[1.12.2] How to make the player sleep

[That_Martin_Guy]

I am not asking how you make the player able sleep on your own bed/block, but rather how to make him sleep anywhere. Setting the spawnpoint isn't necessary, just making the player "fall over", have his screen fade to black etc. I think it'd be super unnecssary to create my own method to make the player do this, but I cannot find any other sleep related method besides trySleep in EntityPlayer, but it only allows him to sleep if the block at the specified position is an actual bed. Any ideas?

You would need to find a way to remove that check.

How would I remove something that's part of vanilla code?

[Draco18s]

Generally...you don't

[That_Martin_Guy]

I know you're implying something, but can you please just explain what it is? Telling me what not to do even though I already knew about it (?) isn't really helping...

You have two three options:

1) Find a way to replace the object that the code is in with your own version of that class. Doing this ranges from medium difficult to almost impossible, depending on the object in question.

2) Core mods, which are heavily discouraged. Do not do this, do not ask for help doing this. If you do not know how to do this no one will tell you.

3) Make a pull request to Forge to insert some kind of event or other modification that will allow a mod to hook into the behavior and override the vanilla mechanic. Then wait six to eight weeks for your PR to get approved.

Core mods don't seem like an option, and I don't think I'd find a way to create a hook for this certain scenario that would benefit anyone other than me and would therefore not be accepted.

That leaves this option. But the method I'm looking for is in EntityPlayer, and I doubt I could override that in a good way without breaking things. So is there any solution here?

There is a small chance that you would be able to copy the method to your own class and change it to edit the player externally.

I'd do this if I could, but a lot of the things that are done in the method are changing private/protected variables which I do not have access to. I suppose I could in a worst case scenario I could change them with reflection.

Unfortunately, not for this. If you try to set the player sleeping, they'll unsleep the next time the update code runs, popping them out of the sleeping state in a way that you (as a modder) can't cancel.

You can replace EntityPlayer with a new subclass, but you are correct that it could break things (e.g. conflict with other mods that also replace EntityPlayer, like Galacticraft). There is no way around this, beyond the previously mentioned alternatives.

Possibly you can bookend the player tick event, in the Pre stage record the stuff that is necessary, then undo anything the standard tick does. Also there are probably a couple events related to beds and sleeping that might need handling.

 

Basically Draco18s is saying you need to root through the the code and figure out clever ways to intercept each behavior. Sometimes it is surprisingly easy, sometimes almost impossible. Also depends on your java confidence.
