Is trigger a unity?
A trigger is related to colliders from the physics engine. Unity documentation states that: “An alternative way of using Colliders is to mark them as a Trigger, just check the IsTrigger property checkbox in the Inspector.
What does isKinematic mean in unity?
Description. Controls whether physics affects the rigidbody. If isKinematic is enabled, Forces, collisions or joints will not affect the rigidbody anymore. The rigidbody will be under full control of animation or script control by changing transform.
Can you smoke in 0 gravity?
A spaceship orbiting earth is moving fast enough to break gravity and the vacuum of space has no density. In this case the smoke may expand in all directions, or the direction of force applied by an explosion and continue moving at the same direction and velocity of the object that created the ‘burn’ process.
What is Rigidbody 2D?
The Rigidbody2D class essentially provides the same functionality in 2D that the Rigidbody class provides in 3D. Adding a Rigidbody2D component to a sprite puts it under the control of the physics engine. By itself, this means that the sprite will be affected by gravity and can be controlled from scripts using forces.
Does OnTriggerEnter need Rigidbody?
A Rigidbody is necessary for at least one of the objects if you want to receive the OnTriggerEnter/OnTriggerStay/OnTriggerExit messages, even if the collider is a trigger. The trigger methods ( OnTriggerEnter/OnTriggerStay/OnTriggerExit ) receive a Collider argument, not a Collision , this is a really common issue.
Why does gravity not pull smoke down?
Smoke particles are only slightly denser than air molecules, and often have a flat shape, so the pull of gravity isn’t strong when acting on the small smoke particles, which resist being pulled down through the air.
Is there oxygen in zero gravity?
In microgravity, there’s no updraft and oxygen is drawn into the flame through a completely different mechanism.
How does gravity affect the rigidbody in Unity?
Controls whether gravity affects this rigidbody. If set to false the rigidbody will behave as in outer space. Did you find this page useful? Please give it a rating: Thanks for rating this page!

What to do when object falls due to gravity?
If you press the play button, you can see the object falling due to gravity. Next, change the Rigidbody settings, and uncheck the “Use Gravity” option. If you press the play button now, the object will not fall and stay floating in the air.
How do you apply zero gravity in Unity?
In Unity, there is a function to simulate and apply physic laws to objects. By using this function, you can apply rules such as “objects falling due to gravity”, or “objects bouncing on each other”. In this sample, we will use this function to create a zero-gravity effect.
