How do you add nodes to a group if they already exist?

How do you add nodes to a group if they already exist?

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

   local data = minetest.registered_items[item]
   local g = {}
   if data.groups then
      for k, v in pairs(data.groups) do
         g[k] = v
      end
   end
   g["group_name"] = 1
   minetest.override_item(item, {groups = g})


WTFPL, for you.

Just add "static_spawnpoint = 0,0,0" to your mintest.conf

Hello Don... thanks, I tried this but it did not work. Each user spawned in a different point.

How do people that run servers to set the spawn point?

Also, why users can kill each other if I disabled Damage?

thanks again

the static_spawnpoint started working after a couple of reboots on the pc.

I still need to know how to disable users killing each other....
thanks

Maybe try upgrading. These are things that should just work. It is strange that they don't.

In minetest.conf you'll find this option:

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

#    Whether to enable players killing each other
#enable_pvp = true

Modify it to:

Code: Select all

#    Whether to enable players killing each other
enable_pvp = false

If Formspec has been removed by death, what is returned?

Is there a way to get the time from the last use of a tool in on_use? I want to make a tool that needs a cool down before it can be used again. I know, I could use minetest.get_us_time() and compare it with a saved value, but is there an easier way?

Is there any explanation of formspecs that doesn't leave you more confused then before?

Can I set a value via chat command for a block to use as a teleport point when a player is stood inside?

Sure. Store it in the metadata of the tool's ItemStack (the metadata for an ItemStack is just a string, so you might need to serialize things that don't have a simple string representation).

That is what I described. So I have to store the time of the last use and compare them with the current time.
I was thinking, there could be an easier way because the normal damage handling uses the full_punch_interval to influence the amount of damage.

Unfortunately damage is completely handled by the engine, with almost zero control or visibility from Lua. You can set damage properties when you register the tool, and that's basically it. You also can't partially override the functionality or add to it. If you do, the default damage mechanism is lost.

That's sad to hear, but it was suspected. I did barely hope there was an easy way.
Thank you, anyway.

Can someone give me an example of how to use NodeMetaRef ?
E.g. if I have a node which holds a value caled test... ?
Didn't understand the article in the devWiki.

Hello!

I made a simple wodden bridge, several nodes long, using nodebox. Works fine with 3 nodes in lenght, but when i increase the size to 4 nodes i fall through the 4th node.
I used multiple nodes in lenght to have some variation in the planks size (as shown in the attached image).

Or is it possible to create multible nodebox models and pick a random one on build? My workaround so far was to create multiple nodes with some variations and cycle through them with crafting (e.g. bridge1 in hte crafting window turns into bridge2, bridge2 into bridge3, and bridge3 into bridge1 again).

Thanks for any help!

there's another bridges mod viewtopic.php?id=3488

Thanks, looks nice.
However, didn't answer my questions tho: Why do i fall through the 4th node of my bridge, and can i place nodebox blocks randomly selected from a list? My goal is to create variations in the pattern of the bridge without the need for crafting and placing multiple nodes (which would work fine, so does the 3 node bridge).

I am working on updating mydeck. I want to make the stain brush wear out but I have not done much with tools. I am not sure how to do this.

What would be the best way to make it wear out?

Take a look at the screwdriver mod:
https://github.com/minetest/minetest_ga ... it.lua#L81

Also you probably should probably check only once for the wielditem and not for every node. So, there is one if with the wielditem check that is around the other checks. (Hope this is clear)
Maybe you should consider using minetest.register_tool and using the on_use callback. Then you can omit the check for the wielditem.

[Don]

Thank you. I will do that.
I appreciate your suggestion and welcome any other suggestions or comments you may have.
