CurrentWorld().Entities ?

[Gabriel]

Hello,

 

I wish I had access to all objects in my scene with the script editor (mesh,surface ...)

 

I tried this:

 

function class: CreateObject (model)
    local object = self.super: CreateObject (model)
    e = CurrentWorld().Entities
    f = FindChild (c, "couloir01_2") <- "EXECPTION_ACCESS_VIOLATION"
......

 

Between me and my editor, there is no way to talk about it continually meets EXECPTION_ACCESS_VIOLATION.

 

I'm trying to open dialogue, but nothing;-)

 

someone has an idea to reconcile myself with my editor?

f = FindChild (e, "couloir01_2")

I suggest adding the relevant entities into a table when they are created, so you can access them later.

 

If you are trying to find a child of that model, you would just call model:FindChild(name).

ok, but how can I manage that?, in my case, I use the script of models, for example when I place an object on the scene with the editor, I want this object if there is an object in the scene with which it can interact.

 

In this way the only thing I have to do is execute the loadScene ("myscene") and the rest is automatic as in the editor.

I had never programmed in LUA, I thought I LUA or Basic was the same. I'm stupid to believe it ^ ^

I bought a book on Lua and is more than a vulgar BASIC interpreter, I just found an incredibly powerful language, but not enough restrictive.

I say this because I found a solution to my problem and also with the help of "macklebee"

 

and as I would like to benefit everyone, here is how I solved my problem:

 

 

       Piste = {} -- as global

       local function FindEntityByName(name)
               for model in iterate(CurrentWorld().entities) do
                       if name == model:GetKey("Name") then 
                               return model
                       end
               end
               return nil
      end

       local function GetSurfaceCouloirByName(ModName)
               local ModPiste=FindEntityByName(ModName)
               assert(ModPiste~= nil,"pas trouvé de piste "..ModName.." dans la scène")
               local MeshPiste=ModPiste:FindChild("U3D_STATIC_MESH")
               assert(MeshPiste~= nil,ModName.."trouvé mais pas de mesh portant le nom U3D_STATIC_MESH")
               local NSurfacePiste=MeshPiste:CountSurfaces()
               assert(NSurfacePiste > 0,ModName.."->U3D_STATIC_MESH n'a pas de surface !!!")
               local SurfacePiste=MeshPiste:GetSurface(1)
               return SurfacePiste
       end

       local function StorePathToTable(NonPiste,Surface)
               local CntVertice = Surface:CountVertices()
               assert(CntVertice > 0,"la surface n'a pas de vertice ! <StorePathToTable(Surface)>")
               Piste[NonPiste] = nil
               Piste[NonPiste] = {}
               Piste[NonPiste][0] = Vec3(0)
               for i = 1,CntVertice  do
                       Piste[NonPiste][i] = Surface:GetVertexPosition(i)
               end
       end

       local function ShowPathList(NomPiste)
               local t = Piste[NomPiste]
               local lt = #Piste[NomPiste] - 1
               AppLog(lt)
               for i = 1,lt do
                       AppLog(t[i].x)
               end
       end

function class:CreateObject(model)
       local object=self.super:CreateObject(model)

       AppLog("Begin------------------------------")
               local TheSurface = GetSurfaceCouloirByName("Cou1")
               StorePathToTable("Piste1",TheSurface)
               ShowPathList("Piste1")
       AppLog("End ------------------------------")

 

;-) thank for all

hey Gabe... i'm sorta new to this lua mess as well... but, i think you're going through a lot of unnecessary trouble with this...

there should be no need for the extra function (FindEntityByName) just to find a child object of a scene...

 

all you need do to find a child object in a scene is something like in the code below...

 

Graphics(640,480)
RegisterAbstractPath("")
TFilter(1)
AFilter(16)

fw=CreateFramework()


scene=LoadScene("abstract::myNew3.sbx")
fw.main.camera:Movef(0,12,-5)

daynight=scene:FindChild("daynight_2");
daynight:SetKey("rate",4)

while(KeyHit(KEY_ESCAPE)==0 and AppTerminate()==0) do
fw:Update()
fw:Render()
SetBlend(1)
DrawText("Hello There",20,20)
SetBlend(0)
Flip()
end

 

this simple lil lua script loads a scene with Klepto's daynight object, finds the daynight object

and uses the found object variable to set the daynight update rate to 4...

 

ps... i'm using LW 2.50

 

good luck...
