Enum physx_sys::PxCombineMode

#[repr(i32)]
pub enum PxCombineMode {
    Average = 0,
    Min = 1,
    Multiply = 2,
    Max = 3,
    NValues = 4,
    Pad32 = 2_147_483_647,
}

Enumeration that determines the way in which two material properties will be combined to yield a friction or restitution coefficient for a collision.

When two actors come in contact with each other, they each have materials with various coefficients, but we only need a single set of coefficients for the pair.

Physics doesn’t have any inherent combinations because the coefficients are determined empirically on a case by case basis. However, simulating this with a pairwise lookup table is often impractical.

For this reason the following combine behaviors are available:

eAVERAGE eMIN eMULTIPLY eMAX

The effective combine mode for the pair is maximum(material0.combineMode, material1.combineMode).

Variants

Average = 0

Average: (a + b)/2

Min = 1

Minimum: minimum(a,b)

Multiply = 2

Multiply: a*b

Max = 3

Maximum: maximum(a,b)

NValues = 4

This is not a valid combine mode, it is a sentinel to denote the number of possible values. We assert that the variable’s value is smaller than this.

Pad32 = 2_147_483_647

This is not a valid combine mode, it is to assure that the size of the enum type is big enough.

Trait Implementations

impl Clone for PxCombineMode

fn clone(&self) -> PxCombineMode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PxCombineMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for PxCombineMode

fn eq(&self, other: &PxCombineMode) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
