Joined: Aug 14, Posts: Hello, I'm fairly new at using Unity I've watched several tutorials so I could get a better understanding for programming and utilizing Unity. I've looked to Google to educate myself on the issue I'm having with navigation and baking a NavMesh on a terrain.

I've created a small low poly open world for a little project I'm using to practice a small playable RPG. Is there anything basic that I'm totally missing that's causing my almost completed low poly world terrain to NOT work?

Any suggestions would be greatly appreciated.

You can find this option from Inspector upper right corner to include it into navmesh.

Then bake it.

I cant seem to find any source that says i can.

DoublePixelStudiosNov 28, Joined: Feb 26, Posts: If i remember correctly there are some guides that specifically say that it's not possible using the navmesh. But you can do it yourself. Assuming your platforms aren't too complex not whole buildings flying around, but just simple shapes like a circle or a rectangle then you can simply hard-code the locations where an NPC goes onto a platform etc That's what I'm doing and it works well enough since I realized I don't actually need my NPCs to path-find their way around while on the platform.

So not having a mesh there is fine. Just take care that the geometry is simple basically that means no obstacles on the platform object that where a navmesh would be needed.

Joined: Apr 11, Posts: 26, Assuming the platform has geometry requiring navigation why else would anyone use navmesh on it? For a boat or something. Joined: May 2, Posts: I have come just across this too. For example I have a bridge which tweens into position when triggered, but it looks as though I can't add this to the navmesh. Any tips or ideas would be appreciated. TheMonkeysaurNov 28, Or you can wait for when if Unity want to tackle it.

So basically if i have a square. I get that once the navmesh is baked than it is baked into position, i just didnt know if there was a possibility to unbake it in runtime using a script to allow the platform with navmesh on it to move in any direction from script I finally understand what you are saying.Select your preferred scripting language.

VinnieNov 9, Apparently the problem with navmesh in 2d is the coordinates. People with a lot of time on their hands have figured out how to switch the coordinates around. Joined: Oct 5, Posts: 2, GameDevCoupleNov 9, Apparently, it's theoretically possible for this to work, however, it's not feasible. You will need to rebuild your scene in 3d and rotate all game objects to face xz instead of xy.NavMesh A mesh that Unity generates to approximate the walkable areas and obstacles in your environment for path finding and AI-controlled navigation.

A GameObject can contain any number of components. Unity has many built-in components, and you can create your own by writing scripts that inherit from MonoBehaviour.

More info See in Glossary provide you with additional controls for building also known as baking and using NavMeshes at run time and in the Unity Editor. The high-level NavMesh building components listed below are not supplied with the standard Unity Editor installer which you download from the Unity store.

Instead, download them from the Unity Technologies GitHub and install them separately. For more information on Agent types, refer to documentation on creating NavMesh Agents.

For more details about NavMesh area types, see documentation on NavMesh areas. Note: Make sure to back up your Project before installing high-level NavMesh building components. Version: Language : English.

Unity Manual. Unity User Manual Building a NavMesh. NavMesh Surface. Publication Date: NavMeshAgent components help you to create characters which avoid each other while moving towards their goal. Agents reason about the game world using the NavMesh A mesh that Unity generates to approximate the walkable areas and obstacles in your environment for path finding and AI-controlled navigation.

More info See in Glossary and they know how to avoid each other as well as other moving obstacles. The agent is defined by an upright cylinder whose size is specified by the Radius and Height properties. The cylinder moves with the object but always remains upright even if the object itself rotates. The shape of the cylinder is used to detect and respond to collisions between other agents and obstacles.

When the GameObject The fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more.

The height and radius of the cylinder are actually specified in two different places: the NavMesh bake settings and the properties of the individual agents. Most often you set the size of the agent the same in both places. Version: Language : English. Unity Manual. Unity User Manual Nav Mesh Obstacle. Publication Date: Radius of the agent, used to calculate collisions A collision occurs when the physics engine detects that the colliders of two GameObjects make contact or overlap, when at least one has a rigidbody component and is in motion.

More info See in Glossary between obstacles and other agents. The height clearance the agent needs to pass below an obstacle overhead. Offset of the collision cylinder in relation to the transform pivot point. When enabled, the agent will slow down when reaching the destination. You should disable this for behaviors such patrolling, where the agent should move smoothly between multiple points.

Obstacle avoidance quality. If you have high number of agents you can save CPU time by reducing the obstacle avoidance quality. Setting avoidance to none, will only resolve collision, but will not try to actively avoid other agents and obstacles. Agents of lower priority will be ignored by this agent when performing avoidance. The value should be in the range 0—99 where lower numbers indicate higher priority. Set to true to automatically traverse off-mesh links. You should turn this off when you you want to use animation or some specific way to traverse off-mesh links.

When enabled the agent will try to find path again when it reaches the end of a partial path. When there is no path to the destination, a partial path is generated to the closest reachable location to the destination.
