So I wanted to create a command usable only when the player was standing on a determined sphere. I tried this:

Code: [Select]

function onPlayerCommand( player, cmd, text )
{
if ( cmd == "buy" )
{
if ( ( player.Pos == sphere.Pos ) && ( sphere.ID == 0 ) )
{
Message( "Success!" );
}

else Message( "Error! Not on sphere!" );
}
        return 1;
}Wherever I use the command, it gives me an "getVarInfo: Could not retrieve UserData" error in this line:

Code: [Select]

if ( ( player.Pos == sphere.Pos ) && (sphere.ID == 0 ) )If anyone could help, it would be greatly appreciated.

The error is coming from sphere.Pos. Where did you define sphere?
You'll have to define that using FindSphere.

If you want the function to work for sphere with ID 0 try this:

Code: [Select]

function onPlayerCommand( player, cmd, text )
{
if ( cmd == "buy" )
{
local sphere = FindSphere( 0 );
if ( ( sphere ) && ( player.Pos == sphere.Pos ) ) //Make sure to check if sphere is valid, or you would get errors as well
{
Message( "Success!" );
}
else Message( "Error! Not on sphere!" );
}

return 1;
}

Thanks for helping, the command works now, but wherever I enter it it displays the "Error! Not on sphere!" message. I tried standing on the sphere, out of it, even tried standing on the other sphere I have in the server, but always the Error message.
Correct me if I'm wrong, but maybe it's just too hard to stay at the exact x, y, z position of the sphere center?

Edit: A friend helped me get it working. Here is the fixed script:

Code: [Select]

function onPlayerCommand( player, cmd, text )
{
if ( cmd == "buy" )
{
local mySphere = FindSphere( 0 );
if ( ( mySphere ) && ( GetDistance( mySphere.Pos, player.Pos ) < 4.0 ) )
{
Message( "Success!" );
}
else Message( "Error! Not on sphere!" );
}

return 1;
}Thanks for taking the time to help me though!
