Identifying self within Flip() [resolved]

[Rekindled Phoenix]

My goal is to cycle all of the entities, and exclude the object that is invoking the event. The problem is that the function attached to AddHook() doesn't have a reference to the object that attached the hook. Seems the AddHook() function can only be passed a delegate (.Net reference) without parameters.

 

(Since the objects I will be adding are not sorted in order, indexes aren't an option)

 

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

AddHook("Flip", UpdateCycleThru(object)) --fails 

function object:Free(model)
	RemoveHook("Flip", UpdateCycleThru(object)) --fails
	self.super:Free()
       end
end

function UpdateCycleThru(object)
       -- Cycle through nodes applying a draw method, except for self
end

 

So my question is, how does an object identify itself from the rest of the objects within the scene, when the function is called outside of the Class overrides?

 

Looking further into this issue, I may have to cycle through these objects using an external script marshaller...

Looks like the issue is resolved. Instead of trying to access the within each object, I create a 'marshaller' that does the drawing for the necessary objects.

 

function UpdateCablesCycleThru()
--model,object
for k1,v1 in pairs(objecttable) do
	if v1.type ~= nil then
		if v1.type == NavTypeName then
			local Pos2 = CameraUnproject(fw.main.camera, k1.position)
			DrawPath(Pos2)
		end
	end
end
end

function DrawPath(Pos2) --Used for each object

for k,v in pairs(objecttable) do
	if v.type ~= nil then
		if v.type == NavTypeName then --inherited from 'PhoenixPath'
                               -- Draw elements using both positions
                               local Pos = CameraUnproject(fw.main.camera, k.position)
			DrawLine(Pos2.x, Pos2.y, Pos.x, Pos.y)
		end
	end
end
end
