v4.1.1 Win64
Hey there! i’m kinda new to gamedev and i’m trying to make a 3d dice roller for my crpg. I programmed a rolling system using a rigidbody, and made a little box for my die to roll in (4 collision shapes) but my problem is that my die rolls and bounces far too much! how do i make it less bouncy/rolly?
If you have a gravity property for that object, I guess you should increase that.
If you don’t, then I would recommend adding it.
It does depend on the rolling system… so unless you share some code, all we can do is guess.
I tried increasing the mass of my rigidbody, it did not seem to work (or do anything, for the record)!
if i decrease the force of my dice throw, which is controlled by the variable “roll_strength”, the dice will still go to the wall and bounce a bunch, only much slower, if the gravity (the gravity slider on the Rigidbody) is increased, the dice wobbles indefinitely
here’s an example of what the die rolling looks like
extends RigidBody3D
var clicked = false
var overDie = false
var body = RigidBody3D
var start_pos
var roll_strength = 5
func _ready() -> void:
connect("mouse_entered", whatever)
connect("mouse_exited", whatever2)
func whatever2():
overDie = false
func whatever():
overDie = true
func _input(event):
if event is InputEventMouseButton:
if event.button_index == MOUSE_BUTTON_LEFT and event.pressed:
clicked = true
if event.button_index == MOUSE_BUTTON_LEFT and event.pressed == false:
clicked = false
var mouse_pos = get_viewport().get_mouse_position()
if overDie:
if clicked:
print("rolled die")
_roll()
func _roll():
sleeping = false
freeze = false
linear_velocity = Vector3.ZERO
angular_velocity = Vector3.ZERO
transform.basis = Basis(Vector3.RIGHT, randf_range(0, 2 * PI)) * transform.basis
transform.basis = Basis(Vector3.UP, randf_range(0, 2 * PI)) * transform.basis
transform.basis = Basis(Vector3.FORWARD, randf_range(0, 2 * PI)) * transform.basis
var throw_vector = Vector3(randf_range(-1, 1), 0, randf_range(-1, 1)).normalized()
angular_velocity = throw_vector * roll_strength /2
apply_central_impulse(throw_vector * roll_strength)
try add physics material to dice and floor
Didn’t seem to work, the dice still rolls into infinity
Did a short google search, and it seems you are following this tutorial:
It is important to mention this in your question…
It does help us a lot.
Just by looking at this I can tell that my first answer is not a good one.
I have to look more into this.
The physics material has a “bounce” property, playing with that may give you an answer.
I do not have the time to look more into this atm, will be back with an answer in a few days if that is not too late.
I did a quick tests using the same code you have provided.
I could not reproduce the error from your video.
There is nothing wrong with this code:
sleeping = false
freeze = false
linear_velocity = Vector3.ZERO
angular_velocity = Vector3.ZERO
transform.basis = Basis(Vector3.RIGHT, randf_range(0, 2 * PI)) * transform.basis
transform.basis = Basis(Vector3.UP, randf_range(0, 2 * PI)) * transform.basis
transform.basis = Basis(Vector3.FORWARD, randf_range(0, 2 * PI)) * transform.basis
var throw_vector = Vector3(randf_range(-1, 1), 0, randf_range(-1, 1)).normalized()
angular_velocity = throw_vector * roll_strength /2
apply_central_impulse(throw_vector * roll_strength)
Try commenting this code:
func _input(event):
if event is InputEventMouseButton:
if event.button_index == MOUSE_BUTTON_LEFT and event.pressed:
clicked = true
if event.button_index == MOUSE_BUTTON_LEFT and event.pressed == false:
clicked = false
var mouse_pos = get_viewport().get_mouse_position()
if overDie:
if clicked:
print("rolled die")
_roll()
Then add a button with an event that rolls the die. See if the error still happens then.
in relation to what Moreus said
i have toyed around with the PhysicsMaterial of the dice, and nothing seems to work, could it be the shape of the die ?
what shape is it?, and if it this help
as it might help you and us understand what is going on with the collisions
Also, if you were wondering what i WANT the dice roller to be like, i’m basically trying to make a copy of the Owlbear Rodeo dice roller:
Here’s the die with no mesh, and with Visible Collision shapes
https://youtu.be/HjuFJ1rzlVw?si=wehWZnZA8Q26X2qX
The shape is a Rhombic d12, also known as a Rhombic Dodecahedron
HEY ALL! thought i’d give an update, i found out how to stop the dice from rolling/bouncing: using JOLT physics !
