Irrlicht Engine

The CGUITTFont class comes from http://irrlicht.sourceforge.net/forum/viewtopic.php?t=39026

But even i use built-in font, the same problem will occur.

I paste a full example to display this, which is adapted from Irrlicht example 18(Split view)

Hello,

I try to add some TextSceneNode to Scene manager.

In a single view, the text can be displayed correctly including English words and Chinese words.
When I use two views, the graphics can be displayed correctly , I means it keps correct width-height ratio.
But the text display has a ...

I want to choose a color by this IGUIColorSelectDialog.
I try to use env->addColorSelectDialog
And I can see the color select ring

But I can not select the color on the ring, and I dont know how to get the returned color value?

Anyone can help me? thank you .

Yes, I can define the aspect ratio based on the view size

But after I set the aspect ratio directly, I can not see anything.

I don't know What kind of effects it will bring to my camera.


//設備種類

I want to use the same camera for both one view display and two view display.
(someone use different cameras for single view and two views, but here I want to use the same one)

So when I switch from single to two views, the width/height ratio becomes strange.

I try set the aspect ratio of camera ...

Sir

By Mr. cheshirekow's suggestion,

I have put one empty node in the scene as the parent for all cameras

//create the camera target empty scenen node;
camtarget=smgr->addEmptySceneNode();
//set its innitial position to (0,0,0)
camtarget->setPosition(irr::core::vector3df(0.0f,0.0f,0.0f ...

As my box is aligned,
I will try Mr. DavidJE13 's method

It is simple than I imagine before

Thank you all very much

I have a core::aabbox3df box and a vector3df point

How can I get the nearest distance between them?

I can get center of the box by function　getCenter()



Than you for your suggestions

Sorry, I have found the answer in this forum.



child->setMaterialFlag(irr::video::EMF_LIGHTING,true);
setMaterialFlag(irr::video::EMF_LIGHTING,false);
getMaterial(0).EmissiveColor=RAY_LINE_OFF_COLOUR;
child->getMaterial(0).EmissiveColor=RAY_LINE_OFF_COLOUR;


One more point should be ...

I want to make a sensor, which has a small cylinder and a long pin in the front.

I want to set the color according to the member variable isON is ture/false.

But I found it can not make any effects whatever I change the color.

Because in my scene I have many other bodies which need not lights ...

That means I can set it to NULL if I need not it.

Thank you very much.


It is an out parameter. You get a reference to a pointer for an unchangeable ISceneNode. You pass in "outNode" which is declared like this:
const scene::ISceneNode* outNode = 0;

Check ISceneCollisionManager.h for a more up ...

I have a question when I use ISceneCollisionManager.

I use ISceneCollisionManager::getCollisionPoint(ray, collisionTriangles, point, triangle)

The compiler tell me it need five parameters

Though the document http://irrlicht.sourceforge.net/docu/classirr_1_1scene_1_1_i_scene_collision_manager.html ...

En It seems that I have to do this.

Thank you Acki, vitek very much

I want to put the target of my camera at the center of the total models which include many many scene nodes.

Should I scanning each scene node and its child node by myself? Or, Irrlicht has provided a function like this?

getRootSceneNode()->getTotalBoundingBox()

Thank you for your comments.

Thank you for your explanation.
To clarify the question more clearly, take the following drawing as an example.
The origin of the world coordinates is at O point (xog,yog,zog)
The object A is mounted to scene node root with local coordinates(xl,yl,zl)

So when I rotate the scene node O' by a free ...
