Remove shape via code

[Rick]

Shape* shape = Shape::Box(0,0,0, 0,0,0, 10,1,10);

ground->SetShape(shape);

shape->Release();

 

 

What's the proper way to remove a shape from an entity? Do I just pass in NULL? Is that good enough?

 

I assume calling SetShape() increases the ref counter? So by releasing it afterwards the ref count is 1, and if I call SetShape(NULL) it'll reduce it to 0?

Yep. I use SetShape(nil) in Lua and it works fine. It also reduces the shapes ref count to 0. I tested it with DebugPhysicsMode on to make sure. What I do for weapons is have them store their shape at the start like this -

 

function Script:Start()

self.shape=self.entity:GetShape()

self.shape:AddRef()

end

 

Then when my player picks up the weapon its shape is reduced to 0 by using self.entity:SetShape(nil). If I drop the weapon it gets its shape back from the self.shape I stored at the start. Like this -- self.entity:SetShape(self.shape). Then if I set the weapons shape to nil again I still have self.shape referenced so it can be used over and over again.

Perfect, that's what I'm looking for. It also looks like I can use 1 shape and set it to many models, which is nice!
