"Nil value" ?

[SpiderPig]

I'm learning lua but keep getting error messages with functions like "SetPosition", "Translate" and "Move"....

What am I doing wrong here?

 

require("scripts/class")

local class=CreateClass(...)

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

       function object:UpdateMatrix()
           object:Translate(Vec3(1),1)
end

end

uh. you are moving the object every time the matrix is updated? looks like a you are creating an infinite loop...

 

as for the error, use 'object.model' or just 'model' when using Entity commands as the 'object' itself is not an entity...

Yes, I want to move the object every time it updates, am I right in assuming that the "UpdateMatrix" function is automatically called?

 

As for the error - I tried;

 

function object:UpdateMatrix()
 object.model:Translate(Vec3(1),1)
end

 

but now I get another error 'Failed to open file "C:/Leadwerks Engine SDK/error in error handling" '.

 

It seems to only have a problem inside the "UpdateMatrix" function itself....

[macklebee]

what exactly are you trying to accomplish? just constant movement? then just use the 'object:Update()' function... i would assume the error is from you creating an infinite loop that calls itself from inside its own function... you would have the same problem if you did the same with any other function that called itself from inside itself... like using 'object.model:SetKey("name","killerclown")' inside the 'object:SetKey(key,value)' function...

I'm just trying to get constant movement of the object - so it seems I wasn't using the right function... my newness to lua is the problem here

Many thanks macklebee!
