Getting Started - Chapter 8 - Follow That Character
Follow That Character
Without using parenting we can also track the characters movements with a FollowCamera.
We give a FollowCamera a start position and a target to follow and a goal position from which to view the target.
We create the FollowCamera with a name, start position and the optional scene parameter.
const camera = new BABYLON.FollowCamera("FollowCam", new BABYLON.Vector3(-6, 0, 0), scene);
We then set the goal: height above the the center of the target;
camera.heightOffset = 8;
radial distance from target plus height offset;
camera.radius = 1;
rotation, in radians, center of target in x y plane;
camera.rotationOffset = 0;
acceleration in moving from current to goal position;
camera.cameraAcceleration = 0.005
speed at which acceleration is halted
camera.maxCameraSpeed = 10
Of course we also attach the camera to the canvas
Finally we set the target
camera.lockedTarget = targetMesh;
Having created a 3D world, albeit just a small village, it would be good to see it in all its 3D glory. All you need is a 3D viewer whether a simple one such as the Google Carboard or a high tech one and the appropriate camera from Babylon.js.
