You can either use:

pawn Код:

if (!sscanf(params, "'heal'f", amount)
{
    // code..
}

but that will not ignore the case of the letters and neither will show the usage for heal option. Another way is this:

PHP код:

    if (isnull(params))
    {
        ShowSyntax(playerid, "/aevent <Option>");
        SCM(playerid, COLOR_SERVER, "Options: {FFFFFF}Heal, Armour, GiveGun, Disarm, Respawn,(Un)Freeze, Repair, Nos");
        return 1;
    }
    if (!strcmp(params, "heal", true, 4))
    {
        new
            Float: amount;
            
        if (sscanf(params[4], "f", amount)) return print("/aevent heal <Value>");
        
        foreach(new i : Player)
        {
            if (FindNear(60.0, playerid, i))
            {
                SetPlayerHealth(i, amount);
                format(strglobal, sizeof(strglobal), "(Admin Event) {FFFFFF}%s set your health to %.1f", GetName(playerid), amount);
                SCM(i, COLOR_LIGHTRED, strglobal);
            }
        }
    }
    else if (!strcmp(params, "armour", true, 6))
    {
        new
            Float: amount;
        if (sscanf(params[6], "f", amount)) return print("/aevent armour <Value>");
        
        // code..
    }
    // rest of them..
    else
    {
        ShowSyntax(playerid, "/aevent <Option>");
        SCM(playerid, COLOR_SERVER, "Options: {FFFFFF}Heal, Armour, GiveGun, Disarm, Respawn,(Un)Freeze, Repair, Nos");
    }
