How do you detect collisions without rigidbody?
There is an option to add ‘isTrigger’ property in any collider and you can listen to TriggerEvent in your script. This will work without having a rigidbody at all. But you do need to have colliders on the objects that have to collide.
Does On collision Enter need rigidbody?
It doesn’t have to be an non-kinematic rigidbody though – so if you have objects you don’t wanna do physics (like gravity) for, you can attach a rigidbody still to it, and set the kinematic checkbox. Then when that object hits your trigger or another object with OnCollisionEnter then it should work.
What is collision JavaScript?
In JavaScript, a collision occurs when two or more HTML elements collide. By default, when using a move event listener on an HTML element, it will not hit any other element on the screen. It will pass through the other elements in the DOM.
How do you implement a BVH?
BVH Algorithm
- Create a root node.
- Create an AABB box bounding every object in the scene.
- Assign the AABB box to the root node.
- Find the AABB longest axis and sort each object along this direction.
- Find a (split index) midpoint that divides the bounding box.
What is Broadphase?
Typically, a broadphase keeps track of bounding volumes, usually AABBs, of all colliders. The broadphase produces a list of collider pairs whose AABBs are colliding. These collider pairs are then passed on to the collision detection algorithm to decide whether they actually collide.

Is character controller better than rigidbody?
Basically, Rigidbodies deal with physics and the Character Controller (as far as i know), does not. So if you want to deal with irregular slopes and pathing, using physics to push rigidbodies is best. If everything was perfectly flat with no slopes, a character controller would be fine.
What is the difference between on trigger enter and on collision enter?
An easy way to differentiate between the two is to think of them visually. OnCollisionEnter can be visualized as colliding against a wall, and OnTriggerEnter can be visualized as triggering an alarm. Let’s take a look at them individually.
