Detection of certain things

[v-rob]

How do I detect these things:

> When the player is fully submerged in water
> Which biome the player is in (in mapgen v6, v7/v5, and valleys)
> When the player falls and impacts water
> What the temperature and humidity is in a biome that the player is in
> When the player is below y=(insert number here) or above y=(insert number here)
> What time it is

I am almost sure that biomes are impossible to detect, but if they are, then great.

Thanks.

EDIT: Also, is it possible to detect which map generator you're using?

1. Simple check of node at playerpos.
2. Impossible. The best you can do is detecting the surface nodes.
3. No idea how to do that one may be hard and laggy.
4. There's a temperature mod somewhere, it does that job just fine.
5. check of player pos
6. minetest.get_time_of_day()

7. I saw it was possible, idk how though.

'Get temperature / humidity at point' and 'get biome at point' are coming (my jobs).

Good luck. You'll need that.
