Regular Ties don't form with vision disabled 2.45.01

(1/4) > >>

Tilthanseco:
For some reason, I can't get regular ties to form when the bot's vision is disabled. In version 2.45.01

Attached is a save featuring different tie forming bots, none of them will form permanent ties.

ikke:
Are they really linked to vision?

Botsareus:
That's because the robot must "see" the robot it is trying to tie to. example: If you have six robots around you, you will only tie to one.

i.e. Yes ikke they are.

Tilthanseco:
I thought it was a bug because a bot does not necessary need to know there is a bot in front of it to tie to it. I found this while testing my blind bot against the bots posted here: http://forum.darwinbots.com/index.php/topic,3549.0.html (The blind bot challenge).

The 2 blind bots here work by firing ties randomly and sharing energy. They don't make any reference to eyes so they should be able to work with vision disabled.
In fact, most of the ref values can be used with touch now and still work with vision disabled.

This limitation or bug makes it more difficult for blind bots to evolve with vision disabled because they can't be multy bots or use tie feeding.

Therefore I think it is a bug and should not be by design.

P.S. The ties I am referring to are the ties initiated by bots, not the birth tie. The birth tie does indeed form with vision disabled.

maybe a fix could be:

While there is a birth tie and vision is disabled, the robot could see it's parent. What do people think?

Okay, this explains why my feeble attempts at creating a multibot didn't work
