From d499ec483837fa7210176ef39beba2d5a3a5a61d Mon Sep 17 00:00:00 2001 From: Auke Kok Date: Fri, 27 May 2016 21:08:23 -0700 Subject: Particles: Add option to remove particles on collision Adds the particle option `collision_removal = bool` Some particles are hard to use right now since they either go through solid blocks (without collision detection), and with collision detection enabled they (e.g. raindrops) would just stop dead on the floor and sit there until they expire, or worse, scrape along a wall or ceiling. We can solve the problem by adding a boolean flag that tells the particle to be removed if it ever collides with something. This will make it easier to add rain that doesn't fall through your roof or stick on the top of it. Or clouds and smoke that don't go through trees. Particles that collide with this flag are marked expired unconditionally, causing them to be treated like normal expired particles and cleaned up normally. Documentation is adjusted accordingly. An added bonus of this patch is that particles can potentially collide many times with nodes, and this reduces the amount of collisions to 1 (max), which may end up reducing particle load on the client. --- src/client.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'src/client.h') diff --git a/src/client.h b/src/client.h index cdadb9d3e..a7eb22ad9 100644 --- a/src/client.h +++ b/src/client.h @@ -182,6 +182,7 @@ struct ClientEvent f32 expirationtime; f32 size; bool collisiondetection; + bool collision_removal; bool vertical; std::string *texture; } spawn_particle; @@ -199,6 +200,7 @@ struct ClientEvent f32 minsize; f32 maxsize; bool collisiondetection; + bool collision_removal; bool vertical; std::string *texture; u32 id; -- cgit v1.2.3
