  1. how setup directx 11 on Code Blocks 17.12? i add the "lib\x86" directory on Global Options-Search Directories-Linker and "include" directory on Global Options-Search Directories-Compiler. but now i get several errors(and warnings) like: " '__in' has not been declared" on "dxgi.h". how can i fix these problems? did i miss something on configurations? i must do another setup?
  2. thank you so much for correct me. i'm sorry, i didn't knew
  3. what i have learned today thank you so much for all... thank you
  4. i understand how add an angle, but not starting and ending angles
  5. thank you so much for all thank you correct me 1 thing: if i use 270 instead 360, we make a open circule or even a curve, right?
  6. - tesselation is how many points we use for draw the circle and that it's the draw quality, right? - i'm sorry, but can you explain better how these math works? float angle = float(i) / float(tesselation) // this goes from 0 to almost 1 * M_PI*2; i'm confused on how you get the angle
  7. theres 2 things: 1 - what value use used on M_PI? 2 - i'm confused: what is tesselation?
  8. vector<Vertex> CirclePoints(float radius) { vector<Vertex> AllPoints; AllPoints.resize(362+361*3); AllPoints[0]= Vertex(0, 0, 0.0f, 1.0f, 0.0f, 0.0f, 0.0f); AllPoints[1] = Vertex(radius, 0, 0.0f, 1.0f, 0.0f, 0.0f, 0.0f); for (float i = 2.0f; i < AllPoints.size(); i=i+0.125f) { AllPoints[(int)i] = Vertex(radius *cos(i), radius *sin(i), 0.0f, 1.0f, 0.0f, 0.0f, 0.0f); } return AllPoints; } finally i get results: now you see why these line: vector<Vertex> AllPoints; AllPoints.resize(362+361*3); but i need more advice, please: how can i make more precision?
  9. for now i only get 2 dots the center and 1 on right i'm sorry but let me ask in a different way(math way): 1 - we have the point A(20,30); 2 - we must rotate the point A by 30º degrees; 3 - how we calculate the point B?
  10. i'm sorry, but i need more help. the zero is the center of window. i have 2 starting dots: 1 - on center (0,0); 2 - on (7,0). now the rest is using the angle=angle-1. and more: i must use radians instead degrees
  11. i'm trying draw a circule using math: class coordenates { public: coordenates(float x=0, float y=0) { X = x; Y = y; } float X; float Y; }; coordenates RotationPoints(coordenates ActualPosition, double angle) { coordenates NewPosition; NewPosition.X = ActualPosition.X*sin(angle) - ActualPosition.Y*sin(angle); NewPosition.Y = ActualPosition.Y*cos(angle) + ActualPosition.X*cos(angle); return NewPosition; } but now i know that these have 1 problem, because i don't use the orign. even so i'm getting problems on how i can rotate the point. these coordinates works between -1 and 1 floating points. can anyone advice more for i create the circule?
  12. i'm trying understand how works the Indices. if the Primtive is D3D11_PRIMITIVE_TOPOLOGY_TRIANGLELIST then 6 Vertex are 2 triangles(and i did that before). the Indices avoid 6 Vertex for 2 triangles... these is what i know. but i don't understand these line: DWORD indices[] = { 0, 1, 2, 0, 2, 3, }; the numbers are the Vertex array\vector elements? can anyone explain more about it?
  13. now i have the answer. my graphics card is for DirectX10... that's why i can inicializate the DirectX 11(it's an update of 10). thank you so much for all
  14. i'm doing my 1st DirectX 11 program: //Cambalinho.h: #include <Windows.h> #include <string> #include <functional> #include <d3d11.h> #include <d3dx11.h> #include <d3dx10.h> #include <DxErr.h> #pragma comment (lib, "d3d11.lib") #pragma comment (lib, "d3dx11.lib") #pragma comment (lib, "d3dx10.lib") #pragma comment (lib, "DxErr.lib") using namespace std;

  15. cambalinho

    i need learn more about the Game Loop

    yah... more big the chapter more big the boring lol honestly a big chapter can be much more tired and much more information\study to 'eat'
