Are you using R15 or R6 for testing? It looks like you should be able to climb it.
It’s hard to gauge your part sizes through the picture but I typically use 1 stud gap between each part in ladders and have no issue with climbing. If for some reason its still not working you could try to use invisible truss parts as annoying as that may be.
If you wanna have a ladder like that, then do what most people say to just move the parts slightly closer, but maybe add a truss and make it invisible. Hope this helps.
You should always be using Truss parts if you want your players to reliably prompt the Climb animation. As suggested above, turn CanCollide and CanTouch off for the actual steps, and make the Truss parts Transparency = 1.
Any other method is (at least partly) unreliable.
This is not true lol. R15 has variable scale (based on hip height) - it’s one of its major features. This makes ladders and stairs just as variable. Roblox’s “normal avatar size” was defined by the R6 rig, and physics calculations are based off that scale too (at least, they used to be, not sure if they still are?). In short - Climbing is not restricted to only R15 rig types.
How large is the gap between parts? If they are too close, they will be registered as a wall; if they are too far apart, they will be registered as a bunch of walls. I would recommend about 1 stud between the parts.
@Aotrou’s point is also very valid.
Ohhhh thank you!
But the thing is, we used that technique to make the ladder work and it did, but we have a script for the ladder (when you press button the ladder appears). So if we use 2 trusses, we will have to modify the whole script since we cannot make trusses wider nor union them
I mean it’s either that or follow what many people are saying above: you need to make your ladder rung spacing 1 stud (or slightly less if I remember correctly?). But again, this isn’t great practice, and is unreliable.
I don’t know your specific situation or use case though, so you’re going to have to test multiple configurations yourself. We can only help so much 
Don’t union a simple ladder, that’s something that’ll make it harder to climb and make your game laggier depending on how many things you’re unioning.
It could be your Climbing animation, if not move them closer to eachother!
Make the blocks closer so players can climb.
If the Player can’t climb up it then make the blocks smaller.
Put an invisible Truss part over it to make it easier for yourself.
Here could be some issues that could be happening
• It’s not lined up straight
• It’s too long
• It’s not close enough to climb up
• Or the brick’s are too thick!
Here is your problem
Here’s what my picture is
Here is yours.
Do you see the difference?
Your ladder is not close enough for a player to climb and it’s probably too long. Try making it shorter and a little closer because i’ve tested this by making my own and it worked! Also, did you happen to use a bloxy player to test this? Because maybe it may not be able to climb that type of ladder.
If you put it closer you can. (the truss closer to the handmade ladder)
What it looks like if you do it properly:
Just turn the cancollide for the handmade ladder to off and turn the truss cancollide to true and make the truss invisible
R6 was the only character type when climbing was added, so if anything R15 would be worse for climbing since it was added after climbing already existed.
Did you anchor the truss, it seems you may have not causing the bug.
Ohh ok! I didn’t think that would work properly.
is the ladder unioned? that was the problem for me
Make a truss inside and make it invisible
