Incorporating STL Map into a Scripting Engine for Function Pointer Storage

To enhance the efficiency of your scripting engine, consider leveraging an STL map for managing function pointers. This approach eliminates the need for lengthy conditional statements to invoke specific functions.

For this implementation, begin by declaring your function pointer type as a typedef for readability:

typedef void (*ScriptFunction)(void); // function pointer type

Next, define an unordered_map named script_map with string keys representing function names and ScriptFunction values for the corresponding pointer addresses:

typedef std::unordered_map<:string scriptfunction> script_map;

Example function registration:

void some_function() {}
script_map m;
m.emplace("blah", &some_function);

To call a function, define a call_script function:

void call_script(const std::string& pFunction) {
  auto iter = m.find(pFunction);
  if (iter == m.end()) {
    // function not found
  } else {
    (*iter->second)(); // invoke the function via the pointer
  }
}

Emphasize that you can generalize the ScriptFunction type to std::function* whatever*/> to cater to more than just bare function pointers.
