Creating sprite from texture atlas

Question

In my libGdx project,I created a sprite from texture atlas,using createSprite(). I want to implement the sprite as rotated. How can I do it?Here is my Code:

 reelSprite = atlas.createSprite("reel");

Inside render():

for (Wall lWalls : leftWalls){
        reelSprite.setOrigin(lWalls.getX(), lWalls.getY());
        reelSprite.setRotation(180);

    batch.draw(reelSprite, lWalls.getX(), lWalls.getY());
    }

This code is not working.Please tell me what wrong I did.

Please try to achieve your goals yourself first before asking a question. Then, in the question explain what you tried, with code preferably, and what's not working. — DavidS, Dec 01 '16 at 18:57

You should use setRotation before you draw the sprite:

And even before that set rotation point:

I tried both setRotation() and setOrigin() .But no effect. – Niranjana Dec 02 '16 at 05:25
Hmm...I didn't use the sprites, but textures and they are rotating just fine. – MilanG Dec 02 '16 at 08:04

float rotate = 0;
rotate += (sprite.getRotation() - 40) * Gdx.graphics.getDeltaTime();
      if(Math.abs(rotate) > 10) // change the number to set the rotation power cap
            {
                rotate = -10;
            }
   sprite.rotate(rotate);

I am moving the reelSprite.Is that the reason rotation not working on the sprite? – Niranjana Dec 05 '16 at 04:44

I changed the code like this...

for (Wall lWalls : leftWalls){
        reelSprite1.setPosition(lWalls.getX(), lWalls.getY());
        reelSprite1.setOrigin(reelSprite1.getWidth()/2,reelSprite1.getHeight()/2);
        reelSprite1.setRotation(180);
        reelSprite1.draw(batch);

then it worked.
