From: cloudwalk Date: Tue, 26 May 2020 13:38:28 +0000 (+0000) Subject: Implement clipgroup extension from DarkplacesRM X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=fc4a5f1101c87081f94ad550d6b3fd1beee37b54;p=xonotic%2Fdarkplaces.git Implement clipgroup extension from DarkplacesRM This allows magical things to happen, such as disabling teammate collision in Xonotic. git-svn-id: svn://svn.icculus.org/twilight/trunk/darkplaces@12585 d7cf8633-e32d-0410-b094-e92efae38249 --- diff --git a/cl_collision.c b/cl_collision.c index 56eac018..924d017c 100644 --- a/cl_collision.c +++ b/cl_collision.c @@ -227,6 +227,7 @@ trace_t CL_TracePoint(const vec3_t start, int type, prvm_edict_t *passedict, int // list of entities to test for collisions int numtouchedicts; static prvm_edict_t *touchedicts[MAX_EDICTS]; + int clipgroup; if (hitnetworkentity) *hitnetworkentity = 0; @@ -280,6 +281,8 @@ trace_t CL_TracePoint(const vec3_t start, int type, prvm_edict_t *passedict, int // precalculate passedict's owner edict pointer for comparisons traceowner = passedict ?
