示例1: moveAlong
moveAlong(elapsedTime: number, speed: number): Vec3 {
// If there is no further waypoint, we've arrived at the end and we
// always return the current position.
if (this.done) {
return vec3.clone(this.currentPosition);
}
// The vector from the current position to the next waypoint.
var vector = vec3.subtract(vec3.create(), this.waypoints[0], this.currentPosition)
, vectorLength = vec3.length(vector)
, distanceMoved = speed * elapsedTime;
if (vectorLength < distanceMoved) {
// The remaining distance in the current segment is less than what
// we moved, jump to the next waypoint and move along the next path
// segment from there.
vec3.copy(this.currentPosition, this.waypoints.shift());
this.currentHeading = normalizeHeading(Math.atan2(vector[1], vector[0]));
return this.moveAlong(elapsedTime - vectorLength / speed, speed);
}
// We have not yet reached the next waypoint. Move along the vector
// towards it and update the heading.
