To do that, let’s create a new script and name it AI.cs and copy the following code.
We can finally make our character move around the platform.
Now that we finally have our scene baked with NavMesh. Let’s start making our character move around on its own. If we try to bake our scene we will have this. Let’s say we have this surface where the character can climb onto. Now, what if you have a high-leveled surface? Once done, select the NavMesh game object once again and hit Bake again.Īs you can see now, the character is not included anymore in the NavMesh. In our case, we have an Environment game object which contains all of our walls and floor. Change its layers from whatever layer it is currently into to Platform. Next, select the Character game object, go to its inspecter and change its Layer from Default to Character.ĭo the same for your environment game objects. Go back to hierarchy and select NavMesh game object once again and go to its inspector and under the Include Layers dropdown, unselect the Character layer. Next, input Character and Platform on Layers To do this, navigate to your hierarchy, select the Character game object and go to its inspector and select Add Layer… under the Layer dropdown. And so to prevent this from happening we need to layer our game objects.įor the character we need to layer this as Character.įor Platforms, we need to layer them as Platform. You will have the following output.Īs you can see, the NavMesh also treated our character as an obstacle. However, if you try to put it down the safe with the walls. If you didn’t notice, we have raised the red cylinder a little high so it won’t get affected by the baking process. Next, proceed to NavMeshSurface component and you may actually click the Bake button to bake your scene.Īs you can see in the scene view, it perfectly created a blue-tinted area and this area is only where the character can walk onto. With the NavMesh game object selected, navigate to your inspector and click the Add Component button and look for NavMeshSurface. To allow it to bake the scene, we have to add the NavMeshSurface component. This game object is going to be responsible for baking the scene’s NavMesh. To do that, we’ll first create an empty game object which we’ll name NavMesh. In order for our character to be able to move around the environment, the scene must be baked with NavMesh so the character can determine which area he can walk and which area he can not walk onto. Simply extract it and import the folder to your project like below.

In this tutorial, we’ll be diving into how to create a game character that walks from one position to another using the NavMesh Surface component which will allow us to define a more accurate surface for our characters to walk into.Īlso, are you looking for an AI Behavior package that will help you complete your games? If so, then we recommend you try the package below. Thankfully, Unity provided a solution that allows game developers to add a pathfinding system that gives game characters the ability to walk around the environment and it’s called NavMesh navigation system. How do you actually implement a path finding for games? This is also the same with game path finding. Given two points of location, the system will compare the distance of each point and will look for the shortest path.
Pathfinding is also not just used by games, it is also used by apps like Uber. If the character wants to move from one location to another, the pathfinding system will process its way and give it a path that the character can follow. In most games, enemies are often allowed to roam around the game environment.
