Loading a PNG image as a texture at runtime in Unity3d

Question

I'm using a series of PNG images as sprites to create animations on a plane for an augmented reality application in Unity. The PNG images are loaded as textures, and the textures are applied to a plane to create an animation sequence that tracks with an augmented reality target. Here is the script that is attached to the plane and controls the animation sequence. File PNGSequence.js ``` #pragma strict var tecture : Texture[]; var changeInterval : float = 0.06; var isRunning = false; var isLooping = false; function Start () { var isRunning = true; } function Update () { if( isRunning == true) { Animation (); } } function Animation () { var index : int = Time.time/changeInterval; index = index % tecture.Length; renderer.material.mainTexture = tecture[index]; if ( index == tecture.Length-1){ if( isLooping == false){ isRunning = false; } renderer.material.mainTexture = tecture[0]; } } ``` Textures are assigned by drag-and-drop of PNG files in the editor and everything works fine if I limi…

Accepted Answer

In C#:

```
// Load all textures into an array
Object[] textures = Resources.LoadAll("Textures", typeof(Texture2D));

// Load a single texture
Texture2D texture = Resources.Load("Texture") as Texture2D;

renderer.material.mainTexture = texture;
```

Hope it helps. You should be able to convert it into JS no problem. Just look at the Unity documentation.
