I want to create a scale-up and scale-down animation the first and last 7 frames of my layer. Is there a way to create an animation preset for this?
Thank you!
Solution:
startScale = [0,0];
endScale = [100,100];
nombre_capa = "layer_name";
if(time < (thisComp.layer(nombre_capa).inPoint+thisComp.layer(nombre_capa).outPoint)/2)
ease(time,thisComp.layer(nombre_capa).inPoint,thisComp.layer(nombre_capa).inPoint+0.2,startScale,endScale)
else
ease(time,thisComp.layer(nombre_capa).outPoint-0.2,thisComp.layer(nombre_capa).outPoint,endScale,startScale);

as the Toolbar or Titlearea on scroll animation feature is referenced in the last section of the Toolbar API, and also in this great video tutorial (starting at about min 45), the animation works well under given circumstances.
I was not able to find any documentation about what these have to be, however I found one circumstance, in which it does not work. Here is a working example to demonstrate the problem:
Form hi = new Form("Title", new BoxLayout(BoxLayout.Y_AXIS));
EncodedImage placeholder = EncodedImage
.createFromImage(Image.createImage(hi.getWidth(), hi.getWidth() / 5, 0xffff0000), true);
URLImage background = URLImage.createToStorage(placeholder, "400px-AGameOfThrones.jpg",
"http://awoiaf.westeros.org/images/thumb/9/93/AGameOfThrones.jpg/400px-AGameOfThrones.jpg");
background.fetch();
Style stitle = hi.getToolbar().getTitleComponent().getUnselectedStyle();
stitle.setBgImage(background);
stitle.setBackgroundType(Style.BACKGROUND_IMAGE_SCALED_FILL);
stitle.setPaddingUnit(Style.UNIT_TYPE_DIPS, Style.UNIT_TYPE_DIPS, Style.UNIT_TYPE_DIPS, Style.UNIT_TYPE_DIPS);
stitle.setPaddingTop(15);
// hi.setLayout(new BorderLayout()); // uncomment this for the animation to break
Container contentContainer = new Container(BoxLayout.y());
contentContainer.setScrollableY(true);
// add some elements so we have something to scroll
for (int i = 0; i < 50; i++)
contentContainer.add(new Label("Entry " + i));
hi.add(contentContainer);
// hi.add(BorderLayout.CENTER, contentContainer); // use this line instead of the above for the animation to break
ComponentAnimation anim = hi.getToolbar().getTitleComponent().createStyleAnimation("Title", 200);
hi.getAnimationManager().onTitleScrollAnimation(anim);
hi.show();
With my current app and the codesample from the Toolbar API (which is roughly adapted here), I found out that the onScrollAnimation event is not being called, when a scroll occurs inside a BorderLayout. Even when I have a separate container, which is not the contentpane itself, and I set setScrollableY(true); to true, the animation works properly. The animation stops working, when this very container is put into Center of the Form, via Borderlayout. in the example above, the layout is exactly the same, as there are no other components in other areas of course, but it breaks the animation.
How to solve this? In my app, I have the need for a BorderLayout but still want to use this cool feature. Also, this is a very un-intuitive feature, if it works for some, but not all layouts. It should be completely layout-agnostic and work in every case.
Thank you.
The adapter is bound to the forms content pane scrolling so it won't work if you have a border layout in here. In that case scrolling isn't detected because the code just isn't aware of the scrolling. It would need to track the scrolling of any component in the UI to detect that scrolling.
as hinted by Shai, the solution is the following:
hi.setLayout(new BorderLayout());
Container contentContainer = new Container(BoxLayout.y());
contentContainer.setScrollableY(true);
// add some elements so we have something to scroll
for (int i = 0; i < 50; i++)
contentContainer.add(new Label("Entry " + i));
hi.add(BorderLayout.CENTER, contentContainer); // use this line instead of the above for the animation to break
ComponentAnimation anim = hi.getToolbar().getTitleComponent().createStyleAnimation("Title", 200);
hi.getAnimationManager().onTitleScrollAnimation(contentContainer, anim);
instead of using the onTitleScollAnimation to just add the animation, provide your own scrollable "body" or content container as the first argument, appended by the animation(s).
I am making a metronome app and I need to pan one metronome to the left and another to the right. I know AKMetronome class has no pan property, but can anyone suggest I can accomplish this?
let mixer = AKMixer(metronome, metronome2)
AudioKit.output = mixer
try AudioKit.start()
metronome.start()
metronome2.start()
Above code works but two metronomes are both centered. Thanks.
AKPanner will do the trick:
https://audiokit.io/docs/Classes/AKPanner.html
https://github.com/AudioKit/AudioKit/blob/master/AudioKit/Common/Nodes/Mixing/Panner/AKPanner.swift
let leftPan = AKPanner(metronome)
leftPan.pan = -1
let rightPan = AKPanner(metronome2)
rightPan.pan = 1
let mixer = AKMixer(leftPan, rightPan)
When the player dies, I want the sprite to stop animating on the last frame.
I tried this on Animation End event
if (sprite_index == spr_ninja_dead) {
image_speed = 0;
image_index = image_number - 1;
}
I also tried this
if (sprite_index == spr_ninja_dead) {
image_speed = 0;
image_index = 9;
}
This is the recommended way that GM suggests, yet the sprite freezes on the first sub image. What am I doing wrong?
When the player gets hit, the sprite would change to a flashing sprite image. Then an alarm would change it back to normal. I added an if statement to fix this:
if (sprite_index = spr_ninja_flash){
sprite_index = spr_ninja_idle;
}
What you want to do is run the animation first.
So try this:
if( sprite_index == spr_ninja_dead ){
if( image_index == image_number ){ // This will check if the image is the last image of the sprite
image_speed = 0;
}
}
First you check if the sprite is the dead one, then you check if it's the last image of the sprite and if that is the case you can pause the animation using the image speed.
I am very new to coding and I'm still trying different languages out, I started off with GameMaker Studio and changed to Godot due to its compatibility with Mac I might as well learn something newer since GameMaker has been out for quite some time.
I want to create a RPG game and apply animation to each direction the character moves but the animation only plays after the key is pressed AND lifted. This means that while my key is pressed, the animation stops, and the animation only plays while my character is standing still, which is the complete opposite of what I want. The script looked really straight forward, but doesn't seem to be working.
I would tag this as the GDScript language instead of Python, but I guess I'm not reputable enough to make a new tag, so I tagged it under python because it is the most similar.
#variables
extends KinematicBody2D
const spd = 100
var direction = Vector2()
var anim_player = null
func _ready():
set_fixed_process(true)
anim_player = get_node("move/ani_move")
#movement and sprite change
func _fixed_process(delta):
if (Input.is_action_pressed("ui_left")) :
direction.x = -spd
anim_player.play("ani_player_left")
elif (Input.is_action_pressed("ui_right")):
direction.x = spd
anim_player.play("ani_player_right")
else:
direction.x = 0
if (Input.is_action_pressed("ui_up")) :
direction.y = -spd
anim_player.play("ani_player_up")
elif (Input.is_action_pressed("ui_down")):
direction.y = (spd)
anim_player.play("ani_player_down")
else:
direction.y = 0
if (Input.is_action_pressed("ui_right")) and (Input.is_action_pressed("ui_left")):
direction.x = 0
if (Input.is_action_pressed("ui_up")) and (Input.is_action_pressed("ui_down")) :
direction.y = 0
# move
var motion = direction * delta
move(motion)
As you check the input in _fixed_process, you call anim_player.play() several times a frame, which always seems to restart the animation, and thus, keeps the very first frame of the animation visible all the time.
As soon as you release the key, anim_player.play() stops resetting the animation back to start, and it can actually proceed to play the following frames.
A simple straight-forward solution would be to remember the last animation you played, and only call play() as soon as it changes.
You need to know if the animation has changed
First you need to put these variables in your code:
var currentAnim = ""
var newAnim = ""
And then you add this in your _fixed process:
if newAnim != anim:
anim = newAnim
anim_player.play(newAnim)
To change the animation you use:
newAnim = "new animation here"
I'm fairly new to Polymer and struggling to get some animations to work imperatively. My page displays a grid of cards. When one is clicked, I want the rest to move off screen.
I can get the cards to move one at a time in code, but since they all need to move in parallel, I think I need a core-animation-group to run them. But...
I can't figure out the syntax for creating a core-animation-group in code, and there doesn't seem to be a "play()" method...?
I'd be very, very grateful for a quick example.
TIA
The documentation on core-animation-group is a bit lackluster, but it is possible to create and play a core-animation-group using only JavaScript. Create your core-animation-group with new CoreAnimationGroup(). Then add child animations with animGroup.appendChild(coreAnim). Finally, play the group with animGroup.play().
You say you want to animate an indeterminate number of cards in parallel. Try something like this:
var cards = document.querySelector("#cards-wrapper").children;
var anim = new CoreAnimationGroup();
anim.type = "par"; // Display child animations in parallel.
anim.duration = 200; // Milliseconds
var cardAnimKeyframes = [
// CSS properties {propName: "value"}
{opacity: 1},
{opacity: 0},
];
for (var i = 0; i < cards.length; i++) {
var childAnim = new CoreAnimation();
childAnim.target = cards[i];
childAnim.keyframes = cardAnimKeyframes;
anim.appendChild(childAnim); // This is critical.
}
// Then, when you are ready...
anim.play();
Hope this helps :D
