Please reorder your Grid System in Unity playlist this should be 3rd, not 2nd part because you use and modify code from the heatmap video and it is super confusing. I almost rewatched full grid video to search what I missed but then I noticed that the heatmap video upload date is between this and first one so after heatmap video it makes so much more sense.

Amazing content! Thank you very much!

Being able to use any type is fantastic

Excellent contents! Thank you!

Excellent presentation of Lambda use, when you havent done it in a while its a great refresher

Great tutorial! Thanks man! I would change just one thing on your implementation. Your HeatMapGridObject shouldn't hold a reference to the grid since you are creating an unneeded cross-reference plus the need of adding all those parameters to the constructor. What I would do is have the HeatMapGridObject raise an event whenever it is modified, and whoever knows that GridObject can subscribe to that event, in our case, your Grid. So, the Grid, when creating all its objects, it also registers to the event and handles it in whatever way it desires. It's a very simple change but I believe it enforces better encapsulation and simplifies the construction.

@CodeMonkeyUnity

Yup that is indeed another approach and actually what I use in the Grid System that I've used in my games for several years now. I tried to keep the video simple so I figured having the object contact the grid would be easier to follow than events.

This is not possible if you want the grid to be generic. It would need to know about specific types to subscribe to their OnChanged event. Other than creating a big type casting mess, which creates lots of dependencies, there is no other way than what is shown in the video, but I'd be happy to be proven wrong!

So the issue with the HeatMapVisual file getting errors is that the Grid class has the same name as a built-in Unity class. So as soon as it was changed to generics, the HeatMapVisual script started referencing the Unity class instead of the Grid class we created. Comment that script out until you hit the part in the vid where it gets fixed.

Hello, thanks for yet another great video, awesome pace, awesome concepts. I have a question, at minute 16 you implement a bunch of code to trigger the grid update, creating also a cross dependency between the grid and the object. Isn't it easier if you just call the set function from the testing script? // I use a dictionary for the grid cells) if (Input.GetMouseButtonDown(0) && index >= 0) { HeatMapObject heatMapObject = myGrid.GetGridObject(index); if (heatMapObject != null) { heatMapObject.AddValue(cellValueStep); myGrid.SetGridObject(index, heatMapObject); } }

You don't need to make the heat map or the tilemap to learn how it works, but watching those videos will give you more ideas for various use cases.

Super video, very clear and which shows the interest of the generics. I'm just pointing out that the normalized value is incorrect, because it ignores the minimum value: (value - min) / (max - min).

I figured using your grid would be the best solution, as I can draw easily and add custom values to it, (for comparing afterwards).

It is a bit confusing at first but when it clicks it all makes sense. Go slowly step by step and play around with the code. First try to make a simple untextured polygon. So manually position 3 vertices and 3 triangles. Then play around with the vertices to see the polygon change and play around with the triangles to see how if you put them counter clockwise the mesh will be facing backwards. Once you understand how a simple triangle works you know everything you need to expand upon it. A quad is just two triangles merged together.

@@CodeMonkeyUnity Same problem as @Silent Sam Plays. I've followed everything to a T and still no success. The only way I could ever get it to work was to create a 2nd grid script specifically for the color changing based on the heatmap but with debugging turned off. Then in the testing script create the 2nd grid in the same exact position with exactly the same dimensions and specs. Instead of calling SetValue from the Grid class in the grid script. I had to call AddValue from the Grid class created with the heatmap video(The 2nd grid script specifically for color changing). Is this the way you made it work? //Variables [SerializeField] private HeatMapVisual heatMapVisual; [SerializeField] private HeatMapBoolVisual heatMapBoolVisual; private Grid grid; private Grid gridBool; // Start is called before the first frame update void Start() { grid = new Grid(20, 10, 15f, Vector3.zero); gridBool = new Grid(20, 10, 15f, Vector3.zero); heatMapVisual.SetGrid(grid); heatMapBoolVisual.SetGrid(gridBool); } // Update is called once per frame void Update() { if (Input.GetMouseButtonDown(0)) { Vector3 position = UtilsClass.GetMouseWorldPosition(); grid.AddValue(position, 100, 100, 1); gridBool.SetValue(position, true); } } From the video it doesn't show this yet yours still works as intended by changing not only to True but also to green. However in the video you do disable the original HeatMapVisual GameObject. Whenever I do this mine surely doesn't work. The only way I get the same results as you at this point is by doing what I stated. Was this just a cheeky work around that I did? Is my thinking completely off? Any replies are greatly appreciated.

Instead of creating a reference to the grid in the HeatMapObject, i did this: if (gridTestObject != null) { { gridTestObject.AddValue(5); grid.SetGridObject(gridTestObject.x, gridTestObject.y, gridTestObject); } } This works, but is this a valid solution?

Sure, but what exactly are you doing? It seems like you're not creating all the grid objects during construction but rather only when setting the value.

Hi, around the 17 minute mark where you change the grid type from bool to HeatMapGridObject I start getting errors. My grid was working perfectly up until then with the bool type, but when I try to switch to the HeatMapGridObject Grid I get a namespace error; CS0246 The type or namespace name 'HeatMapGridObject' could not be found (are you missing a using directive or an assembly reference?) I have no idea what to do about this or how to fix it. I'm completely stumped. I have noticed that HeatMaprGridObject also exists in the Testing Class, but am unsure if that affects anything as in your video you didn't change them (or show you changing them). The only things I did differently to you in the video is not rename all of the "GetValue"s, would that change anything? I also commented out the entirety of the first heatmap and bool scripts as they were causing clashes and were no longer being used as far as I could tell.

I did this one very different due to removing grid Events + LateUpdate from heatmap for performance. Even a constant bool check indefinitely isn't good in an update. I've learned a long time ago to avoid putting things in Update threads. That is how you achieve prime optimization. This is the main part that matters to show how to avoid this. You could technically still use an event for this part and just don't use the lateupdate for the other part I mentioned in the heatmap video. Either way, nothing in updates unless it's input logic. Even then, it would probably be better to use the new input system Unity created for this very reason. public void TriggerGridObjectChanged(int x, int y) { SetValue(x, y, gridArray[x, y]); } public HeatMapGridObject(Grid3D grid, int x, int y, HeatMapGenericVisual hmgv) { this.grid = grid; this.x = x; this.y = y; this.hmgv = hmgv; } public void AddValue(int addValue) { value = Mathf.Clamp(value + addValue, MIN, MAX); grid.TriggerGridObjectChanged(x, y); hmgv.UpdateHeatMapVisualGeneric(); }

You have magic code in the video that is never revealed as to its addition to the grid.cs. At 6:04 is the line. "debugTextArray[x, y] = UtilsClass.CreateWorldText(gridArray[x, y]?.ToString(), null, GetWorldPosition(x, y) + new Vector3(cellSize" is all we can see but the creation of that line is never shown in any of the videos in the creation of that script. Therefore, how can the audience know what the end of that line is? As there is no link to say "Find out how to remove the error message by typing in the actual code".

The Grid can represent anything you want. Use it to represent a Ground tile, add the logic to destroy it as well as build it and you have Terraria.

@@CodeMonkeyUnity I got that far but how to procedural generate all the tiles on the grids and do i generate new grids as chunks?

Ffs, why use stuff from other tutorials such as heatmap that you didn't show to implement in the first one. :/

Because this wasn't planned ahead of time, I just built interesting systems and kept building upon it. If you're looking for a guided step-by-step then look into my TBS course where I do use a Grid System and build it all step-by-step unitycodemonkey.com/courses.php?c=turnbasedstrategy

@@CodeMonkeyUnity Understandable, but still feels there should be some guidance ( I know " oh just go look for it " ), but at the same time it makes me leave the channel and I do like your content most of the time, but its just feels more of a dev-log than how to do it, but that is understandable you never called it a tutorial. Just think overall I'd make videos first utilize the content in the code you are making and then later in the video it could be added to utlities I may be wrong of course! (Considering my videos are nothing of good either I cannot tell you how to do it).

Pleaseee, don't use speeding up. Its so confusing when you can't understand what's going on and when code part is huge I get lost with your tutorial.

You can pause the video at any time and download the completed Project files from the website.

@@CodeMonkeyUnity Its a good thing that you do, keep the tempo high for when you just want the explanation of the code, but don't the specifics, as you say, can always download or pause to see it.

I got confused in these fucking videos what comes after?
