Syntax
struct FNiagaraSimCacheCompare
Remarks
Allows you to compare two simulation caches for equality, or approximate equality. Due to platform differences simulations may not be equal when comparing one generates from one platform to another. Therefore you may need to be more flexible with some attributes, like positions, velocity, when comparing caches and adjust the tolerance accordingly. Note: This class is Experimental and the API may change
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
bool | bExcludeNoneDeterministicVariables | Should we exclude known none deterministic variables, i.e. ID / MaterialRandom. |
 |
bool | bIncludeDataInterfaces | Should we include data interface as part of the comparison. |
 |
float | DefaultFloatTolerance | Default float tolerance when comparing caches |
 |
TOptional< float > | DefaultQuaternionTolerance | Tolerance when comparing quaternions, if not set uses the default UE tolerance. |
