I would also like to know the version number when [colorize was added, ie was it before or after the release of 0.4.11?

https://github.com/minetest/minetest/co ... c/tile.cpp
ctrl+f can help you (if you use firefox)

Ah, so not part of current 'stable' then, thanks.

I still would like to know what 'mask' is for, I was kinda hoping it would allow me to colorize only a specific part of a texture but maybe I have the wrong idea altogether?

Hi,

I'm working on a mod, and I need to know which side of a node is clicked.
To put it simply, I put a block (let's call it block_a) on the ground and when I click it with a special tool I want to put a block to the right hand side of block_a (relative to the player's position).
Of course the right hand side is different depending on where the player is standing at the moment of clicking.

Currently I can put my special block_a on the ground and click it with special tool. That is no problem. I can detect the click and put extra blocks in my world. That's no problem either.

But how to determine which block is to the right of the clicked block?

Alternatively is it possible to have a 'front' side to a node? And if that is possible, how to determine the node to the right of the 'front' side?

Any help is greatly appreciated.

mcrefugee, get the player's position, then the node's position, and from there it should be quite easily to calculate.

player:getpos() will give you the player position, and the node position is provided in the rightclicking callback.

Hello all,

Topic: Understanding some bits of tool capabilities?

Reason: I'd just like to understand some parts so I can know what's going on when I make my own tools.

More Info: Let's take the default stone pickaxe.

Code: Select all

minetest.register_tool("default:pick_stone", {
	description = "Stone Pickaxe",
	inventory_image = "default_tool_stonepick.png",
	tool_capabilities = {
		full_punch_interval = 1.3,
		max_drop_level=0,
		groupcaps={
			cracky = {times={[2]=2.0, [3]=1.20}, uses=20, maxlevel=1},
		},
		damage_groups = {fleshy=3},
	},
})

I understand that groupcaps handles what blocks can actually be affected by the tool and how so. I get that uses is tied to the damage inflicted on the tool with use. It's the times and maxlevel part I'm not sure I grasp.

I think the number with fleshy might work similarly?

If someone could help clear up these things, it'd be much appreciated. :)

Topic: How to disable core HUD?
Reason: I'm working on a hud overhaul mod and I'm at that point where I want to disable the core hud elements of the health and breath.
More info: here's a screenshot of the issue I'm having, you can notice it above the hotbar, this issue can be fixed if I edit the game's default core lua files but I want it as a mod so it can be disabled at anytime.

[Napiophelios]

I think this is how Blockman does it with the Hud mod,
he doesnt disable it though:

local function hide_builtin(player)

local function custom_hud(player)

TriBlade9: thank you, I've got it working now.

Know where I can find his mod or his mod's github and thanks! =)

TriBlade9: thank you, I've got it working now.

Glad to hear it! Can't wait to see your mod.

Why can't I loop sound without an object attached to it?

[Kalabasa]

How to get the name of an entity?

Edit:
Answered on IRC:
If object,

Code: Select all

object.get_luaentity().name

If entity

Code: Select all

entity.name

You can loop a sound if you specify an object/player or a position.

Hello again,

While waiting for an answer to my previous question, I came up with another. Haha.

Topic: What is legacy_mineral for?

Reason: To know what it's for. Depending on what it does, maybe I could use it for my custom nodes.

Other Info: In case you don't know what I mean off the top of your head, here it is in the setup for stone.

Code: Select all

minetest.register_node("default:stone", {
	description = "Stone",
	tiles = {"default_stone.png"},
	is_ground_content = true,
	groups = {cracky=3, stone=1},
	drop = 'default:cobble',
	legacy_mineral = true,
	sounds = default.node_sound_stone_defaults(),
})

Thanks for taking the time to read. :)

I have a real dumb question(s) but they have me in confusion.

I am currently making a variant of the simple mobs mod, with all different characters, quite a few of them all with different attributes, rewards, speeds, etc. They use the same api but the code for all the variants are different. The question is: Does having many mods kill frame rate even if using the same model file? In my mind I think it should be okay but in testing they seem to bog down my game, and I don't want that. Is there a different solution to keeping the multiple mobs in world without losing too many FPS other than reducing the draw distance and amount spawned per chunk?

I imagine no, but had to ask anyway.

I think, the most load is created because some resource demanding functions are called too intensive.
For example, if at every server tick every mob call function to find all lua entities around him and checks if this entity is player. Or if at every server tick lua function is called to change every mob position and speed.
When i was tampering "simple mobs" mod for my server, i tried to make such function calls less frequent.

l tried to find "legacy_mineral" (with grep -rl) in other files but it's only in ./games/minimal/mods/default/init.lua and ./games/minetest_game/mods/default/nodes.lua. Maybe it's used for decoration.

Hello Hybrd Dog,

Yes, I couldn't find it anywhere else either. Not a mention in lua_api.txt. I didn't know if it was maybe an outdated property, something like decoration as you said, or what. I don't seem to see it in the other mods I have either, so maybe it's something I can ignore like everyone else seems to be doing. xD That it doesn't do anything special I might want, maybe even just does nothing.

Just can't help but wonder though.

[Kalabasa]

You can loop a sound if you specify an object/player or a position.

What about background music? It's a sound that loop-plays globally and not attached to an object.

Thanks for the great explanation 4aiman! :D
I will toy around with it a bit this weekend. I think I'll first do a simple mob similar to Minecrafts slime thingy.

[BrunoMine]

I know it sounds very simple, but I can not declare variables. Only constants.
example:

Code: Select all

local day = 1;

It does not change value even if I change its value in a function.

Which function do you mean?

Which function do you mean?

Code: Select all

local slot1_image = ""

function brazutec_instalar_em_laptop(texture)

end

		"bgcolor[#080808BB;true]"..
		"image[0,0;15,10;brazutec_desktop.png]"..
		"image[0,0;5,5;"..slot1_imagem.."]",
}

in extra mod

Code: Select all

local new_image = "brazutec_botao_off.png"

minetest.register_on_joinplayer(function(player)
	brazutec_instalar_em_laptop(new_image)
end)
