Source:isRelative Available since LÖVE 0.9.0 This function is not supported in earlier versions. Gets whether the Source's position, velocity, direction, and cone angles are relative to the listener. Function Synopsis relative = Source:isRelative( ) Arguments None. Returns boolean relative True if the position, velocity, direction and cone angles are relative to the listener, false if they're absolute. See Also Source Source:setRelative

love.mousereleased Callback function triggered when a mouse button is released. Function Available since LÖVE 0.10.0 This variant is not supported in earlier versions. Synopsis love.mousereleased( x, y, button, istouch ) Arguments number x Mouse x position, in pixels. number y Mouse y position, in pixels. number button The button index that was released. 1 is the primary mouse button, 2 is the secondary mouse button and 3 is the middle button. Further buttons are mouse dependent. boolea

love.joystick.getName Removed in LÖVE 0.9.0 It has been moved to Joystick:getName. Returns the name of a joystick. Function Synopsis name = love.joystick.getName( joystick ) Arguments number joystick The joystick to be checked Returns string name The name See Also love.joystick

ParticleSystem:count Removed in LÖVE 0.9.0 It has been renamed to ParticleSystem:getCount. Gets the amount of particles that are currently in the system. Function Synopsis count = ParticleSystem:count( ) Arguments None. Returns number count The current number of live particles. See Also ParticleSystem

BezierCurve:getDerivative Available since LÖVE 0.9.0 This function is not supported in earlier versions. Get the derivative of the Bézier curve. This function can be used to rotate sprites moving along a curve in the direction of the movement and compute the direction perpendicular to the curve at some parameter t. Function Synopsis derivative = BezierCurve:getDerivative() Arguments None. Returns BezierCurve derivative The derivative curve. See Also BezierCurve love.math

Body:getAngularDamping Gets the Angular damping of the Body The angular damping is the rate of decrease of the angular velocity over time: A spinning body with no damping and no external forces will continue spinning indefinitely. A spinning body with damping will gradually stop spinning. Damping is not the same as friction - they can be modelled together. However, only damping is provided by Box2D (and LOVE). Damping parameters should be between 0 and infinity, with 0 meaning no damping,

enet.peer:receive Attempts to dequeue an incoming packet for this peer. Returns nil if there are no packets waiting. Otherwise returns two values: The string representing the packet data, and the channel the packet came from. Function Synopsis peer:receive() Arguments None. Returns string data Data from the received packet in a string. number channel Channel the packet was received from. See Also lua-enet enet.peer

PrismaticJoint:getLowerLimit Gets the lower limit. Function Synopsis lower = PrismaticJoint:getLowerLimit( ) Arguments None. Returns number lower The lower limit, usually in meters. See Also PrismaticJoint

World:getBodyList Available since LÖVE 0.8.0 This method is not supported in earlier versions. Returns a table with all bodies. Function Synopsis bodies = World:getBodyList( ) Arguments None. Returns table bodies A sequence with all bodies. See Also World

World:setContactFilter Available since LÖVE 0.8.0 This method is not supported in earlier versions. Sets a function for collision filtering. If the group and category filtering doesn't generate a collision decision, this function gets called with the two fixtures as arguments. The function should return a boolean value where true means the fixtures will collide and false means they will pass through each other. Function Synopsis World:setContactFilter( filter ) Arguments function filter
