Minecraft-like R6 Crouching where the player cant fall of an edge of a part

Help and Feedback Scripting Support

Hello, I’m trying to figure out a way to make an R6 crouching script where you can’t fall of the edges of parts. I can’t figure out a way to do this, any help would be appreciated.

You’d need to make a completely custom hitbox for the player, maybe even redesign the player mode first of all.
If the terrain would be round-ish, like roblox’s terrain make the hitbox an cylinder.

#3

No all you have to do is just weld the player to the block if they aren’t touching it

#4

Any examples from both of you of how?

#5

But then they wouldn’t be able to move.

#6

Your best bet would probably be to:

  • Create a custom movement system, which would make it easier for future additions
  • Send raycasts every RenderStepped when crouching, and if there is no part detected under the player then teleport the player back to where they were last frame.
#7

Is there some way for an example or a tutorial on how to do this?
I’m not the best scripter by far.

I have made a self-made movement system but its more of a minecraft “Spectator / Creative” flying thing? Here it is if you want to look at it: My custom roblox game - Roblox

#9

Is this what you’re looking for

#10

Kind of, just instead of him floating in the air, when you’re on the edge of a block you stop while crouching.

#11

Do you have a picture or video clip of what you want to do

#12

Ok, so basically what you have to do is:
Every render step create a variable that consists of two merged vectors, a vector 0,-3.1,0 and a normalized humanoid walk direction velocity vector(excluding the humanoidrootpart Y axis) multiplied by 0.1, then do a raycast from the humanoidroot part to that direction. if there is no raycast result, set the walkspeed to 0, otherwise set it to 16

#13

Sounds like a good idea. I’m not the best scripter, do you have any examples, code source, or step-by-step instructions on how to script this?

Thanks! :smile:

I explained everything. To see how it works in code, just search for individual phrases from my previous post, I would recommend developer.roblox.com and YouTube to do that.

#17

Yes, pretty much. Just only when you’re holding shift.

#18

it works but you have to let go to move in the other direction
works good in first person though

How would I visualize a raycast?
#19

Would this be a local script? if so, just in Workspace?

#20

localscript wont run in workspace, put it in playerstarter scripts or whatever its called as a localscript

I do like it. A bit buggy, but It’s better than nothing.

Also, how would I make those Rays transparent?

Also, also, It did crash my studio once.
