Building a Forest with Functions
We’ll need a lot of trees for our forest. We could build them one at a time, but we’re not going to do that. Instead, let’s add the following JavaScript after all of the avatar body parts:
| | makeTreeAt( 500, 0); |
| | makeTreeAt(-500, 0); |
| | makeTreeAt( 750, -1000); |
| | makeTreeAt(-750, -1000); |
| | |
| | function makeTreeAt(x, z) { |
| | var trunk = new THREE.Mesh( |
| | new THREE.CylinderGeometry(50, 50, 200), |
| | new THREE.MeshBasicMaterial({color: 0xA0522D}) |
| | ); |
| | |
| | var top = new THREE.Mesh( |
| | new THREE.SphereGeometry(150), |
| | new THREE.MeshBasicMaterial({color: 0x228B22}) |
| | ); |
| | top.position.y = 175; |
| | trunk.add(top); |
| | |
| | trunk.position.set(x, -75, z); |
| | scene.add(trunk); |
| | } |
