LW 2.5, C++, parsing a scene for an entity or multiple entities.

[Pastaspace]

Couldn't find a good topic on this, so I'm gonna ask myself.

Say I have a scene that I've loaded, and inside the scene I want to retrieve all of the entities of a specific type (like say, I want to get all the oil barrels for my barrel-romance simulator).

The problem is, I can't find a place to start. How would I implement a function where I could parse a scene for all of a type of entity?

Doesn't 2.5 return a root entity the entire scene is parented to? So you would just iterate through the children.

[Pastaspace]

That would be the entity returned by LoadScene() correct?

You can use that. This is an example.

 

e is of type TEntity

en is a string

 

scene = LoadScene("abstract::myscene.sbx");
childCount = CountChildren(scene);
for(i=1;i<=childCount;i++)
{
e=GetChild(scene,i);
en=GetEntityKey(e,"name");
...
