Variables in model

[Gilmer]

Hi peoples...

Im having the follow problem: I have a model called trigger2. Always that I create a new trigger2 in editor, it is called as "trigger2_x_y", where 'x' is the ID, 1,2,3,4....and 'y' is the fx that will received, that is set in own properties. I.e, if I create the first 'trigger2' in scene, with the fx set to '0', it name as "trigger2_0_0", if I create other in the scene, it is named as "trigger2_1_0", and so on.

 

The problem is each trigger2 that I create in the scene, is add a value in the first trigger too, and not only in last trigger. If have 10 trigger in the scene, the first trigger, is named as "trigger2_0_1_3_4_5_9_5_6...."..

 

I think that something with the global variables in the own class model. But dont know how solve this..

 

This is the trigger code:

 

require("scripts/class")
local class=CreateClass(...)

function class:InitDialog(grid)
self.super:InitDialog(grid)
group=grid:AddGroup("Tipo")
group:AddProperty("tipofx",PROPERTY_CHOICE,"0,1,2,3,4,5,6,7,8,9,10","Tipo Fx")
group:Expand(1)
end

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

local mesh=nil

object.model:SetKey("tipofx","0")

if(n~=nil) then n=nil end
if(n2~=nil) then n2=nil end
if(id~=nil) then id=nil end
if(id2~=nil) then id2=nil end


id=0
id2=0
function object:SetKey(key,value)
	if key=='tipofx' then --overrides color setting
		n2 = n.."_"..value
		object.model:SetKey("name",n2)
	end

	return 1
end


function object:Update()

	if debug==1 and mesh==nil then
		mesh=LoadModel("abstract::pista1_models_triggers_trigger3_trigger3mesh.gmf",model)
		model:SetShadowMode(0,1)
		mesh:SetKey("name",model:GetKey("name"))
	elseif debug == 0 and mesh ~= nil then 
		mesh:Free()
		mesh=nil
	end

	if(id2==0) then
		n=object.model:GetKey("name")
		n2 = n.."_"..object.model:GetKey("tipofx")

		n=object.model:GetKey("name")
		local fx=object.model:GetKey("tipofx")
		local n2=n.."_"..fx
		self.model:SetKey("name",n2)
		id2=1
	end
end


function object:Collision(entity,position,normal,force,speed)
	if chave==0 then
		Trigger()
		chave=1	
	end	
end


function object:Free(model)

	if mesh~=nil and debug==0 then	
		mesh:Free()
		mesh=nil
	end

end


end

anyone? I really need it..

 

One other doubt, I need use this function:

http://newtondynamics.com/wiki/index.php5?title=NewtonBodyGetMatrix

 

I searched in Wiki something seems, but I only found the GetEntityMatrix(), and nothing to use in a Body entity. Have some command like this? And if possible, to use in LUA..

I don't understand what the fx is used for? Also when you add new models (triggers could be a model) it already gets a unique name.

 

Why do you need this kind of naming convention. Knowing why might help us help you better.

So, I have three trigger types:

1: to determine the progress of player in the scene.

2: THIS of my example, that is to activate some fx, like audio fx, post process etc...

3: a fence to limit the car in the road, when the car over this trigger, he is brought back to road.

 

In the car player script have a function Collide, when it collides with some trigger, is sent a menssage to c++ code(ReceiveMessage()) with the name of the trigger collided. For this, the naming convention. If it collided in the trigger type 3 for sample, is sent this message: "trigger3_4", so, the car will positioned in the last trigger1 that has been collided.

 

In the case of Trigger2, in the second number("trigger2_x_y"), the "y", is the fx(if 1:sound x, if 2: postfx x....etc), but the first number, the "x", is need be different, cause when the c++ receive the message with the name, is stored in a array, and "x" is the index of this array.

 

I tried explain better my problem, my english no help much...hehe

But if need, I try explain in other way..
