From e1ff5b13619666e5b987ecf4faaf294400ffd979 Mon Sep 17 00:00:00 2001 From: Jeija Date: Wed, 23 Jan 2013 18:32:02 +0100 Subject: [PATCH] Allow spawning particles from the server, from lua Spawn single particles or make use of ParticleSpawner for many randomly spawned particles. Accessible in Lua using minetest.spawn_particle and minetest.add_particlespawner. Increase Protocol Version to 17.
