how do I make it put like invaild name if someone does 3 letters and under?
like

SendClientMessage(playerid, COLOR_RED, "Invaild name"

But how do I make it detect if it invaild?

3 and under letters (invaild)

if (4 > strlen(newname) > 24) return // your message here saying their name is under 4 or over 24 and invalid

i added the check for over 24 also, even though your string is set for size 24 so really you wont need that just

pawn Код:

if (4 > strlen(newname) ) return // your message here saying their name is under 4

I can still change my name to like 0
and 00000000000000000000000000000000000000000000000000 0000
