In this first part of my DOTween tutorial series, I walk you through the full beginner setup so you can start creating smooth animations directly inside Unity. I show you where to find DOTween on the Unity Asset Store (it’s free), how to import it into your project, and what to do when the DOTween setup window pops up. That setup wizard is important because it configures the project settings behind the scenes so DOTween runs correctly and efficiently. After setup, I keep things simple with a cube in the scene and write our first animation script. I start by adding DOTween’s namespace, then inside Start() I use DOMoveX to move the object along the X-axis to a target position over a set duration. You’ll see the cube smoothly move five units to the right in two seconds. Then I upgrade it by chaining a second motion using OnComplete, so right after the first move finishes, the cube immediately moves upward. The main takeaway is how fast you can get polished movement, and how easy it is to build sequential animations by chaining tweens.
