Detailed Description

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).

Member Enumeration Documentation

◆ Enum

Enumerator
eAVERAGE 

Average: (a + b)/2.

eMIN 

Minimum: minimum(a,b)

eMULTIPLY 

Multiply: a*b.

eMAX 

Maximum: maximum(a,b)

eN_VALUES 

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.

ePAD_32 

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