[Tutorial] Simple Realistic Damage Values

[[ABK]Antonio]

I would do something along the lines of this.

public OnPlayerTakeDamage(playerid, issuerid, Float:amount, weaponid)
{
    new Float:stat[2];
    GetPlayerHealth(playerid, stat[0]);
    GetPlayerArmour(playerid, stat[1]);
    new Damage;
    switch(weaponid)
    {
        case 31: Damage = 25; //set the damage here for when this switch is over
    }
    if(stat[1] > Damage) SetPlayerArmour(playerid, stat[1]-Damage);
    else if(stat[1] == Damage) SetPlayerArmour(playerid, 0);
    else if(stat[1] < Damage && stat[1] > 0)
    {
        new subval = floatround(stat[1])-Damage;
        //takes their armor, subtracts 25 from it. Then it adds that negative number to their health
        //For instance, 15 armor -25 = -10. So we subract 10 basically.
        SetPlayerArmour(playerid, 0);
        SetPlayerHealth(playerid, stat[0]+subval);
    }
    else SetPlayerHealth(playerid, stat[0]-Damage);
    return 1;
}

}

I've got tag mismatch warning at this line

new subval = stat[1]-Damage;

[[ABK]Antonio]

new subval = floatround(stat[1])-Damage;

Wouldn't returning 0 work?

This tutorial does not address the implications of using such a system, if you guys think such a system can be implemented effectively this way think again there is a lot of elements not even shown here that are vital! One issue for instance is such a system will not work correctly if you don't kill the player when they reach less than 50hp. Why is that? Well what happens if there HP is 40 and they get shot by deagle which is 46 damage, they die but the system is configured that they take 30 HP! This kind of system really takes tons and tons of testing to get working nicely it's not as simple as the tutorial would have you believe.

I will update this tutorial in the coming days to address the above problem and any other loopholes mentioned, possibly including armor support. Testing will be slow however because I'm a bit injured. Stay tuned!

A realistic damage should be calculated respect to the caliber of the weapon, velocity of the bullet, body part affected and distance between shooter and target.
Every one of this factors named before can be done (the caliber and velocity can be investigated and the distance can be got by GetPlayerPos and GetPlayerDistanceToPoint) except body part detection that is very inaccurate via scripting.
