Irrlicht Engine

hi,jp i have a question(problem?) i try example of cloth,i set device is d3d9, load texture can't show flag. look img 1. log say: Could not get lower surface level for mip map generation i change to default opengl, texture is good look img 2. why? my display card is 8600m img1: http://www.reqi.com/d...

i will read a xml file,file encode is unicode 16le. i compile have error: 1>main.cpp 1>e:\code\project\xmltext\main.cpp(33) : error C2664: 'const irr::io::char16 *irr::io::IIrrXMLReader<char_type,super_class>::getAttributeValue(int) const' : cannot convert parameter 1 from 'const char [8]' to 'int' ...

maybe model design no position on world origin. i want know model and world origin length. someone can try my model. tell me how to know? my code: nodes[k] = smgr->addAnimatedMeshSceneNode(smgr->getMesh(modelfile.c_str())); // nodes[k]->setScale(StrToV3df(scale)); nodes[k]->setMaterialTexture(0, dri...

ObjNodes->getAbsolutePosition();

reutrn Position always (0,0,0).
not my want.

I load some meshs, one like a stick, other like ball.

i want take a stick to touch balls.

question:

how can i know which one ball is touch?
i have a collision.
but i don't know stick touch ball is.....

thanks nathanf534!

getAbsolutePosition is self origin or world origin?

and,i load a node, getAbsolutePosition and getPosition return value is equally.

how to i get a node position return from world origin?

because i load a node default position no in world origin(0,0,0).

thanks.

getAbsolutePosition() and getPosition() return values difference.

thanks!

Code: Select all

use IGUIElement::getType () to be certain.

yes!

thanks you!

yes,i found irr API doc

root->getElementFromId(postdb->CS32List, true)->
no setChecked(bool) function.this function is under class IGUICheckBox

i no found function return is IGUICheckBox,except addCheckBox() .

i want reset a form, like web form's reset. code: void UIControl::ResetLoginForm(PostData* postdb) //Clear All EditBox & CheckBox values { IGUIElement* root = guienv->getRootGUIElement(); for (int i = 0; i < postdb->CS32Lenth; i++) if (root->getElementFromId(postdb->CS32List[i],true)->getType() ...

you should return false at the end of your event receiver if you haven't handled the event, that way it then gets passed onto things like cameras and the gui, otherwise they don't get it. So if you handle the event and don't want the rest of irrlicht to get it return true, otherwise return false. o...

yes,i sure i have a IEventReceiver in my code. when i click the button, no everything button event. only mouse event. And could we see your event receiver? of course! bool UIControl::OnEvent(const SEvent& event) { if (event.EventType == EET_KEY_INPUT_EVENT && event.KeyInput.Key == KEY_E...

yes,i sure i have a IEventReceiver in my code.

when i click the button, no everything button event.

only mouse event.

i use guienv->addButton() create a new button. i can see but can't click it. why? if (stringw("Button") == xml->getNodeName()) { x = xml->getAttributeValueAsInt(L"x"); y = xml->getAttributeValueAsInt(L"y"); w = xml->getAttributeValueAsInt(L"w"); h = xml->getAt...

why nobody answer me?
