qt - Crash when delete QGraphicsItem -


i want remove items in qgraphicsscene , delete them. this,

qgraphicsitem * item = null; foreach(item, scene->items()) {     scene->removeitem(item);     delete item; }

however, crashed segmentation fault after running block of codes , getting out loop. , in debug mode, debugger jumped assembly file: enter image description here what's going wrong?

if deleting items scene, why dont "clear" shown below. have scene object right.

scene-> clear();

as per documentation: void qgraphicsscene::clear()

removes , deletes items scene, otherwise leaves state of scene unchanged.

this function introduced in qt 4.4.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
