random number generator helper class
◆ RNG()
| skr::pcg::RNG::RNG |
( |
bool |
printSeed = false | ) |
|
constructor uses random seed
- Parameters
-
| printSeed | set true to print seed to cmd and log, otherweise false. Default: false |
◆ CheckViableSeed()
| bool skr::pcg::RNG::CheckViableSeed |
( |
uint32_t |
seed | ) |
|
|
private |
check if a given seed is not on the blacklist this is easy solution/hack to prevent levels with overlapping rooms, etc. to be generated
- Parameters
-
- Returns
- true if seed is not on blacklist, otherwise false
◆ GenerateViableSeed()
| uint32_t skr::pcg::RNG::GenerateViableSeed |
( |
| ) |
|
|
private |
Generates a new seed that is checked to be viable.
- Returns
- seed value that is not on blacklist
