# Problem with tag assignment

Hi,

When I try to assign the tag value 34 (32 +2) to my node, the get value is not the same as the set value.
I get 2.

Any help ?

Hi

The package only supports 32 tags.

If you really need more of them you could make a change to GraphNode.cs, change the property that looks like

/** Node tag.
* \see \ref tags
*/
public uint Tag {
get {
return (flags & FlagsTagMask) >> FlagsTagOffset;
}
set {
flags = flags & ~FlagsTagMask | value << FlagsTagOffset;
}
}


to

public uint Tag {get; set;}


and you will get a lot more tags to use.
This will however make tags be ignored when saving graphs to a file, however if you don’t use that feature it should work fine.

I have 6 tags now :

1. Ground
2. Player1
3. Player2
4. Player3
5. Player4

I want to add to my tag node the tag player1 and road.
So 1<<1 | 1<< 5 = 2 + 32.
And the 32 value is not taken

I have doing something wrong ?

Hi

A node can only have a single tag at a time, you can use them as bitmasks I suppose, but the package has no knowledge of multiple tags on a single node.

Oh any reason for not support that ?
Tag system is very good for manage complexe communication with A* and AI logic.

Can you consider introducing it ?

Mostly because of additional complexity and memory usage that veery few people will use.

Ok I will change my logic so.

Thanks
