Ladder Help

Archive: 5 posts


I'm making a remake of Blaster Master (old NES game) and it uses ladders to climb up and down in some spots (this is for Sackboy). I have done the layer switching ladder before. Would really rather stay away from this.

I woke up this morning with an epiphany. OMG, just use a grabbable hologram attached to a piston. Actually the original idea was an invisible controllinator on a piece of in a track in the wall that moves up and down the wall. That idea fell through because the wall isn't on both sides of the ladder all the way down, and an invisible controllinator would make Sackboy invisible anyway.

When I did the hologram/piston idea it worked however, because there's no wall next to the ladder for the whole thing, going down was pretty smooth but coming back up crushed Sackboy in between the wall and the hologram's floor (invisible rubber). I put the floor so that you don't just fall down the ladder shaft when you walk over it.

It's a really long ladder and there's no other way back up, so if he falls through he has to be able to get up via the ladder.

I noticed Makotoi had a cool ladder in his L4D level. I think his username here is Shadowriver? That works pretty well and I have no idea how it was made, because you hold R2 on the ladder AND THEN press up or down to scale it. I wasn't aware you could be able to have the analog stick control stuff simply by grabbing something. and grabbing with R2?

He did use a sackbot though so that could be it. I'd rather not use a sackbot if possible. I mean, can you control a sackbot controlling a vehicle? (controllinator nesting)

Thanks for the help guys!

I mean, can you control a sackbot controlling a vehicle?

I'm pretty sure that you can do this.

There are 2 ways to have R2 control something - by using a sackbot, OR having a remote control controllinator.

Here's how I'd do it (without sackbots):

- Put a controllinator on a piece of holographic material, set it to receive wirelessly from nearest player, and make it invisible.
- Put a gyro and an anti-gravity tweaker on the holo
- Put a follower on the controllinator, and only allow it to move up and down. It should follow the player.
- Put a material tweaker to make the holo grabbable.
- You'll need to have a solid piece of material attached to the holo, but I would put it in a different layer rather than at the base. Perhaps in the layer behind the ladder (make the ladder in the thin layer and the holo and other material thick)
- Now attach a grab sensor to the controllinator and connect it to a NOT gate, and then to the follower.
- Connect the up/down stick on the controllinator to an AND gate and connect the grab sensor to the other input.
- Connect the output of the AND to a direction splitter
- Connect the up (positive) direction to turn on a mover that moves up
- Connect the down (negative) direction to turn on a mover that moves down

Hm. Can a follower be set to move only up/down? I'll have to check that out. I am at work atm. This morning when I did it I looked at setting a Sackbot to follow the player but only move up/down but didn't look at the follower. The Sackbot has a boolean setting "allow up/down movement" but not allow left/right movement.

I am not completely opposed to using Sackbots. It just seems like an extra layer of complexity. I'm already going to use them for the top/down portions by having Sackboy press up to enter the little huts with a controllinator inside with auto-activate turned on same layer only.

Thanks for this, I'll try it when I get home. Is there some reason why an advanced mover wouldn't work in this situation?

Followers can be set to move only up/down - but you need to DISABLE up/down movement and then ROTATE the follower 90 degrees (so that up/down becomes left/right).

The reason I said to use two movers is because the AND gate behaves funny with controllinator outputs - the direction can flip when you press the stick just a little bit. You can use an advanced mover if you first use a direction splitter, then AND gates, and then a direction combiner.

YES I know exactly what you mean by the AND gate having problems with controllinator output. I think it has something to do with the AND gate functioning as a min/max function like Rtm said in his blog post. I can't remember which one does min and which one does max.

You forgot to mention flipping the follower on its side I tried this though and was having some problems with it. For now I opted for the alternating layer ladder.

What happened was, well. The ladder hole is one big grid square wide, and I made the backing material in the thin layer, one big grid square wide and it doesn't smoothly slide through. and when it exits the hole it doesn't go back in properly (which is normally NOT a problem ever haha) but I definitely see why. I shaved off the sides and then it was better but without the follower it was kind of wonky.

I'm thinking that now with this new info I believe it should work better. I'll try it again.

Oh, btw. The way I solved the advanced mover issue is I put the output of the AND gate to the on/off input of the advanced mover and just put the up/down Controllinator output directly into the up/down input of the advanced mover. Thoughts?
