From ccc694bbcd3f159d3b098fb2cface3ebc1ce4c17 Mon Sep 17 00:00:00 2001 From: MajorCooke Date: Thu, 7 Jan 2016 17:09:02 -0600 Subject: [PATCH 1/5] - Added the following flags, all affixed with CPXF_: - NODISTANCE: Disables distance checking. - CHECKSIGHT: The qualifying actor must be in sight in order to count. - SET: Gets the first qualifying actor and sets the calling actor's specified pointer to it. - SETONPTR: If the function is being aimed at another actor other than the caller, sets that actor's pointers instead. Requires a SET* flag to work. - FARTHEST: The actor farthest from the checking actor is set as the pointer. Requires a SET* flag to work. - CLOSEST: The closest qualifying actor is set as the pointer. Requires a SET* flag to work. --- src/thingdef/thingdef_codeptr.cpp | 83 ++++++++++++++++++++++++++---- wadsrc/static/actors/constants.txt | 8 +++ 2 files changed, 82 insertions(+), 9 deletions(-) diff --git a/src/thingdef/thingdef_codeptr.cpp b/src/thingdef/thingdef_codeptr.cpp index 89299e0fad..5dac7adbef 100644 --- a/src/thingdef/thingdef_codeptr.cpp +++ b/src/thingdef/thingdef_codeptr.cpp @@ -5908,6 +5908,14 @@ enum CPXFflags CPXF_COUNTDEAD = 1 << 3, CPXF_DEADONLY = 1 << 4, CPXF_EXACT = 1 << 5, + CPXF_SETTARGET = 1 << 6, + CPXF_SETMASTER = 1 << 7, + CPXF_SETTRACER = 1 << 8, + CPXF_FARTHEST = 1 << 9, + CPXF_CLOSEST = 1 << 10, + CPXF_SETONPTR = 1 << 11, + CPXF_NODISTANCE = 1 << 12, + CPXF_CHECKSIGHT = 1 << 13, }; DEFINE_ACTION_FUNCTION_PARAMS(AActor, A_CheckProximity) { @@ -5920,17 +5928,28 @@ DEFINE_ACTION_FUNCTION_PARAMS(AActor, A_CheckProximity) ACTION_PARAM_INT(ptr, 5); ACTION_SET_RESULT(false); //No inventory chain results please. + + if (!jump) + { + if (!(flags & (CPXF_SETTARGET | CPXF_SETMASTER | CPXF_SETTRACER))) + return; + } AActor *ref = COPY_AAPTR(self, ptr); //We need these to check out. - if (!ref || !jump || !classname || distance <= 0) + if (!ref || !classname || ((distance <= 0) && !(flags & CPXF_NODISTANCE))) return; int counter = 0; bool result = false; + const double distsquared = (double)distance * (double)distance; + double closer, farther = 0, current = closer = distsquared; + const bool ptrWillChange = !!(flags & (CPXF_SETTARGET | CPXF_SETMASTER | CPXF_SETTRACER)); + const bool ptrDistPref = !!(flags & (CPXF_CLOSEST | CPXF_FARTHEST)); + TThinkerIterator it; - AActor * mo; + AActor *mo, *dist = NULL; //[MC] Process of elimination, I think, will get through this as quickly and //efficiently as possible. @@ -5949,12 +5968,37 @@ DEFINE_ACTION_FUNCTION_PARAMS(AActor, A_CheckProximity) else if (classname != mo->GetClass()) continue; - //Make sure it's in range and respect the desire for Z or not. - if (P_AproxDistance(ref->x - mo->x, ref->y - mo->y) < distance && - ((flags & CPXF_NOZ) || - ((ref->z > mo->z && ref->z - (mo->z + mo->height) < distance) || - (ref->z <= mo->z && mo->z - (ref->z + ref->height) < distance)))) + //[MC]Make sure it's in range and respect the desire for Z or not.
