From 7f1bb7af92841ca3d12ce3dc69238995b8bd0b42 Mon Sep 17 00:00:00 2001 From: cora Date: Sat, 25 Sep 2021 02:06:39 +0200 Subject: [PATCH] replace nether dust particles with p. spawners mcl2 uses add_particle for nether dust resulting in a 10-fold increase in network traffic when in the nether. Nether dust is not configurable making it impossible to turn this off for server admins. this commit replaces the add_particle method with particle spawners --- mods/ENVIRONMENT/mcl_weather/nether_dust.lua | 86 +++++++++++++------- 1 file changed, 58 insertions(+), 28 deletions(-) diff --git a/mods/ENVIRONMENT/mcl_weather/nether_dust.lua b/mods/ENVIRONMENT/mcl_weather/nether_dust.lua index d328dae21..4ab9e4081 100644 --- a/mods/ENVIRONMENT/mcl_weather/nether_dust.lua +++ b/mods/ENVIRONMENT/mcl_weather/nether_dust.lua @@ -1,36 +1,66 @@ mcl_weather.nether_dust = {} -mcl_weather.nether_dust.particles_count = 99 +mcl_weather.nether_dust.particlespawners = {} --- calculates coordinates and draw particles for Nether dust -function mcl_weather.nether_dust.add_dust_particles(player) - for i=mcl_weather.nether_dust.particles_count, 1,-1 do - local rpx, rpy, rpz = mcl_weather.get_random_pos_by_player_look_dir(player) - minetest.add_particle({ - pos = {x = rpx, y = rpy - math.random(6, 18), z = rpz}, - velocity = {x = math.random(-30,30)*0.01, y = math.random(-15,15)*0.01, z = math.random(-30,30)*0.01}, - acceleration = {x = math.random(-50,50)*0.02, y = math.random(-20,20)*0.02, z = math.random(-50,50)*0.02}, - expirationtime = 3, - size = math.random(6,20)*0.01, - collisiondetection = false, - object_collision = false, - vertical = false, - glow = math.random(0,minetest.LIGHT_MAX), - texture = "mcl_particles_nether_dust"..tostring(i%3+1)..".png", - playername = player:get_player_name() - }) +local psdef= { + amount = 150, + time = 0, + minpos = vector.new(-15,-15,-15), + maxpos =vector.new(15,15,15), + minvel = vector.new(-0.3,-0.15,-1), + maxvel = vector.new(0.3,0.15,0.3), + minacc = vector.new(-1,-0.4,-1), + maxacc = vector.new(1,0.4,1), + minexptime = 1, + maxexptime = 10, + minsize = 0.2, + maxsize = 0.7, + collisiondetection = false, + collision_removal = false, + object_collision = false, + vertical = false +} + +local function check_player(player) + local name=player:get_player_name() + if mcl_worlds.has_dust(player:get_pos()) and not mcl_weather.nether_dust.particlespawners[name] then + return true + end +end + +mcl_weather.nether_dust.add_particlespawners = function(player) + local name=player:get_player_name(name) + mcl_weather.nether_dust.particlespawners[name]={} + psdef.playername = name + psdef.attached = player + psdef.glow = math.random(0,minetest.LIGHT_MAX) + for i=1,3 do + psdef.texture="mcl_particles_nether_dust"..i..".png" + mcl_weather.nether_dust.particlespawners[name][i]=minetest.add_particlespawner(psdef) end end -local timer = 0 -minetest.register_globalstep(function(dtime) - timer = timer + dtime - if timer < 0.7 then return end - timer = 0 - - for _, player in pairs(minetest.get_connected_players()) do - if not mcl_worlds.has_dust(player:get_pos()) then - return false +mcl_weather.nether_dust.delete_particlespawners = function(player) + local name=player:get_player_name(name) + if mcl_weather.nether_dust.particlespawners[name] then + for i=1,3 do + minetest.delete_particlespawner(mcl_weather.nether_dust.particlespawners[name][i]) end - mcl_weather.nether_dust.add_dust_particles(player) + mcl_weather.nether_dust.particlespawners[name]=nil + end +end + +mcl_worlds.register_on_dimension_change(function(player, dimension) + if check_player(player) then + return mcl_weather.nether_dust.add_particlespawners(player) + end + mcl_weather.nether_dust.delete_particlespawners(player) +end) + +minetest.register_on_joinplayer(function(player) + if check_player(player) then + mcl_weather.nether_dust.add_particlespawners(player) end end) +minetest.register_on_leaveplayer(function(player) + mcl_weather.nether_dust.delete_particlespawners(player) +end)
