Applies only to
"pulley" joint, indicates the current joint ratio. For this joint type, this property is
1.0 which simulates a simple pulley.
"gear" joint, this property can be either set or read, and it indicates the ratio at which the
local pulleyJoint = physics.newJoint( "pulley", bodyA, bodyB, anchorA_x, anchorA_y, anchorB_x, anchorB_y, bodyA.x, bodyA.y, bodyB.x, bodyB.y, 1.0 ) print( pulleyJoint.length1 ) print( pulleyJoint.length2 ) print( pulleyJoint.ratio )
local gearJoint = physics.newJoint( "gear", bodyA, bodyB, joint1, joint2, 1.0 ) print( gearJoint.ratio ) -- Change gear joint ratio gearJoint.ratio = 0.4
