Miscellaneous routines
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.
