Copyback Vector
Hello. I am trying to call a function that, after executing get a position in a variable:
PHP Code:
cell_t L4D2_GetRandomSpawnPosition(IPluginContext *pContext, const cell_t *params)
{
if (g_pZombieManager == NULL)
{
return pContext->ThrowNativeError("ZombieManager unsupported or not available; file a bug report");
}
static ICallWrapper *pWrapper = NULL;
if (!pWrapper)
{
REGISTER_NATIVE_ADDR("GetRandomSpawnPosition",
PassInfo pass[4]; \
pass[0].flags = PASSFLAG_BYVAL; \
pass[0].size = sizeof(ZombieClassType); \
pass[0].type = PassType_Basic; \
pass[1].flags = PASSFLAG_BYVAL; \
pass[1].size = sizeof(int); \
pass[1].type = PassType_Basic; \
pass[2].flags = PASSFLAG_BYVAL; \
pass[2].size = sizeof(CBaseEntity *); \
pass[2].type = PassType_Basic; \
pass[3].flags = PASSFLAG_BYVAL; \
pass[3].size = sizeof(Vector*); \
pass[3].type = PassType_Basic; \
pWrapper = g_pBinTools->CreateCall(addr, CallConv_ThisCall, NULL, pass, 4));
}
int client = params[3];
CBaseEntity * pClient = NULL;
if (client != -1)
{
pClient = UTIL_GetCBaseEntity(client, true);
if(pClient == NULL)
{
return pContext->ThrowNativeError("Invalid client entity");
}
}
Vector vector;
vector[0] = sp_ctof(0.0);
vector[1] = sp_ctof(0.0);
vector[2] = sp_ctof(0.0);
unsigned char vstk[ sizeof(void*) + sizeof(ZombieClassType) + sizeof(int) + sizeof(CBaseEntity *) + sizeof(Vector*) ];
unsigned char *vptr = vstk;
*(void **)vptr = g_pZombieManager;
vptr += sizeof(void *);
*(cell_t*)vptr = params[1];
vptr += sizeof(ZombieClassType);
*(int *)vptr = params[2];
vptr += sizeof(int *);
*(CBaseEntity **)vptr = pClient;
vptr += sizeof(CBaseEntity *);
*(Vector**)vptr = &vector;
pWrapper->Execute(vstk, NULL);
const void *buffer = (const unsigned char *)vstk + pWrapper->GetParamInfo(3)->offset;
Vector *v = NULL;
v = *(Vector**)buffer;
cell_t* addr;
pContext->LocalToPhysAddr(params[4], &addr);
addr[0]=sp_ftoc(v->x);
addr[1]=sp_ftoc(v->y);
addr[2]=sp_ftoc(v->z);
return 0;
}
It works in linux, but in windows I get a server crash on pWrapper->Execute(vstk, NULL);... How can I assign a different solution so that after the call, the function returns an updated variable (like for example VENCODE_FLAG_COPYBACK in sdktools)? |
