ForEachEntityInAABBDo to find entities

[martyj]

I have several entities that I'm trying to get a reference to a bunch of entities to be able to spawn copies of them.

 

All my entities are at the same location. (-100, -100, -100).

 

My code is as follows

 

function ParseWorldItemsCallback(entity, extra)
local name = entity:GetKeyValue("name")
System:Print("name:"..name);
end

function ParseWorldItems()
local aabb = AABB(-101, -101, -101, -99, -99, -99)

local world = World:GetCurrent();
world:ForEachEntityInAABBDo(aabb, "ParseWorldItemsCallback", nil);
end

My problem is that the name of the entity is empty string "".

 

Am I using ForEachEntityInAABBDo wrong? Or is there something wrong with how I'm getting the entity name?

 

Thanks,

Marty

hi

 

your aabb is nothing, both Points of the aabb box are in the same Location - very small box you scan.

Sorry my mistake, I was messing around with that to see if it was the AABB that was the problem. I changed the code back to had I first had it. That doesn't change the entity name problem I am having.

 

Both versions get entities passed to the callback. The problem is their name is empty.

Hi,

 

you have to set the "name" key first for each entity you want maybe in an other script attached to this entities.

 

do in new script in the start section an

 

self.entity:SetKeyValue("name","something")

Are you using Prefabs?

 

maybe you have these issues i reported here:

http://www.leadwerks.com/werkspace/topic/13055-prefabs-not-working-correctly/

 

 

the name key should also be set with the editor name field. No need to set it in code again.

[martyj]

I am not using prefabs. The name is set with the editor.

 

I believe the two may be related though.

Hi,

 

the Name in the LE Editor cannot proofen with GetKeyValue("name")

Try to set the key by code.(SetKeyValue("name","entity1"))

it should work, and as you see in my report, it sometimes work. but sometimes not. So it must be a bug.

The easier and less costly way is to make a table of prefabs, ie. PreFab{}, and then place a dummy of each in a distant place on the map with the editor to preload them at start. when you want one to be called (copied) just use the PreFab:Load(). this also lets you randomize spawns. If you have 5 zombie models you can call a math:random(1,5) and pass that as the table position and randomly pick the prefab to add some coolness. I have done this for mobs as well as items for drops before. It looks like this assuming you have populated a PreFab table with paths to the entities you want to spawn.

 

local random = math(1,5)

local spawn = PreFab:Load(PreFab[random])

spawn.SetPosition(whateverPos)

spawn.SetRotation(whateverRot)

spawn.script:Start()

 

you could copy the entity but if something happens to your master the copy will be messed up. with the preload you don't have that issue because you are making a fresh one when you need it but all the assets are already in memory because of the dummies.
