Cannot compile the RTS Camera example in the wiki

[fukuda]

hi, I'm trying to include the wiki's RTS Camera into my project, to test it and expand its features.

But... The compiler fails with the SViewFrustrum object:

Code: Select all

1st, it says that 'SViewFrustrum' has no type (when its the type of the function getViewFrustrum)

2nd, at 'scene::SViewFrustrum View;' it says thet SViewFrustrum is not a valid type.

[monkeycracks]

It is now SViewFrustum

[fukuda]

Oh thanks, yes I was a bit dumb, well, now it only says that 'virtual const SViewFrustum* getViewFrustum()' (the engine one) is abstract and I cannot allocate a camera because of that.

[monkeycracks]

Make sure that your class has that function somewhere.

Also, make sure you do this somewhere

Code: Select all

const SViewFrustum* RTSCamera::getViewFrustum()
{
  return View;
} 

Well, I think that's correct anyways, it's been a while since I fooled with it.

[fukuda]

Nah, it didn't worked

it gives me the same error

Code: Select all

const SViewFrustum* RTSCamera::getViewFrustum()
{
   return ViewArea;
}

it's ViewArea, btw

[monkeycracks]

Not sure I can help much more then, heh. Sorry.

I guess the const should be AFTER the parameters, for the whole method being const.
