We're going to be using him to demonstrate some cool things using ties.

Ties

Ties are connections between bots that can be fired by putting a positive number into .tie.

Tie ID

The number that you put into .tie will be the tie's ID.

If you want to detete a tie, you will need to put the tie's ID into .deltie. If you want to change or fix the angle of a tie, or change or fix it's length, or if you want to feed through a tie or use it to alter another bot's memory values you will need to store the tie's ID into .tienum.

Tiepres

You can readback the value of the last tie created by using *.tiepres. For example:

*.tiepres .tienum store

Will select the last tie created.

Deleting ties

To delete a tie simply store the tie ID into .deltie. Forgotten it? - simply use *.tiepres

*.tiepres .deltie store

Will delete the last tie created.

Deleting the Birth Tie

If you're a combat bot then efficiency counts. You definately don't want to be mucking about with an umbilical cord for the first few cycles of your life.

Combat bot programmers use a neat trick to remove that pesky birth tie.

First, fire a tie at your parent when you are born:

cond
 *.robage 0 =
start
 .tie inc
stop

Since only one tie can exist between two bots this will replace the birth tie.

You can then delete the new tie on the next cycle:

cond
 *.robage 1 =
start
 .deltie inc
stop

Note the use of inc and dec to save energy.

Put an anti-birth tie gene into Animal Minimalis and see how much better he does.

In this forum thread Nums comes up with a few very concise anti-birth tie genes.

Selecting a Tie

The easiest method to select a tie is with:

*.tiepres .tienum store

This will select the most recently formed tie, which is usually the one yo're interested in anyway. It's best to keep in mind though that this will automatically select any tie to your bot, including those accidentally attached by family members.

You can select other, older ties if you remember what "port" they were on. That is, the number you used for .tie.

4 .tie store

will create a tie with port 4.

4 .tienum store

will select a tie with ort 4, whether you made it yourself or not.
