How to remove animation from object in raphael?
var animation = Raphael.animation({opacity:.2}, 1000);
var circle = paper.circle(0, 0, 5).animate(animation.repeat(Infinity));
I want to perform animation on object until some moment in time. And the question is how to remove/stop animation in that specific moment?
Well, I really don't know why, but the fiddle works if don't pass any arguments to the stop method. Despite what Raphael's documentation says, I found a working example of an animation stopping in this site (is not the most beatiful site, by the way, but they have an example for each raphael method!)
Here you have the Fiddle working. http://jsfiddle.net/fKxqS/2/
Enjoy!
If you want to stop the animation after a specific timelapse...
setTimeout(circle.stop(animation), 500) //500 is milliseconds, so it's 0.5s
If you want to stop the animation after an event, such as a click
circle.click(function(){
circle.stop(animation)
})
Edit: Seems Raphael doesn't stop if repeat is set to Infinite, perhaps somebody knows a workaround, here's the fiddle: http://jsfiddle.net/fKxqS/

So I'm making a button for a "New Note" in Swift UI similar to the Apple Notes app.
Right now my "New Button" is a "Navigation Link" like so:
NavigationLink(
destination: EditorView(makeNewNote())
) {
Text("New")
}
Unfortunately—this triggers my app to create a new note every time the view loaded. :(
:/
I've been looking for a way to initate a segue on button push but I'm not finding success on this yet.
When I tried a modal—I found myself having the same problem
Button("New") {
self.isNew = true
}.sheet(isPresented: $isNew, content: {
EditorView(makeNewNote())
})
I'm wondering what the best way to approach this would be.
Having no success :(
Edit:
I referred to this and the documentation but I haven’t found a way to segue via a button push which would be ideal. (The function dosent get triggered in the closure :)

Also...if you were curious what makeNewButton() does—it basically inserts a new Core Data object into my app’s managed context.
I'm not entirely sure, but it kinda sounds like to me your problem lies in your model. Because each time your View loads it calls the makeNewButton() function right?
Maybe you can fix the problem by displaying the "new note" view and having an extra "Save" button that only makes changes to your model once it's triggered.
Alternatively, you could use context.rollback() to discard changes. Also, check out this Project. It's Beta 4 but works just the same and imo is a good example how to use CoreData with SwiftUI. :)
According to most Famo.us tutorials, you only need to add the following line to make Fastclick work (Famo.us university Timbre project)
var FastClick = require('famous/inputs/FastClick');
However, I have found that that alone doesn't kill the 300ms delay in an iPhone 5. Is there any additional configuration to be done? I included the FastClick line for the following code:
this.accordionSurface.on('click', function() {
this._eventOutput.emit('editItem', this.model);
}.bind(this));
This is part of a AccordionView that is then added to a Scrollview through a ViewSequence (copied from the Taasky demo at https://launch-demos.famo.us/Taasky/). However, unlike the demo, tapping on my items takes some time to react. The animation done after tapping on my item looks like this:
AccordionView.prototype.hide = function(scrollView) {
this.accordionModifier.setOpacity(
0,{ duration : 100, curve: 'easeInOut' },function(){
this.size.set(0.001, {duration: 300, curve: 'easeOut'}, function(){
}.bind(this));
}.bind(this));
}
The animation works fine and smooth, but it's triggered with a bit of delay that I assume comes from the lack of the FastClick integration. I had moved the require line around the AppView, main.js without result and I have yet to find an example that does anything else that calling FastClick with the require line.
Any hints?
It's not exactly a fix but we've noticed that the 'touchend' event (or 'end' event in a GenericSync) fires reliably and could be used as an alternative to click with a bit of tinkering.
This time I would like to ask if anybody had such strange problem with disabling button (CCMenuItemImage) in cocos2d. I have in-App-Purchase connected and when purchase is done following function is triggered
- (void)productPurchased:(NSNotification *)notification {
[NSObject cancelPreviousPerformRequestsWithTarget:self];
waitingForStore = FALSE;
[loop setVisible:FALSE];
[buyItem setVisible:FALSE];
// setAccessibilityElementsHidden:YES];
NSString *productIdentifier = (NSString *) notification.object;
NSLog(#"Purchased: %#", productIdentifier);
}
waitingForStore = FALSE;
[loop setVisible:FALSE];
This two operation works fine, but the problem is with the third one. I would like to make the 'BUY' button invisible.
[buyItem setVisible:FALSE];
This one does not do anything at this place( the button is still visible and accessible). If I will use it on the other part of code it works just fine- but here .... not. Trying to change position doesn't work neither.
Could it be connected with inAppPurchase thread or something?
I have found the reason. It was my mistake when making two calls to the apple store and creating two buttons. :) So, it could be closed.
I understand your problem. If you you want to disable menuitem you can set menuitem.isEnabled property.
And if you want to hide button, you can set property menuitem.visible = NO.
If this is not working for you can also use [menuitem runaction:[CCFadeOut actionWithDuration:1.0f] ]. Then use FadeIn as per your requirement.
This is alternative option for you.
I'm getting stuck to implement some Cocos2D animations for my Tetris clone(that works perfectly, no logic bugs, i just want to perform some smooth animation when deleting rows).
The current code(no animation) just drops the block position, like this:
block.position = ccp(block.position.x, block.position.y - kBlockSize);
This happens in a for loop for, classic tetris programming. But when i try to animate, like this:
id move = [CCMoveBy actionWithDuration:0.5f position:(0, -kBlockSize)];
[block runAction:move];
Some blocks just moves down once, even tough the action may be called multiple times for the same block(when breaking more than one row for example)...
Why that happens ? I know it's a little bit confusing, but the point is that i'm doing the same stuff and getting different results...i could post more code to help clarify!
Thanks!
I'm quite sure actions are parallel operations so you could be calling a CCMoveBy action before a previous one is completed. Some alternatives I have used are...
Monitor for when the action completes by using a CCSequence finishing with a CCCallFunc action that sets a flag. Something like...
id myAction = [[CCSequence runWithActions:[CCMoveBy actionWithDuration:0.5f position:(0, -kBlockSize)], [CCCallFunc actionWithTarget:self selector:#selector(myFunc)], nil]
Roll your own solution using a velocity variable in a tick or update function where you can get a hold of delta time/# of ticks since the last update
Hope some of that helps.
Thank you guys, those answers help me a lot!
I've tried CCSequences before posting here, but without success.
The problem was the following:
Inside the CCSequence that deletes a row, i have 2 actions: the first one fades out the entire row of blocks(duration of x seconds), and the second one drops all the blocks above the row(duration of y seconds).
This works fine if ONLY ONE row needs to be deleted, because if there is more than one row, the next CCSequence starts nearly the same time the previous, reading a incorrect position of the blocks above, leading to a incorrect cascade of blocks.
I solved that using a longer CCSequence, that takes a CCCallFuncND as the last argument:
id fadeOutSequence = [CCSequence actions:fadeout, destroyBlocks, notifyFadeFinish, nil];
//inside method specified for notifyFadeFinish:
id dropAbove = [CCSequence actions: dropBlocks, notifyDropFinish, nil];
//inside method specified for notifyDropFinish
//start a new delete sequence, if there is more rows to delete.
Now going to implement gravity mode, thanks again!
I'm using Cocos2d to write game for iPhone.
Here's the problem.
I have CCSprite and CCAction which is run on it.
CCSprite texture;
CCAction anim_action;
"Anim_action" is a CCRepeatForever action.
Now I want to check if this animation is running.
First I though I can use [isDone] function, but I think it doesn't work on CCRepatForever actions (I'm not sure - this opion is based on my tests)
So how to check if this animation is already running on my "texture"?
Maybe there is a way to get name of action which is running on texture at the moment?
It may be also useful!
There is a way to check if a specific action runs on your texture. Use:
CCAction *action = [texture getActionByTag:kAsignedActionTag];
where kAsignedActionTag is the tag assigned to the your animation.
anim_action.tag = kAsignedActionTag;
If your action is still running the getActionByTag method will not return nil.
I don't believe there's a way to directly tell if a CCRepeatForever action has completed since the isDone would make no sense, but there are some techniques you can use to essentially provide a callback to indicate if something is still running:
Override the step: method and call out to something that checks the interval - when it exceeds a threshold you can assume completion...kinda'
Wrap the inner action of the CCRepeatForever with a CCSequence. The first action of the sequence would be your repeated action and the second would be a CCCalFunc, again indicating that the action is still running
Subclass the CCRepeatForever and override the dealloc so you can fire a callback when the action is killed and released
You can easily use [isDone] while appling an effect
- (void)shakeThatThingOn: (BOOL)on { //you can return BOOL and get if the animation is working or not
if (on == YES){
id shaky2 = [CCShaky3D actionWithRange:3 shakeZ:NO grid:ccg(15,10) duration:5];
if (![shaky2 isDone])
[self runAction:[CCSequence actions:shaky2,[CCStopGrid action],nil]];
}
else {//this else is being called when you turn off animation (it's just 0.2s continuation after turning off - for better visual effect.
[self stopAllActions];
id shaky2 = [CCShaky3D actionWithRange:3 shakeZ:NO grid:ccg(15,10) duration:0.2];
[self runAction:[CCSequence actions:shaky2,[CCStopGrid action],nil]];
}}
and control it by simple BOOL if it's on or off.
I don't know if it's what you mean, but hope it'll help anyway.
If you know how many actions will be running on the sprite, or if the animation is the only action, then you can infer that the animation is running by checking the sprite's total number of running actions.
if ([texture numberOfRunningActions] > 0) //animation is running
or
if ([texture numberOfRunningActions] > someNumber) //if you had other actions running
