Number of entities stored in a map (C++)

[george68]

Hi,

Is there any way to get the number of entities they are stored in a map file.

I know that I can iterate through all the entities using the hook function, but I was wondering If I can get the number of entities without iteration

If you are using C++, there is a vector containing all the entities in the World class. You can get the size of that.

If you are using lua, I'd make a new variable and increment it with the map hook.

There should be a World->CountEntities() now that I think of it. You can also check the Menu.lua script as that iterates through all the entities without a Map hook to find a camera. It should use the CountEntities() function.

Sorry about that.

I'll take a look.

Thank you very much!

I’m curious what you will use this for?

For maps with large number of entities, it would be nice if I can display a progress of loading. So, I need this information.

So far I don't now how to get the number of entities in the map, without load it first.
