  1. Thanks for the tips, I'll surely look at that tutorial, now the only thing I still need to figure out is how to make sprites.
  2. Well, It seems that Gamemaker is quite a bit easier, because of it's more simplistic interface, like the creaton of sprites. But I can't yet say it for sure, so after putting some thought it, I'm gonna try unity. Also It's a bit annoying to do things now, because it is like a sauna in my room.   Edit: Well, already discovered my first problem with unity, if I want to drag an image into my project, I won't work.   Edit 2: I've started to try out unity and one feature I really like, which Gamemaker has is the ability to change values without having to edit the code and thinking of it, I'll have to use unity next year for school, so I think I'll pick Unity, unlike I said in my previous post.
  3. I've looked on the internet some more and I think I'll go with game maker studio for now and if I wan't it would be that 'hard' to port it to unity if I would want to. EDIT: (for now)
  4. Well, I've tried out game maker already and it uses it's own language, called GML, which they say is based on C. C# would be that hard for me, because I already know c++, so I'll probably just need to learn the differences between those 2.   EDIT: accidentally typed c# instead of c++, if you wonder where the comment below comes from
  5. I would like to make a roquelike game, I've tried programming an engine myself, but I would prefer an engine. I've looked at both Game Maker: Studio and Unity 2d and to be honest, I'm not sure which would be better.   Does anyone have experience with them or know which on would be the best?
  6. I've tried using sdl, but than I remembered I could also do it with sfml last night, in which I have a bit more experience and for me, it seems a bit easier.
  7. Thanks for the replies, in the meantime I've also been searching some more on the internet and it seems that newer version of dwarf fortress which can be run on linux seem to use SDL, so I'll look into SDL, which also would give me a system to handle input more easily, because I was planning to use getch, but it is a bit annoying when it comes to arrow keys and things like that.
  8. I've been interesting in making something in the style of dwarf fortress, so I want to find a way to change the fore and background color of individual characters. I'm on Windows, so I've looked at SetConsoleTextAttribute(), but It is very limited in color and I'd prefer having a way of changing the colors using rgb values.   Seeing that I'vs tried SetConsoleTextAttribute(), so It's no problem even if it is a platform specific way.   If you know a way to do it, please let me know.
  9. DX12 [Solved][D3D11] D3D not presenting

    Yes, that was my problem.   I've just used AdjustWindowRect() during the creation of my window and now it works.   Thank you very much.
  10. So after some people telling me it would be better do start with dx11, before dx12, I decided to do it, but now I have a problem I've hadn't had before: dx11 is not presenting anything to the screen.

  11. Ok, I'll be sure to do that. I've looked on my computer that I once started with dx11, but never really continued, so I'm going to do that and if I have something nice, I can always port it later. I'll start with dx11 and than I'm also going to have a head start for next school year.   Thanks for the info.
  12. I've actually already programmed with opengl, it's just that I didn't think of when I was typing that, because it has already been a few months since I did that.    And the reason I chose to learn some D3D12, is because I like to make it challenging to myself, also, I have lot of free time now, so I'm taking it slow, school only starts in the last week of september.
  13. OK, I've added that code and I get this:   D3D12 ERROR: ID3D12GraphicsCommandList::*: This API cannot be called on a closed command list. [ EXECUTION ERROR #547: COMMAND_LIST_CLOSED]   Because I'm new when it comes to graphics programming, I'm not sure where my problem is.   EDIT: after looking at the the tutorial code once again, I found the problem, in the tutorial source code, a close call was removed, but they did not tell that in the tutorial, but I'm extremely thankful for the help, MJP. Especially because after the vacation, my second year game development will start and then we will only start with graphics programming, so I wanted to be a bit ahead.
  14. I've been following this tutorial: http://www.braynzarsoft.net/viewtutorial/q16390-04-direct3d-12-drawing But now I've run into an annoying problem, it doesn't render and I've check the graphics debug, like it said in the tutorial and the vertex data isn't given to the gpu. it says that the type is byte2x, but it is a float, and the data it has is 00000000.   If you can help me, thanks.   code:   Renderer.h [spoiler] #pragma once   #include "Helpers\Util.h"   namespace VEH { class Window; }   namespace VE { class Renderer { public: Renderer(VEH::Window* outputWindow); ~Renderer();   bool Init(); //initialize d3d12 void Tick(); // update game logic void TickPipeline(); // update d3d pipeline (update command list) void Draw(); // execute command list void Shutdown(); //release objects and clean up memory void WaitForPreviousFrame(); // wait until gpu is finished with the command list   private:   const static int m_FrameBufferCount = 3; //number of buffers we want, 2 for double buffering, 3 for tripple buffering   ID3D12Device* m_pDevice = nullptr; // direct3d device IDXGISwapChain3* m_pSwapChain = nullptr; // swapchain used to switch render targets ID3D12CommandQueue* m_pCommandQueue = nullptr; // container for command lists ID3D12DescriptorHeap* m_pRtvDescriptorHeap = nullptr; // a descriptor heap to hold resources like render targets ID3D12Resource* m_paRenderTargets[m_FrameBufferCount] = {}; // number of render targets equal to the buffer count ID3D12CommandAllocator* m_paCommandAllocator[m_FrameBufferCount] = {}; // we want enough allocatorsfor each buffer * number of threads (only 1 thread for now) ID3D12GraphicsCommandList* m_pCommandList = nullptr; // a command list we can record commands into, the execute them to render the frame ID3D12Fence* m_paFence[m_FrameBufferCount] = {}; // an object that is locked while our command list is being executed by the gpu.

  15. OpenGL opengl texture problem

    Oh, so you can't give the vertices to draw using elements and the texture coords separately. and If I use separate vertices, isn't it going to be laggy?
