Hatches would line up with top layer of a block and open downward instead of the bottom layer and open upward thus making you able to walk on them as a flat surface, and they double has a ladder due to you needing to remove a ladder to place it.
As hatches have holes in them it wouldn't be to farfetched to have them be climbable too.
Hatches also maybe place so they line up with bottom layer and open upward (as they currently are) for when they are used for roofs such as for attics aswell as double as a ladder.
Suggested by @assassin10:
To avoid ruining mob and player traps they could could only be climbable if there is a ladder above or below it.
Suggested by @Failcrafter:
Reduce the hit box of the hatches (AKA reduce the size to = ladders) and they should anchor to the edge of the block that the player is closest to, like doors.
I make a new world, and put hatches on top of my spawning point,caves under that, and gonna make a base there.
Now I'm interested how it is about (like doors, you need to put them in from outside, to make more secure inside)
I put the hatch in from outside, but i like it to be on top, not one block down.
How do i think there, is it better to put that in from below, think that way the hatch gonna be on top.
Any problems with mobs that way ?
Picture, don't see the right side, i haven't time to fix anything in that new world. maybe no problem, i gonna put in that hatch from below instead and all is fine.
I have a ladder up to that hatch, and easy going up thru , but i have to jump the last bit , one block up, no problem with that, only esthetic i like the hatch to be on top.
Um can you speak proper English?? I had a hard time reading that because i had to try and make it make sense.
While still really cool, hatches do need some improving.
I think an open hatch should have a reduced hitbox or imbed itself a little into its anchor block. It's a little hard to descend into a hole with both the hatch and a ladder in the way. I agree that hatches should be climbable, but only if there's a ladder under it.
The main fix I think they need is their placement. They should anchor to the edge of the block that the player is closest to, like doors. This would allow for hatches that open upwards and trapdoors that open downwards. Maybe even half-doors too.
That would be awesome. I can't really make traps when the hatches pop up like they do.
But since people have already made things with the current hatches, what if there were iron hatches that opened downwards in addition to the current hatches?
The only real problem with downwards-opening hatches is that they would be tricky to power with redstone.
