Irrlicht Engine

Hi,

I've downloaded the serializable Bullet animator.
When I tried compiling it (with MSVC++ 2008), I get these errors:

c:\documents and settings\******\mijn documenten\visual studio 2008\projects\game\game\gminigolfapp.cpp(84) : error C2259: 'CWorldEditorGUI' : cannot instantiate abstract class

Can someone help?

Well I will take a guess as to why this doesn't work:

'bool irr::IEventReceiver::OnEvent(const irr::SEvent &)' : is abstract

I am guessing that there is a:

Code: Select all

virtual bool OnEvent(irr::SEvent event)

instead of

Code: Select all

virtual bool OnEvent(const irr::SEvent& event)

I get the same error if i change it to:

Code: Select all

bool CWorldEditorGUI::OnEvent(const SEvent& event)

Well, that solved one of the problems, but there remain several others. You have to adjust your app to the latest API, otherwise some pure virtual methods will exist. Check for const qualifiers and s32/u32 differences.

@hybrid: Actually, none of the problems is solved yet.

'irr::scene::CBulletAnimatorManager' : cannot instantiate abstract class
due to following members:
'irr::u32 irr::scene::ISceneNodeAnimatorFactory::getCreatableSceneNodeAnimatorTypeCount(void) const' : is abstract

This is telling you that your CBulletAnimatorManager implementation does not have a method that exactly matches:

Code: Select all

u32 getCreatableSceneNodeAnimatorTypeCount(void) const

So do you have an exact implementation of this method? Does it return a u32 rather than an i32? Is it a const method?
