I’m using multiple animation in blender (multiple Dope Sheets )
And I’m trying to animate an arm that have an inverse kinematic constraint attach to it. But sometimes I don’t want use it, so I set the influence to 0.
The “problem” when I do this it propagates the changes to all previous animations even if the channel is protected.
Anyone knows a some way to get around this situation?
In blender almost any value can be keyframed, not just the location, rotation and scale of bones and objects. Any value that can be keyframed can also be controlled by a driver.
You can keyframe the influence value of the constraint the same as any other displayed value. Key it at 0.0 or 1.0 on the first frame and it will stay that way for the whole action. You can also keyframe it to turn on/off during the animation.
You can either RMB on a value and select insert keyframe or press I while the cursor is over the value.
The problem is if I have two animations ( animantion1 and animantion2 ) that when I turn off IK constraint in animation2 it also turns the IK in the animantion1 and it mess up with the previous animation.
I discovery that what I was trying to accomplish is the same of use FK/IK in the same animation.
The solution is instead insert keyframes with location and rotation LocRot, insert the keyframes with Visual LocRot.
Get the idea form this tutorial It explains it around 14:42.

I am trying to play an animation when a scene is instanced. It is a simple animation that translates y from -5 to 5. The animation plays but it plays at x = 0 and z = 0. I understand this is because the translation values for the respective co-ordinates in the animation are set to 0. I have a spatial node on my player scene that can grab transform info and pass it on to my animated scene, but I do not know how to dynamically change the x and z values of the key frames in script.
This answer contains three solutions to the problem...
Target a sub-property
If I understand correctly you want to animate only the y coordinate, and leave the other coordinates unchanged. That is, you don't want to animate the translation vector. You want to animate the y or the translation, a sub-property. This is possible out of the box, but the UI won't offer it to you.
Start by creating a track from the animation editor. You click on "Add Track", select "Property Track", and then on the object you want, and select translation. Now, while the track is empty (no key frame inserted yet), modify the track name to :y at the end.
The track would have been create with a name such as SpatialNodeName:translation, you are going to change it to SpatialNodeName:translation:y.
Afterwards, when you add key frames, they will be for translation.y. Note: doing SpatialNodeName:transform:origin:y or even SpatialNodeName:global_transform:origin:y also works. Similarly, you can imagine how do it for only rotation or scaling, and so on.
Create custom properties and animate them
I'll also mention that another option is using a Tween node (which are easier to create from code).
And also that both Tween and AnimationPlayer can animate any property. Thus, if you need to animate something that is not available, consider adding a property (see setget).
For example:
export var y:float setget set_y, get_y
func set_y(new_value:float) -> void:
transform.origin.y = new_value
func get_y() -> float:
return transform.origin.y
Then you can add a track for the custom property, and animate it like any other.
By the way, also notice the AnimationPlayer can also have "Call Method" tracks.
Modify the animation
Manipulating an animation from code is also possible. I've seen an example elsewhere. You can call get_animation on the AnimationPlayer to get the animation. Then on the returned animation you can call track_get_key_value and track_set_key_value. However, this rarely what you want to do in practice (unless you are making a Godot addon that creates or modifies animations or something like that).
I have an animation for humanoid models to simulate climbing. I have been looking for a way to stimulate this animation when the model comes next to the window. I used the triggers to determine where the model is and it worked. However, when I execute the animation, the position of the model is not being updated according to the animation. I am using offmesh links and nav mesh agent and I disable nav mesh agent when the model triggers. How can I use the animation and provide the update simultaneously?
Animation Properties
Thanks in advance.
I don't think the animation should take care of the movement. You should control that somewhere else. You could make the animation climb from y = 0 to 5 but then it won't work if your ladder is at y = 3.
You'd better have a method that is called from the animation using AnimationEvent so that when you trigger the animation, it also triggers a movement of the object upwards/downwards regardless of the current position of the object. It would simply use Translate and disabled input until the animation ends.
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.
I am working on a program, that uses THREE.RollControls, when the user goes too far away from the center of the screen, they tend to get lost, so I am working on creating a function that reorients them, facing the center of the scene.
What I had intened to do was simply call the following:
camera.lookAt(scene.position)
However, this has no affect. From what I was reading on different stack overflow questions specifically this:
ThreeJS camera.lookAt() has no effect, is there something I'm doing wrong?
It seems like their solution was to do the camera position change using the controls, rather then changing the camera itself.
I do not believe there is any 'Target' in the Roll Controls, so I don't know how I can reset where the camera is looking at based on a THREE.Vector3() Is there a simple way to do this, or will I basically have to:
So far I have 'attempted' to do the follow:
- Calculate the difference of position of the camera with the position of the scene.
- Normalize this vector
- Subtract it from the direction forward of the camera
- use this vector in controls.forward.add(thisVector)
but this doesn't do at all what I want (probably because I have no idea what I'm doing)
Thank you in advance for your time!

The same thing bugged me too about the RollControls but I took a different approach in solving the problem. Since the controls are in the example code (in r55) you can modify the controls, as they are not part of the core library. You can see my modifications at http://www.virtuality.gr/AGG/EaZD-WebGL/js/three.js/examples/js/controls/RollControls.js
I introduced a local variable called mouseLook because I could not use the this.mouseLook. I initialized it to false and I only make it true when there is a button press i.e. when navigating in the scene. That solved my problem.
Coming from the iOS world where we have UIImageView and the property animationImages:
http://developer.apple.com/library/ios/documentation/UIKit/Reference/UIImageView_Class/Reference/Reference.html#//apple_ref/occ/instp/UIImageView/animationImages
Where animationImages is just an array of arbitrary animation frames. You specify the images (maybe 15), then set the total animation time (maybe 4 seconds) in one of the other properties, then just start the anim and the images in animationImages will play sequentially over the specified time with an even frame rate.
How would I do the same with WP7/Silverlight? This all Expression Blend seems wonderful, but I just can't find a way to animate the image source (I'm guessing it might be impossible). How would I do the same? Should I add a unique image object for each frame in the animation, then play around with visibility/opacity properties and manually have to create all the spaced out key frames? That sounds like a lot of extra work + overhead and not a nice way to go...

Try out these links. Especially the first one, I think the first one resolve all you doubts. In wp7 we can go for two options either XAML based (static) animations / or with the help of C# code. By using blend u can create all sot of static animation with out any issue. Here the animation is working on the basis of page frames. If u are interested in learning more about Animation try this too;

You can actually animate the Image.Source property here's a tutorial.
