I want the player to have 100hp instead of 20
So how could I increase players maxhp to 100?

Afaik it is not possible because it is hard coded in the core. But maybe I am wrong. I also would like to change the hp

Yes, it's hardcoded.

Problem bypass idea: Use armor to protect you against damage.

Well, than you can modify it in the source code and compile it. But this would only work on your server, so I wouldn't recommend it

There is an old feature request for this:

Here's an issue on GitHub:

For some reason, it is labelled “Low priority”. :-(

hmm, there should simply be a way to replace the default health with another type of health system to extend HP (3D-Armors is a good example)...

It's possible to create something like that with the existing minetest modding API, however you may need to add few variables and integrate it together to work with the max health variable if the additional health value reaches less than or equal to the default max HP value.
