Accessing floats from a different script - Stinged - 05.06.2016

I've been scripting for a while now, and I've never needed to access a float that's inside the gamemode, from a filterscript.

I've never had a problem when I access integers.
(I use CallRemoteFunction)

This is just an example of course:

Код:

Gamemode:
public Float: GetPlayerHealthEx(playerid)
{
    new Float: f;
    GetPlayerHealth(playerid, f);
    return f;
}

Filterscript:
CallRemoteFunction("GetPlayerHealthEx", "i", playerid);

Maybe I'm doing something completely stupid and I'm not noticing it, but it's not working.
I tried debugging, and all it did is make me more confused:

Код:

new
    Float: test = 100.0,
    Float: h = GetPlayerHealthEx(playerid);
printf("test: %f", test);
printf("h: %f", h);
if (test > h)
    print("test > h");

What it prints out:

Код:

test: 100.000000
h: 50.000000

The only way I'm getting it to work is by using PVars..

Have from the gamemode the public function with Float: tag to return the float value and in filterscript:

pawn Код:

new
    health = CallRemoteFunction("GetPlayerHealthEx", "i", playerid);

printf("health from fs: %f", Float: health);

You could also use PVars ([G/S]etPVarFloat)

I did change it to that before making this thread, but I prefer using normal variables.

Thank you Konstantinos, it works!

Damn it..

I give you some advice, do not create a variable equivalent to HP, as with GetPlayerHealthEx function return the float value

pawn Код:

printf("h: %f", h);

change in

pawn Код:

printf("h: %f", GetPlayerHealthEx(playerid));

Re: Accessing floats from a different script - Stinged - 05.06.2016

I was only giving an example, but creating a variable and setting it to something, and then using that variable multiple times it better than using CallRemoteFunction multiple times.

Код:

new Float: h = CallRemoteFunction("GetPlayerHealthEx", "i", playerid);
if (h ...)
else if (h ...)
printf("%f", h);
SetPlayerHealth(playerid, h);

is better than

Код:

if (CallRemoteFunction("GetPlayerHealthEx", "i", playerid) ...)
else if (CallRemoteFunction("GetPlayerHealthEx", "i", playerid) ...)
printf("%f", CallRemoteFunction("GetPlayerHealthEx", "i", playerid));
SetPlayerHealth(playerid, CallRemoteFunction("GetPlayerHealthEx", "i", playerid));

Re: Accessing floats from a different script - Nero_3D - 05.06.2016

The problem is that CallRemoteFunction don't know the correct tag and treats the float as integer

To save memory and the problem with the tag you should either create a function or use native

With native this could look like

PHP код:



// Float: GetPlayerHealthEx(playerid) - returns current health

native Float: _GetPlayerHealthEx(func[] = "GetPlayerHealthEx", form[] = "i", {Float, _}: ...) = CallRemoteFunction;

#define GetPlayerHealthEx( _GetPlayerHealthEx(_,_,

Thank you Nero_3D.
Would there be any difference in speed and memory usage if I do this:
[/code]#define GetPlayerHealthEx(%0) Float: CallRemoteFunction("GetPlayerHealthEx", "i", %0)[/code]
Instead of what you posted?

Speed-wise it would be the same but memory-wise not, if you do it like that both strings would be placed again and again into the memory, with the natives it would be as if you had declared both string global and reuse them each time

Alright, thanks for the help.
