[41.29] Automated Emergency Broadcast System RNG generates odd floating point numbers

[the-phil]

Radio/Walkie presets only allow even numbers in the floating points. Automated Emergency Broadcast System (AEBS) can generate odd floating point numbers.

 

It looks like radios and walkies allow you to add frequencies ending with an even floating point number. Such as #.0 #.2 #.4 #.6 etc.

One of my saved games came up with the AEBS frequency as 96.1, however I can only set the radio/walkie frequencies to 96 or 96.2. Spawned in radios will show a preset of "96.1 MHz Automated Emergency Broadcast Syst" set properly and function as intended.

 

My workaround:

In the ~/Zomboid/Saves/<Type>/<Savedgame>/radio/data/RADIO_SAVE.txt the last entry shows the AEBS frequency "96100,1,1,GEN-155944,-1" The 4th field would be replaced with a new string when in game broadcasts occurred. I attempted to modify the first field only to have it overwritten at the turn of the hour.

 

Played around and found a not human friendly sequence in map_t.bin

code block was really hard to read... tried to delete... it must be sentient... deleted the data... it might repopulate...

The save with the frequency 96.1 looked like this

000000D0  01 40 F7 76  40

modified it to match the frequency 98.6

000000D0  01 40 F8 12  80

This allowed me to set the frequency to 98.6 with the radios and walkies.
