New world spawn locations are sometimes located in a very dangerous place

New world spawn locations are sometimes located in a very dangerous place. I often create new worlds for mod development purposes, and find the Player located in very strange places, such as on top of trees, and the sides of mountains or ice peaks and the like upon joining the world for the first time.

There was once I created a world, and instantly fell to my death in a Jungle Biome off of a tree or bamboo without any user input.

Steps to reproduce:

  1. Create a world with the seed -6523629925161499028

If you need the world save, I can ZIP that up for you as well.

On 1.21 pre1 using seed -349142053501600750 will spawn you at the bottom of a ravine (exactly at 0.0)

I am sure such extraordinary spawn locations weren't so common in the past (this was literally first try)

Can confirm.

I am adding another example of a brand New World setting the world spawn to 0, 0, 0 causing the player to get stuck in the ground and die upon initial world creation.

Using 1.20.4

Seed -3543847026175545133

v1.21

Seed: 8918976068773729218

Player Spawns on small island in middle of ocean... 

Spawns at edge of Lava Pool, next to Ruins with Zombies and Skeletons...

If spawning at nighttime, player is shot at by Skeletons, and knocked into the lava pool and promptly killed.

Player can also unsuspectingly step themselves into Lava Pool if spawning facing away from it and not knowing its there... and first movement step is towards the lava.... which happened to me upon my initial creation of this world and first spawning in... I saw a Zombie start coming towards me, panicked and started moving backwards away from approaching Zombie, and promptly fell into the lava and died... respawn... rinse.  repeat.

Just to be clear about this problem report, the criteria would be if the world spawn location causes a situation where, you as the player, will die without any user input, or take a single step, and potentially die; or even spawn at very dangerous locations that makes no sense for the "I'm just starting to play the game" type of situation; such as on a single block, overlooking a steep alcove, with no other blocks below you; and you as the player, having no tools or blocks yet has literary no way to correct your situation.

The examples attached are good issues, and are adjacent to the problem, of course.

My thoughts are that the Player's world spawn should be on solid ground, with a clearance of around 10-25 blocks surrounding them of more solid ground of at least 5 blocks deep; and not being in a cave; or stuck INSIDE of a wall at  0 0 0, or spawning in mid air/ on Jungle tree's and instantly fall to your death.

So after creating a whole bunch of worlds just by simply clicking on "New World" like 50 times; I'd say there were maybe 2 that would fit this criteria, and a few that were more cheeky like spawning on top of Jungle trees.  Spawning on top of an Oak tree or a Spruce tree; or on a small edge of a small (low) cliff ain't so bad... but when you are around 200 blocks up ...  It can be a problem.  Will attach screen shots of the 3 questionable spawn locations using 1.21.4.

I'd say, your at around 25% top of tree world spawns, and maybe 5-10% sides of cliffs or mountains out of 50-100 new worlds.  Out of those, there might be 2-3 questionable / dangerous world spawn locations. (And a few that were just bizarre, ha)

I believe the world spawning at 0, 0, 0 and suffocating in walls might have been a 1.20.4 bug.

So with my testing for going towards an hour creating worlds ... I assume that you can place this under 1.21.3/4 as well with my results.

The question would be if you guys feel that this is something you want to look into.

Thank you for checking this @unknown , much appreciated!

Obviously, based on various Player experiences; it's always a valid question how much of this is intended behavior or not...

I’ve removed powder snow from this report as it’s covered by MC-239507.
