Can't select the "Green Boxes"

ALRIGHT! I was finally able to replicate this in Unity v5.1.3f1. As Adam Kelm and others have pointed out, here's the fix:

1. Go to the Edit menu and choose Project Settings > Quality.
2. In the Inspector window, select the High Quality option.
3. In the Inspector window, under the Rendering section, change the Anti Aliasing dropdown to Disabled.

This is partially my own fault, because anti-aliasing doesn't work with deferred rendering, so I'm guessing it's that interaction that's triggering this issue. However, I'd also consider this a bug, because it shouldn't have anything to do with the Scene view; only the game view. Not being able to click on game objects in the scene is a really bizarre manifestation of this, and I would have never guessed it without everyone's help. Thanks for being patient and working through this!

In my opinion this a critical content fix. I'm working with our video team to correct the "Setup the Project" video where we talk about Quality Settings so that anti-aliasing is turned off. During the interim, I've added the correction to the Teacher Notes in the videos "Setup the Project" and "Place Assets in the Scene View".

Excuse me,

Solution is simple. In the upper left corner of the window above where it says Hierarchy there are five buttons. The first one is the "hand"(nav tool), the second one is the "multidirectional pointer"(position tool). If you have the "hand" selected you are not able to select items, and you need to switch to the multidirectional pointerr(position tool) right next to it. Only than you are able to select items inside the environment.

Cheers.

It did indeed! Thank you for replying fast. I was not able to follow along the videos because of it. Love the videos. Thanks again.

Some tips: You can select in "Scene" window and is not posible in "Game" windows. The "Green Box" is a physics box collider. Is use for game collision. Is attach to the game object as a component. You can select the game object by selecting it in the "Hierarchy" window. If you double click it in the "Hierarchy", it will frame (looking at the selected object). In "Scene" window, you can select also the mesh of the game object but not the collider itself. In this case you are not selecting the "Green Boxes", you are selecting the 3D mesh component. Just to let you know, If the mesh is transparent (glass) you can't select the object in a easy way. Also if there is a canvas, selection can be a problem.

You can start selecting it in the Hierarchy. For more detail info: Look the INTERFACE & ESSENTIALS, USING THE UNITY INTERFACE section link: http://unity3d.com/learn/tutorials/topics/interface-essentials

for example: Interface Overview or The Scene View link: http://unity3d.com/learn/tutorials/modules/beginner/editor/interface-overview?playlist=17090 link: http://unity3d.com/learn/tutorials/modules/beginner/editor/the-scene-view?playlist=17090

Is hard to debug why with so little info. Probably i can help if there is a video. I can try to imagine what are you doing. For example If you try to select objects in the "Game" window instead of the "Scene" windows , is not possible to select the object in the game window and can be one reason. Try to select the mesh at the center of the object using right mouse pushing one time. If you select multiple times you are deselecting all. If you select more than one time in the same place (in the scene view) it will select the objects that are in front first and later then the objects that are on the back. Is just one right click in the center of the object and not a box selection. You can make a box selection for multiple objects. And I think if you click the same object 4 times the scene camera will follow the object (if it is moving). So my best advice is to look the video manual because there can be a multiple combinations of problems or in this case make a video?

Hey Guys, I think I got it. Make sure that there's no play/pause happening on the scene. I made the mistake of dragging something earlier and clicking play. Well, as long as there's some type of play/pause, you need to stop it all the way, then your screen will act like Nick Pettit 's

If you're like me you may have it the play button at the top. And because of that I couldn't select objects like Nick. But once I deselected play (just clicked it again) everything worked normally.

Hey everyone,

When you select a game object in the Scene window, it will select the parent prefab first (in this case, the Environment prefab). If you click that same object again, it will select the individual object.

So if you're trying to move a rock around, you may need to click on it once to select the prefab, and then click again to select the rock you're trying to move.

I hope that helps!

Hey Abdullah Mohamed, Adam Kelm, and Daniel Kirwan

Do you think one of you could post a video of this happening, where you click a game object in the scene view and everything is deselected? This is really strange and I'm having a tough time debugging it. Selecting objects in the scene view in Unity is a very basic action, so I would be very surprised if this is actually a bug. There has to be something simple that I'm missing here, but I can't figure out what it is yet. :-/

Adam Kelm nailed it, at least for me.

Go to Edit > Project Settings > Quality

Choose the Low Quality mode that we set up earlier.

After doing this I can select objects in the scene view where I couldn't before.

Is not in the known issues: http://unity3d.com/unity/whats-new/unity-5.1.3

I strongly suggest to make a scene specific to debug and report this issue to Unity using unity.bugreporter.exe (Report a Problem with Unity). They fix bug each week. I will try to look and reproduce this error in the the latest final UNITY 5.2.0F2

Perhaps there are multiple causes to the same symptom. For me it was not bug related. Thanks.

I am still facing that issue even after changing the quality settings. It was working fine until after using the environment prefab. I can only select something by dragging a selection box around it which makes it frustrating. I still can't select a rock separately. When I drag on a rock it selects the whole environment. Sometimes it selects in 10 or 20 rapid clicks and sometimes it doesn't even in 50 clicks. Very frustrated right now. Version 5.3.4f1 Personal.
