AlliedModders - Good way to take screenshot on player?

If it's a bad old cheat yes there are ways to trick the function that checks for snapshots, you see the old cheats disable visuals before it gets fired on your client, and turn it back on straight after, you could trick the old ones but the newer ones have better solutions against that.

You used to set task somebody with a snapshot in very small intervals so the cheat would turn off before the first one and then turn visuals back on right after, it does a call to resethud afaik so if you draw HUD messages in-between the tasks and set animations on them then you can clearly see which photos were from a cheater and which wasn't because you can clearly see abrupt and missing text.

Either way that method is useless if someone is drawing on steam overlay or just in general not internally and there are far easier methods of cheating than injecting.

Old netshark packet sniffing should be completely undetectable, preventable though with whblocker mm module.
