FOSS gamedev and creative worlds

A texturable sun/moon would be nice, and has been discussed before. The result of that discussion was that it would be somewhat non-trivial to do, namely because of the color-shifting that would need to be applied to the two as they rise/set.

I can understand the other functions but not this:

on_blast = func(pos, intensity),
^ intensity: 1.0 = mid range of regular TNT
^ If defined, called when an explosion touches the node, instead of
removing the node

--how to a block NOT explode?
-how to calibrate the power of a explosion
I use TNT PilzAdam, I would like:
-a block does not explode,
-one explode if the explosion occurs at a short distance (1)
-and another block if the distance is greater, however, explodes (2 blocks away)

when I call this function what it does exactly?
where it needs to be made for it to work properly?

Seeking a way to update a formspec.
I will not clog up the engine by calling a function every 0.5sec or less.
Is there a way to enlarge dtime? what I posted does not seem to run.

Just a guess, there might be a better solution.

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

minetest.register_globalstep(function(dtime)
   ifnot time then time = dtime end
   if time >= 10 then
      hello()
      time = 0
   end
   time = time + dtime
end


it works, thanks

I have a question about stairs and slabs. I'm making a birch tree mod, and I need to make stairs and slabs from it. Here is the code I used to add stairs and slabs:


But I get a run error. How do I fix?

The error is caused by a bug in the stable version of stairs. Copy the code in stars and change the prefix "Stairs:" to the prefix for your plugin.

Thanks 0gb.us! :D

Still get a ModError.

I stuck this code inside the same init.lua

What am I doing wrong?

there a way(automatic) to update (refresh) an opened formspec?(without pressing buttons)

Is there any way to catch when a player takes a hit, either from an entity or from another player?

Something like: entity.on_punch = function(self, puncher) ... but for players.

What am I doing wrong?

Nvm, I fixed it.

Now I have another question. Is the function math.random part of minetest?

No, its part of Lua.

I'm getting so close to finishing my birch tree mod. PilzAdam, I used your rubber.lua from your farming mod to generate the trees, make the sapling, leaves, and sapling growth.

Here is the tree growth that seems to cause a problem when I add it to the code.


I get a ModError when I add this to the code. PS. The name of the mod is birch.

Minetest-related functions usually start with... "minetest". 8)

"a ModError" isn't very specific. What is the error?

It says, "ModError: Failed to load and run /home/.minetest/mods/minetest/birch"

I might point out that More Trees already has birches.

I know. Everyone and their brother has told me that already.

Whoops, nevermind, that was a stupid mistake. "llocal" XD

The saplings officially work!

The treegen is working! Now to figure out how to make them less rare...

I need to ask this question to PilzAdam, because he is the one who coded the tree generation.
Here is the code for the generation of birch trees.

Please tell me how to make them less rare.

I tried changing the random, but that didn't seem to help.

So, how do I get the position of an entity?

! attention this is wrong!

type:
self:getpos()

I think you must lower the 100. Just try changing it in 1 or 2 for a quick result.

Edit: teleport to an unloaded chunk or create a new world.
