## How do you make an obstacle in unity?

1. Go to Project > Images > Asteroids and select any asteroid and drag it onto Hierarchy.
2. In the Inspector, click on Add Component and add a Rigidbody 2D and set the Gravity to 0 and the Friction to 1 to ensure that the asteroid will stop moving after a short distance.

## What is a NavMesh obstacle?

The Nav Mesh__ Obstacle__ component allows you to describe moving obstacles that Nav Mesh Agents should avoid while navigating the world (for example, barrels or crates controlled by the physics system). While the obstacle is moving, the Nav Mesh Agents do their best to avoid it.

What pathfinding does NavMesh use?

Games often represent the pathfinding graph with a mesh. That is, just like a 3D model, the graph used for pathfinding can be represented with vertices connected by edges. A mesh like this is called a Navigation Mesh, so Unity’s tech for this has the abbreviated name NavMesh.

What is the purpose of the NavMesh modifier?

NavMesh Modifier Volume is useful for marking certain areas of walkable surfaces that might not be represented as separate geometry, for example danger areas. You can also use It to make certain areas non-walkable.

### What is NavMesh in unity?

A NavMesh is a designated mesh in your Unity scene, which specifies navigable areas in your environment, including areas where characters can walk, as well as obstacles. This is useful for scenarios which incorporate pathfinding and AI-controlled navigation.

### Is Unity pathfinding deterministic?

That is due to the fact that we use Unity’s pathfinding as underlying technology which works not deterministic at all.

What is A NavMesh graph?

The Navmesh Graph is the other main graph type. This graph expresses the pathfinding data as a triangle mesh instead of squares (Grid Graph) or point (Point Graph). This is perfect for smooth and fast pathfinding where the graph doesn’t need much changing during runtime.

How do you get random points on NavMesh?

How to get a random point on NavMesh?

1. randomDirection += transform. position;
2. NavMeshHit hit;
3. NavMesh. SamplePosition(randomDirection, out hit, walkRadius, 1);
4. Vector3 finalPosition = hit. position;

#### How do you make a trigger zone in unity?

There are a few solutions to make a trigger zone. The best one is to create a empty object and add a Box Collider component. Then on the Box Collider you set the “Is Trigger” value to true. Now add a script to the trigger object and in this script, remove “void Start” and “void Update”.
