// ====================================================================================================================
// User controlled (not Mind controlled) 3D model World with various features:
// - User controlled UP/LEFT/RIGHT arrows move model
// - "First Person View" - Camera rotates with direction you are facing
// Best effect is with "Move with" camera
// - Can have one or multiple skeletons chasing you
// Smooth movement
// UP moves forward in whatever angle you are at
// LEFT/RIGHT rotate by small angle
// Uses x,y,z rather than grid of squares
// Has collision detection for skeleton moves
// Things to do:
// - Initialise skeletons so they are not already colliding
// - Collision detection for agent moves

// You should be able to change things in this box without being a JavaScript programmer.
// Go ahead and change some of these. What's the worst that could happen?

//--- lookat and follow -----------------------------------------------------------------
// camera on "Move With" should move up/down in y axis as we re-scale objects
// to place the follow camera just above the agent, something like:
const followY= scalePlayer * 4; // going high up (or forward/back) means we get it out of agent's hair
// to point the camera at skeleton's face, something like:
const lookatY = scaleDoll * 40;
//const CAMERASHIFT = 0 ;// put camera exactly inside agent's head
//const CAMERASHIFT = SCALE_HERO * 2 ;// shift camera ahead of agent along line of sight
const cameraShift = -scalePlayer * 2; // shift camera behind agent, looking past agent along line of sight
//--- change ABWorld defaults: -------------------------------

ABHandler.GROUNDZERO = true; // "ground" exists at altitude zero
// --- Rotations -----------------------
// rotate by some amount of radians from the normal position
// default is 0 which has the model facing DOWN (towards increasing z value) as far as the initial camera sees
const rotateConstant = Math.PI / 20; // rotate amount in radians (PI = 180 degrees)
