random with precents? - Lirbo - 19.01.2016

For example if a player has in his file: Luck=10 then the random will be 10% of success.
how can i do this?

PHP код:
new PlayerLuck[playerid];  // <------- Variable that player's luck stored in.
new rand = random(100);
if(0 <= rand && rand <= PlayerLuck[playerid]) return ... //> Success
else if(rand > PlayerLuck[playerid]) return ... //> Fail

A bit shorter:
PHP код:
new PlayerLuck[playerid];  // <------- Variable that player's luck stored in.
if(random(100) < PlayerLuck[playerid])
   //> Success (random gives a value from 0 to 9)
else
   //> Fail (random gives a value from 10 to 99) 
"random" returns values from 0 to value-1 (checking if "random" was below 0 is useless), so with the code above it can return values from 0 to 99, and we check if the valid value is from 0 to 9 (this would be 10%).

PHP код:
stock bool:IsDropAllow(chance){
    if(chance <= 0) return false;
    if(chance >= 100) return true;
    if((random(100)+1) <= chance) return true;
    return false;
}
