Is there a way to retrieve the dimensions (width and height) of a Text object from troika-three-text library?
import { Text } from 'troika-three-text'
// Instantiate Text object:
const myText = new Text()
myScene.add(myText)
// Customize properties:
myText.text = 'Hello world!'
myText.fontSize = 0.2
myText.position.z = -2
myText.color = 0x9966FF
// Ensure rendering updates are applied:
myText.sync()
Below are the steps you need to follow:
calculateDimensions() {
const dimensions = new THREE.Vector3()
this.text.geometry.boundingBox.getSize(dimensions)
return { width: dimensions.x, height: dimensions.y }
}
In order to ensure everything runs smoothly, it's important to retrieve the values after they have been calculated. One way to achieve this is by listening for the syncfinish event:
myText.addEventListener("syncfinish", () => {
const height = text.geometry.boundingBox.max.y - text.geometry.boundingBox.min.y;
// ...
});
