Question Question on how to improve my little physic ball game

I'm creating a small game for my AR application, where I control a ball by tilting the plane I'm holding in my hand.

I've added a Rigidbody component to the sphere, and while it works, controlling the ball is proving to be too difficult. Is there a way I can improve its responsiveness? Do I need to create a custom script for this?

I've attempted to adjust the Rigidbody settings, but unfortunately, I haven't had much success.

Could anyone help me out?

 

Rigidbody mass and angularDrag would be the relevant physics settings. Also you could increase gravity to just make it fall harder downwards. The collider/rigidbody surface material, and your plane collider material, affect bounciness and friction, if you want those.

 

You may be able to improve responsiveness by increasing the physics frame rate.

Project Settings/Time/Fixed Timestep

Change it to 0.01666 for 60 frames per second.

 

First of all thank you for your help, and I want to ask you: what type of surface material can affect friction?

Thanks I will try it

 

They are called Physic Materials, if you look at any 3D collider you'll see this field. It's not the same as a rendering material although the field name is the same. You can create new Physic Materials yourself from the Create menu.

 

Thank you , I will try it out

 

I'm trying to change the parameters that you told me about here, but it doesn't seem to influence the ball at all. For this reason, I want to ask you if the size of the ball could influence the rigidbody, because the ball's size is set to 0.006 and the collider size is set to 0.5.

 

I think your scales are too small which can cause physics issues. Physics is tuned to work with reasonable scales and it's better if mass and scale are closer to 1. If your ball represents a real life marble, then maybe think of units like 1 = 1 cm, and scale all your objects with this basic unit.

 

If you're using AR Foundation then the tracking can be a little iffy, especially if you're looking down at the ground and there's not many trackable features down there. If you just need a virtual ball to roll around on the screen then you could look into bypassing AR Foundation and using the gyroscope for tracking and enable the camera yourself.

 

Oh wait... I just realized that you may be using image tracking to control the plane that the ball rolls around upon. I once had a play around with image tracking and I found it to be very unreliable. So you may be asking a little too much to be able to control the ball reliably..

You may be able to add a rigidbody to a plane that tracks the image marker that tracks your hand and this should give smoother results but then you'll probably have lots of latency.
