# Unigine::BodyCloth Class (CPP)

**Header:** #include <UniginePhysics.h>

**Inherits from:** BodyParticles


This class is used to simulate a flat deformable [cloth bodies](../../../principles/physics/bodies/cloth/index.md). They use a [mass-spring simulation model](../../../principles/physics/bodies/cloth/index.md#model): the cloth is formed from [particles](../../../api/library/physics/class.bodyparticles_cpp.md) (of sphere shape) that are located in the cloth mesh vertices and connected by inner joints.

## BodyCloth Class

### Members

## int getNumIndices () const

Returns the current number of particle indices in the cloth body.
### Return value

Current number of particle indices
## void setTwoSided ( int sided )

Sets a new value indicating if the cloth is one- or two-sided (1 - two-sided, 0 - one-sided). If two-sided, its material should not be [two-sided](../../../api/library/rendering/class.material_cpp.md#setTwoSided_int_void) at the same time.
### Arguments

- *int* **sided** - The cloth two-sided flag

## int getTwoSided () const

Returns the current value indicating if the cloth is one- or two-sided (1 - two-sided, 0 - one-sided). If two-sided, its material should not be [two-sided](../../../api/library/rendering/class.material_cpp.md#setTwoSided_int_void) at the same time.
### Return value

Current cloth two-sided flag
---

## static BodyClothPtr create ( )

Constructor. Creates a cloth body with default properties.
## static BodyClothPtr create ( const Ptr < Object > & object )

Constructor. Creates a cloth body with default properties for a given object.
### Arguments

- *const [Ptr](../../../api/library/common/class.ptr_cpp.md)<[Object](../../../api/library/objects/class.object_cpp.md)> &* **object** - Object represented with the new cloth body.

## int getParticleIndex ( int num )

Returns the particle index by its number.
### Arguments

- *int* **num** - The particle index number.

### Return value

The particle index.
