Additional vectors to send in case the extern is an array. Sets the sleeping behaviour of the body. Normally the same thing will be drawn on each canvas, but that can be changed if a pixel shader is used with the "effects" function instead of the regular effect.Not all computers support Canvases, and not all computers which support Canvases will support multiple render targets. This method does not reset any previously applied transformations. True if the body is allowed to sleep or false if not. only vec3's). world_x, world_y = Body:getWorldVector( local_x, local_y ).

A sawtooth wave, also known as a ramp wave. love.filesystem.setIdentity( name, searchorder ). This can be used, for example, to draw repeating copies of a single background image.A SpriteBatch can be even more useful when the underlying image is a Texture Atlas (a single image file containing many independent images); by adding Quad to the batch, different sub-images from within the atlas can be drawn. True if the game is in fused mode, false otherwise. )The paths are relative to the game's source and save directories, as well as any paths mounted with love.filesystem.mount.

This is done either with love.filesystem.setIdentity or by setting the identity field in love.conf. The x component of force to apply to the center of mass. The first joint to connect with a gear joint. For example, if this function is used with a GUID returned by a Dualshock 3 controller in OS X, the binding will affect Joystick:getGamepadAxis and Joystick:isGamepadDown for ''all'' Dualshock 3 controllers used with the game when run in OS X.LÖVE includes built-in gamepad bindings for many common controllers. The new value for the second component of the attribute. The number of sources which are currently playing or paused. xmin, ymin, xmax, ymax = ParticleSystem:getLinearAcceleration().

RGBA data at 4 bits per pixel. Restricts the drawn vertices of the Mesh to a subset of the total.If a vertex map is used with the Mesh, this method will set a subset of the values in the vertex map array to use, instead of a subset of the total vertices in the Mesh.For example, if Mesh:setVertexMap(1, 2, 3, 1, 3, 4) and Mesh:setDrawRange(4, 6) are called, vertices 1, 3, and 4 will be drawn.
