More than 32 Tags

[hwills]

Hello!

I was hoping to modify the amount of tags from 32 to 100, and I saw this thread:

Having more than 32 tags and large ennemies

Hi I'm making an rts/tower defense. I need to tag overlaping zone. For example there is zone near tower and road zone. Some monsters avoid tower, other don't. Sometimes a road overlap a tower range zone. The solution I use is to use one bit of the tag to register each type of zone. For example a zone with tag in binarie 01 is road, a zone with tag 10 is near a tower, and a zone with a road and near a tower is 11. I then give for each monster a penaltie for each kind of tag it react. It works,…

But I’m not sure how to modify the bit-packing line of code in the graphnode.cs to create more tags. Is there any other way to do this or a guide in your documentation?

Thanks so much!

Hi

To get lots of tags you can do this change

public uint Tag {
    get {
        return (flags & FlagsTagMask) >> FlagsTagOffset;
    }
    set {
        flags = flags & ~FlagsTagMask | value << FlagsTagOffset;
    }
}

to

public uint Tag { get; set; }

That will give you 2^32 tags or 4294967296 which should be enough.

Note however that with this change, tags will no longer be saved with the node data if you are saving graphs to file or using cached startup. However if you are not using that, or the tags are all just zero when you do, everything should be fine.

That worked, thanks so much!
