[this video] . Also, if you want to create a fog of war then you need to change a texture every time fog of war changes. A common solution to this is drawing a very small texture, then scale it, then smooth it, then apply it to view. You can also use a ready solution, here you go [LINK] . But your question isn't quite in the rules of the community. I have found all the tutorials and materials on this topic myself, this means you can do it too!

Cites AlexH · 2019-03 · Stack Overflow · on “Unity: Having the player face the mouse direction. Why does this code work?”

I'm on a simple project following this tutorial [this video] , and one of the first things I need is to have the player point toward the mouse's position. To do so, I wrote this code by following the tutorial: private void Update() { Vector3 input = Input.mousePosition; Vector3 mousePosition = camera.ScreenToWorldPoint(new Vector3(input.x, input.y, camera.transform.position.y)); transform.LookAt(mousePosition + Vector3.up * transform.position.y); } Here's the problem: it works, but I don't quite understand why it works. I read the documentation on ScreenToWorldPoint and am still a little unsure. My question is twofold: Why do I use camera.transform.position.y for the z component of the vector tha

I have a character and some npc's in my game. I want the npc's to look out for my character using a sphere collider. Well it kind of works but of course not as i want. When the npc is looking at me and a colission occurs it should trigger some chasing behaviour, but if the npc look in another direction, it should not trigger that behaviour. So i need something like a field of view inside the collider. I watched some tutorials like [this video] and [LINK] but it should be 3 dimensional so not only on the ground like in the tutorial. I added a picture to visualize it [LINK] How can i accomplish this?

Instead of using ScreenToWorldPoint , I would do something like the following: // Get the camera once. GetComponent is an expensive call, so cache the result whenever // you can instead of calling it repeatedly. Camera theCamera = player.GetComponent<Camera>(); // The camera's far plane gives the view distance float viewDistance = theCamera.farClipPlane; // The camera's current orientation (defined by its "forward" direction) gives the view // direction. Project onto the ground plane to ignore the up/down part. Vector3 viewDirection = Vector3.ProjectOnPlane(theCamera.forward, Vector3.up).normalized; // Get the view width from the camera's field of view float verticalFoV = theCamera.fieldOfVi

Been following this guide [LINK] for Character Controller. This got me getting basic movement working and at time 21:20 he creates a way to rotate the player. [LINK] and this video for the player facing the mouse position. At the 7:15 mark she explains how to get the mousePosition in which I stored it in positionToLookAt I want my character's rotation to be done with the mouse and have a field of view like here: [this video] Been trying to to get it so that the player is facing the direction of the mouse position, but haven't been getting the result. With here showing [LINK] the video results and my PlayerInputs. Some peers mentioned replacing Quaternion targetRotation = Quaternion.LookRotation(p
