Mouse Picking

[sevans]

Hi,

I am new to Irrlicht. I have been working through the Irrlicht tutorials. There is information in tutorial 7 for picking based on the camera. How can I do picking based on mouse clicks? Is there a tutorial or reference for this? I have done it using OpenGL before so I figure it must be possible.

Thanks,

Here's an example,

Code: Select all

core::position2d<s32> mouse_pos=Device->getCursorControl()->getPosition(); 
core::line3df line=Device->getSceneManager()->getSceneCollisionManager()->getRayFromScreenCoordinates(mouse_pos, Device->getSceneManager()->getActiveCamera()); 
 
IsceneNode* object=smgr->getSceneCollisionManager()->getSceneNodeFromRayBB(line);

Ah that makes perfect sense.

Get the mouse coord on screen, use a ray and the col. detection system to find out what is the first object at those coords on the screen.

Thanks a bunch raven_coda
