Sets a new body mass.

Function

Available since LÖVE 0.8.0
This variant is not supported in earlier versions.

Synopsis

body:setMass( mass )

Arguments

number mass
The mass, in kilograms.

Returns

Nothing.

Function

Removed in LÖVE 0.8.0
This variant is not supported in that and later versions.

Sets the mass properties directly.

If you're not sure what all this stuff means, you can use Body:setMassFromShapes after adding shapes instead.

The first two parameters will be the local coordinates of the Body's center of mass.

The third parameter is the mass, in kilograms.

The last parameter is the rotational inertia.

Synopsis

body:setMass( x, y, m, i )

Arguments

number x
The x-component of the center of mass in local coordinates.
number y
The y-component of the center of mass in local coordinates.
number m
The mass, in kilograms.
number i
The rotational inertia, in kilograms per squared meter.

Returns

Nothing.
