Returns true if they both resolve to the same value. Null values can be explicitly tested using IsPointerEqual(AAPTR_NULL, ...) ACS: IsPointerEqual(int aaptr1, int aaptr2, int tid1 = 0, int tid2 = 0) This function lets you compare pointers from other actors than the activator, using tids. Tid1 determines the actor used to resolve aaptr1, Tid2 does the same for aaptr2. If tid1 and tid2 are equal, the same actor will be used for resolving both pointers (that could always happen randomly; this way you know it will happen). --- src/namedef.h | 1 + src/p_acs.cpp | 17 +++++++++++++++ src/thingdef/thingdef_function.cpp | 35 +++++++++++++++++++++++++++++- 3 files changed, 52 insertions(+), 1 deletion(-) diff --git a/src/namedef.h b/src/namedef.h index 1e7fbd0d3..5c65ab655 100644 --- a/src/namedef.h +++ b/src/namedef.h @@ -299,6 +299,7 @@ xx(ACS_NamedExecuteWithResult) xx(CallACS) xx(Sqrt) xx(CheckClass) +xx(IsPointerEqual) // Various actor names which are used internally xx(MapSpot) diff --git a/src/p_acs.cpp b/src/p_acs.cpp index 983728c8d..9fa5079ff 100644 --- a/src/p_acs.cpp +++ b/src/p_acs.cpp @@ -4373,6 +4373,7 @@ enum EACSFunctions ACSF_GetArmorInfo, ACSF_DropInventory, ACSF_PickActor, + ACSF_IsPointerEqual, /* Zandronum's - these must be skipped when we reach 99! -100:ResetMap(0), @@ -5630,6 +5631,22 @@ doplaysound: if (funcIndex == ACSF_PlayActorSound) } break; + case ACSF_IsPointerEqual: + { + int tid1 = 0, tid2 = 0; + switch (argCount) + { + case 4: tid2 = args[3]; + case 3: tid1 = args[2]; + } + + actor = SingleActorFromTID(tid1, activator); + AActor * actor2 = tid2 == tid1 ? actor : SingleActorFromTID(tid2, activator); + + return COPY_AAPTR(actor, args[0]) == COPY_AAPTR(actor2, args[1]); + } + break; + default: break; } diff --git a/src/thingdef/thingdef_function.cpp b/src/thingdef/thingdef_function.cpp index 9bf80dcaa..fcc936017 100644 --- a/src/thingdef/thingdef_function.cpp +++ b/src/thingdef/thingdef_function.cpp @@ -260,4 +260,37 @@ class FxGlobalFunctionCall_CheckClass : public FxGlobalFunctionCall } }; -GLOBALFUNCTION_ADDER(CheckClass); \ No newline at end of file +GLOBALFUNCTION_ADDER(CheckClass); + +//========================================================================== +// +// Function: ispointerequal +// +//========================================================================== + +class FxGlobalFunctionCall_IsPointerEqual : public FxGlobalFunctionCall +{ + public: + GLOBALFUNCTION_DEFINE(IsPointerEqual); + + FxExpression *Resolve(FCompileContext& ctx) + { + CHECKRESOLVED(); + + if (!ResolveArgs(ctx, 2, 2, true)) + return NULL; + + ValueType = VAL_Int; + return this; + } + + ExpVal EvalExpression(AActor *self) + { + ExpVal ret; + ret.Type = VAL_Int; + ret.Int = COPY_AAPTR(self, (*ArgList)[0]->EvalExpression(self).GetInt()) == COPY_AAPTR(self, (*ArgList)[1]->EvalExpression(self).GetInt()); + return ret; + } +}; + +GLOBALFUNCTION_ADDER(IsPointerEqual); \ No newline at end of file From c4f0f95ec8bc0320f0d50be2b55bdc55bc016843 Mon Sep 17 00:00:00 2001 From: fdari Date: Sun, 28 Sep 2014 15:06:52 +0200 Subject: [PATCH 3/4] Get linetarget (aim target) from any actor (not just player): AAPTR_LINETARGET --- src/actorptrselect.cpp | 7 +++++++ src/actorptrselect.h | 3 ++- wadsrc/static/actors/constants.txt | 31 +++++++++++++++--------------- 3 files changed, 25 insertions(+), 16 deletions(-) diff --git a/src/actorptrselect.cpp b/src/actorptrselect.cpp index f1f50eeb5..774067550 100644 --- a/src/actorptrselect.cpp +++ b/src/actorptrselect.cpp @@ -56,6 +56,13 @@ AActor *COPY_AAPTR(AActor *origin, int selector) case AAPTR_TRACER: return origin->tracer; case AAPTR_FRIENDPLAYER: return origin->FriendPlayer ?
