c# - Why it doesn't store unless when I trying to set a name for a radio button during change? -


i apologize newbie question. have 3 radio buttons in windows form application user selects 1 of them. have these 3 in group box , attempted identify string , use in message box later in code. 

string name; if (radiobutton1.checked == true){   name = radiobutton1.text; } else if (radiobutton2.checked == true) { name = radiobutton2.text; }

then have button displays message:

message box.show("welcome " + name + "how you?");

the output of welcome how instead of welcome bob how you? unless have selected 1 radio button changed , pressed different one. can please explain happening here , why displaying name if radio button changed?

might code helps 

   string value = "";    bool ischecked = radiobutton1.checked;    if(ischecked )    value=radiobutton1.text;    else    value=radiobutton2.text;     messagebox.show("welcome " + value + "how you?");

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
