How to Remove Smoothing from DoMove in Unity using DOTween

If you're working with Unity's DOTween library to create smooth movements in your game, you might encounter a common issue: your objects slow down as they reach their destination when using the DoMove function. This can disrupt the flow of your game and create a frustrating user experience. But fear not! In this post, we'll explore a straightforward solution to this issue by adjusting the easing settings in DOTween.

Understanding the Problem

When you use the DoMove function, DOTween applies a default easing function that causes your object to decelerate as it approaches its target position. While this might look visually appealing in some contexts, it doesn't always fit well with every game or effect. If you prefer a more consistent speed throughout the object's movement, you'll want to remove that smoothing effect.

Solution: Using DOTween's Ease Settings

The good news is that DOTween provides us with the tools we need to change the easing type easily. Here's how to do it to achieve a more linear movement:

Step 1: Modify the DoMove Function

To change the easing type for a specific movement, you can modify your DoMove call by appending the SetEase method. Use the Ease.Linear option to remove the smoothing effect completely. Here’s an example of how to implement this:

In this code:

transform refers to the object you want to move.

position is the target destination for your object.

overTime defines how long the movement will take.

By using Ease.Linear, the object will maintain a constant speed from start to finish, eliminating any slowdown at the end.

Step 2: Set a Default Easing Type

If you find that you want all your movements to have this linear effect by default, you can adjust the default easing type in DOTween. This way, you won't have to specify it every time you call the DoMove function. Set the default ease type like this:

With this line of code, all future tweens will use a linear easing by default unless specified otherwise. This can save you time and ensure consistency across your game.

Conclusion

By adjusting the easing settings in DOTween to either apply Ease.Linear on a per-tween basis or set it as the default, you can effectively remove the smoothing effect that occurs at the end of movements using DoMove. This will result in a more predictable and smooth movement for your game objects, enhancing the overall experience for your players.

Now go ahead and implement these changes in your Unity projects. Happy coding!
