- Video Description -
This video is mainly focused on giving vision to our AI by creating a script which will allow it to detect if it can see the player, we will use some simple maths to detect if the player is in the radius of the AI, then check if the player is in the view angle of the AI then we will make sure there are no walls blocking the sight and after all that we will know that the AI can see the player! :) Then we will also be improving the jump of our character to make it more realistic and fun to use :D
- Series Description -
This series was built to be an entertaining way of learning Unity while making an incredible game, you will learn how to make complex AI behaviour and write complex scripts such as custom character controllers w/ custom handled collision and slopes and Editor Code to control behaviour. All being essential skills to being a Pro Unity Developer.

Thank you for this amazing video , allow me to edit your code since most of scenes has lots of colliders , the array will not fit more than 10 objects , if u wanna increase the array size for example 50 this will cause memory leak , the solution is : 1- I've added : public float heightMultiplayer = 1.5f;// this will move the post raycast up. 2- move inFOV to inside fixedUpdate method. public void inFOV(Transform checkingObject, Transform target, float maxAngle, float maxRadius) { Vector3 directionBetween = (target.position - checkingObject.position).normalized; directionBetween.y *= 0; RaycastHit hit; if ( Physics.Raycast(checkingObject.position + Vector3.up * heightMultiplayer, (target.position - checkingObject.position).normalized, out hit, maxRadius)) { if ( LayerMask.LayerToName(hit.transform.gameObject.layer) == "Player") { float angle = Vector3.Angle(checkingObject.forward + Vector3.up * heightMultiplayer, directionBetween); if (angle

Hey man, we're all definitely waiting on the new stuff! I hope you aren't going to hard and getting overwhelmed, it's okay to limit the scope of these videos so that by the end we have created something substantial and good! I myself have been taking the character controller you've made here and applying some stuff to it for my own sneak functions. Maybe it would be good to make a video setting the scope, setting exactly what kind of character controller we want for exactly what kind of game we are making, so that we can refine to that end. I really hope you aren't getting discouraged because I've been waiting for that new vid for months homie! Cheers!

@michaelgreenhut180 4 года назад

Maybe I set this up wrong or missed a step, but I wouldn't call Jump() every frame and then check for a spacebar press, I'd do it the other way around - it might take more setup, but it would be worthwhile. Among other things, the grounded variable is toggling every other frame or so with this setup, and pressing space is therefore ineffective half the time. But I could have forgotten to tweak something. Otherwise, awesome code.

@callumweaver7013 4 года назад

how would i adapt the code to shoot out more rays than 2 that are all in the angle range, as for some reason it only trigger the isInFov when it overlaps with the rays, not inside the angle range.

THANK YOU for this great enemy sight tutorial, this is the forth and only video that I have seen today that really does the job.

@batchprogrammer108 5 лет назад

You are absolutely right, that is a good idea as well!

@PakGrantChristie 6 лет назад

I don't think my last post was saved. I am really keen to see whether you get to implement and over the shoulder aiming function to your camera. While aiming, is it possible to operate your pitch and yaw and movement functions from a behind the players shoulder. Or do you have a better ways to do this :) Keep up the great work AJTech.

@batchprogrammer108 6 лет назад

Oh wow that's an awesome idea! I have not yet played with these features but I will try my best to implement everything that you have suggested, and yeah maybe it didn't save because I didn't see it sorry. I will upload that as my next episode for sure :D Thanks again for your idea :)

@batchprogrammer108 6 лет назад

Okay so I played around with this feature and it seems that it would be better to implement this system after we have a player model and I would like to add that after getting a few core features of the game done, so thank you so much for suggesting this and I will certainly be posting on this idea in a few episodes, sorry about that :( Thanks for suggesting though :)

@PakGrantChristie 6 лет назад

Thanks so much for looking into it and I totally understand. I am using a character in my prototype and have it aiming up and down based on the mouse. I have used a second layer in the animator for the aiming up and down animations using weighting - I switch it to 1 when I am aiming. I initially stopped the camera from controlling the player's rotations using a bool but that meant the player was only aiming up and down but I had no control pointing the player left or right. I thought if I toggled the target position of the camera to an empty game object childed just behind the right shoulder while aiming, that might allow me to keep the camera as the controller of players movement while aiming but alas I am not clever enough to work this out :(. But I will be patient and see how the controller progresses and it is clear we are in very good hand with you AJTech. I have already learn sooo much after 4 episodes so thanks mate :)

@batchprogrammer108 6 лет назад

Hey Grant, I'm sorry to hear that you are having trouble with this :( I can understand your pain, I initially thought this would be simple to implement until I got into it. I think I may be quite close to getting a solution to this problem. I made a very simple model in Blender with arms and I will be coding a simple Inverse Kinematic solution to make the arms bend and always hold the gun then I should be able to rotate the gun and the player using the Camera Controller script and get a nice looking aiming function. I'm not 100% sure if this will work but the next episode might be a bit delayed so I can get this working properly. This is my first time playing with IK as well so I'm not sure about how well it will turn out, but I hope I can get this working for you :) Glad to hear that you are learning from this series :) Thank you for the support :)

Hey can I ask why you use overlapsphere instead of Distance? I got it to work with distance and seem easier to me.

Of course distance would work as well, but you have to query for certain objects I generalize the problem by checking for all objects within a radius

@dingaloo1056 3 года назад

Hey, quick question for anyone who can answer: isn't it a bad idea to use detection through onDrawGizmos? It was my understanding that this wouldn't run at all in an actual exe of the game, it was just for testing purposes. thanks! edit: I just made an exe of my game using this method, and indeed, the enemy does not detect anything with this method

I have been having some issues with the code. For some reason whenever I run the program I get two different problems. The gizmos has a problem that causes an error saying. "Gizmo drawing functions can only be used in OnDrawGizmos and OnDrawGizmos selected UnityEngine.Gizmos.DrawWireSphere" The other problem is whenever the AI sees me it teleports me to it. The only fix I've been able to get is to get an indexoutofbounds error. Am I missing something in the code? I had copied the exact code down to the letter and it still doesn't work.

@DJLKM1 5 лет назад

Hey Ajay, i have an issue with my project and not really relative to this video sorry, not sure if you can help. The floor prefab tiles im using for indoor flooring are quite small (1x1 ingame meter), the character keeps dipping into the floor while walking across the floor, i thought it was due to the mesh colliders having a tiny gap between them so i made sure it was all snapped right, but its still happening. My second idea was to put a dummy ground plane a hair height under the whole floor, this didnt work either. Any ideas would be awesome.

@batchprogrammer108 5 лет назад

Are you using the controller that is used in this video? Because if so, there could be a few issues -- are the colliders on the player set up properly?

@DJLKM1 5 лет назад

Hi @@batchprogrammer108 Yeah im using your controller and its setup exactly as you have here (up to tutorial #6), i also have found another issue, it to is a collider issue. your controller is totally custom and doesn't rely on any unity control components which is admirable. But unless im missing something stupid; Trigger colliders or trigger zones do not work with your controller as the unity engine is expecting a rigidbody to enter the collider in the OnTriggerEnter methods, so im a bit stuck lol

@batchprogrammer108 5 лет назад

@@DJLKM1 Oh that is a very interesting problem, I'm not exactly sure what the answer to the previous question is but for this one, one simple work around could just be to add a child object to the player and attach a rigidbody and trigger to it, but this is a workaround. This controller i made is to show people the different features that unity has but if you are building a production level game i highly reccomend building a player controller that implements rigidbodies as they have very high fidelity collision support. I have actually built yet another controller that uses full rigidbodies however i manage things such as gravity and jumping without rigidbodies. Hope this helps :)

@batchprogrammer108 6 лет назад

Oh okay.. Hmm, that's very difficult because there could be a lot of things that could be going wrong. You can try : Making sure your player has a collider, make sure you're actually calling the 'inFov()' method, but I am sure that you have already done these things. I apologize but I can't really help without an understanding of the situation, maybe you could go to this link - github.com/AJTech2002/Stealth-Series/blob/master/Parts/Stealth%20Game%20Part%204/Assets/Scripts/FOVDetection.cs and just check if the code does really match up, because sometimes the small little mistakes matter. I hope this helps :)

@tristunalekzander5608 6 лет назад

Thanks for responding :) I subbed because of it. I couldn't find a difference so I just copied and pasted your code and it still doesn't work. Everything works except the player isn't being detected and inFOV isn't returning true like it should. (Just so you know, I did put the player object into the public player transform and have increased the maxAngle and maxRadius so I can see the gizmos) One other thing, I can't see the gizmos in-game. I thought that was normal but you seem to be able to see them while playing. Idk if that would help you figure out what I am doing wrong. I also didn't watch your other videos in the series, is there another script needed to make this one work or something?

@batchprogrammer108 6 лет назад

Tristan Thank you for the sub Tristan! Firstly this script is 100% independent so it should work alone, secondly on the topic of rendering gizmos in Game view, that is actually an option you can enable and disable. In your game view look at the option buttons just above where the ‘Maximise view’ buttons are and select the option ‘Gizmos’ and it should draw the gizmos. Now i do have one question that could clear things up, are you using this script in a scene with a lot of game objects? Because we set the collider buffer at 10 and if there are more than 10 objects in the sphere radius before the player enters it may not be detected. My entry and Debug.Log what objects are being detected and what isn’t. If this is the issue just try and increase the collision buffer from 10 to something that suits you. Then if that doesn’t work, just try Debugging every step of the inFov code and see where it stops just to get an idea. Also make sure that you Debug the ‘count’ variable so we can see if it even knows the player is in the radius. If it doesn’t then either increase the buffer size or we have some type of a issue. When i mean buffer size I am referring to this line ‘Collider[] overlaps = new Collider[bufferSize]; . I really hope some of this helps you out, just give me the results of your debugging journey and we’ll try figure this out. Have a great day :)

@tristunalekzander5608 6 лет назад

AJTech For some reason it only works in game mode lmao. After I turned on the Gizmos to visible in game mode the red line did indeed turn green when I moved within its range. So it does what I want it to now but now I'm curious why it doesn't work in the scene view? Also, thanks!!!! :D

@batchprogrammer108 5 лет назад

Hm, so there could be a few issues - The ray could be colliding with the player/object that it is coming out of or maybe the layers haven't been setup properly. Could you create a Debug.Log in the Physics.Raycast & see what object it is actually detecting or is it not detecting anything?

@creeper20ps 3 года назад

Its giving an error because the array is too much smaller than the colliders that its detecting. The array in that script is: Collider[] overlaps = new Collider[10]; That Wireframe yellow sphere. Inside that, it'll detect any object that has a component of a "Collider". So let say.... you have the floor and the player..., that's two colliders. If you go beyond 10 colliders inside the yellow sphere. It'll give you an error. So plan it out. If you think there's going to be like 30 object or more inside that yellow sphere, that has a component collider. Change This: Collider[] overlaps = new Collider[10]; To this: Collider[] overlaps = new Collider[40];

I was able to get it to work on my project as well Unity 2019.3.9f1. I'm trying to now modify it to work along the X-axis as well to make more of a cone view so If anyone has a way to do that I'd love to hear it. @Davers if you're still interested share your code and I'll compare it with mine.
