hello, sorry I'm french I used a translator
I started on babylon js, I would change the file follow camera because I lack a setting.
I would like to keep close enough for my camera model with a radius asser near, and to be able to see my character:
My current camera follow :
var camera = new BABYLON.FollowCamera("mainCamera", new BABYLON.Vector3(0, 0, 10), scene);
camera.radius = 4;
camera.heightOffset = 3;
camera.rotationOffset = 0; // the viewing angle
camera.cameraAcceleration = 0.03; // how fast to move
camera.maxCameraSpeed = 10; // speed limit
camera.position = new BABYLON.Vector3(0, 50, 100);
Example of the scene :
http://tokadoki.com/HTML5/plateform/index.html (move z,q,s,d)
I would like to mount the camera on the y axis in gardantles all properties of the camera follow.
but I think for that you need to touch the babylon js code by adding a parameter or modifying
somebody would have the solution if it please you thank you :
code babylon.js :
var BABYLON;
(function (BABYLON) {
var FollowCamera = (function (_super) {
__extends(FollowCamera, _super);
function FollowCamera(name, position, scene) {
_super.call(this, name, position, scene);
this.radius = 12;
this.rotationOffset = 0;
this.heightOffset = 4;
this.cameraAcceleration = 0.05;
this.maxCameraSpeed = 20;
}
FollowCamera.prototype.getRadians = function (degrees) {
return degrees * Math.PI / 180;
};
FollowCamera.prototype.follow = function (cameraTarget) {
if (!cameraTarget)
return;
var yRotation;
if (cameraTarget.rotationQuaternion) {
var rotMatrix = new BABYLON.Matrix();
cameraTarget.rotationQuaternion.toRotationMatrix(rotMatrix);
yRotation = Math.atan2(rotMatrix.m[8], rotMatrix.m[10]);
}
else {
yRotation = cameraTarget.rotation.y;
}
var radians = this.getRadians(this.rotationOffset) + yRotation;
var targetX = cameraTarget.position.x + Math.sin(radians) * this.radius;
var targetZ = cameraTarget.position.z + Math.cos(radians) * this.radius;
var dx = targetX - this.position.x;
var dy = (cameraTarget.position.y + this.heightOffset) - this.position.y;
var dz = (targetZ) - this.position.z;
var vx = dx * this.cameraAcceleration * 2; //this is set to .05
var vy = dy * this.cameraAcceleration;
var vz = dz * this.cameraAcceleration * 2;
if (vx > this.maxCameraSpeed || vx < -this.maxCameraSpeed) {
vx = vx < 1 ? -this.maxCameraSpeed : this.maxCameraSpeed;
}
if (vy > this.maxCameraSpeed || vy < -this.maxCameraSpeed) {
vy = vy < 1 ? -this.maxCameraSpeed : this.maxCameraSpeed;
}
if (vz > this.maxCameraSpeed || vz < -this.maxCameraSpeed) {
vz = vz < 1 ? -this.maxCameraSpeed : this.maxCameraSpeed;
}
this.position = new BABYLON.Vector3(this.position.x + vx, this.position.y + vy, this.position.z + vz);
this.setTarget(cameraTarget.position);
};
FollowCamera.prototype._update = function () {
_super.prototype._update.call(this);
this.follow(this.target);
};
return FollowCamera;
})(BABYLON.TargetCamera);
BABYLON.FollowCamera = FollowCamera;
})(BABYLON || (BABYLON = {}));
//# sourceMappingURL=babylon.followCamera.js.map
var __extends = this.__extends || function (d, b) {
for (var p in b) if (b.hasOwnProperty(p)) d[p] = b[p];
function __() { this.constructor = d; }
__.prototype = b.prototype;
d.prototype = new __();
};
