Last few days I was looking at commands that use sscanf and I always see this condition:

pawn Code:

if (sscanf(params, "s", string)) SendClientMessage(playerid, COLOR_SOMETHING, "Usage: /command <string>");

But I will not need that in my every command because there will be 2-3-4 or more parameters and I don't want it to always return the same message.

So if the player types only for example "/safe" it will return message like "USAGE: /safe <option>" and if the player types "/safe put" it will return message "USAGE: /safe put <item>".

So this command in first post is written just fine?

And one more question... Can I use sscanf more that one time in one command?
Like if on second parameter there is one more parameter but only when I type "gun".

Example

Code:

/safe put gun gunid amount

and

/safe put drugs amount

So first it would be

pawn Code:

sscanf(params, "ss", option, item);

but under the "gun" check can I add this:

pawn Code:

sscanf(params, "is", gunid, amount);

and under the "drugs" check something like this

pawn Code:

sscanf(params, "s", amount);

And if I can do that should this part be changed sscanf(params, ...) or it stays that way?
