webcamtexture/ctor.md#webcamtexture\(string-int-int-int\)) | Create a WebCamTexture. | ## Properties | Property | Description | | --------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------- | | [autoFocusPoint](/engine/6000.0/script-reference/unityengine/webcamtexture/autofocuspoint.md) | This property allows you to set/get the auto focus point of the camera.
