It's a placeholder function, does nothing yet.

I'm understood, thank you.

Hi cameni!

Code: [Select]
this.geom = this.get_geomob(0);
var bone = this.geom.get_joint("bone_1");
var angle = Math.random()*3.14;
this.geom.rotate_joint_orig(bone, angle, {x:0,y:1,z:0});

var boneAngle = // How get rotate joint "bone"?

Грустно всё это  :(
Возвращаемый методом результат статичен, не учитываются внесённые изменения позиции и углов поворота кости.

Hi cameni!

Code: [Select]
var mtm = this.geom.get_bone_model_tm(this.point_gun_l_fire);
var firePos = mtm.pos;
var fireDir = // how to convert mtm.rot -> float3 dir - model-space direction of firing;
this.fire(firePos, fireDir, 800, 0.23, {x:1,y:.8});

rot is a quaternion, and if you want the direction of +y axis (the forward axis in model space), then you'd multiply rot * float3(0,1,0), which can be simplified in JS to:

Code: [Select]
fireDir = {
x: 2 * (rot.x*rot.y - rot.w*rot.z),
y: 1 - 2*(rot.x*rot.x + rot.z*rot.z),
z: 2 * (rot.y*rot.z + rot.w*rot.x)}

Теперь я понял причину не удачи, ход моей мысли был правильный.
Но я запрашивал параметр radius, мне возвращался NULL. Мне стоило опросить другие параметры).
Но такое положение завело меня в тупик, мне нужно управлять параметром radius, что бы решить эту задачу.



PS
I have an idea! How to solve.

I saw a problem similar to this when looking at some stuff about Bullet boat physics. It had a suggestion about invisible attachments that had specific weight and gravity parameters to keep an object at a predetermined angle..... (not sure if that helps)

Like today operates a ground vehicle simulations. That is, the wheel itself should not be a mesh.

Моя идея оказалась верной, но принесла с собой другую проблему.
Я понимаю что можно создать дубли сеток колёс, и в зависимости от состояния шасси скрывать одни и показывать другие.
Но по мне такая реализация выглядит как костыли(medical term), и мне совсем не нравятся подобные реализации.
