EDIT: Another Question: How would I get a players health then subtract like -5 health from it? Using GetPlayerHealth and SetPlayerHealth, Thanks.

[MP2]

pawn Код:

PlayerInfo[playerid][pHunger]-=69;

Decrease by 69.

[TheLazySloth]

PlayerInfo[playerid][pHunger] -= 255;

Theres (http://wiki.amxmodx.org/Pawn#Expressions)
= : Set
++ : Add 1
-- : Minus 1
+= : Add
-= : Subtract
*= : Multiply
/= : Divide
... And more but these are real basic Mathmatical Operators.

Updated main post with another help question

[Calgon]

pawn Код:

new Float: fHealth;
GetPlayerHealth(playerid, fHealth);
SetPlayerHealth(playerid, fHealth-5);

Subtraction with floats is just as simple as it is with integers.

Thanks everyone, you guys helped me create my hunger system!

Heres how I would do it:

pawn Код:

new health;
health = GetPlayerHealth(playerid);
health = health-5;
SetPlayerHealth(playerid, health);

EDIT: I was too late with my answer ^ ^ :P Someone got there first

^ Unneed lined though and it's a variable not a float.

That wouldn't work, GetPlayerHealth returns a float to the variable that is the second parameter of the function, you can't use integers and you've written the function parameters incorrectly.
