   My blocks aren't disappearing.
  Hello everyone! So after finishing my first game (Pong), I was challenged to make breakout. I have everything set up, but When I get in game the blocks do not disappear. The ball goes right through them, and bounces off the top, and comes back.Here is my struct for blocks.typedef struct{    float x;    float y;    float x2;    float y2;    bool there;} block;Here is the code, in my collision detection to make the blocks disappear.    if(Ball.y2 >= 0.65)    {   for(int y=0; y<5; y++)   {  for(int x=0; x<5; x++)  { if(Ball.y2 >= Blocks[x][y].y && Ball.y2 <= Blocks[x][y].y2 && Ball.x2 >= Blocks[x][y].x && Ball.x <= Blocks[x][y].x2) {Blocks[x][y].there = false; }  }   }    }I have this code to draw to the screen.    for(int y=0; y<5; y++)    {   for(int x=0; x<20; ++x)   {  if(Blocks[x][y].there = true)  { glBegin(GL_QUADS);if(y == 0)    glColor3f(1.0f, 0.0f, 0.0f);if(y == 1)    glColor3f(0.0f, 1.0f, 0.0f);if(y == 2)    glColor3f(0.0f, 0.0f, 1.0f);if(y == 3)   glColor3f(1.0f, 1.0f, 0.0f);if(y == 4)   glColor3f(0.0f, 1.0f, 1.0f);glVertex2f(Blocks[x][y].x, Blocks[x][y].y);glVertex2f(Blocks[x][y].x, Blocks[x][y].y2);glVertex2f(Blocks[x][y].x2, Blocks[x][y].y2);glVertex2f(Blocks[x][y].x2, Blocks[x][y].y); glEnd();  }  else  { glBegin(GL_QUADS);glColor3f(0.0f, 0.0f, 0.0f);glVertex2f(Blocks[x][y].x, Blocks[x][y].y);glVertex2f(Blocks[x][y].x, Blocks[x][y].y2);glVertex2f(Blocks[x][y].x2, Blocks[x][y].y2);glVertex2f(Blocks[x][y].x2, Blocks[x][y].y); glEnd();  }   }    }Can someone tell me what I am doing wrong in this code, that is making my blocks not disappear?   
Quote:if(Blocks[x][y].there = true)This line can very well be the reasonTesting for equality is done with == in C++   ;  Wow--- I must be tired. Thanks =)
