Whether you’re looking to sway trees in the breeze, animate a character’s greeting, or simply open a door, this tutorial will guide you through the basics of animation in Unreal Engine using timelines and keyframes. Let’s animate the inanimate!

Step 1: Understanding the Basics

First, let’s get a grip on the essentials. Animation in Unreal Engine can be accomplished through various methods, but today we’re focusing on using Timelines and Keyframes—the backbone of basic animation. These tools allow you to control the motion of objects over time in a simple and intuitive way.

Step 2: Setting Up Your Scene

Before we start animating, ensure you have a scene ready. Drop any object into your scene that you’d like to animate. For beginners, I recommend starting with something straightforward, like a rotating fan or a bouncing ball.

  • Create Your Object: In the viewport, drag and drop an object from your content browser. Let’s use a cube for simplicity.
  • Position Your Object: Place your object where you want the animation to occur.

Step 3: Creating a Timeline

Now, let’s create a timeline:

  • Open the Level Blueprint: Access this from the ‘Blueprints’ menu at the top of the screen. The Level Blueprint is where you can control elements within your specific level.
  • Add a Timeline: Right-click in the empty space of your blueprint and search for ‘Add Timeline’. Name it something relevant like ‘CubeRotation’ or ‘BallBounce’.
  • Configure the Timeline: Double-click on the timeline you just created to open its editor. Here you’ll see a graph and tracks where you can add keyframes.

Step 4: Adding Keyframes

  • Create a Float Track: Click ‘Add Float Track’ in your timeline editor. Name it based on what it controls, like ‘Rotation’.
  • Add Keyframes: Shift-click on the graph to create keyframes. Place the first keyframe at time 0.0 seconds with a value of 0 (this represents the starting position). Add a second keyframe at 2.0 seconds with a value of 360 if you’re doing a rotation (this completes a full circle).
  • Adjust the Timeline Settings: Ensure your timeline is set to ‘Loop’ if you want the animation to repeat.

Step 5: Applying the Animation to Your Object

  • Bind the Timeline to Object Properties: Go back to the Level Blueprint and get a reference to your object by dragging it from the World Outliner into the blueprint.
  • Connect the Timeline to the Object: Drag out from the object reference and create a ‘Set Rotation’ node (or any other transformation node based on your animation). Connect your timeline’s update output to this node, and link your float track to the respective input on the transformation node.

Step 6: Test Your Animation

  • Compile and Save: Make sure to compile and save your blueprint.
  • Play Your Level: Hit play in the viewport. Watch as your object comes to life, animating according to the keyframes you set.

Conclusion: Bringing Your World to Life

Congratulations! You’ve just created a simple animation in Unreal Engine 5. The beauty of animation lies in its ability to tell a story and convey emotion, even through the simplest of movements. Experiment with different objects and keyframe values to see how you can enhance your scenes further.

Remember, animation is like music; it requires rhythm and timing to truly resonate. So, tweak your keyframes, adjust your timelines, and let your creative spirits soar with each new movement you craft. Happy animating!
