From a28a80e45ffe9f576b3e0d641039603393278025 Mon Sep 17 00:00:00 2001 From: Steve Dudenhoeffer Date: Tue, 24 Jul 2007 06:05:43 +0000 Subject: [PATCH] Few additions to fakemeta: Implemented amb632 - lookup_sequence, also added set_controller (since it dealt with models). Implemented set_pev_string, for setting with an already allocated string handle. Also added pev_serial, to get the entity serial number. --- dlls/fakemeta/misc.cpp | 148 +++++++++++++++++++++++++++++++++++ dlls/fakemeta/pev.cpp | 49 ++++++++++++ plugins/include/fakemeta.inc | 91 ++++++++++++++++++--- 3 files changed, 277 insertions(+), 11 deletions(-) diff --git a/dlls/fakemeta/misc.cpp b/dlls/fakemeta/misc.cpp index 6273322c..1bae3c71 100644 --- a/dlls/fakemeta/misc.cpp +++ b/dlls/fakemeta/misc.cpp @@ -1,4 +1,5 @@ #include "fakemeta_amxx.h" +#include // HLSDK, for the animation natives static cell AMX_NATIVE_CALL copy_infokey_buffer(AMX *amx, cell *params) { @@ -7,7 +8,154 @@ static cell AMX_NATIVE_CALL copy_infokey_buffer(AMX *amx, cell *params) return MF_SetAmxString(amx, params[2], infobuffer, params[3]); } +int UTIL_stricmp(const char *s1, const char *s2) +{ + unsigned char c1, c2; + + for (;;) { + c1 = *s1++; + c2 = *s2++; + + if (!c1 || !c2) + break; + + if (c1 == c2) + continue; + + if ((c1 = tolower(c1)) != (c2 = tolower(c2))) + break; + } + return (int)c1 - (int)c2; +} + +// lookup_sequence(entid, "sequence name", &Float:framerate = 0.0, &bool:loops = false, &Float:groundspeed = 0.0); +static cell AMX_NATIVE_CALL lookup_sequence(AMX* amx, cell* params) +{ + int index = params[1]; + + CHECK_ENTITY(index); + + edict_t* ent = INDEXENT(index); + + studiohdr_t* pstudiohdr = static_cast(GET_MODEL_PTR(ent)); + + if (pstudiohdr == NULL) + { + MF_LogError(amx, AMX_ERR_NATIVE, "Could not retrieve the model pointer from the entity provided."); + return 0; + } + + mstudioseqdesc_t* pseqdesc; + + pseqdesc = reinterpret_cast( + reinterpret_cast(pstudiohdr) + pstudiohdr->seqindex); + + char* label = MF_GetAmxString(amx, params[2], 0, NULL); + + for (int i = 0; i < pstudiohdr->numseq; i++) + { + if (UTIL_stricmp( pseqdesc[i].label, label ) == 0) + { + REAL* FrameRate = reinterpret_cast(MF_GetAmxAddr(amx, params[3])); + cell* Loops = MF_GetAmxAddr(amx, params[4]); + REAL* GroundSpeed = reinterpret_cast(MF_GetAmxAddr(amx, params[5])); + + // Taken from HLSDK: animation & animating.cpp + pseqdesc = &pseqdesc[i]; + *FrameRate = 256 * pseqdesc->fps / (pseqdesc->numframes - 1); + + *GroundSpeed = sqrt( pseqdesc->linearmovement[0]*pseqdesc->linearmovement[0]+ pseqdesc->linearmovement[1]*pseqdesc->linearmovement[1]+ pseqdesc->linearmovement[2]*pseqdesc->linearmovement[2] ); + *GroundSpeed = *GroundSpeed * pseqdesc->fps / (pseqdesc->numframes - 1); + + *Loops = pseqdesc->flags & STUDIO_LOOPING; + return i; + } + } + + return -1; + +}; +// Float:set_controller(entid, controllerid, Float:value); +static cell AMX_NATIVE_CALL set_controller(AMX* amx, cell* params) +{ +// From animation.cpp from the HLSDK +// SetController( void *pmodel, entvars_t *pev, int iController, float flValue ) + int entindex = params[1]; + CHECK_ENTITY(entindex); + edict_t* entity = INDEXENT(entindex); + + int iController = params[2]; + + if (iController < 0 || iController > 3) + { + MF_LogError(amx, AMX_ERR_NATIVE, "Invalid controller id passed.
