Tile Transition Logic

How would I go about implementing tile smoothing?

 

Let's say there's a 3x3 set of grass tiles. I want the outside grass tiles to have some kind of outline, while the middle one blends in with the rest.

 

I don't really see a point in sharing any code, as I'm just asking for the implementation process.

 

Thank you to whoever replies!

If you mean an outline as in a dark drawn line, then that would probably be done with composition. Some kind of shader that scales the already rendered image, makes in black and renders the original over it.

 

If you meant a outline as in where a ground tile meets a water tile, those tiles are drawn that way, then linked in a tile set.

I think I've thought of a better way of explaining my question, or what I want to accomplish.

How would I incorporate tile smoothing, so the edges aren't always jagged and pointed. Basically, just corner smoothing.

I think the term you want to search for is auto tiles.  I don't know much about there implementation but I think thats the term used to describe your diagram.

That does seem to be the correct search term, thank you.

Like I said in my original post they are drawn that way:

You don't have to make one for each tile, however it is normal to make a few because then you can fill a full tile zone with them.

The edges are just smaller partial tiles.

      Hello. I am developing a civ 6 clone set in space and I have a few issues. I am using Lua for the logic and UI of the game and c++ directx 12 for the graphics. I need a way to send information between Lua and c++ occasionally and was wondering what is the best and most flexible (and hopefully fast) way to do this. Don't forget that I also need to send things from c++ back to Lua. I know of a lua extension called "LuaBridge" on github but it is a little old and I am worried that it will not work with directx 12. Has anybody done something similar and knows a good method of sending data back and forth? I am aware that Lua is used more and more in the industry and surely plenty of AAA game programmers know the answer to this. I want a good solution that will hopefully still be viable code in a couple of years...

      Hi there.
      I'm pretty new to this and I don't know if it has been asked before, but here I go.
      I'm developing a game using SFML and C++.
      I would like to use the "Tiled" tool to load maps into my game but I don't actually find any tutorial or guide on how to exaclty use it (I know that I have to read an XML file and stuff). I just step into diverse projects that make all a mess. 
      Anyone knows where can I find good information to make my map loader by myself?
      Thanks in advantage!!

      Hello guys,
      I've released my game for the first time. I'm very excited about it and I hope you'll enjoy the game - Beer Ranger. It's a retro-like puzzle-platfromer which makes you think a lot or die trying. You have a squad of skilled dwarfs with special powers and your goal is tasty beer. There is a lot of traps as well as many solutions how to endure them - it is up to your choice how to complete the level! 
      Link to the project: Project site
      Link to the Steam site with video: Beer Ranger
      Have fun and please write feedback if you feel up to.

      So I wrote a programming language called C-Lesh to program games for my game maker Platformisis. It is a scripting language which tiles into the JavaScript game engine via a memory mapper using memory mapped I/O. Currently, I am porting the language as a standalone interpreter to be able to run on the PC and possibly other devices excluding the phone. The interpreter is being written in C++ so for those of you who are C++ fans you can see the different components implemented. Some background of the language and how to program in C-Lesh can be found here:

      As I program this thing I will post code from different components and explain.

      I'm trying to duplicate vertices using std::map to be used in a vertex buffer. I don't get the correct index buffer(myInds) or vertex buffer(myVerts). I can get the index array from FBX but it differs from what I get in the following std::map code. Any help is much appreciated.
      struct FBXVTX { XMFLOAT3 Position; XMFLOAT2 TextureCoord; XMFLOAT3 Normal; }; std::map< FBXVTX, int > myVertsMap; std::vector<FBXVTX> myVerts; std::vector<int> myInds; HRESULT FBXLoader::Open(HWND hWnd, char* Filename, bool UsePositionOnly) { HRESULT hr = S_OK; if (FBXM) { FBXIOS = FbxIOSettings::Create(FBXM, IOSROOT); FBXM->SetIOSettings(FBXIOS); FBXI = FbxImporter::Create(FBXM, ""); if (!(FBXI->Initialize(Filename, -1, FBXIOS))) { hr = E_FAIL; MessageBox(hWnd, (wchar_t*)FBXI->GetStatus().GetErrorString(), TEXT("ALM"), MB_OK); } FBXS = FbxScene::Create(FBXM, "REALMS"); if (!FBXS) { hr = E_FAIL; MessageBox(hWnd, TEXT("Failed to create the scene"), TEXT("ALM"), MB_OK); } if (!(FBXI->Import(FBXS))) { hr = E_FAIL; MessageBox(hWnd, TEXT("Failed to import fbx file content into the scene"), TEXT("ALM"), MB_OK); } FbxAxisSystem OurAxisSystem = FbxAxisSystem::DirectX; FbxAxisSystem SceneAxisSystem = FBXS->GetGlobalSettings().GetAxisSystem(); if(SceneAxisSystem != OurAxisSystem) { FbxAxisSystem::DirectX.ConvertScene(FBXS); } FbxSystemUnit SceneSystemUnit = FBXS->GetGlobalSettings().GetSystemUnit(); if( SceneSystemUnit.GetScaleFactor() != 1.0 ) { FbxSystemUnit::cm.ConvertScene( FBXS ); } if (FBXI) FBXI->Destroy(); FbxNode* MainNode = FBXS->GetRootNode(); int NumKids = MainNode->GetChildCount(); FbxNode* ChildNode = NULL; for (int i=0; i<NumKids; i++) { ChildNode = MainNode->GetChild(i); FbxNodeAttribute* NodeAttribute = ChildNode->GetNodeAttribute(); if (NodeAttribute->GetAttributeType() == FbxNodeAttribute::eMesh) { FbxMesh* Mesh = ChildNode->GetMesh(); if (UsePositionOnly) { NumVertices = Mesh->GetControlPointsCount();//number of vertices MyV = new XMFLOAT3[NumVertices]; for (DWORD j = 0; j < NumVertices; j++) { FbxVector4 Vertex = Mesh->GetControlPointAt(j);//Gets the control point at the specified index.
