am build a plugin and i need get a float argument to my function

sorry for me bad english

[Terminator3]

amx_ctof(params[1]) ?? this always returns 0.00000

[Terminator3]

Код:

static cell AMX_NATIVE_CALL n_gpfa( AMX* amx, cell* params )
{
	double x = amx_ctof(params[1]);
	logprintf("distance: %f", x);

native gpfa(&Float:distance);

ok thx

one more: what is the PI number in float ?? 3.14 ... is a double and i need float

[Aleks10]

PI... 'f'(in end)
or (float)PI

[hencz]

I use floats. I think most of the games use floats. Correct me if I'm wrong.
Is there a noticeable difference between floats and doubles?

2 more questions

1. how to use sa:mp function, i need IsPlayerConnected

and 2. how to use public function, OnPlayerDisconnect (after is load in gamemodes & filterscripts)

[Terminator3]

the max functions argument value is 2147483647 ?? more get a negative value

PawnCommand, if you have the patience to fiddle around with it.

Call it from the gamemode...

public OnPlayerDisconnect(playerid, reason) return plugin_OnPlayerDisconnect(playerid,reason);

Or if you're up for a challenge you could try the memory hacking approach, but that's frowned upon here.

i have probably PawnCommand but how to use it ?

i need one simple function, IsPlayerConnected

There was someone (I can't remember who) posting an "invoke" package including the SDK, tutorials and pawn command with examples.
Here is it:
http://remis.square7.net/tests/Plugi...okePackage.zip
or look at my attachment.

Read the "Usage(README).txt":

Quote:

-Using PAWN functions in your plugin --------------------------------------------------------------------- **View the examples in action in the "HelloWorld/helloworld.cpp" file!!! Parameters: i = integer f = float value s = string v = variable p = string var (GetPlayerName etc.) There are 5 types of parameters that can be used for PAWN functions. All parameters except variables ("v") and string variables ("b") can be used directly, as in this example: //PutPlayerAtCenterOfWorld(int playerid) int playerid = params[1]; float x = 0.0,y = 0.0,z = 0.0; PawnCommand(&SetPlayerPos,playerid,x,y,z); To use variable, you must use the "&" sign before the variable/stringvariable, as in this example: GetPlayerPositionAndPrint(int playerid) int playerid = params[1]; float x,y,z; PawnCommand(&GetPlayerPos,playerid,&x,&y,&z); You use the & sign to store the value of whatever you are getting.

And here is the PawnCommand readme by Peter:
http://pastebin.com/KusHkBAd (included in the package).

But Iam sure SSI, YSF and the streamer plugin have a better way of doing this, just look into their source code.

I never had much luck getting Peter's invoke working. I suggest extracting Incognito's from his streamer source code. His works perfectly.

Which one is faster?
