[LUA] Collision:SetResponse() causes error

[macklebee]

The request had been to implement user defined collision types and responses as shown in this post: http://www.leadwerks.com/werkspace/topic/9109-collision-response-types/#entry73689

 

And the documentation page says that the programmer can change the default collision responses, but whenever 'Collision:SetResponse()' is used it will error out with 'argument #1 is class Collision; Collision expected'.

 

Example code - uncomment the line to cause the error:

function App:Start()
 --Create a window
 self.window = Window:Create()
 self.context = Context:Create(self.window)
 self.world = World:Create()
 local camera = Camera:Create()
 camera:SetRotation(35,0,0)
 camera:Move(0,0,-8)
 local light = DirectionalLight:Create()
 light:SetRotation(35,35,0)

 --Create the ground
 local ground = Model:Box(10,1,10)
 ground:SetColor(0.0,1.0,0.0)

 --Create a shape
 local shape = Shape:Box(0,0,0, 0,0,0, 10,1,10)
 ground:SetShape(shape)
 shape:Release()

 --Create a model
 self.entity1 = Model:Box()
 self.entity1:SetColor(0.0,0.0,1.0)
 self.entity1:SetPosition(-2,3,0)
 self.entity1:SetMass(1)
 self.entity1:SetCollisionType(2)

 --Create a shape
 shape = Shape:Box()
 self.entity1:SetShape(shape)
 shape:Release()

 --Create a second model
 self.entity2 = self.entity1:Instance()
 self.entity2:SetPosition(2,3,0)
 self.entity2:SetCollisionType(13)
--Collision:SetResponse(1,13,true)---UNCOMMENT THIS LINE TO CAUSE ERROR
 return true
end
function App:Loop()

 if self.window:Closed() or self.window:KeyHit(Key.Escape) then return false end
 Time:Update()
 self.world:Update()
 self.world:Render()
 self.context:SetBlendMode(Blend.Alpha)
 self.context:DrawText("Entity 1 collision type: "..self.entity1:GetCollisionType(),2,2)
 self.context:DrawText("Entity 2 collision type: "..self.entity2:GetCollisionType(),2,22)
 self.context:Sync()
 return true
end

Thank you. The function was not declared as a static function, which it should have been.

 

BTW, the third argument is a number, not a boolean:

0: no response

1: collide

2: trigger
