[Mod] Limit chat by distance [0.1.2] [shout]

[srifqi]

Hi!
This mod limit your message by distance so that your message only sent to player within distance boundary.

Features:

• Limit who can hear your message by distance given in shout.DISTANCE parameter
• A chat command /sh to broadcast your message (pay 1 stick by default, can be changed in shout.PAYMENT parameter)

See README

it might be better to do:

Code: Select all

math.sqrt(x * x + y * y + z * z)

https://github.com/srifqi/shout/blob/ma ... it.lua#L20

It's less square rooting (but maybe less readable, Idk) probably not worth optimising :P

chatplus can already do this, but it comes with the bloat of ignoring and inboxes, so it's good to have a standalone version (as in, doesn't provide anything else other than distance limiting). /sh having a cost, a stick, is quite interesting as a game play mechanic.

sticks are kinda a little, say cheap, maybe something cheap but not almost unlimited brodcasts kinda cheap

I was just copying from Minetest built-in lua. Never thought about this optimization, I already know that formula, just forgot when writing the code. :P

Never heard about your mod, sorry. :D

Maybe, I should add parameter for this, so that you can easily change what we should pay.

Also, should I add a configuration per world?

UPDATE 0.1.1! (Payment Update)
Changes:

• Add parameter to change payment
• A little performance update by rubenwardy (see: viewtopic.php?p=181468#p181468)

Even better is to compare squares of distances and not need square roots at all. :-P

Ah, Phytagoras Theorem!

Code: Select all

c * c = a * a + b * b

How can I forget that? Thanks prestidigitator. Will be avaiable in next update.

Minetest have built-in helper: vector.distance(senderpos, recieverpos)

Good idea for taking payment for shouting, i must add it to my chat mod too!

Do you mean this?

Code: Select all

function vector.distance(a, b)
	local x = a.x - b.x
	local y = a.y - b.y
	local z = a.z - b.z
	return math.hypot(x, math.hypot(y, z))
end

You know? We (me, rubenwardy, and prestidigitator) are doing optimisation. So, rather than do math.hypot several times, we compare the distance "squared". So, we save a little bit time.

Yay!

UPDATE 0.1.2! (Performance Update)
Change:

• Use Phytagoras Theorem c^2 = a^2 + b^2
