If it's nothing new, could someone show me the links to the glitch I described? I looked at snapper loading described in sage's links and it isn't the same thing, mine is only using a horizontal motor and an extender, and I'm making a chained horizontal motor with the 2nd motor stacked INSIDE of the 1st motor. No snapper at all. I also tried to look everywhere for horizontal axle loading and couldn't find it, even on the beetlebros site did it describe it as working for VERTICAL motors. my method only takes 3 or 4 motors to spin the axle out as well, so once again if someone could point me to a place describing this method I would be grateful. Thanks.

Motors can be axle loaded fom any position. You are saying something like:

"If you do a hanstand with an egg in your shorts something other than gravity makes you stick to the floor."

Post by: tankcat on April 10, 2009, 03:08:42 PM
Alright, even if the same can be achieved with conventional axle loading, using the pause/break button method can snap the axle out of the motor in 3 to 4 tries. I'm not saying it's completely new, but it's a lot more convenient. I mean it's basically super axle loading, because you are pausing IMMEDIATELY, rather than the 1 second it takes to move your mouse to another view.

**And I wasn't aware that axle loading could be done from any position, I couldn't get enough momentum to snap it out of the motor horizontally, it only worked for me as described in the video on the beetlebros site. I mean it's not like I'm coming out of nowhere with this, I searched around to make sure I'm not duplicating something else and I'm not. I've never seen anyone using this pause/break method.

Post by: Trovaner on April 10, 2009, 08:21:37 PM
Since your first post doesn't say anything anymore, I'll comment on the comments...

The first thing is that your not the first to use the Pause button while performing something similar to axle loading. You can take a look at the date of the video I have on youtube for proof of that or just look at my ra2wiki page and see when it was added. I originally posted it on the old forums along with some other minor tips for other glitches.

The axle loading glitch is anything that removes the axle/pivot of a component by changing tabs to build up speed.

That being said, I wouldn't mind seeing a vid or pic or description of how you did your glitch.

Edit: I didn't read the entire thread so I just saw your small description and it sounds like something I showed Starcore a while back for a bot that I wanted to add to his pack. It basically had a motor connected to 2 or 3 extenders with 1 or 2 of them using the side attachment point to connect to the side attachment point of the previous extender (like seen for some weapon designs) and then it had another motor attached to the end going into the first motor (after axle loading the first of course). Is that how you did yours?
Title: I found a new building technique/glitch
Post by: tankcat on April 10, 2009, 10:52:22 PM
I'm sorry guys, I had to leave for a while. Yes, Trovaner seemed to describe it correctly. Basically using the pause button I was able to increase the effects of axle loading.

The two motors are chained together, connected to each other and inside each other. Here is a picture of the end result:

(http://i39.tinypic.com/2ljjo1v.png)

The two motors are chained together, with that being the end result. I've tried it with other multiple motors, and it's much easier to do than conventional axle loading.

EDIT: Here is the video from the previous post, I uploaded it to mediafire: http://www.mediafire.com/download.php?kmkz3umnywh

Yes, they are incredibly easy to stack that way. That literally took me 30 seconds to implement after I got the hang of the glitch.

I'll try, I've been experimenting with ways to implement it using horizontal motors, I like making horizontal spinners the best. So far I haven't seen any results that are quite up to par with something like 3 motors with 3 rotators and 18 maces on the end, but it's getting there.

*Alright, I was testing the bot on sentinel and hit with 3507 damage. Bot only weighs 557.4kg. Here's a picture:

Post by: Naryar on April 11, 2009, 01:22:38 PM
That is nothing close to a new glitch.

That's classical axle loading with Click's "add and remove motors" method (that i find long as heck when you can axle load by changing tabs or simply adding/removing extenders on your motor, and i got a video of it here: http://www.youtube.com/watch?v=ReAplF1sq4g&feature=channel_page).

However, that's a new way to chain 2 HPZ's and i find it very convenient because it's compact (unlike the classic method) and saves weight. Nice find.

And i just found another setup that can make that thing even more compact... with 1 extender less

EDIT: Fritzl looks very nice.

I tried your extenders axle loading glitch, and you're right it's much better implemented and easier when you're out of space. I just assumed that what was on the beetlebros building technique site were the only techniques that had been discovered. I agree, classical axle loading is extremely long and not worth it, and I couldn't get it working for my horizontal motor. But using the pause button let me stop the game instantly after adding a red motor, letting me build up enough momentum to pull the axle out after adding 3 or 4 motors.  But, your extender glitch is a lot more convenient.

Also you found another setup that is even more compact? A chained motor setup? If you wouldn't mind, it'd be great to see what you've come up with.

And everyone should join moonbear's hamachi server, he made a bot that makes small children cry. No one has beat it yet.

EDIT: Here is a better picture of fritzl, I have the two motors connected to one motor, I find it does a lot of damage.

I found an even better way to stack chained motors, using only 2 extenders. This chain motor uses a 40cm extender and a "T" extender, matches up perfectly.

True, but something I find is that if you have too many layers of components, it limits you.

With that design you can add more to the motors, like so:

(http://i41.tinypic.com/a0uds5.jpg)

With one less connector, that leaves room for one more layer, which I was able to use with the Y connector to add 2 maces to each arm, instead of 1.

If I'm right it's 3 extenders set up to make an equilateral triangle. In other words 60 degrees between each of the extenders, using the attachment points on the side.

That'd work too, however I think he's only using 2 extenders somehow... the closest I got to that was with a T connector.

You can, but they won't stack very well. Usefull if you have problem with the rule of 7, but can be a problem if you want to make it invertible.
Title: I found a new building technique/glitch
Post by: ianh05 on April 12, 2009, 12:55:32 AM
the pics i see have extenders coming up then one coming off the end of it, I'm suggesting that they use the side and get the 2nd motor to go down into the first one.

that would allow you to use more weapons (2 weapons on each extender coming from the tribar).

Post by: somestrangeguy on April 12, 2009, 07:51:19 AM
@SB: There is already a vid on page 3.

Here is what I made, I decided to go straight for 2 motors. Its a little shaky but it doesnt start gyrodancing until it has lost most of the weapons. Also this is very underweight as I was making it a HW, it weights 530.6.
How I put this together?
HPZ-tec-> T Extender -> 1 20cm round extender downwards from both ends -> HPZ-tec on both extenders -> Tribars -> Extenders on all ends -> 3 maces/extender on the tribars.
(btw, this is the first time I used maces on a HS)

Battleshot is VS SCv4 Predator, you cant see him in the pic because the final hit threw me away from him so fast that I couldnt get him in the picture.

Going to submit that to Starcore for Sentinel Observer SCv4 - after some more tweaking though, and maybe another version, cause it can't self right nor is invertible.

Calm down! Im going to take screenshots from the vid and post them here.
Edit: Actually, im going to take screenshots from the game, the pictures were not good quality when taken from the vid.

First, Place 20CM extender and T Extender like this:
(https://gametechmods.com/uploads/images/4919Glitch1.PNG)

Then axle load the motor off and hover a 40CM like this, spin the motor and then attach:
(https://gametechmods.com/uploads/images/56781Glitch2.PNG)

Attach a HP Z-Tec and some weapons on it:
(https://gametechmods.com/uploads/images/36276Glitch3.PNG)
(https://gametechmods.com/uploads/images/28036Glitch4.PNG)

Garage and back, and you should have this:
(https://gametechmods.com/uploads/images/71536Glitch5.PNG)
(https://gametechmods.com/uploads/images/91431Glitch6.PNG)
I think I did something wrong because this isnt as centered as I have seen...

The vid is exactly the same. but it only uses 3 20CM extenders and the setup is less favorable if you are going for invertibility.

Yes, the 3 20CM setup is less favorable, however there is a setup using only a 40cm extender and T extender that is more desirable AND more invertible:

I have pictures to show the setup in order:

1. Swing the extender out using axle load glitch:
(http://bayimg.com/image/capldaabg.jpg)
2. Delete 40cm extender and then add 40cm extender to swing it out of the bot:
(http://bayimg.com/image/capleaabg.jpg)
3. Make sure your extender it outside of the bot, like so:
(http://bayimg.com/image/caplfaabg.jpg)
4. Add "T" extender using effe glitch to give yourself enough room to add a motor:
(http://bayimg.com/image/caplgaabg.jpg)
5. Finished setup, very compact:
(http://bayimg.com/image/capliaabg.jpg)

That's pretty much everything. Make sure to attach the T extender using the effe glitch to give you enough room to add your motor. I find this setup to be the best, as it is most compact, completely centered, AND uses 2 extenders, opening up another "rule of 7" layer for weapons. Also, I would've replied sooner if I had known you had trouble viewing the video. I haven't really been checking the thread.
