Available since: Gideros 2011.6
Class: b2


Creates and returns a prismatic joint definition table with the bodies, anchors, axis, and reference angle using the world anchor and world axis.

(Please refer to b2.World:createJoint function for more information about all the information needed to create a prismatic joint).

(table) = b2.createPrismaticJointDef(bodyA,bodyB,anchorx,anchory,axisx,axisy)


bodyA: (b2.Body) the first attached body
bodyB: (b2.Body) the second attached body
anchorx: (number) the x coordinate of the world anchor point
anchory: (number) the y coordinate of the world anchor point
axisx: (number) the x coordinate of the world axis
axisy: (number) the y coordinate of the world axis

Return values

Returns (table) A new prismatic joint definition table


--create empty box2d body for joint
local ground = world:createBody({})
ground:setPosition(465, 480)

--axisx, axisy values usually between 0 and 1
--0 0 moves freely
--0 1 moves on y axis
--1 0 moves on x axis
--1 1 moves on diagonal
local jointDef = b2.createPrismaticJointDef(body, ground, 350, 100, 0.3, 1)
local prismaticJoint = world:createJoint(jointDef)
