INFINITY
infinity = physics.misc.INFINITY()
Parameter | Type | Description |
---|---|---|
infinity | out number | Infinity |
Returns a number representing infinity in the physics engine.
Introduced in platform.apiLevel = '2.0'
momentForBox
inertia = physics.misc.momentForBox(mass, width, height)
Parameter | Type | Description |
---|---|---|
mass | in number | The mass of the box |
width | in number | The width of the box |
height | in number | The height of the box |
inertia | out number | The inertia of the box |
This routine computes the moment of inertia for a solid box. This is a useful helper routine for computing the moment of inertia as an input to the physics.Body(...) constructor.
Introduced in platform.apiLevel = '2.0'
momentForCircle
inertia = physics.misc.momentForCircle(mass, innerRadius, outerRadius, offBody)
Parameter | Type | Description |
---|---|---|
mass | in number | The mass of the circle |
innerRadius | in number | The inner radius of the circle |
outerRadius | in number | The outer radius of the circle |
offset | in physics.Vect | The offset of the circle from the center of gravity |
inertia | out number | The inertia of the circle |
This routine computes the moment of inertia for a circle. A solid circle has an inner radius of 0. This is a useful helper routine for computing the moment of inertia as an input to the physics.Body(...) constructor.
Introduced in platform.apiLevel = '2.0'
momentForPoly
inertia = physics.misc.momentForPoly(mass, vertices, offset)
Parameter | Type | Description |
---|---|---|
mass | in number | The mass of the polygon |
vertices | in physics.Vect | A list of vertices defining the shape of the polygon |
offset | in physics.Vect | The offset of the polygon from the center of gravity |
inertia | out number | The inertia of the polygon |
This routine computes the moment of inertia for a polygon. This is a useful helper routine for computing the moment of inertia as an input to the physics.Body(...) constructor.
Introduced in platform.apiLevel = '2.0'
momentForSegment
inertia = physics.misc.momentForSegment(mass, endPointA, endPointB)
Parameter | Type | Description |
---|---|---|
mass | in number | The mass of the segment |
endPointA | in physics.Vect | The point defining one end of the segment |
endPointB | in physics.Vect | The point defining the other end of the segment |
inertia | out number | The inertia of the segment |
This routine computes the moment of inertia for a segment. The end points can be in either world or local coordinates. This is a useful helper routine for computing the moment of inertia as an input to the physics.Body(...) constructor.
