Expand 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).
Variants§
Average
Average: (a + b)/2
Min
Minimum: minimum(a,b)
Multiply
Multiply: a*b
Max
Maximum: maximum(a,b)
NValues
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
This is not a valid combine mode, it is to assure that the size of the enum type is big enough.
