voxel-trajectory

Calculate trajectories in voxel.js.

example

Create a trajectory to throw an item based on the direction the camera is facing:

var trajectory = require('voxel-trajectory');
 
// x,y of voxel.js camera
var camera = game.cameraRotation();
 
// rotate the axis -90 degs to throw forward
camera[0] -= Math.PI / 2;
 
// create an item with a velocity of 2 towards trajectory
var item = {
  velocity: trajectory(2, camera),
  mesh: /* ... */,
  size: game.cubeSize,
  resting: false
};
game.addItem(item);

The trajectory can be from anywhere, such as a meteor:

var meteor = {
  velocity: trajectory({
    // pretty fast
    velocity: 5,
    // 45 degrees
    rotation: [Math.PI / 180 * 45, Math.PI / 180 * 45, 0],
    // from the sky
    origin:   [1000, 5000, 1000]
  })
};
