Irrlicht Engine

Well, that depends. You need to compute distance of two spheres (center to center) than compare that to sum of their radiuses when you compute sphere collision. Distance is computed using square root which is quit expensive: dis = sqrt(X*X + Y*Y + Z*Z) You can compare squared distance to sum of squa...

My be code I posted here can help you somehow:

Are you sure it is not GIMBAL LOCK?

Some good running circle / walking circle animations plus some others:

Can be downloaded in low res but still usable for reference when animating.

If you plan to do some serious collision on large scale than you should made your own collision manager. There are many things you can do to optimize collision detection and response and it largely depend on character of your project. few things as an example: First thing is of course to prevent col...

shouldn't I be using getIntersectionWithLine? Depends. If you want your line to intersect only with objects visible by camera, use getIntersectionWithLimitedLine. Otherwise use getIntersectionWithLine. However you may pick objects/planes which are actually above your camera (I was not testing that ...

I see. But why second function definition works. "it" is also ConstIterator: const wchar_t* MGUIListBox::getSelectedItemText() const { core::list<ListItem>::ConstIterator it = Selected; return (*it).Text; } And what would be correct way of getting text out of list item? Should I declare fu...

Well I was not verifying it in any way but getIntersectionWithLimitedLine tests intersection of plane with line between its start and end point so name is correct. It is limited line. In math line is not limited, it is defined by one point and vector and is infinite. You can also have half line for ...

It's set in onEvent() by user input ...I did stripe that class down to bare minimum. And that function actually looks like this (to return 0 if item was not selected): const wchar_t* MGUIListBox::getSelectedItemText() const { if(Selected == core::list<ListItem>::ConstIterator() ) return 0; return (*...

Ok. Now that should have been written at the beginning of this post. Here is simple example which place sphere on "ground plane" at mouse coordinates. Just click with mouse somewhere on the screen: #include <irrlicht.h> using namespace irr; class MEventReceiver : public IEventReceiver { pu...

Well say I have class like this: class MGUIListBox { struct ListItem { const wchar_t *Text; }; core::list<ListItem>::ConstIterator Selected; core::list<ListItem> List; public: virtual const wchar_t* getSelectedItemText() const; }; Now if function definition looks like this compiler throws error: pas...

Hmm, that code is bit confusing. By setting camera far plane to targetZ you use that Z coordinate in local space of camera. You wrote you want to set it in global space instead, right? Can you may be describe in some detail what you want to achieve in general? Are you trying to find point on terrain...

Ok, just give me some time. I will look at the files (those are few years old projects of mine) and send you best I can find. May be I will be able to sent you even boned ones. Also let me know, what file format will suit you best. I can convert them in to most of the common formats: .x .obj .ms3d o...

Well, only way apart of either declaring something global or passing it as function argument is to use some kind of class which would hold all the declarations, including function. Can be some kind of "gamemanager".
