From 9f499b0590b1a7d56c36ec5d093e82795c3aba19 Mon Sep 17 00:00:00 2001 From: Vito Caputo Date: Wed, 26 Apr 2017 16:02:30 -0700 Subject: sparkler: add virtual flag to particle_props_t The burst particle abused a zero mass to circumvent the effects of aging. Instead use an explicit virtual flag to suppress aging, change busrt_cb to ignore all virtual particles instead of only its center. Previously burst_cb would thrust other bursts like any other particle, and this was incorrect. Now burst centers are always stationary, even when they overlap other bursts. --- src/modules/sparkler/particle.h | 1 + 1 file changed, 1 insertion(+) (limited to 'src/modules/sparkler/particle.h') diff --git a/src/modules/sparkler/particle.h b/src/modules/sparkler/particle.h index 95c117e..c63024d 100644 --- a/src/modules/sparkler/particle.h +++ b/src/modules/sparkler/particle.h @@ -12,6 +12,7 @@ typedef struct particle_props_t { float mass; /* mass of particle */ float drag; /* drag of particle */ int of_use:1; /* are these properties of use/meaningful? */ + int virtual:1; /* is this a virtual particle?
