LookAt question (coding)

[Jorik_Rosa]

Hi guys!
Task: The button needs to look always to the camera

I really sucked in code )) but one of my friends give me this one

const Scene = require(‘Scene’);
const R = require(‘Reactive’);
const Time = require(‘Time’);
const Patches = require(‘Patches’);
const DeviceMotion = require(‘DeviceMotion’);

const TouchGestures = require(‘TouchGestures’);

// Use export keyword to make a symbol available in scripting debug console
export const Diagnostics = require(‘Diagnostics’);

// Enables async/await in JS [part 1]
(async function() {
const [bossNull, boss, camera] = await Promise.all([
Scene.root.findFirst(‘bossNull’),
Scene.root.findFirst(‘plane0’),
Scene.root.findFirst(‘Camera’)
]);

let angle = getAngleBetweenVertices();

// Here if i moving around object its moving to the camera.
boss.transform.rotationY = degrees_to_radians(angle.z);

// if i add another axes its ruined and object work not well
// boss.transform.rotationX = degrees_to_radians(angle.y);

function normalizeAngle(angle){
    if (R.gt(angle, R.val(360))) {
        return angle.sub(R.val(360));
    }
    if (R.lt(angle, 0)) {
        return angle.sum(R.val(360));
    } else return angle;
}

function getAngleBetweenPoints(cx, cy, ex, ey){
    var dy = R.sub(ey,cy);
    var dx = R.sub(ex,cx);
    var theta = R.atan2(dy, dx);
    return R.mul(theta, R.val(180/Math.PI))
}

function getAngleBetweenVertices(){
    return R.point(
        normalizeAngle(getAngleBetweenPoints(bossNull.worldTransform.position.z, bossNull.worldTransform.position.x, camera.worldTransform.position.z, camera.worldTransform.position.x)),
        normalizeAngle(getAngleBetweenPoints(bossNull.worldTransform.position.z, bossNull.worldTransform.position.y, camera.worldTransform.position.z, camera.worldTransform.position.y)),
        normalizeAngle(getAngleBetweenPoints(bossNull.worldTransform.position.x, bossNull.worldTransform.position.y, camera.worldTransform.position.x, camera.worldTransform.position.y))
        )
}

function degrees_to_radians(degrees) {
    var pi = Math.PI;
    return R.mul(degrees, R.val(pi/180));
}

})();

How to solve this problem?

I think the easiest way to get billboarding is to use a particle system. For tap events, you’ll need to add a sphere or something else as the target.

Otherwise, maybe this thread will help you.

SceneObject.transform.rotation and tracked planes - how do they interact? (scripting and/or patches)

Hey @Tomas_Pietravallo, our project is finished and the sprite I got to look at the user got replaced by a 3D-object that needs no orienting Still, I wanted to leave this look-at-thing in a better state than it was, and so I got rid of the patches. The code looks different here, but just the necessary bits are this: const S = require('Scene'); const R = require('Reactive'); const D = require('Diagnostics'); const DeviceMotion = require('DeviceMotion'); // The planeTracker0 in my sce…

Thank you as always! try to figure it out stay tuned
