Find entity in world (After using Map::Load)

[jamesmintram]

Hi,

 

I am trying to work out the best way for me to find an entity in the world after using Map::Load.

 

I have an entity I have positioned in the Leadwerks editor with the name "SkyBox", after calling Map::Load what is the best way to retrieve this entity (in C++)

 

Regards,

James

You have some example here :

Or try the code klepto posted here:

http://www.leadwerks.com/werkspace/topic/6959-map-loading/#entry57032

 

haven't tried that myself but when there is already a list in world->entities it should work.

Note that I'm not sure if world.entities works in Lua. I seem to recall hearing that it didn't.

[beo6]

since he wrote

(in C++)

 

it shouldn't be a problem. But good hint anyway.

[Rick]

My bad. Missed that

Thanks for the replys guys!

 

I went with:

 

Entity *EntityByName (std::string name)
{

for ( int t = 0; t < world->CountEntities(); ++t )
{
Entity* e = world->GetEntity(t);
if(e->GetKeyValue("name") == name)
{
return e;
}
}

return 0;

}

Interesting code.

I didn't know we could go that way with countEntities().

It seems lot more natural linear programming than using callbacks, i'll give it a try.

Hi

 

Any tip how to do this in LUA ? Just installed the indie edition but have not worked with the LUA functions much.

This was just added today by an old member so it was in my head

 

We are trying to get that wiki established as a place we can all go and contribute whatever we can.

You can also access the "entities" member of the world, which is just a standard C++ list.
