Experiencing an "Undefined Object" error while attempting to rotate an object using three.js. Here is a snippet of the code in question:
var object;
function render() {
renderer.render(scene, camera);
}
function animate() {
object.rotation.x += 0.1;
render();
requestAnimationFrame(animate);
controls.update();
}
Let's simplify this by focusing on the problem code only:
var object; // undefined
object.rotation.x += 0.1; // attempting to access a key in an undefined object
While declaring object in the global scope is permissible, it's crucial to note that you're simply declaring it without assigning a value. This results in an attempt to access a key within an object that is undefined.
var object = {};
object.rotation.x += 0.1; // object.rotation is undefined
This approach is still insufficient. The variable object lacks a key called rotation, leading to it being undefined. Consequently, you're trying to access a key that does not exist. While I'm uncertain about your specific requirement, in this particular case, assigning object as an object with all the necessary keys manually can resolve the undefined issue you're facing.
var object = {
rotation: {
x: 0
}
};
object.rotation.x += 0.1;
