Use a 3D Cube GameObject or other mesh to mark the areas, you wish to classify as a higher cost. You can create new classifications for areas under the Navigation Window in the Areas tab. Visit Unity’s article to learn more on setting up Not Walkable or higher cost areas. As Unity calculates the shortest path between the two points, you may want to set up Navigation Areas and Costs which can help improve pathing as shown in the images below. You can now author a calculated path between two points by creating destination points. Proceed to press Bake again for an updated overlay.

Setting the mode to DEVICE may offset the NavMesh agents' positioning at runtime. See Spatial Frame of Reference on how to change the mode. Set the ARCamera's World Tracking Mode to FIRST_TARGET if you are using a single Area Target or specify an Area Target as SPECIFIC_TARGET to centre the world origin around it.Your imported Area Target will either appear as a textured mesh or a point cloud.
Open your Unity Project and set it up with Vuforia Engine, ARCamera GameObject, and your Area Target imported as a Unity package.You can use Unity’s navigation system to detect and define walkable ground on your model or point cloud and proceed to create static or dynamic navigation between the user and points of interest (POI) in your Area Target application.įollow these steps to set up your mesh for navigation:
On Unity's official webpage, they have a Navmesh tutorial you should look at.One of the applications which Area Targets support is navigation. If you have one of the ghost flying enemies, you can just give them a separate Layer and disable collisions with those types of enemies in the Physics setting so you can run through them. Once you implement that, you have the closest thing to Diablo, the rest is just implementing RPG aspects like attacking and abilities and inventory, items, etc etc.ĮDIT: I think Unity's Navmesh covers local avoidance, so your character will be able to take into account other characters and enemies, so you wouldnt be able to move past a wall of enemies down a hallway. Or, you can use a Ra圜ast that hits the terrain exactly where you clicked (if you left-click in Diablo, you move exactly where you clicked), then you can retrieve the Ra圜ast to get the position, then use pathfinding to find the closest walkable node there. Left and down would just be those variables * -1 to flip them. To get camera direction, you can cache the variable directions like for up, for right. You can either use camera directions and get a direction then make an imaginary Vector3 target position in front of the player in that direction (like if youre holding right-click to move like in Diablo, the player heads in the direction of your mouse). Implement a controller that attempts to get the pathfinding target as a Vector3 position and pathfinding will make your character head to target position (going around obstacles) and if your position is in an unwalkable area (like you clicked ontop of a wall) it'll get the closest walkable node.

Make a Navmesh or (if you're not using Unity's built-in pathfinding, use Aaron's A* project which has a free version). This is to ensure if the player is running against obstacles (walls, trees) that have IsTrigger colliders, then this will stop the CharacterController from moving through them. Make a character with a CharacterController
