I'm currently building a 2d platformer and encountered a few problems.
My player has a script so that when the player hits a cube with a rigid body, the cube can be pushed. When the character pushes the object, the regular walking animation is displayed.
I want to play the pushing animation at that moment but cant seem to fix it. I read a lot of topics on the internet about the difference between unity new Animator editor and the older versions.
Is there a simple way to trigger the animation on hit, and how do I have to add it in the Animator? Also with witch states should it be connected?
Found it on google, maybe it will help

He uses a Layer for the animation of the cannon so he animates regardless of the body animation.

I have written a game in SpriteKit using objective C and it works perfectly on ios9 but it looks hideous on ios8. I would really like to know how to fix this problem, either by “correcting” my mistake, or if I have no mistake then by finding a workaround for the bug in ios8.
I think I have really done all I can to make the problem as clear as possible, including making loads of screenshots to illustrate the problem and also making a new Xcode project that is as simple as possible while still showing the problem.
If you want to try the Xcode project, here is a link for it….

If you want to see the screenshots of the problem, then here is a link for the screenshots.
Screenshots
Now I will try to explain the code I wrote and the problem illustrated in the screenshots.
PLEASE REMEMBER: My code works perfectly on iOS9.3. So my code is obviously not complete gargage. But admittedly, I am not an expert on handling screen rotation, so probably my code could be better.
I should probably mention that both scenes have scale mode set to SKSceneScaleModeResizeFill. I chose this mode because I had tremendous difficulty doing proper layouts for all possible screen sizes (including iPhone) when working with SKSceneScaleModeAspectFill. I do I hope I can solve this problem while sticking with SKSceneScaleModeResizeFill.
Anyway, my app is a SpriteKit game with two scenes. The main scene is the GameScene, where you play the game. And this scene has a pointer to the SettingsScene, where you can change the settings of the scene. (e.g. change the level of difficulty).
Anytime the user rotates the screen, GameViewController detects this change in viewWillTransitionToSize and tells the GameScene object about the new screen width and screen height. Game Scene then adjusts the positions of its sprites in consideration of the new screen orientation and then tells its SettingsScene object about the new screen width and height to that the Settings scene is properly laid out as well.
Please note that with this design, all sprites on BOTH scenes get repositioned any time the user rotates the screen REGARDLESS of which scene is actually active at that time..
As I said before, all works as expected on ios9.3. But on ios8, the result is attrocious. The screenshots illustrate one example of typical experience on ios8. If the user rotates the screen while using the game and then goes to the settings screen, he will see something awful. And will often be trapped in this terrible experience because the button for going back to the main game might not even be fitting on the screen anymore.
At first, it might seem like I am failing to reposition sprites for landscape mode in the settings scene. But this explanation is wrong. The text on the screen shows that the last layout was performed with the landscape orientation in mind.
So what is going wrong here?
Any suggestions would be highly highly highly highly appreciated.
Thanks!

p.s. In case you don't want to look directly at the linked project file, here are some details about the example code. GameViewController implements viewTransitionToSize to handle any screen rotation. It directly tells the new screen dimensions to GameScene, which then tells SettingsScene. Both scenes rearrange their sprites in consideration of the new screen dimensions. And all goes well on ios9. On ios8, however, the inactive scene ends up looking hideaous when it is presented even though it clearly did reposition its sprites according to the new dimensions.
the problem is easily resolved by these lines....
gameScene.size = newScreenSize;
settingsScene.size = newScreenSize;
anytime the orientation changes.
This code is not required for ios9. The scene knows what size the screen is without assistance. But for ios8, it seems to be needed to add this code.
When I play animation which change offset polygon collider 2D the gameobject with animator destroy itself in hierarchy for no reason. When I remove collider offset the animation start working properly once again but without collider it's unusable for the game. Until this day it was working properly but suddenly it has broken for no apparent reason. I haven't change animation in any way. Only thing I did was importing Google Play Service and installing some SDk's. I was trying to find solution the whole day but came up with nothing and now I am desperate.
I am new to designing games and have been having trouble for the past couple of days with the animator. I have downloaded a free asset off the Unity store that included a free sprite character and also its animations for idle, walk, run, and jump. My issue is when I go to use this asset pack in my game, I can not for the life of me figure out how to transition between idle->walk, and any state->jump. I believe it has to do with no parameters being set up, as I want the walk animation to occur when my character is moving. The issue is that it seems to be stuck in idle mode. In the animator the transitions are set up, but I can not figure out how to let the animator know when I am moving, and when I am actually idle. How can I connect my characters movement scripts to be used in conjunction with the animation? Do I need to write a new script, that uses new parameters I make in the animator, or am I completely missing something? Again I am very new at this, so I apologize if this is a dumb question but I cannot figure it out. All the videos I have watched only show how to build the animations and put them into the animator, and nothing about the scripts or parameters in specific. Thank you!
Look at the animation transition requirements, then set the required values. For example:
Animator anim = obj.GetComponent<Animator>();
anim.SetTrigger("running");
or
anim.SetFloat("speed", 2);
or
anim.SetBool("running", true);
One small thing that could be going wrong: If you somehow have a reference to the prefab instead of the instantiated object in your scene, it will not work. And to be sure it's not working, play the game, find the object with the Animator in the Hierarchy, click it, and open the Animator window. You can see which state is active.
If this doesn't help, can you describe the transitions in more detail?
I am trying to achieve an effect similar to one of the cardboard app examples that Google has put out with their cardboard app called the 'exhibit'. I have a 3D object that I want to rotate using device orientation control. Right now with just the device orientation control, I can view the 3D object but when I turn around, the camera rotates (it seems) causing the object to fall out of view until I turn all the way back around to where it was in the beginning. In other words the camera seems to rotate in its axis as I look around. What I want is to be able to rotate the object as I turn around.
Kinda like this example http://threejs.org/examples/#misc_controls_orbit except I want to rotate using device orientation control.
Any idea how I can incorporate this feature?
Thank you for your assistance.
The answer to my own question for future seekers is to replace camera in
controls = new THREE.DeviceOrientationControls(camera, true);
with the 3D object you are trying to rotate.
This appears to be such a common problem, that finding answer to my specific case is near impossible, because of the amount of noise in google or forum searches.
I have imported object to unity from blender. This objects had smaller objects inside it. Those smaller objects have animation on them, which was created in unity. If I open the animation window (Window->Animation) and press play - I can see correct movement of an object. Animation is set to play automatically in inspector, culling type is always animate. If I play the game however, animation does not play. Why?
add the animation to the main object, then animate the smaller object...
you have to put animation component to main object, then animate the small part...
it is important...
it should work
I Could not find any unity inspector based answer. For now, the best option I have is to create new script, and in update() check if the animation is playing. If not, play it. Very inefficient, so to whoever might stumble upon this post in the future, I suggest you try to add this.animation.play() in setting up part of the script.
I know it's kinda late, but this is for others having this same issue.
Animations in Unity have types (2 of which I know).
Type 1 can be attached to an object using the Animation Component.
Type 2 can only be used in Animators (Mechanim).
Animations imported with FBX files are type 2 (and as far as I know, animation type in FBX files can NOT be changed), so they will usually not work when attached directly to an object with "Animation". They should be used with Animators and Animator Controllers. Just create a New Controller and add the animation. It will become the default animation state and play automatically.
If you want it to loop, click on the FBX asset, and in the Animation tab, choose Loop Time and click Apply.
