Paddle

When replacing sprites take a look at the original size of the texture and the pixels per unit setting and if the sprites are sliced or not.

The original paddle sprite is sliced and uses 200 pixels per unit. The size and draw mode on the sprite renderer component is also important.

Draw mode: Sliced

Size: Width: 1.3 Height: 0.325

Once you have your sprite ready you can either replace it on the prefab or replace the original sprite using the same name.

To replace the original sprite, delete the existing one under Assets / QuietCraft / Breakout / Textures / Paddle and then drag your custom paddle texture in the same location. Use the same file name and format. Now make sure the Paddle prefab and your sprite have the settings mentioned above set correctly.

Manual Replacement

Find the Paddle prefab under Assets / QuietCraft / Breakout / Prefabs / Paddle and double click to open it.

Change the sprite on the sprite renderer component of the paddle to your custom paddle sprite.
