 ## Adding powerups ## Adding powerups
  
-We will add two objects called **"PowerupHealth"**, and **"PowerupShield"**. Select the **"powerup\_health.png"** image from the assets folder for the health object. Repeat the same process for shield object by choosing the **"powerup\_shield.png"** image. In the end, you should see:+We will add two objects called **"PowerupHealth"** and **"PowerupShield."** Select the **"powerup\_health.png"** image from the assets folder for the health object.

 ## Animating the player ## Animating the player
  
-We are using animations to change the player's sprite when the player collides with **PowerupShield**. Open the player's properties panel and enter **"PlayerIdle"** in Animation#0.

 ## Testing out ## Testing out
  
-Before testing out the meteors, we should **put some meteor objects on the scene**. **Drag and drop** some meteor items on the scene.+Before testing powerups, we should change the scale of powerup objects just like in the previous cases. Select **Powerups object group** and set scale factor to **1.5**:

-Run the game. Now you can see the meteors on the scene. If you hit some meteors, you will get damage. +Then, open the scene view and drag and drop the powerup objects to the scene. We are ready to run the game. Now you can see the powerups on the scene. If you collect **health's powerup**, **the player's health will be increased by 30**. If you collect the **shield's powerup**, the **player's sprite will be changed**, and you will not get damaged for 5 seconds.
