@RM-lw2qi 4 года назад

In the game you are showing at 1:18 the light is much smoother than the one we create in this video. Could you elaborate on how you created that smoother effect without hard edges? Really great tutorials btw!

@CodeMonkeyUnity 4 года назад

@@RM-lw2qi The effect in the game is actually done using a different method. Each Survivor has a camera pointing to where they can see, then the depth from that camera is used combined with the main camera to then generate the effect with a shader. The reason why that effect works in there is because that game is 2D but all the Walls and Doors are 3D objects, that method doesn't work in a pure 2D game. However with this method you could create a 2D shader to achieve a similar result.

@PatrickNusbaum 4 года назад

@@CodeMonkeyUnity Would you mind giving a hint on how to create such a shader?

@francoiskrugerpersonal2985 2 года назад

From 18:27 you can't really follow the video anymore :( But here are updated steps: 1) Open Windows > Package Manager & install Universal RP 2) Create a "Rendering > URP Asset (with 2D Renderer)" 3) "New Universal Render Pipeline Asset" is your "LightweightRenderPipelineAsset" and "New Universal Render Pipeline Asset_Renderer" is your "CustomForwardRendererData". I added these names in () to easily follow the video. 4) Go "Edit > Project Settings" and on the "Graphics" tab drag in your LightweightRenderPipelineAsset 5) On the CustomForwardRendererData go "Add Renderer Feature > Render Objects" 3 times and set your settings like Mask, BehindMask and Black in the video That said, I'm still battling to get the stuff working like in the video. Code Monkey or anyone else would you be able to reply with the missing steps I can't get right? It feels to me that the settings in each of the Render Features need to be a little different to your video? Also, I don't know where the "CustomForwardRendererData > Default Layer Mask" setting is anymore?

@billycombo8298 2 года назад

If you download the package for this project, you can imporant the URP files and they work perfectly, you'll just need to change the layers around if you don't have your layers set up the same way he has

@fyodorzaletov3237 Год назад

Hi. I don't think you need any more help, but it might help others. In general, you need to make not a Renderer Pipeline 2D, but a Universal Renderer, which will have Filtering settings. after playing with them and adjusting the layers, you will finally be able to achieve the desired result!

@KOLHO Месяц назад

If anyone has any problems after minute 18:27, just download and install the Universal RP package and continue configuring it, as shown in the video. => Open Windows > Package Manager & install Universal RP Note: make sure that the layers are configured correctly, as shown in the video.

@StixxyTape Год назад

For anyone who was really stuck like me: if the Field of View isn't showing up after setting its layer to mask, then check the material. Make sure it's surface type is set to transparent and not opaque. Worked for me after a bunch of trial and error, so I hope it works for you too! :D

@Emicenizo Год назад

FYI: The combination that worked for me on URP is: Opaque Layer Mask: Default, TransparentFX, Ignore Raycast, Water, UI Transparent Layer Mask: Default, TransparentFX, Ignore Raycast, Water, UI, Objects, Black Also, if you are importing CM's files, keep in mind that the Render Steps on the CustomForwardRenderData may not have the correct Layer Mask by associated (check that on each). Finally, I added the CustomForwardRenderData asset to both the Graphics and Quality menus on Edit > Project Settings > Graphics and > Project Settings > Quality.

@DridgeDEU 2 месяца назад

I felt like I HAD TO wrote how amazing this script is and also thought perhaps others could also benefit from how I learned from this video. After watching the tutorial and following along, I tried to do the same thing again and to do my own script to create this custom mesh. This turned out to be a gigantic task which took me around six hours, and I didn't even get all the things done like defining the angle, having a different starting position and view orientation etc. But that way I really honed the idea of creating custom meshes in code, especially such a complicated one like areas of a circle like you do here. I'm actually a programmer by trade but doing all these mathematical calculations is quite something else; kudos to you that this seems so easy to you and that you even share it with the whole community. I love about your script how versatile it is with the different parameters on top. Truly impressive.

@StixxyTape Год назад

2nd tip for anyone who was stuck like me: If the field of view disappears when the game object goes out of the camera's view, try putting this line of code mesh.RecalculateBounds(); after setting the mesh.vertices/uv/triangles stuff, like this: mesh.vertices = vertices; mesh.uv = uv; mesh.triangles = triangles; mesh.RecalculateBounds();

Always remember that you're not expected to be able to completely follow and implement a tutorial in the time that the video takes. When you see a 20 minute tutorial it absolutely did NOT take me 20 minutes to learn all this and build it. A simple 20 minute tutorial has hours or days not to mention my 20 years of programming experience behind it, so you're not expected to follow along in real-time.

Hello CodeMonkey! There are a couple of things i don't understand very well is this video. The first concerns the render pipeline(18:35). I don't understand very well what you are doing since i dont know much on RP. So, if i got it, based on how you order the layers in the settings it gives priority to one layer over another, am i right? This confuse me because you said that the RP is not rendering the layers that you remove from the list but actually we can see them on playmode. Do you have any advice in order to become more confident with these RP settings? The second is about the mesh bounds. Why the player don't draw the FOV at certain distances?

If I pause the game and click on the FOV in the hierarchy it shows the outline though. However if I take him off the grid it shows up just fine and will work as in intended with the corners of the grid. Thank you for your time.

I do manage to make it work with URP in 2020: -create a new 2d project (without URP) -import the package -install URP -in project settings -> graphic, put the render given in the project -put the mask material alpha higher than 0.5 For some reasons create a project already with urp before import the package does not work (Maybe some LWRP / URP conversion not doing well, have no clue) Also, you need to add a new sprite for the floor (because he is missing)(put the white pixel for instance, don't forget to expand it). You can lower the treshold of the mask shader to 0 to hide it (I don't really understand why but a value lower than the treshold make the mask material unusable).

So i created an object called light source and attached its transform position to the SetOrigin, which I call every update of the mesh script (the one u showed in the video). It doesnt work, specifically the mesh moves faster than the object, making it like every collision has an offset if i move it. Help pls. If instead I just move the walls it works fine.

It's the light and shadow affect I'm most interested in, and how you hide objects using the dark layer, but it seems like I'd need to learn a great deal about Render Pipelines just to implement that one feature? I also have weird interactions where the mesh I have draw is either behind or on top of everything in my scene (usually behind), it doesn't seem to follow the same layer rules that sprites and Canvas based objects use? I've tried other variations, but the ability to "cut a hole" in one layer/image using the mesh you've demonstrated doesn't work with this code as it would with UI elements or DrawLine

@aigen-journey 4 года назад

This might be a stupid question, but why not use lights? for the visual effect (you would also get a nice smooth transition), or a static plane with the light 'cone' taken from a texture?

@CodeMonkeyUnity 4 года назад

That depends on what game you're trying to make, for some games a smooth light might be nice, for other games being able to clearly tell how far you can see might be better. So the question kind of becomes, do you want a lighting effect or a game mechanic? For example in the next video I will apply this effect to the enemies in order to make a very clear enemy view cone, like in Commandos or Desperados, that is perfect for a Stealth game. You can clearly see where you are safe and where you are not.

@@CodeMonkeyUnity As a general comment, I think this is perfect to combine with lights. If you want a FOV environment then lights that are obscured from the FOV (e.g., behind a wall) should not be visible. Lights, once they are in the FOV would be great to illuminate the area. Following this, your FOV angle could be 360 and this would generate a mesh that was then lit as your lights dictated. I went to Google with a notion of how to generate exactly this. I figured it was mesh related, but the exact mechanics I was unsure of. Thanks for this video and others on you channel. Your insight and presentation are outstanding and super helpful.

I fee like you went through the section where you make the field of view actually show enemies a little too fast. Other than that, great tutorial.

@ollewahlstrom1936 4 года назад

Great tutorial! I'm pulling my hair trying to figure out an issue though. Everything works as long as I have alpha on the material on the field of view gameobject to >0.5 which then shows it very clearly green. any lower than that and the green disappears but then the black layer is rendered instead and no object that are supposed to be show in the mask (fov) are shown and it's just dark... I'm so confused. It doesn't help that there seem to have been a version bump since you did this and the version I have so the custom rendering pipeline has some different settings, not much though.

@fartedididnot3685 6 месяцев назад

@@jabbathetrump187 I actually did! I can't remember exactly but its something like this: If you go inside the actual material editor, not sure what its actually called but its a similar look to unreal blueprints. There you should be able to change the color to white, and there should also be a 0.5 option there too. Change that to something much lower and the mesh should appear below 0.5 opacity.

@fartedididnot3685 6 месяцев назад

Hey Code monkey! Mostly everything is working perfectly for me, however I have only one issue. The mask material given from the project is only visible up to 0.5 alpha with green light. Anything lower than that, and it disappears completely, including the behind mask layers. I'm not sure if I may have missed something, or if its an update of unity itself. Any idea?

@CodeMonkeyUnity 6 месяцев назад

That's odd, does it suddenly go from faded green to completely invisible? Try hiding the background, is it still invisible? Maybe there's some sorting issue and when it's under that alpha it renders below the background. Try changing the sorting order or the position slightly

Hey! I had a question; i am working on a 2d multiplayer stealth game, and ive made a playable character who can deploy a smoke bomb, which is supposed to block the line of sight of enemies. But, if i make it solid, players cant pass through it, and if not it does not block players' field of view. Any tips? also, how can i make it so that is a player is using a pre-placed camera-tracker, it would enable a viewcone where that tracker is pointing? Thanks!

@CodeMonkeyUnity 4 года назад

You need to play around with Layers. On the project settings you can define which Layers interact with which, so you can make a layer collide with the Line of Sight but not the player.

For anyone having issues with the FOV origin being offset by a some units, make sure that for the tutorial, you set the FOV gameobject to 0, 0, 0. That was not mentioned in the tutorial in any meaningful way.

How does this work with the new URP in UNity 2019.3? Messed something up. It worked finde in the previous version, but now I've problems

@CodeMonkeyUnity 4 года назад

I haven't tested it with 2019.3 but the URP is pretty much the same as the LWRP so it should work just fine What problems do you have?

@TheKacperuss 4 года назад

@@CodeMonkeyUnity Not the same guy and 3 months late but I was also working on 2019.3 with URP. In my experience, for some reason the stencil override option just ticks itself off when running the game, effectively removing all changes. I couldn't find any solutions or even anyone mentioning the problem. Both depth and camera options work just fine, but stencil resets each time you try to run the game. I tried it on 2019.2 and I can confirm it works fine, it's not me being stupid. It really seems that something in URP in 2019.3 causes stencil to be... Ignored? Skipped? Reset? Turned off? I'm sorry if you already discussed this problem. I couldn't find any of your latest videos being about render pipelines, but maybe I missed something.

@Username5278234 Год назад

Howdy there! Kind of a niche question, and I know this is an old video, but I figured I don't know where else to go. My FOV works beautifully, up until my player collides with a moving object ie the bullets my enemies are shooting. Then the vector from angle and angle from vector float suddenly start changing rapidly within a small margin, which results in a flickering of the fov's borders, seems to be rapidly changing position. I found I can resolve this by pressing my character against a wall until the values normalize, but my player character is not moving, nor the origin, nor the aim direction while this is occurring. Super specific, but any insight would be wonderful, thanks!

@CodeMonkeyUnity Год назад

Since you say it happens on a collision maybe your player has a rigidbody and is being pushed back when hit by something? There's nothing in this specific code that should cause any jitter like that. Add some Debug.Log to see what the code is doing but it doesn't sound like the issue is related to this FOV code

@michiblk4581 4 года назад

Is it possible to let already passed sections stay revealed? I currently make a map where areas which are already were seen is visible.

@CodeMonkeyUnity 4 года назад

For that you need something different that can store what areas have already been uncovered. The simplest way is just a basic grid with a bool for visible or not and visualize by showing or hiding a black visual for each grid position.

@davidwarneke3469 3 года назад

When you set up your GetVectorFromAngle() method, where you tell it what to return, put a 0 between the mathf.cos, and mathf.sin, so that it works on the x,y, and z axies.

@davidson2727what 3 года назад

I know this is a late reply but making in this in 3d required me to write my own GetVectorFromAngle function. In that function this is my return statement "return new Vector3(Mathf.Cos(angleRad), 0, Mathf.Sin(angleRad));" The mesh is on what is the 'ground plane in 3D' but its facing the wrong way, this should be fixed later once it is attached to the player. Hope this helps you or someone else.

So I am trying to use this code for an enemy to detect a player, but I can't figure out a way where it detects the player and starts the enemies follow script without it stopping if it sees a wall. Currently I have these lines of code within for (int i = 0; i < rayCount; i++) if (raycastHit2D.collider.CompareTag("Player")) { enemyScript.canSee = true; } else { enemyScript.canSee = false; } and if you couldn't tell this makes it so if it sees a wall and the player it stops. Is there a better way for me to do this, so the enemy won't stop if it sees both a wall and the player?
