Additionally, this technique offers the ability to use blend trees and state machines to enhance the complexity of the animations.
Pros
One major benefit of using Play Animation From Script is the increased level of control it offers to game developers. Developers can implement custom logic using code, allowing for deeper customization of animations beyond basic parameters. Furthermore, using animation via scripting is far more efficient than traditional animation since developers can re-use animations by scripting them to react differently to different input parameters.
Cons
On the downside, Play Animation From Script requires extra resources to be able to implement correctly. Programmers must understand how to work with animations as well as the scripting system itself. Additionally, in comparison to traditional animation methods such as keyframe animations, the process of debugging may take much longer when implementing script-animated games.
Traditional Animation Techniques
Animations created with traditional animation techniques are made up of a sequence of frames, similar to a flipbook. Each frame is hand-drawn, or a 3D model is created, and they are compiled together to create the final animation. This method can be effective for creating one-time animations for cut scenes and boss battles.
Pros
Traditional animation techniques offer a more natural workflow because developers work with tangible tools to create finalized animations. An animator can use pencils and paper to sketch and bring their ideas to life physically. This way allows animators to iterate on specific animation elements quickly.
Cons
One potential downside is that traditional animation methods can be time-consuming. The lengthy and complex process entails creating each frame manually, which often requires several iterations to achieve the desirable effect. Additionally, editing and tweaking animations using these methods require re-drawing every part of it, which can be incredibly frustrating if changes are frequent or minute.
Comparative Table
| Criteria | Unity Play Animation From Script | Traditional Animation Techniques |
|---|---|---|
| Level of Control | High | Low |
| Reusability | High | Low |
| Workflow | Complex | Straightforward |
| Resource Requirements | High | Low |
Conclusion
Both Unity Play Animation From Script and traditional animation techniques have their pros and cons. Play Animation From Script is more efficient in terms of time and resources. However, it stands as the better option if the level of complexity in games necessitates greater control. Conversely, traditional animation methods are often simpler and offer a more natural work-flow process.
Ultimately, the choice of animation technique comes down to game developers' preference based on the requirements of the project at hand. In well-designed games, these techniques come together to create immersive experiences that players will enjoy.

Gone are the days when animators used to create animations by hand, which was a time-consuming and exhausting activity. The emergence of Unity has simplified the animation process and made it possible to animate objects using scripts. Animating objects from a script is a powerful way to program your game much more efficiently and control the sequence of animation events.
Firstly, you need to have a 3D model in your project and have an animator component attached to it. The animator component allows you to create animations that can be triggered based on an event or a condition. Once you have the animator component attached to your model, you can create animation clips in the animation window, which can then be edited and refined.
One of the added benefits of playing animations in Unity from a script is that you can have full control over the animation's playback speed, direction, and start and stop times. You can add triggers to your animations at selected points in the timeline to perform specific actions, such as moving an object, playing audio, or triggering other animations.
If you want to play an animation from a script, you will need to follow a few simple steps. Firstly, ensure that you have assigned the correct animation controller to the animator component attached to your model. This controller contains the animation clips you have created in the animation window.
Next, you need to access the animator component from your script using the GetComponent() function. This function retrieves the animator component for the specified object. Once you have obtained the animator component, you can call its Play() function to play the animation. You can also specify the name of the animation clip you want to play as a parameter inside the Play() function.
The key when playing an animation from a script is to ensure that the animation clip name and the trigger name are identical, otherwise, the animation will not be triggered. You can use the SetTrigger() function inside your script to set the trigger. For example, if you have an animation clip named jump, you can set the trigger in your script using the SetTrigger(jump) function.
If you want to control the speed of the animation playback, you can use the animator component's Speed variable. This variable controls the speed at which the animation is played, with a default value of 1. You can change the value of this variable inside your script to make the animation play faster or slower.
Another useful feature of Unity's animator system is the ability to blend animations smoothly. When blending animations, the animator component calculates the weight of each animation and blends them together. You can use the animator component's SetFloat() function to adjust the blend value between the animations, and smoothly transition from one animation to another.
If you need to check whether an animation is currently playing or not, you can use the IsPlaying() function of the animator component. This function takes an integer parameter that corresponds to the layer index of the animation in the animator controller.
Finally, one thing to remember when playing animations from scripts is to initialize all variables and components before running the game. This is important to avoid null errors when calling objects that have not been initialized. In addition, use debugging tools such as breakpoints to ensure that your scripts are correctly executing the desired actions and implementing the logic you have defined.
In conclusion, playing animations from scripts can be a powerful tool for controlling the sequence of animation events and programming your game efficiently. With Unity's animator system, you can create and manipulate animations easily and make your games more engaging and interactive than ever before. Hopefully, this guide has given you a comprehensive understanding of how to play animations from a script in Unity and has been useful in your game development endeavors.
