Adjusting Animation Speeds in Theatre.js

Sounds like you’re having a great time with Three.js and Theatre.js! 🎉 Adjusting animation speed can definitely help make your scene feel more cohesive. Here’s a simple way to tweak your animation speeds.

If you’re looking to change the speed of your animations, you might want to look at using a property called `duration` on your animations in Theatre.js. This property determines how long the animation will play. So, if an animation feels too fast, you can increase the duration, and if it’s too slow, you can decrease it.

const myAnimation = scene.animate({
    // your animation parameters
    duration: 2000 // increases the duration to 2 seconds
});
    

In some cases, you can also adjust the timing directly in the keyframes. Tweaking the timing of individual keyframes can give you more control if you’re working with complex animations. But just a heads up, that might get a bit tricky if you’re just starting out!

Global Speed vs Individual Adjustments

About managing timing, a lot of people prefer adjusting each animation separately, especially to create a unique feel for each object. That way, if you want one object to move slower than another, you can just set its duration accordingly.

Some folks do mention using time scaling. In Three.js, you can set a “time scale” factor that multiplies the overall animation time, but it might be easier to stick with adjusting durations for now while you’re getting the hang of things!

Example Snippet

// Example of changing duration in Theatre.js
theatre.on('change', (next) => {
    next.animations.forEach(animation => {
        animation.duration *= 1.5; // Slows down all animations by 50%
    });
});
    

Just experiment with the properties, and you’ll start to figure out what feels right for your scene! Hope this helps, and keep having fun with it! 😄
