Even this is a little excessive; it's not necessary to hold the user's hand for the range validation, just as it's not necessary to use regex to check for non-numeric characters. Even if they omit an argument, I'd just go with it.
PHP Code:
public Action Command_EnterRGBA(int client, int args) {
if (client == 0 || !IsClientInGame(client)) {
ReplyToCommand(client, "[SM] You must be in-game to use this command!");
return Plugin_Handled;
}
char chRGBA[4][4];
int iRGBA[4];
for (int i; i < sizeof(chRGBA) && i < args; i++) {
GetCmdArg(i+1, chRGBA[i], sizeof(chRGBA[i]));
iRGBA[i] = StringToInt(chRGBA[i]);
if (!(0 <= iRGBA[i] <= 255)) {
iRGBA[i] = 0;
ReplyToCommand(client, "RGBA values must be between 0 and 255.");
}
}
// use RGBA how you want
return Plugin_Handled;
}
