Weapon/Item Level Restriction

[Miks]

Is there a way to to restrict items (primarily weapons) to a certain level. The problem is I dont want the lower down levels i.e newbs to be able to purchase the high powered weapons.

Is there an easy way to add level restrictions to the item creation page?

[KyleMassacre]

Sure there is, its similar to what is done for cities. I have something similar but instead of level i use player class. The only thing is that they are able to purchase the weapon it just does not allow them to use it

[sniko]

• New database column in `items`
  
• Edit the staff items to show another form entry for the minimal level
  
• Edit the queries in staff items
  
• Do a binary-like check in equip item IF ( [weapon_minimum_level] > [my_level] ) DISPLAY "Can't equip. Level up!" END IF
  

[Miks]

Ok I have tried to edit equip_weapon.php but I need some help as I'm not a coder.

I get this error "Parse error: syntax error, unexpected T_ELSE "

$plevel=($r['level']);

if ($ir['wlevel'] > $plevel);

{

echo "Can't equip. Level up!";

}

else ($ir[$_POST['type']] > 0);

{

item_add($userid, $ir[$_POST['type']], 1);

}

item_remove($userid, $r['itmid'], 1);

$db->query(

"UPDATE `users`

SET `{$_POST['type']}` = {$r['itmid']}

WHERE `userid` = {$userid}");

echo "Item {$r['itmname']} equipped successfully.";

I have updated the item table and added a new field called wlevel. Just cant get this part to work.

Try something like this:

if (isset($_POST['type']))
{
   if (!in_array($_POST['type'], array("equip_primary", "equip_secondary"),
           true))
   {
       echo "This slot ID is not valid.";
       $h->endpage();
       exit;
   }
   else if ($r['wlevel'] > $ir['level'])
   {
   	echo "You are not at a high enough level to equip this.";
       $h->endpage();
       exit;
   }
   if ($ir[$_POST['type']] > 0)
   {
       item_add($userid, $ir[$_POST['type']], 1);
   }
   item_remove($userid, $r['itmid'], 1);

 

cause i believe your statements went a little something like this:

if

else

else

else if works great in between an if and else statement

My error has now disappeared but the script ignores the level restriction command and equips the weapons. I have a weapon set to wlevel 8 and my level is 4 but instead of throwing back "You are not at a high enough level to equip this" it stills assigns the weapon.

[KyleMassacre]

change my else if to if and see if that works

p.s. use [*code*] tags [/*code*] without the stars

[Miks]

Hi KyleMassacre,

Thanks for the tip.

I tried replace the else if with just if and it was producing the same results, its like its bypassing the level restriction......

[Miks]

It works!!

I had to replce

else if ($r['wlevel'] > $ir['level'])

with

else if ($r['wlevel'] < $ir['level'])

[Miks]

Sorry I mean

I had to replce

if ($r['wlevel'] > $ir['level'])

with

if ($r['wlevel'] < $ir['level'])

[Miks]

Hopefully its the final post but I had to alter the above code and replace it with

if ($r['wlevel'] >= $ir['level'])

{

echo "You are not at a high enough level to equip this.";

$h->endpage();

exit;

}

As far as I am aware it is working correctly now

[lucky3809]

I will tell you what I would do for this...

In items table create a new field called restrict and make it ENUM On,Off

Then update your item staff page and add that options, so when making an item you can decide if you want that weapon to be restricted to new players or older...

Then add something along the lines in check level part ... if($ir['level'] > 10){ UPDATE FIELD TO OFF IF IT IS ON }

That may work fine. Try equipping an item you can equip though just to be sure

Sounds way to complicated haha

[Miks]

I can get the script to work like this which isnt correct.

If you're higher than the weapon level you cant have the weapon, but when the weapon level is higher than your level it works.

I know its a case of changing the bracket to ">" but weirdly it doesnt work like that but does work "<"

if (isset($_POST['type']))

{

if (!in_array($_POST['type'], array("equip_primary", "equip_secondary"),

true))

{

echo "This slot ID is not valid.";

$h->endpage();

exit;

}

if ($r['wlevel'] > $ir['level'])

{

echo "You are not at a high enough level to equip this.";

$h->endpage();

exit;

}

if ($ir[$_POST['type']] > 0)

{

item_add($userid, $ir[$_POST['type']], 1);

}

item_remove($userid, $r['itmid'], 1);

$db->query(

"UPDATE `users`

SET `{$_POST['type']}` = {$r['itmid']}

WHERE `userid` = {$userid}");

echo "Item {$r['itmname']} equipped successfully.";

The above is how it should be but doesnt work.

if (isset($_POST['type']))

{

if (!in_array($_POST['type'], array("equip_primary", "equip_secondary"),

true))

{

echo "This slot ID is not valid.";

$h->endpage();

exit;

}

if ($r['wlevel'] < $ir['level'])

{

echo "You are not at a high enough level to equip this.";

$h->endpage();

exit;

}

if ($ir[$_POST['type']] > 0)

{

item_add($userid, $ir[$_POST['type']], 1);

}

item_remove($userid, $r['itmid'], 1);

$db->query(

"UPDATE `users`

SET `{$_POST['type']}` = {$r['itmid']}

WHERE `userid` = {$userid}");

echo "Item {$r['itmname']} equipped successfully.";

But when the bracket is round the wrong way it does work but not how I want it.

 

Hope that made sense, any further help is greatly appreciated!!

[Someone]

Apparently $ir['level'] is for some reason never higher than $r['wlevel']

I suspect there is something wrong with one of the variables.

echo 'if ('.$r['wlevel'].' < '.$ir['level'].')'; // should show clearly if there is anything wrong with the vars
if ($r['wlevel'] < $ir['level'])
{
echo "You are not at a high enough level to equip this.";
$h->endpage();
exit;
}

[Miks]

@1331

I added the line as you suggest i.e

echo 'if ('.$r['wlevel'].' > '.$ir['level'].')';

if ($r['wlevel'] > $ir['level'])

{

echo "You are not at a high enough level to equip this.<br><a href='inventory.php'> Return to inventory</a>";

$h->endpage();

exit;

}

The result was

if ( > 4)Item Chainsaw equipped successfully.

Return to inventory

The weapon level I am testing this on is 12 and my level is 4.

[Someone]

As you can see from the output, the variable $r['wlevel'] is not set properly, its blank. And therefore always less than 4.

There correct echoed result then be should be:

if (12 > 4)Item Chainsaw equipped successfully.

You need to backtrack to where $r['wlevel'] is suppose to be set, $r is usually a query result, search your code for $r =

Most likely you will find a query of some sort.

$db->query("SELECT * FROM ... WHERE")

or mysql_query("SELECT * FROM ... WHERE");

Either add a or die(mysql_error()) to the query, or echo out whats between the " "

then run that in phpmyadmin

I have not touched mccodes in years, dont recall exactly how that system is built.

EDIT:

You can also do a

print_r($r);

To see if the data has been retrieved correctly from the database
