Now say you have defined and declared some vector A and you want to copy the content of A into another vector B. The whole point of this is to fill listEnvironmentStatic with game object and when the game map starts, everything gets copied to listEnvironment for simulations and when the players wants to reset the map, listEnvironment copies everything from listEnvironmentStatic once again and every object is back to its original location. That makes no sense unless you explain it. Certificates
That's why segmentation fault and we need to allocate memory, rather say define the vector along with its elements. That means only the element object references are copied, not the actual objects. When dealing with a drought or a bushfire, is a million tons of water overkill?

Now say you have defined and declared some vector A and you want to copy the content of A into another vector B. The whole point of this is to fill listEnvironmentStatic with game object and when the game map starts, everything gets copied to listEnvironment for simulations and when the players wants to reset the map, listEnvironment copies everything from listEnvironmentStatic once again and every object is back to its original location. That makes no sense unless you explain it. Certificates
That's why segmentation fault and we need to allocate memory, rather say define the vector along with its elements. That means only the element object references are copied, not the actual objects. When dealing with a drought or a bushfire, is a million tons of water overkill?
