Scene managment again

[VeTaL]

Okay, i have a building model and some detail models like stones, so the building is main models and stones are detail models.

 

First, i want those stones to be ignored by Newton, so i wanted to add some LUA scripting: "house" is created in editor, then its form is calculated as Convex Hull, and then artist can add stones as he want, but they would be ignored by physic. (right picture)

What is the best solution for this?

 

Second, can i be sure that all that same models (buildings are the same model, all bricks are also the same models) are rendered using instancing? (left picture)

Third: when i clicked on building class (as its written in Getting_Started_With_Lua.pdf) and paste here

require("Scripts/class") 

local class=CreateClass(...) 

function class:InitDialog(propertygrid) 
 local group=propertygrid:AddGroup("MyGroup") 
 group:AddProperty("MyValue",PROPERTY_STRING) 
end

and run it, i got a crash "table index is nil" in class.lua, in string "classtable[modelreference]=class"

Also, there is no collisions between player and buildings (but there is collisions between player and terrain), even with

Collisions(1,1,1);
EntityType(player.GetPlayerBody(), 1);
EntityType(scene.GetScene(), 1);

Because you don't run it.

like Marleys Ghost is saying:

Don't run your class script! just save it. Only a game sript (like fpscontroller.lua) can be run.

 

If your model doesn't have a phy file, then the editor automaticly creates one for you when you drag the object into your scene. I would build the main model in your 3d program and give it a convex hull physics shape. Then i would export the stones sepperatly and make no physics file for them. Then with code you can attach the stones to your model:

 require("scripts/class")

local class=CreateClass(...)

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

--load the stones
self.stones=LoadModel	("abstract::stones.gmf")

--position stones or use the offset by exporting
self.stones:SetPosition(Vec3(-2.3,2.41,-1.79))


--parent stones to the main model
self.stones:SetParent	(object.model)
--done with parenting


function object:Free(model)
	self.super:Free()
end

end

 

instead of getplayerbody. U can perhaps just use : player. remember to set it to a global object. Setglobalobject("playercontroller",player)

Thanks, guys, maybe i'll make my first "user's contribution" with this theme.

Emm.. I added to LUA

require("scripts/class")

local class=CreateClass(...)

function class:InitDialog(propertygrid) 
 self.super:InitDialog(propertygrid) 
 local group=propertygrid:AddGroup("Stones") 
   group:AddProperty("StoneNumber", PROPERTY_INTEGER )
 group:AddProperty("StonePosition", PROPERTY_VEC3 )
end

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

       --load the stones
       self.stones=LoadModel   ("abstract::Dec01.gmf")

       --position stones or use the offset by exporting
       self.stones:SetPosition(Vec3(-4,6,-0.7))


       --parent stones to the main model
       self.stones:SetParent   (object.model)
       --done with parenting


       function object:Free(model)
               self.super:Free()
       end

end

 

but still have physic on stones
