🌐 Have you found the videos Helpful and Valuable? ❤️ Get my Courses unitycodemonkey.com/courses or my Steam Games 🎮 unitycodemonkey.com/gamebundle 💬 Here's a really awesome Building System that you can use to build anything, doesn't have to be actual Buildings. You can use it in a RTS, Factory game, Survival, etc. In fact I'm currently working on a Factory Automation mini-game where I'm using this system as a base for placing down all kinds of objects! It's super versatile so definitely look forward to many more videos using this system as a base! What do you imagine you can do with it?

I appreciate the videos, but they're extremely difficult to follow and implement due to: 1) Code structure changes between videos with no explanation 2) No explanation on how they're used in a particular scene (I realized that earlier videos depended on a 2D scene, later ones a 3D scene that's not compatible with earlier setups) 3) The source code links require registering for your website (annoying), and once downloaded the file is a unity bundle that then must be imported into unity to read, and also it's just one big cluster of random files and projects. The file I was looking for is a completely different name and structure as well from what's covered in the videos. Would be far better to just place source files in github and to not deviate from the format or naming at all.

I kinda agree with all of this. The grid things just kind-of grew over time, and later tutorials even just go about the "approach" rather than "1:1 follow the code" thing. Which I think is fine to a degree. But following along/checking out the source code is extremely annoying. I'd love to: 1) Redo the things aimed at more experienced users (like having the TGridObject fire an event when the value changes and have the grid be able to subscribe to it to loosen the coupling etc.) 2) Provide a GitHub with multiple branches being multiple-steps for people to check out themselves with clear-cut foldernames for ease of access I know making a lot of money is important to you and there's this whole youtube buzzwords and keeping videos short thingamajic going on. But if that is an issue, a multi-part series would be maybe cool too. Or just livestream it all and hire a dedicated editor for it? But bottom line is, I'd love for the codes and all to really just be on a public repo for people to check out with some clear-cut instructions. Said 'instructions' could be as simple as just making dedicated/'calculated' commits, each representing a new feature. That way one could compare files and what changed easily and also follow your new style of "tutorials" more easily. In fact I think I like that easy enough that I'll try commenting/suggesting it on a newer video for visibilities sake. As for 'converting' it from 2d to 3d, it's really just a change of the coordinates, or alternatively this video: kzread.info/dash/bejne/Za6stsugmq3YYpc.html

Hello, so I have some advice for those using unity version 2022+ just incase you having some issues, 1 -- when downloading CM's assets for any of his videos if you already have script's with the same naming structures both Unity and Visual studio are going to throw a fit, simple fix is to use /* above the using statement's and */ at the very last line of the CM script's, this clear's most of the issues in the project for the script's and still allows you to use them as reference when solving issues, 2 - if you import the scene it can some times have issues that I haven't found a fix for, best to not import that and simply rebuild the scene normally doesn't take very long, also don't import anything that say's URP or Setting's for some reason this causes issue's I'm not sure why Better to just import URP into your project or, start a project already setup for URP, 3- best way to add your own prefab's to replace pink/purple issue with visual's is to use the same structure as CM, by adding a prefab with the logic, then having the script logic instantiate the visual of your choice as a child of the parent(what the logic script is attached too), then changing what's needed in your script's to fix any other issues that are still persistent, as for an easy ghost prefab can just have the material set to 50% or so transparency and then have it set back with code after the prefab as been placed/Instantiated(this worked for me, might try it urself), 4 don't forget to also download and import CM's util's, or build some of your own with the same naming structure to prevent having to change a ton of code.. if u have other issues after doing this I apologize as I'm still new to a lot of this as well and not sure how to help, Sorry this was a mouth full! Ps. CM in the part of this video where you check to see if a building is occupying multiple point's on the grid, is there any advice you can give if I wanted to check if a unique oddly shaped object where to be rotated and which part's of the grid where at the closes co-ordinance and then make the grid with a value of Range(x etc.) or a bool of T/F change the underlying grid values, I've been trying some ideas on my own to get this to work with no success so far, any advice would be helpful. With that said, Thank you for your video's as they have been a great source of learning both programing and game development as well as clean coding technics. I look forward to continuing to watch and learn, Keep it up your doing Great! (I'm using unity 2022 3d URP project setup and have had no issues after fixing the above Hope this helps!)

Hey, I'm having the problem of needing to save the grid layout, but it can't convert the type array to a class array. How do I save the grid position?

Amazingly good tutorial. Just a question. When you implement the destruction why not just store the vector2 list used when instantiating. On destruction you just access the list from the transform you allready have and delet the object and then clear the transoform. I find the solution you provide much more complicated. So essentially instead of reverse enginering the Vector2 List just Store it.

Thanks for this

I created a system like this for my game except it doesn't use the grid system like that. It basically just rounds the vector coordinates from Camera.ScreenToWorldPoint to full values (1.0f, 2.0f etc) to "snap it" into a grid. I'm also using tilemap colliders to check the area beneath (some buildings can only be constructed on specific ground area and they can't be built on walls or other buildings. I'm also using raycasting to check if the area is a legal building space. I'm about to finish all my sprites for the buildings of my game. Just one more to go, but I had to check this video first to see how you are doing the building placement ':D

Hey, I love this tutorial and definitely could use it in a project in the future. But, I have a suggestion for a future video that could expand upon the grid system. I wonder if there is a way to take the grid and use it to generate terrain and buildings on a map. I’m thinking of a system like ACNH, where an island is a general shape but that the game would randomly generate all the terrain features on a grid inside the blinds if the island so each time you played you got a new island layout (which can be customized if desired later in the game). I’m sure it’s probably a huge ask, but I think it would be a great addition onto the series of grid related tutorials you have.

Hi, thanks for all your content! It helps me a lot - not only with Unity, but also with the "game dev thinking"! :) I have a question related to this. What will be the approach, when the terrain will be not flat? It will be easy to implement the different terrain heights? Thanks for hint :)

@CodeMonkeyUnity

3 жыл бұрын

The simplest approach would be to keep the underlying Grid flat and only snap the placed objects to the terrain. But if you need the Grid to match with the terrain perfectly by area then that's much more complicated, not exactly sure how you could do that, probably need to take the Terrain mesh and make a simplified Grid mesh while keeping the rough terrain shape.

I've seen some comments about it but can't get it working right. In the second, the ghost visual is visible and its transform follows the mouse outside the grid. I need to disable it when outside, and re-enable it when inside the grid. Not sure if the same happens in the video's implementation since the topic isn't covered a lot in it.

To avoid null refs the simple solution is to always validate the position, just a simple check if x,y is > 0,0 and I don't remember how I made it in this demo but yup that's one option, let it follow hte mouse exactly if there's no grid position underneath or leave the ghost on the last valid grid position. Although if you were to use this in a complete game then chances are the play area is much bigger than what I used in the demo so going out of bounds is less of an issue.

Hello CodeMonkey, I followed your tutorial until you placed your first building at around 5:30. It did not work for me as expected, because the building was always placed in the first cell.

You get the grid object on that position, then you can do whatever you want with it.

This is awesome! One question. If I wanted to convert this into a system that would place buildings in random spots on the grid. How would I implement that?

You know the grid width and height, so just do a Random.Range(); to get a random x,z and use that

Hi Code Monkey, you are awesome! You're helping me a lot with your videos! I would like to ask, if I wanted to implement snap in this environment, to be able to move the builded objects, how could I proceed? Maybe did you make a video about it? Thanks in advance!

Snapping how? The system is already snapping to the grid positions

​@@CodeMonkeyUnity I mean, having the possibility of drag existing buildings with mouse and move them on another gridposition instead of destroying them and recreating in the position we want. Also, I wanted to ask how can I check if the building that I want to create is going out of bounds of the grid, handling the exception it throws (NullReferenceException: Object reference not set to an instance of an object). Thank you! I really appreciate your work!

​@@danamarie5655 That's going to depend on how your buildings work. If there's a lot of setup involved then destroying and recreating is the easiest method. In order to move them you need to move the prefab, set up the building again with the new position, and remove/readd on the Grid system. If you know the size of the building you can test if its going outside the bounds or not, if the position is over the width or height then don't move it.

@@CodeMonkeyUnity Thank you for reply! I think I will follow the destroy and recreate method. I would like to destroy the building as you do, then set the placedObjectTypeSO = the building I just destroyed, to have it immediately ready to replace with the visual of that prefab. How can I do this? Obviously I cannot simply do placedObjectTypeSO = placedObject, because they are two different types...

Thanks again for a great video. One thing I would like to understand is how you size your tiles to match with the grid? For example, if I have a path that I am trying to lay out, how are they sized properly for a grid that is larger than the unity unit?

You just scale the visuals/prefabs or modify the grid cellSize to match what you have in the visuals/prefabs

@@CodeMonkeyUnity thanks for the quick reply! Scaling the visuals up led to blurry images but I may just need better images. Also when creating the backgrounds for paths and such it was hard to place them properly without the help of the grid in the scene

@@CodeMonkeyUnity Ah that completely makes sense now that I've had a chance to check it out. Once I added the 2D Tilemap I simply scaled it to match the grid size (10 in my case), and the tiles from the palette naturally lined up without any fuss. Thanks so much! And I purchased your Builder course today too given how helpful you've been! Thanks!

Did you download the project files? That's not a built-in class, it's something I made in a previous video unitycodemonkey.com/search.php?q=grid+system

Ok, so im curious, if im using a 3d environment how do i make each grid tile elevate if say for instance, i have a portion of the map that is higher than the rest of the terrain? im building an isometric 2.5d type game. and i have elevated platforms for hills. also is there a way i could use the terrain data to generate the grid map to follow the terrain? so it procedurally elevates a specific tile according to the map data?

Following the terrain is a bit complex but doable, I made a House System with multiple preset levels kzread.info/dash/bejne/dZiX0Jiue5zNgNI.html

@@CodeMonkeyUnity cool thanks. I checked it out. It uses a list of grids and elevates each grid, switching between them. Seems straight forward enough it should work.

Hi sir, I got error problem in Mouse3D.css in line 22. Its said object reference not set to an instance of an object. where should I put this script to? Thank you

@CodeMonkeyUnity

Just make sure there's an object in the scene with that script unitycodemonkey.com/video.php?v=0jTPKz3ga4w

for some reason when i place a building it only places on the x part of the grid and doesn't go on the z part. this occurred after around 6:30 when implementing the instantiation on the grid and not just anywhere you click

nevermind i found the issue. it was with the gridxz script as i was working from the first video one the playlist making the grid system and when altering the class to the gridz i missed one single ".y" when changing them to lol

I have a question: How would you manage to move a selector based on the mouse position inside the grid AND make the selector move in Y-position when already an object is set on a grid position? I managed to move the selector using the BuildingGhost script but what is your suggestion to make the selector also work in different heights on Y, so you can build up levels on top of each other in 3D?

On my House Building System I just made a clear button input to change which grid is active unitycodemonkey.com/video.php?v=Cdcn6uK9gPo unitycodemonkey.com/video.php?v=gkCBCCKeais If you want something more intuitive you can perhaps do it based on zoom distance or something like that to automatically select which level to build on.
