Bitwise Operations gone wrong?

[James]

[lua]
function _R.Player:GivePermission( name )
local p = self:GetPData( "Perm" );
local a = Permissions[ name ][ 3 ];
local flags = p | a
self:SetPData( "Perm" , flags )
print( flags )
print( self:GetPData( "Perm" ) )
end

CreatePermission( "Admin" , "lol" )
CreatePermission( "VIP" , "lol" )
CreatePermission( "Mod" , "lol" )
CreatePermission( "SuperAdmin" , "lol" )
CreatePermission( "Owner" , "lol" )
[/lua]

outputs :

] lua_run print( Entity(1):GivePermission( "Owner" ) )
> print( Entity(1):GivePermission( "Owner" ) )...
1[Perm]
1[Perm]

wtf?

Did you print p and a?

Line 4 and 6 is the answer to your question :toad:

Isnt | the bitwise or operator, so of course it will be the same.

try & instead.

If you want to add flags you should use bitwise or.

And should be used when checking for flags.

GetPData returns a string, which is probably what's screwing this up, though I'm not sure why it's not throwing the standard "attempt to perform arithmetic on a string value" error.

Regardless, tonumber(self:GetPData( "Perm" )) will probably help here.

Ok Thanks ;) Seems logical your response mrflippy, I will try that now

Nope :/

( the names are Owner and Admin and what ever because i didnt have any inspiration for other names. Im not actually going to use it as a permissions mod for administration )

the # operater doesnt work on tables with string indexs? needs fixing

[Wizard of Ass]

# returns the highest numeric index of a table.

You also have the parameters to math.pow switched around. You want 2^x, not x^2
