3D Game Programming

3.1 Getting Started

Let’s open the ICE Code Editor^1 again and create a new project named My

Avatar (check Start a New Project, on page 17, if you don’t remember how).

Be sure to leave the template set to 3D starter project. With that, we’re ready to

start programming on the line following START CODING ON THE NEXT LINE.

3.2 Making a Whole from Parts

From Chapter 1, Project: Creating Simple Shapes, on page 1, we already know

how to make basic shapes. Let’s start building our player avatar by making

a sphere for the body.

varcover =newTHREE.MeshNormalMaterial();

varbody =newTHREE.SphereGeometry(100);

varavatar =newTHREE.Mesh(body, cover);

scene.add(avatar);

We already know what happens when we type that in—we get a ball in the

center of the scene.

Let’s add a hand next to the body. Add the following lines below the code that

you already entered to create the body.

varhand =newTHREE.SphereGeometry(50);

varright_hand =newTHREE.Mesh(hand, cover);

right_hand.position.set(-150, 0, 0);

scene.add(right_hand);
