Irrlicht Engine

I cam across some irrlicht code belonging to the older versions in the ODE & irrlicht tutorial.

In the methods which converts quaternions to euler and vice versa, there were core::GRAD_PI and core::GRAD_PI2.

I am currently using version 1.7.1 and there isn't any constant which matches the 2 above ...

I am currently using a quake 3 map as my irrlicht scene (the same quake 3 map used in the quake3 map and collision irrlicht tutorials). I also added some bill board scene nodes to represent navigation path nodes.

A strange thing happens such that even if the camera is right in front of a wall or ...

I am trying to display and use the text which is input into an EditBox. The text has to be converted from a wchar_t* to a char* in order to be used.

What I did is this:

const wchar_t* startIndex = editBox1->getText();

char* start = new char[wcslen(startIndex) + 1];
cout<<wcslen(startIndex)<<endl ...

I added an irrlicht IGUIEditBox via the IGUIEnvironment pointer using the addEditBox method.

The addEditBox method returns a pointer to the IGUIEditBox for access. However, is it possible to access the edit box using the IGUIEnvironment pointer instead (like via the gui control's id) ?

I would like to rotate a fairie node towards a point where the player right clicked.

According to some maths formula I've read, the approach seems to be like this:

1. Find the vector where the node is facing
2. Find the vector from the node's position to the position where the player clicked
3 ...

Its a little off topic but here goes....

If I plan to use to physX sdk for a 3D game, is it necessary to have a graphics card with certain capabilities?
My current system is uses a few years old Nvidia FX graphics card.

I'm planning to get a mac which runs an ATI radeon card. Will the physX sdk ...

bump! Great tutorial

Could there be tutorials on how to do collision detection in physX?

Looks like Bullet is a popular physics engine.

How about physX or newton or ODE? Do they have a steeper learning curve or a less active online community?

I am exploring on using a physics engine with irrlicht.
So far, the more popular and free ones are PhysX, Newton and ODE.

I have visited their websites and their screenshots look pretty impressive. As this is the first time using a physics engine, I would prefer one which
has a gentler learning ...

I would like to create a 2D game with animated animals. But it seems like Irrlicht does not support the gif format as the program crashes when I tried it out.

Is there other way to display animated 2D images?

I would like to create a scrolling line of text going from bottom to up. e.g credits at the end of the game.

How do I do that in irrlicht?

I'm trying to draw a grey 2D rectangle of size 640x480 which will appear when the game comes to an end.

I did this:


driver->draw2DRectangle(video::SColor(100,204,0,255),core::rect<s32>(10,10,200,180),0);


However, nothing appears.

Even when I changed the alpha value and changed the position ...

For my case, I use the time() method.

e.g
Note that the smallest unit of the time function is 1 second. Hope it helps

I added '\n' and it works.....thanks~

When setting text for the IGUIStaticText gui element, how do I insert a new line of text using addStatiText or setText methods?
