How would I go about playing an animation backwards?
I've tried giving the animation handler negative delta but that just stops it. Subtracting the delta from this.currentTime of the animation doesn't work either.
Any ideas?
Since Three.js r69 it's possible to play animations in reverse order by setting animation.timeScale = -1 though only when animation.loop = true.
See Reverse animation, feature request #5062 for more updates.
I am using r126
Set action.loop = THREE.LoopPingPong will play the clip with the choosen number of action.repetitions, alternately playing forward and backward. (doc)

So I am working on a game at the moment and I made an animation that I would like the player to use while walking, I'm having an issue where when the animation plays my character stops moving it's legs and arms. Here is the code that I am using to run the animation, I did not include any variables in it.
AnimTrack = plr.Character.Humanoid:LoadAnimation(Anim)
AnimTrack:Play()
You can't if both animations use the same body parts (even if they do not move them).
The only way to combine animations is to use animations that don't use the same bodyparts (have those disabled which are used by the other animation).
Ideally create your own animations to avoid any unwanted effects.
In my React Native application I have some tiles (wrapped in a View for the example) which are half of the full width wide. They act as buttons and slide to the opposite side to open a menu. When I perform a swipe gesture and release the finger before the slide reaches its final position, I want the slide to animate to its final 'opened' position. The animation should start with the last velocity of the touch gesture for a smooth impression.
I implemented different variations but did not find a good solution (You can find my test-component in my GitHub repository). My View has a PanResponder to manage the gesture and to get the velocity. I started to use the Animated library, but the provided methods do not solve my problem. The only method where I can pass a initial velocity for the animation is the decay, but I can't pass a parameter where the animation should stop. With a timing animation I can set a final value, but can not pass a initial velocity (so the animation starts with a velocity of 0 which looks very jumpy). I tried to combine these two methods, but that does not work properly.
On iOS I could use a horizontal ScrollView with pagingEnabled, which shows the desired effect - but then I do not have the feature on Android.
Any ideas how I can solve this problem and show a smooth animation, starting with an initial velocity and ending on a given position, after the touch gestures end?
Thanks for your help!
EDIT I added the link to my last test component...
You can get a close approximation of the velocity by setting the duration of the timing animation
const duration = Math.abs((this.props.MAXDISTANCE - Math.abs(distanceMoved)) / velocity);
MAXDISTANCE is your final position
distanceMoved is the current position (gestureState.dx)
velocity is the current velocity (gestureState.vx)
You can use Animated.decay or Animated.spring to achieve this effect.
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.
Simple Animation - first thought that came up, when 2 objects collided.
For example: Player collides with object Bouncer. What would happen?
Player class start bouncing animation
Bouncer class start self animation to inform user that bouncing started
this is simple animation that looks pretty good but, I have an idea how to add more realism to this and i want to, ask is it really possible to do this?
Let's say same situation player collided with bouncer
Make player invisible
In Bouncer class start animation (animation frames painted with Player and Bouncer motion (e.g preparing for jumping))
in step 2 Players position changed, putting players into position where bouncing animation ended
Make player visible
start Jump
If it is really possible, then i think this will look more realistic. Is there any sample code for this?
Animating anything in Cocos2D can be very time consuming. If you are doing vector/pixel work, you must create a frame for every single change in the animation, which can be very challenging if you don't have much in the way of an artistic background. Might I recommend something like Adobe Flash which will semi-automate the animation process. It has a function to export the animation to frames (individual PNGs), which could be turn into an animation using CCAnimation and some helper classes.
You can create your animation using After Effects, for instance, that generates a set o frames. Then you can use a software like Sprite Helper to embed that animation in cocos2d.
On your project you just have to load it and play it when you need.

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.

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