[good solution for a trigger?]

I tried now:

 

virtual void Collision(Entity* collidedEntity, const Vec3& position, const Vec3& normal, float speed);

static void CollisionHook(Entity* entity0, Entity* entity1, float* position, float* normal, float speed);

 

- in App.h

 

and:

 

void Collision(Entity* collidedEntity, const Vec3& position, const Vec3& normal, float speed){

}
void CollisionHook(Entity* entity0, Entity* entity1, float* position, float* normal, float speed){

System::Print("Entity: " + entity0->GetKeyValue("name") + " collided with: " + entity1->GetKeyValue("name"));

}

 

- in App.cpp

 

The error is:

 

1>App.obj : error LNK2001: Nicht aufgelöstes externes Symbol ""public: virtual void __thiscall App::Collision(class Leadwerks::Entity *,class Leadwerks::Vec3 const &,class Leadwerks::Vec3 const &,float)" (?Collision@App@@UAEXPAVEntity@Leadwerks@@ABVVec3@3@1M@Z)".

 

 

1>App.obj : error LNK2001: Nicht aufgelöstes externes Symbol ""public: static void __cdecl App::CollisionHook(class Leadwerks::Entity *,class Leadwerks::Entity *,float *,float *,float)" (?CollisionHook@App@@SAXPAVEntity@Leadwerks@@0PAM1M@Z)".

 

(it's german hope you can read it. it means 'external unresolved symbol...')

 

i thougt i forgot to link any library but everything is set ok (or is some code wrong?)

if (window->Closed()) return false;

//Press escape to end freelook mode
if (window->KeyHit(Key::Escape))
{

exit(0);

}
.... Everything else has to do with character controllers, movement etc. so it's not really needed

 

App.h:

 

#pragma once
#include "Leadwerks.h"
using namespace Leadwerks;
class App
{
public:
Window* window;
Context* context;
World* world;
Camera* camera;
App();
virtual ~App();
void LoadMapEntity(Entity* e);
virtual bool Start();
virtual bool Loop();
virtual void Collision(Entity* collidedEntity, const Vec3& position, const Vec3& normal, float speed);
static void CollisionHook(Entity* entity0, Entity* entity1, float* position, float* normal, float speed);
};

//Edit:

 

if I add 'App::' in front of both function in App.cpp then i got the error: (translated by google translator:) Access violation when reading at position. I think something with my rguments is wrong but what?

 

:/

Hello,

 

I'm new to Leadwerks and i'm now trying to create triggers with C++

 

I found many examples but either it's for C and in C++ not working or it's old or anything nothing has really worked for me :/

 

So i'm asking is anyone able to give me a good example of a trigger (trigger enter and leave is important) or good ideas?

 

Thanks,

Mex
