Aside from the Move and Rotate options on the Basic Animation of our Interactivity feature, you can also scale your objects!

If you're still looking for ways to do so, well, it's fairly simple and easy! However, before, we jump right into the steps, we'll tell you a brief about the creation.

For this tutorial, we have two objects—a gorilla and an elephant—on our creation. The logic is simple; when we tap or click on the gorilla, it will shrink and go smaller. Meanwhile, when we tap or click on the elephant, it will grow bigger.

Are you ready? Let's follow the steps below:

1. Start by adding the Interactivity

First up, what we're gonna do is just click on the gorilla.

Then, choose Add Interactivity, and pick Scale.

Here, you can choose how you want to scale your objects:

  • Out: When you click on an object, your object will grow bigger.
  • In: When you click on an object, your object will go smaller.
  • Custom: Customize your scale direction by inputting the number.

Since we already know that we want to make the gorilla smaller, let's choose In!

Meanwhile, for the elephant, you can just repeat the steps above. However, for the elephant, we'll choose Out to make it grow bigger.

2. Set up your Interactivity!

The first thing you will do is to set your target object.

So when you click on an object, you can set it as a trigger and make the target object scale.

However, in this case, we're gonna leave them as they are. For the gorilla, the target object will still be the gorilla, and that also happens for the elephant.

Then, you can also insert the size of your scaling. The bigger the number, the more the scale amount of your object—and vice versa.

Now, don't forget to set the advanced settings! Here are some details you need to know:

  1. Start Time: Determine the time your object starts to move after you click or tap on it.
  2. Duration: Determine how long your object will move.
  3. Easing: Specify the motion of your object, so at some points, it may accelerate or decelerate.

For Easing, you can choose among these 4 options:

  1. Linear: The object's motion will be static.
  2. In Sine: The object will rotate faster at the end of the motion.
  3. Out Sine: The object will rotate faster at the beginning of the motion.
  4. In Out Sine: The object will rotate slower in the beginning, fasten up in the middle, and get slower again at the end.

And that's it! If you're done setting it up, just click Apply. Before your post, it's better to give it a check and preview it one last time.

Ready to give it a whirl? Looking forward to your awesome creations and stay tuned for the upcoming Interactivity tutorials!
