My program keeps crashing once I try to make my custom class use some of its own functions
My custom class looks like this:
Entity.h
#ifndef _ENTITIES
#define _ENTITIES
#include "actual.h"
#include "Manager.h"
struct Position
{
float x, y, z;
};
class Entity
{
public:
Entity();
~Entity();
bool Init(Actual*, int);
Actual* GetActual();
Position* GetPosition();
void SetPosition(float, float, float);
void SetPosition(Position*);
bool IsSpawned();
bool Render(Manager*);
bool Spawn(Position*);
int GetID();
private:
bool spawned;
Actual* actual;
Position* position;
int entityID;
};
#endif
Entity.cpp
#include "stdafx.h"
#include "Entity.h"
#include <string>
#include "Debug.h"
Entity::Entity()
{
spawned = false;
}
Entity::~Entity()
{
}
bool Entity::Init(Actual* base, int id)
{
if (base->IsLoaded() == false)
{
return false;
}
std::string::size_type sz;
entityID = id;
actual = base;
return true;
}
Position* Entity::GetPosition()
{
return position;
}
void Entity::SetPosition(float x, float y, float z)
{
Position* _P = new Position;
_P->x = x;
_P->y = y;
_P->z = z;
position = _P;
}
void Entity::SetPosition(Position* newPos)
{
position = newPos;
}
bool Entity::IsSpawned()
{
return spawned;
}
bool Entity::Spawn(Position* SpawnPos)
{
pos = SpawnPos;
spawned = true;
return true;
}
int Entity::GetID() // this is the unique id that the entity gets
{
return entityID;
}
// render the entity (only if spawned)
bool Entity::Render(OtherManager* rm)
{
// this is where the crash happens
if (IsSpawned() == true)
{
if (actual->HasEntryValue("EntityModel") == false)
return false;
model* m;
rm->GetResource((char*)actual->GetEntryValue("EntityModel", 0).c_str(), m);
// render code
return true;
}
return false;
}
the Manager.h
#ifndef _MANAGER_
#define _MANAGER_
#include "Actual.h"
#include "Entity.h"
#include "OtherManager.h"
#include <Windows.h>
const int MAX_ENTITIES = 2024;
class Manager
{
public:
Manager();
~Manager();
bool AddComponent(Actual*, DifVector); // returns Entity
bool Render(OtherManager*);
private:
Entity* Entities[MAX_ENTITIES];
int entity_count;
int nextEID;
};
#endif
the Manager.cpp
#include "stdafx.h"
#include "Manager.h"
#include "Debug.h"
Manager::Manager()
{
entity_count = -1;
nextEID = 0;
}
Manager::~Manager()
{
}
bool Manager::AddComponent(Actual* base, DifVector spawnpos)
{
bool result;
entity_count = nextEID;
Entities[entity_count] = new Entity();
result = Entities[entity_count]->Init(base, entity_count);
if (!result)
{
return false;
}
Position* tempPOS = new Position;
tempPOS->x = spawnpos.x;
tempPOS->y = spawnpos.y;
tempPOS->z = spawnpos.z;
result = Entities[entity_count]->Spawn(tempPOS);
if (!result)
{
return false;
}
nextEID = nextEID + 1;
return true;
}
bool Manager::Render(OtherManager* rm)
{
if (entity_count = 0)
Entities[0]->Render(rm);
for (int i=0; i=nextEID; i++)
{
Entities[i]->Render(rm);
}
return true;
}
I have modified the code a bit to not shown all the stuff I dont think has anything to do with the problem.
The way I use the code is:
DifVector spawnposition = SelectionPositionSpawnFromCamera(MainCam);
_Manager->AddComponent(ToSpawn, spawnposition); // ToSpawn is an 'Actual' class that has been preset same goes for the spawnposition
// render function
_Manager->Render(rm_WB);
