Im pretty new, hope someone can help with this trivial question :)
The array is globaly defined var textMeshes = ; and a function to generate the text at a certain position The function works but i cannot access the array by index, I get a console error that textMeshes is not defined. But if i log textMeshes console.log(textMeshes) as hole array i see the array is filled. console.log(textMeshes[0]) results in undefined. I guess the issue is because fontLoader loads asyncron but please correct me if im wrong =). I really appreciate your help!

function addTextToScene (posX, posY, posZ, i){

                var fontLoader = new THREE.FontLoader();

                fontLoader.load( 'fonts/droid/droid_sans_regular.typeface.json', function ( font ) {



                    var textGeometry = new THREE.TextGeometry( '#' + i, {

                        font: font,

                        size: 16,

                        height: 5,

                        curveSegments: 12,

                        bevelEnabled: true,

                        bevelThickness: 1,

                        bevelSize: 0,

                        bevelSegments: 5

                    } );





                 textMesh = new THREE.Mesh( textGeometry, textMaterial );



                 var textMaterial = new THREE.MeshPhongMaterial({ color: 0xff0000, specular: 0xffffff, shininess: 100, emissive: 0xffffff});



                 textMesh.position.x = posX;

                 textMesh.position.y = posY+50;

                 textMesh.position.z = posZ-50;



                 textMeshes.push( textMesh );

                 scene.add( textMesh );





                } );









            }

You are correct: the FontLoader.load() callback is asynchronous, so textMeshes going to be empty until after its content is loaded. Only then will this line take place:

textMeshes.push( textMesh );

before that, textMeshes[0] is going to be undefined because texMeshes has nothing inside it; it has a length of 0.

This is not much of a Three.js question, but more of an AJAX question. You should read this discussion to get more acquainted with the topic: How do I return the response from an asynchronous call?
