General question

I'm developing a first person shotter. Which do you think is the best way to implement a crosshair associated to the viewpoint?

Thank you very much!

The way I have done this is simply go into landscape 2d(for landscape games) and then draw four lines. here is the code, just remember to go into landscape 2d(see tutorials if you don't know how to do this)

Code:

glPushMatrix();
   {
      glTranslatef( sio2->_SIO2window->scl->x * 0.5f,
                sio2->_SIO2window->scl->y * 0.5f, 0.0f );
      sio2MaterialReset();
      glColor4f(1, 1, 0, 1);
      glLineWidth(1);
      glEnableClientState(GL_VERTEX_ARRAY);
      
      float drawArray[4] = {-35, 0, -10, 0};
      glVertexPointer(2, GL_FLOAT, 0, drawArray);
      glDrawArrays(GL_LINES, 0, 2);
      
      float drawArray2[4] = {0, -35, 0, -10};
      glVertexPointer(2, GL_FLOAT, 0, drawArray2);
      glDrawArrays(GL_LINES, 0, 2);
      
      float drawArray3[4] = {35, 0, 10, 0};
      glVertexPointer(2, GL_FLOAT, 0, drawArray3);
      glDrawArrays(GL_LINES, 0, 2);
      
      float drawArray4[4] = {0, 35, 0, 10};
      glVertexPointer(2, GL_FLOAT, 0, drawArray4);
      glDrawArrays(GL_LINES, 0, 2);
   }
   glPopMatrix();

hope this helps

Thank you!!!

Simple solutions are the best
