Thanks a lot!

Thank you 🙂

I will try tackling the multiplayer soon 🙂

Thanks 🙂

Thanks! 🙂

You are very kind 🙂 Thank you for your support 👍

Thanks! Next part should appear today 🙂

I will cover how to place floor and on it furniture (or rather how to place both) and how to detect when deleting the furniture first and next the floor. Stacking would be done similarly - detect IF there is a floor and only then allow to place furniture. You should have really easy time figuring it out when I release the "Removing objects" part of the tutorial 🙂

Unless you need a continuous placement you could still have a flat 2D grid since even if you are selecting a mountain its X and Z coordinates are the same as on the flat area. All you would need to to is shoot a raycast from the edges of your object to place it at an angle relative to the terrain shape. The easier approach would be to shoot a raycast from the center point and place it at this altitude. You would also need to use some form of a boxcast against your terrain to check if by any any you are not intersecting a mountain edge when placing your object. Can be a lot of work to implement this. I hope it helps!

You could have a custom grid that supports it. Most times you would make the cells of a size that can fit your object. The size is 2.75. You could make it occupy 3 tiles of 1 unit of size or maybe make the cells have 0.5 unit (which doesn't changes much but maybe you have other objects that are 2.5 and here it does make a difference). I would suggest to adjust the size of your grid to to the smallest object that you have .

Hey! in the code we are relying on the "grid.CellToWorld(gridPosition);" so the method from the Grid class. Any offset might be caused by 1) offset added to the GRID object in the hierarchy or 2) offset added to the cell indicator prefab or 3) some error in the code. You can view the code here github.com/SunnyValleyStudio/Grid-Placement-System-Unity-2022/commits/main I hope it helps. if not feel free to write me on discord (link in the description) and attach screenshot so i have a better understanding of the problem 🙂

@@SunnyValleyStudio Hey! Thanks for your quick answer, I made sure that every prefab and the grid start at 0,0,0. I fixed the problem by adding 1 to each the x and z position to the cellindicator position. Other than that everything worked fine, thank you for this awesome tutorial!

Flickering can be cause by z-fighting (that is why we move the grid plane in front of the ground). When you zoom far away the flickering can be dues to Anti-aliasing and the fact that our grid is "thin" when viewed from afar). I'm not an expert when it comes to solving graphics related problems so it's something you would have to research 🙂

Can be some changes done to the Shader Graph docs.unity3d.com/Packages/com.unity.shadergraph@6.9/manual/Object-Node.html . It shouldn't affect the shader that we create though 👍

It sounds like anti-aliasing issue. You can try making your grid thicker but I'm note entirely sure what do you mean by jittering. Feel free to share screenshot on discord.

I really appreciate the feedback 👍

Thanks for the feedback!

Hey! Yes you can do it. I show how in my House Building Template courses.sunnyvalleystudio.com/p/house-building-system-in-unity to encourage people to support my work 🙂 It isn't hard to figure out. It just takes a custom script.

Strange. I remember that indeed some parameters had to be limited in range from 0 - 0.99 because otherwise the shader logic would not work. Maybe I forgot to add clamp node to prevent that. Sorry about that! I'm fairly confident about the shader itself so if it is not the issue that you are experiencing maybe take a look again at the section of the video where I present the graph and compare it with yours. Feel free to join my discord discord.com/invite/RQEtYHz if you need me to send you a screenshot of my graph 🙂

I am not sure. It might be something connected to rendering settings. I am not that advanced with fixing visual bugs. Very often it can be connected to Anti Aliasing but again that is just what I would check.

@@SunnyValleyStudio okay thank you. Do you know if you're experiencing the same thing?

Are you using URP pipeline? Another reason for it might be that you have created a default shader file and not the "Shader graph" asset. You can check this forum to read more about this issue forum.unity.com/threads/cant-open-shader-graph.669955/

This is because we only get half of it on the edges. You could use a Rectangle nod and add a thicker outline to the edges of the plane - just have to find the correct value based on the scale and the base thickness. You could just use "Add" node to the result that we have so far and for safety "Clamp" it to 0-1.

I will be talking about the prefab in the next video. The prefab is of size 1x1 (grid cursor indicator). Then we modify the shader size it doesn't affect the Grid component. We have to manual (you can use a customs script) set the Grid component size to 0.5 when you set the shader size to be (2,2,2) - because we multiply there and 1 / 0.5f = 2. Anyhow the only moment that your cursor should move is when we modify the Transform of the "Grid Parent" object since it applies offset to the Grid components calculations. I hope it answers your question 🙂

Thanks! 🙂

The easiest way is to specify by hand the grid borders (later you can calculate those). Next just ask this "GridB0rders.cs" component "Are the positions selected for placement outside the grid border? " All you would have there is a "center point" and the "size" and single method with an if stement "If origin.x + offset.x < placement.x .. " (the same for negative offset and the y value). I hope it makes sense

@@SunnyValleyStudio Yep I kinda figured it out by taking limits of the Grid then doing something in the CalculateGridPositions(); function like Vector3Int desiredPosition = gridPosition + new Vector3Int(x, 0, y); if (desiredPosition.x < -gridXLimit / 2 || desiredPosition.x > (gridXLimit / 2) - 1 || desiredPosition.z < -gridYLimit / 2 || desiredPosition.z > (gridYLimit / 2) - 1) { return null; } and then in the CanPlaceObjectAt(); function if (positionToOccupy == null) return false; Solved the thing 👍

Fixed it. It was a renderer issue

Glad to hear that you were able to solve it 🙂

@@SunnyValleyStudio Great Guides! Thanks!

I found the answer of the first: Material > Sorting Priority -1

Good to hear that you have found a solution!

Do you know how to control the grid alpha/transparency?@@SunnyValleyStudio I tried the color, but it doesn't do anything.

If you mean for the shader Grid parameter you have to open Package Manager (from the Top menu I think "View" category ?) and find in it the Shader graph. Next on the right you should find "samples" and have a way to download the shader graph samples.

I believe that we use URP in the project. Still this is definitely a shared problem where you fix it by swapping the shader of your material to a compatible one.

Thanks for the comment! 👍

What do you mean? We create the grid in the tutorial
