  1. OpenGL OpenGL game development - chris sheddon

    The link wordware.com/files/openglgd is redirecting to http://www.jblearning.com/ . But the book OpenGL game development is not present in their entire list . can anyone give the link in the web where the source is available.
  2. OpenGL Bloxorz game in OpenGL.

    hello , Thanks dpadam450 for the answer. I have some how managed to draw the floor and a block on it. by taking two functions like this : drawFloor present in Floor class outside main : void Floor::drawFloor() { glRotatef(45.5f,1.0f,1.0f,0.0f); //Draw floor for(int i = 1;i<6;i++) { for(int j = 1;j<6;j++) { //For hole to appear at 3,3 if(i == 3 && j==3) { glTranslatef(1.0f,0.0f,0.0f); continue; } glBegin(GL_QUADS); // Top Face glColor3f(1.0f,0.0f,0.0f); glTexCoord2f(0.0f, 1.0f); glVertex3f(-0.500f,0.500f,-0.500f); //top left glTexCoord2f(0.0f, 0.0f); glVertex3f(-0.500f,0.500f,0.500f); //bottom left glTexCoord2f(1.0f, 0.0f); glVertex3f( 0.500f,0.50f,0.50f); //bottom right glTexCoord2f(1.0f, 1.0f); glVertex3f( 0.50f,0.50f,-0.50f);//top right //Left Face glTexCoord2f(0.0f, 0.0f); glVertex3f(-0.50f, 0.50f, -0.50f); //Top front glTexCoord2f(1.0f, 0.0f); glVertex3f(-0.50f, 0.30f, -0.50f); glTexCoord2f(1.0f, 1.0f); glVertex3f(-0.50f, 0.30f, 0.50f); glTexCoord2f(0.0f, 1.0f); glVertex3f(-0.50f, 0.50f, 0.50f); // Front Face glTexCoord2f(0.0f, 0.0f); glVertex3f(0.50f,0.50f, 0.50f); //top right glTexCoord2f(1.0f, 0.0f); glVertex3f(-0.50f,0.50f,0.50f); // top left glTexCoord2f(1.0f, 1.0f); glVertex3f(-0.50f,0.30f, 0.50f); //bottom left glTexCoord2f(0.0f, 1.0f); glVertex3f(0.50f,0.30f, 0.50f); //bottom right // Bottom Face glTexCoord2f(1.0f, 1.0f); glVertex3f( 0.50f,0.30f,0.50f); // top right glTexCoord2f(0.0f, 1.0f); glVertex3f(-0.50f,0.30f,0.50f); // top left glTexCoord2f(0.0f, 0.0f); glVertex3f(-0.50f,0.30f,-0.50f); // bottom left glTexCoord2f(1.0f, 0.0f); glVertex3f( 0.50f,0.30f, -0.50f); //bottom right // Back Face glTexCoord2f(1.0f, 0.0f); glVertex3f(-0.50f,0.50f,-0.50f); // top left glTexCoord2f(1.0f, 1.0f); glVertex3f(0.50f, 0.50f,-0.50f); //top right glTexCoord2f(0.0f, 1.0f); glVertex3f( 0.50f, 0.30f,-0.50f); //bottom right glTexCoord2f(0.0f, 0.0f); glVertex3f( -0.50f,0.30f, -0.50f);//bottom left // Right face glTexCoord2f(1.0f, 0.0f); glVertex3f( 0.50f, 0.50f, -0.50f); // Top right glTexCoord2f(1.0f, 1.0f); glVertex3f( 0.50f, 0.50f, 0.50f); // top left glTexCoord2f(0.0f, 1.0f); glVertex3f( 0.50f, 0.30f, 0.50f); //bottom right glTexCoord2f(0.0f, 0.0f); glVertex3f( 0.50f, 0.30f, -0.50f); //bottom left glEnd(); glTranslatef(1.0f,0.0f,0.0f); } glTranslatef(-5.0f,0.0f,-1.0f); } drawCube present in Cube class : void Cube::drawCube() { glBegin(GL_QUADS); // Top Face glColor3f(0.0f,1.0f,0.0f); glTexCoord2f(0.0f, 1.0f); glVertex3f(-0.500f,0.500f,-0.500f); //top left glTexCoord2f(0.0f, 0.0f); glVertex3f(-0.500f,0.500f,0.500f); //bottom left glTexCoord2f(1.0f, 0.0f); glVertex3f( 0.500f,0.50f,0.50f); //bottom right glTexCoord2f(1.0f, 1.0f); glVertex3f( 0.50f,0.50f,-0.50f);//top right //Left Face glTexCoord2f(0.0f, 0.0f); glVertex3f(-0.50f, 0.50f, -0.50f); //Top right glTexCoord2f(1.0f, 0.0f); glVertex3f(-0.50f,-0.5f, -0.50f); //top left glTexCoord2f(1.0f, 1.0f); glVertex3f(-0.50f,-0.5f, 0.50f); //bottom left glTexCoord2f(0.0f, 1.0f); glVertex3f(-0.50f, 0.50f, 0.50f); //bottom right // Front Face glTexCoord2f(0.0f, 0.0f); glVertex3f(0.50f,0.50f, 0.50f); //top right glTexCoord2f(1.0f, 0.0f); glVertex3f(-0.50f,0.50f,0.50f); // top left glTexCoord2f(1.0f, 1.0f); glVertex3f(-0.50f,-0.5f, 0.50f); //bottom left glTexCoord2f(0.0f, 1.0f); glVertex3f(0.50f,-0.5f, 0.5f); //bottom right // Bottom Face glTexCoord2f(1.0f, 1.0f); glVertex3f( 0.50f,-0.50f,0.50f); // top right glTexCoord2f(0.0f, 1.0f); glVertex3f(-0.50f,-0.50f,0.50f); // top left glTexCoord2f(0.0f, 0.0f); glVertex3f(-0.50f,-0.50f,-0.50f); // bottom left glTexCoord2f(1.0f, 0.0f); glVertex3f( 0.50f,-0.50f, -0.50f); //bottom right // Back Face glTexCoord2f(1.0f, 0.0f); glVertex3f(-0.50f,0.50f,-0.50f); // top left glTexCoord2f(1.0f, 1.0f); glVertex3f(0.50f, 0.50f,-0.50f); //top right glTexCoord2f(0.0f, 1.0f); glVertex3f( 0.50f,-0.50f,-0.50f); //bottom right glTexCoord2f(0.0f, 0.0f); glVertex3f( -0.50f,-0.50f, -0.50f);//bottom left // Right face glTexCoord2f(1.0f, 0.0f); glVertex3f( 0.50f, 0.50f, -0.50f); // Top left glTexCoord2f(1.0f, 1.0f); glVertex3f( 0.50f, 0.50f, 0.50f); // bottom left glTexCoord2f(0.0f, 1.0f); glVertex3f( 0.50f, -0.50f, 0.50f); //bottom right glTexCoord2f(0.0f, 0.0f); glVertex3f( 0.50f, -0.5f, -0.50f); //top right glEnd(); } I have placed the hole at 3,3 position look on drawing floor. My main problem is moving the block left and right . For that I have taken a structure called typedef struct { public: float x_pos; float y_pos; float z_pos; float radian; }cube_param; I created an object like cube_param cube_pos; while left key is pressed : case WM_KEYDOWN: // Is A Key Being Held Down? { keys[wParam] = TRUE; // If So, Mark It As TRUE switch(wParam) { case VK_LEFT: { cube_pos.x_pos = - 1.0f ; cube_pos.y_pos = -1.0f; cube_pos.z_pos = 0.0f; cube_pos.radian = -90.0f; cube->drawCube(cube_pos); } } return 0; } where drawCube(cube_pos); contains the same code as drawCube() but it has to move it. Here does the structure cube_pos goes away with values to drawCube(cube_param cube_pos) Look at it : // For movement of cube void Cube::drawCube(cube_param cube_pos) { float x_pos = cube_pos.x_pos; float y_pos = cube_pos.y_pos; float z_pos = cube_pos.z_pos; float radian = cube_pos.radian; //glTranslatef(1.0f,1.0f,0.0f); glRotatef(radian,x_pos,0.0f,0.0f); glBegin(GL_QUADS); // Top Face glColor3f(0.0f,1.0f,0.0f); glTexCoord2f(0.0f, 1.0f); glVertex3f(-0.5f + x_pos,0.5f + y_pos,-0.5f); //top left glTexCoord2f(0.0f, 0.0f); glVertex3f(-0.5f + x_pos,0.5f + y_pos,0.5f); //bottom left glTexCoord2f(1.0f, 0.0f); glVertex3f( 0.5f + x_pos,0.5f + y_pos,0.5f); //bottom right glTexCoord2f(1.0f, 1.0f); glVertex3f( 0.5f + x_pos,0.5f + y_pos,-0.5f);//top right //Left Face glTexCoord2f(0.0f, 0.0f); glVertex3f(-0.50f, 0.50f, -0.50f); //Top right glTexCoord2f(1.0f, 0.0f); glVertex3f(-0.50f,-0.5f, -0.50f); //top left glTexCoord2f(1.0f, 1.0f); glVertex3f(-0.50f,-0.5f, 0.50f); //bottom left glTexCoord2f(0.0f, 1.0f); glVertex3f(-0.50f, 0.50f, 0.50f); //bottom right // Front Face glTexCoord2f(0.0f, 0.0f); glVertex3f(0.50f,0.50f, 0.50f); //top right glTexCoord2f(1.0f, 0.0f); glVertex3f(-0.50f,0.50f,0.50f); // top left glTexCoord2f(1.0f, 1.0f); glVertex3f(-0.50f,-0.5f, 0.50f); //bottom left glTexCoord2f(0.0f, 1.0f); glVertex3f(0.50f,-0.5f, 0.5f); //bottom right // Bottom Face glTexCoord2f(1.0f, 1.0f); glVertex3f( 0.50f,-0.50f,0.50f); // top right glTexCoord2f(0.0f, 1.0f); glVertex3f(-0.50f,-0.50f,0.50f); // top left glTexCoord2f(0.0f, 0.0f); glVertex3f(-0.50f,-0.50f,-0.50f); // bottom left glTexCoord2f(1.0f, 0.0f); glVertex3f( 0.50f,-0.50f, -0.50f); //bottom right // Back Face glTexCoord2f(1.0f, 0.0f); glVertex3f(-0.50f,0.50f,-0.50f); // top left glTexCoord2f(1.0f, 1.0f); glVertex3f(0.50f, 0.50f,-0.50f); //top right glTexCoord2f(0.0f, 1.0f); glVertex3f( 0.50f,-0.50f,-0.50f); //bottom right glTexCoord2f(0.0f, 0.0f); glVertex3f( -0.50f,-0.50f, -0.50f);//bottom left // Right face glTexCoord2f(1.0f, 0.0f); glVertex3f( 0.50f, 0.50f, -0.50f); // Top left glTexCoord2f(1.0f, 1.0f); glVertex3f( 0.50f, 0.50f, 0.50f); // bottom left glTexCoord2f(0.0f, 1.0f); glVertex3f( 0.50f, -0.50f, 0.50f); //bottom right glTexCoord2f(0.0f, 0.0f); glVertex3f( 0.50f, -0.5f, -0.50f); //top right glEnd(); } My idea is when left key is pressed i want to translate each and every vertex by adding or subtracting the x_pos,y_pos,z_pos present in cube_param structure and then translate and rotate it. will it ultimately work for each and every move ? If so how to do it.
  3. OpenGL Bloxorz game in OpenGL.

    Hi , I want to design the floor of the bloxorz game in photoshop. is it a good idea to design the entire floor as one bmp file and load it ? If so I don't know how to create this floor in photoshop. can anyone please guide me?
  4. OpenGL Bloxorz game in OpenGL.

    The http://nehe.gamedev.net/ . Yes I have seen them. Do you mean the Legacy Tutorials? I think these are very old like in 2000 . Will it be still useful for beginners in OpenGL to follow them?
  5. Hi friends, I am trying to develop the Bloxorz game in OpenGL. Please see this link http://www.albinoblacksheep.com/games/bloxorz To do that I have draw the squares floor and a rectangle on top of it. By I have trouble starting this. I mean I can't figure out how can I draw the floor like in 3d and a rectangular cube thing. Please guide me. I have googled this item , but haven't got anything.
  6. Hello, I am making a galaxian game in sdl . (For quick watch of galaxians who doesn't know it http://www.1980-games.com/us/old-games/java-games/galaxian.php ) I have drawn the aliens ,ship and bullet . The ship is moving is moving left and right . The bullet is moving up for shooting the aliens. I want to know how to make a new bullet appear after one is gone. How to move the bullet along with the ship. Also i didn't provide any kind of animation for the aliens .How to do it. I didn't use any opengl purely sdl and c++. If i use any opengl is there any benefit for me or I can go with sdl itself? I don't know how to redraw the bullet. Please see here this is my main.cpp that handles the key Events and drawing : #include "SDLGameEngine/cGraphics.h" #include "SDLGameEngine/Defines.h" #include "SDLGameEngine/cInput.h" #include "cGreenAlien.h" #include "cShip.h" #include "SDLGameEngine/Math.h" #include "cBullet.h" //collision detection with screen ends bool shipCanMoveLeft(); bool shipCanMoveRight(); cShip ship; cBullet bullet; int main(int argc,char **argv) { cGraphics* graphics = new cGraphics(WINDOW_WIDTH,WINDOW_HEIGHT,"Galaxians Clone"); SDL_Surface* bitmap = graphics->LoadImage("Data/alien2.bmp"); cInput input = cInput(); //Green Alien cGreenAlien greenalien1 = cGreenAlien(graphics,bitmap,100.0f,210.0f,5,9,28, 20,BIGBUG_SPEED); cGreenAlien greenalien2 = cGreenAlien(graphics,bitmap,140.0f,210.0f,5,9,28, 20,BIGBUG_SPEED); cGreenAlien greenalien3 = cGreenAlien(graphics,bitmap,180.0f,210.0f,5,9,28, 20,BIGBUG_SPEED); cGreenAlien greenalien4 = cGreenAlien(graphics,bitmap,220.0f,210.0f,5,9,28, 20,BIGBUG_SPEED); cGreenAlien greenalien5 = cGreenAlien(graphics,bitmap,260.0f,210.0f,5,9,28, 20,BIGBUG_SPEED); cGreenAlien greenalien6 = cGreenAlien(graphics,bitmap,300.0f,210.0f,5,9,28, 20,BIGBUG_SPEED); cGreenAlien greenalien7 = cGreenAlien(graphics,bitmap,340.0f,210.0f,5,9,28, 20,BIGBUG_SPEED); cGreenAlien greenalien8 = cGreenAlien(graphics,bitmap,380.0f,210.0f,5,9,28, 20,BIGBUG_SPEED); cGreenAlien greenalien9 = cGreenAlien(graphics,bitmap,420.0f,210.0f,5,9,28, 20,BIGBUG_SPEED); cGreenAlien greenalien10 = cGreenAlien(graphics,bitmap,460.0f,210.0f,5,9,28, 20,BIGBUG_SPEED); ship = cShip(graphics,bitmap,SHIP_START_X,SHIP_START_Y,SHIP_IMG_X,SHIP_IMG_Y,SHIP_WIDTH,SHIP_HEIGHT,SHIP_SPEED); bullet = cBullet(graphics,bitmap,BULLET_START_X,BULLET_START_Y,BULLET_IMG_X,BULLET_IMG_y, BULLET_WIDTH,BULLET_HEIGHT,1.0f); bool quit = false; while(quit == false) { if(input.GetEvent()) { if(input.IsQuit()) { quit = true; } switch(input.GetKeyPressed()) { case SDLK_ESCAPE: { quit = true; } break; case SDLK_SPACE: { bullet.pushUp(); } break; } } if(input.KeyHeld(SDLK_LEFT)) { if(shipCanMoveLeft()) { ship.moveLeft(); } } if(input.KeyHeld(SDLK_RIGHT)) { if(shipCanMoveRight()) { ship.moveRight(); } } bullet.MoveVertical(); graphics->ClearScreen(0,0,0); greenalien1.Draw(); greenalien2.Draw(); greenalien3.Draw(); greenalien4.Draw(); greenalien5.Draw(); greenalien6.Draw(); greenalien7.Draw(); greenalien8.Draw(); greenalien9.Draw(); greenalien10.Draw(); ship.Draw(); bullet.Draw(); graphics->Show(); } graphics->CloseImage(bitmap); delete graphics; return 0; } //collision detction of ship with left screen bool shipCanMoveLeft() { SDL_Rect rect = ship.AfterMoveLeft(); // check left extremity if(rect.x < 0) { return false; } return true; } bool shipCanMoveRight() { SDL_Rect rect = ship.AfterMoveRight(); if((rect.x + SHIP_WIDTH) > WINDOW_WIDTH) { return false; } return true; }
  7. Hello, I am a beginner in game programming in sdl. I am following aaron cox's tutorial's at http://www.aaroncox.net/tutorials/ He has given an sdlGameEngine and using it he has explained how to deal with game basics. Everything has worked fine but collision detection is not working. I have included all the source code of the msvc project. The controls to move bigbug are the arrow keys and to move the smallbug are asdw . The bugs should stop while colliding with screen and rock. Thanks in advance.

  9. Hello Gamedev.net , I am a 23 year old graduate in Information Technology from India. I have recently started doing programming and I want to choose a career in computer games. so I have joined in a start up company with four members and learning programming and graphics on my own from ebooks and net tutorials. Is the thing which I am doing is correct? can anyone do this alone? Because there are no trainers here I am alone learning the whole day searching over the internet for tutorials on programming.A group of three people who actually work in other companies come in the weekends and work in my company have worked a small letter project for children on IPAD that enables to learn the letter by tracing them. I am not into any project but he may put into after some days.Till now he said me practice some c++,data structures and opengl stuff. waiting for your reply.
