C++ (Cpp) exploded Examples

Example #1

File: tile.cpp Project: oklien/dropdabass

void Tile::explode()
{
    if (m_type == Tile::Stone) {
        setType(Tile::Debris);
        emit exploded();
    } else if (isWalkable()) {
        emit exploded();
    }
}

Example #2

    -1,
    -100,

      // is using a different rounding mode.

  }

  CUDA<float> exploded(N);
