Using Map Load Hook To Remove Entities

[gamecreator]

I was thinking of using the map load hook to remove rocks in a map and replace them with my own since they need to be interacted with (broken apart). Something like the following:

 

void MapLoadCallback(Entity* entity, Object* extra)

{

std::string text = entity->GetKeyValue("name");

 

if(text.compare("rock")==0)

{

Vec3 pos;

pos=entity->GetPosition();

entity->Release();

 

// Create new breakable rock here at pos

}

}

 

I know people have used this hook to create progress bars and I think Josh said that it wasn't intended for that. So I wonder if this is something that might screw up my program. I haven't tried it yet but before I code it in, I was wondering if this would be ok to do.

 

The other option is to use ForEachEntityInAABBDo and specify the entire map. Not sure if that would be slow.

 

Thoughts or other options?

Your other option is to loop over all the entities in the world after you've loaded the map. world->entities I think is the list you would loop over.

That seems the best way to go. Thanks!
