How to remove a fixture from a body?

RogerT

Hi guys,
If I make a fixture like this

local shape = b2.CircleShape.new(0, 0, 40)
body.fix = body:createFixture{shape = shape, density = 10, restitution = 0.2, friction = 0.1, filter = filter}

then I can remove it using

body:destroyFixture(body.fix)

but how do I destroy it, if I load it from a file as here?

body.physics = (loadfile "virusA/virusA_collide.lua")().physicsData(1)
body.physics:addFixture(body, "virA")

Thanks! )

@RogerT do you use some physics editor that provides that file?

RogerT

yes

amm, ok. which one?
Basically I'm not using any so I still would not know, but what you can do, is to try to print all object/properties/methods underneath to find which object has the :destroyFixture(body.fix) method

you can use this print_r function

--recursive print of tables function print_r (t, indent, done) done = done or {} indent = indent or '' local nextIndent -- Storage for next indentation value for key, value in pairs (t) do if type (value) == "table" and not done [value] then nextIndent = nextIndent or (indent .. string.rep(' ',string.len(tostring (key))+2)) -- Shortcut conditional allocation done [value] = true print (indent .. "[" .. tostring (key) .. "] => Table {"); print (nextIndent .. "{"); print_r (value, nextIndent .. string.rep(' ',2), done) print (nextIndent .. "}"); else print (indent .. "[" .. tostring (key) .. "] => " .. tostring (value).."") end end end

And use it like:

print_r(body)
