As I delved into a WebGL project, leveraging the powerful Sim.js and Three.js libraries, an unexpected obstacle emerged:
At a certain point, within the code, the constructor for THREE.Ray is utilized in this manner:
var ray = new THREE.Ray( this.camera.position, vector.subSelf( this.camera.position ).normalize() );
Here, 'vector' represents a Vector3,
Yet, an error is provoked, stating:
TypeError Object[object object] has no method subSelf.
Upon consulting the documentation for the version of Three.js being utilized, it appears that a method resembling this is
.sub( v ) Vector3
After making this alteration, a new issue arises when executing:
var intersects = ray.intersectScene( this.scene );
An error is thrown once more, as the 'ray' object lacks an 'intersectsPlane' method
