[SOLVED] Picking but not correctly...

[Linaxys]

Hello,
I try to pick an object like this everytime I click on it :

Code: Select all

		ISceneNode *sel = cynScene->getSceneCollisionManager()->getSceneNodeFromScreenCoordinatesBB(cynDevice->getCursorControl()->getPosition(),0);
		if (sel && sel != planeNode && sel != skybox && sel != cynCamera && sel->getID() == OID_OBJECT) {
			printf("ITSOK\n");
		}

I set my breakpoint on the printf, and the debugger break here ONLY when I pick very near the center of my mesh... If I try to pick an edge and a little closer, it doesn't pick...

How can I pick on every point of a mesh please ?

it sounds like you bounding box isn't the right size.

getSceneNodeFromScreenCoordinatesBB gets mesh from the Boundig box (BB)

using getCollisionResultPosition or getCollisionPoint does collision detection on the triangles

Sorry for the disturb, it was for a browser plugin and I forgot that the Irrlicht's screen position was badly positionned from the original HWND handle.

To fix that I was just using the GetCursorPos and ScreenToClient function to get the real cursor position instead of getCursorControl()->getPosition().
