physics.addBody() with custom shapes in Corona SDK

Question

Does the physics.addBody() only work with Circles and Rectangles? Or is it possible to physics.addBody() on vector shapes or sprites or with masks or something?

Answer 1

It is possible to do with sprites and shapes, see here .

local physics=require("physics")
physics.start()
physics.setDrawMode("hybrid")
local obj=display.newRect(160,600,50,50)
physics.addBody(obj,"static", {density=0.1,friction=0.1} )

local obj=display.newCircle(90,500,50)
physics.addBody(obj, "static", {density=0.1,friction=0.1,radius=50} )

--equilateral triangle physics object
local rad=30/360*2*math.pi
local xHalfLen=80*math.sin(rad)
local yLen=80*math.cos(rad)

local obj=display.newLine(100,100, 100+xHalfLen,100+yLen)
obj:append(100-xHalfLen,100+yLen, 100,100)
obj.width=3
obj:setColor(255,120,120)

local triangleShape={0,0, xHalfLen,yLen, -xHalfLen,yLen}    
--center of object is at top of triangle
physics.addBody(obj, {density=0.1,friction=0.1,shape=triangleShape} )

the shapes must be convex and consists of less than 8 sides.
