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/rocket.c | 1 + 1 file changed, 1 insertion(+) (limited to 'src/modules/sparkler/rocket.c') diff --git a/src/modules/sparkler/rocket.c b/src/modules/sparkler/rocket.c index ae628d3..b56c324 100644 --- a/src/modules/sparkler/rocket.c +++ b/src/modules/sparkler/rocket.c @@ -48,6 +48,7 @@ static int rocket_init(particles_t *particles, particle_t *p) ctxt->last_velocity = p->props->velocity; p->props->drag = 0.4; p->props->mass = 0.8; + p->props->virtual = 0; return 1; } -- cgit v1.2.3
