Time for action – moving and resetting

We move the terrain inside the move method.

1. The move method receives as a parameter the amount of movement in the x axis:

   void Terrain::move (float xMove) {
       if (xMove < 0) return;
   
       if (_startTerrain) {
           
           if (xMove > 0 && _gapSize < 5) 
            _increaseGapTimer += xMove;
           
           if (_increaseGapTimer > _increaseGapInterval) {
               _increaseGapTimer = 0;
               _gapSize += 1;
           }
       }
       
       this->setPositionX(this->getPositionX() - xMove);
       
      auto  block = _blocks.at(0);  
      if (_position.x + block->getWidth() < 0) {
         auto firstBlock = _blocks.at(0);
         _blocks.erase(0);
         _blocks.pushBack(firstBlock);
         _position.x +=  block->getWidth();
         
         float width_cnt = this->getWidth() - block->getWidth() - ( _blocks.at(0))->getWidth();
         this->initBlock(block);
         this->addBlocks(width_cnt);
       }
   }
