For player:get_look_yaw, it works with my formula. Could it be, that for entities, the yaw has another reference point?
Anyway, could you try flipping x and z (again, sorry).
It seems to be :

Code: Select all

       90
180 ------- 0
       90

When it should be:

Code: Select all

       0
90 ------- 90
      180

My code is correct. But you have to invert the order in vector.subtract. To get the direction from one point to the other, you need to subtract the origin from the target, so vector.subtract(pos2, pos1) should return the right vector. The 90- has to be removed and the formula in yaw2vec reverted to ...

Strange. For me, the code works as expected. It prints "output is empty" until I put something in "in" and triggers allow_take and on_take when I take something. Though I had to add "default" as a dependency, so it doesn't override the inventory formspec. And you are ri...

Can you show me your code?

TeTpaAka

If it is in a node definition, you can use allow_metadata_inventory_put on the input field and use the elements of the inventory to call get_craft_result(). You can put the output in the output slot and then, with allow_inventory_take, you can decrement the input if someone takes the craft result.

You'd replace yaw2vec to a function that also takes the pitch to set the y value: local function yaw2vec(yaw, pitch) pitch = pitch or 0 return { x = math.cos(yaw) * math.cos(pitch), z = math.sin(yaw) * math.cos(pitch), y = math.sin(pitch) } end Edit: Fixed the code. You have to multiply x and z by m...

You need to convert the yaw to a vector and determine the vector between the two positions. If you got that, you need to measure the angle between the two vectors: local function yaw2vec(yaw) return { x = math.cos(yaw), z = math.sin(yaw), y = 0 } end Oh, it was that easy? Thanks! The yaw is the ang...

You probably want a pointer to the environment instead of a hard copy.

Also my compiler complains about the use of c++11. If you want this code to be included to the main codebase, you should avoid c++11.

NewColor.R = (Color1.R * Color2.R)/255
NewColor.G = (Color1.G * Color2.G)/255
NewColor.B = (Color1.B * Color2.B)/255

Further down in the answer.

#00f and #ff0 need to become #0f0 and not #fff

That's the difference between subtractive and additive colour mixing. Try this.

@TeTpaAka: No. Unless I update this mod, of course (sorry for late answer). But I am not sure what exactly you want here. For example: A player gets hit by a spell that makes him blind for 20 seconds. After 5 seconds, he gets hit again, this time with a spell that blinds him for 5 seconds. This spe...

Take a look at api.lua.

Code: Select all

areas:getAreasAtPos(pos)

or

Code: Select all

areas:getNodeOwners(pos)

seem to be what you want.

There's one case where I don't like the warning. Sometimes when creating a namespace you don't want to depend on the order of execution. So you might write this in two or more different places: namespace = namespace or {}; namespace.var = ...; function namespace.func() ... end; I'd be nice to diffe...

I have a tool that places a node, a marker and an arrow, however I want the arrow to point in the direction that the user is pointing when they use the tool. I have the node set so if you place it directly all works as it should, but when using it as a tool it doesn't. Is this possible, am I just m...

Thanks to a recent minetest pull from TeTpeAka the next major problem in fractured has been solved! You will need the newest version of minetest for this to work. But wildweapons now uses register_on_punchplayer and it makes the whole process of controlling where players can damage each other trivi...

Hier habe ich eine kleine Beispielmod geschrieben:

Damit es funktioniert musst du nur in den oberen Zeilen die obere und die untere Ecke der Spawnregion angeben. (Drücke F5 ingame damit du die Koordinaten erfährst).

It could be a little problematic that there are multiple different backends. There are, at least: simple mobs by Pilzadam (+some forks that don't change the api much) mobs redo by TenPlus1 creatures by BlockMen creatures by MirceaKitsune ... (probably some more) The difficulty isn't the amount of ba...

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_game/blob/master/mods/screwdriver/ini...

Hallo gravelman,

Das ist im Moment noch nicht möglich. Siehe hier.
Aber sobald dieser pull request ins Spiel kommt, ist es möglich, pvp partiell auszuschalten. (Ich bin zuversichtlich, dass er es schafft.)

TeTpaAka

Would this help?
This is, I think, exactly what you described.

TeTpaAka

I have a question. I'm rather new to computer skills when it comes to coding and all that and only just figured out where to put mods and maps. If you could explain how to use API, that would be great. Thank you! First, you register a quest on load time of the mod, like you would do with a node/ite...
