[Behavior] LiteTween

powerof2

I just checked and it is working fine, which link is not working?

lunarray

Can you make your LiteTween addon work with expressions?

I'm trying to make an object move from 1 part of the screen to another. Variables don't work because I'm trying to use Positions, which is both X and Y, and I can't include a "," in the variable, or it will screw it up.

Here is a link to my forum post of my problem.

Warning: This is a behavior, not a plugin, so it should go to behavior folder, not plugin folder.

If you need the older v1.5 litetween which is the stable one, this is the place. I added some new feature in 1.7, shouldn't affect much, but just for precaution.

UPDATE

FIX 19/7/2016: Fixing problem with minification and fixing minor typo.

FIX 24/6/2016: Fixing Tween() expression for version 1.7

ADD 17/6/2016: Added parameter changing for easing, back and other stuff.

ADD 17/12/2015: Added LiteTween.Tween(a, b, x, type) function, behaving like lerp(a,b,x)

*: x must be between [0.0, 1.0] or it will clamp it unlike lerp, because tween can't extrapolate value

**: type is the index of tween type, setting it to 0 will use linear tween, 27 would be EaseInOutSmoothstep, etc

FIX 14/7/2015: Re-fixing flip and mirror

FIX 19/6/2015: Three digit version number 1.2.1 changed to 1.3

ADD 18/6/2015: Added State expression and IsReversing Condition

ADD 4/6/2015: Add save/load support

FIX 5/7/2014: Fixed issue of scale tween with flipped or mirrored sprites

CHANGE 29/6/2014: Added new 'force refresh' option when starting tween

ADD 15/5/2014: Added Flip Flop PlayMode

ADD 15/5/2014: Added Scale tweening

FIX 3/3/2014: Fixed issue with EaseInOutBack

FIX 24/1/2014: Fix issue with multiple litetween and value tween on one sprite

FIX 22/1/2014: this.active now store tween active status instead of playmode, and updated on tick to make it more compatible with Tween2Effect

ADD 4/12/2013: Add explanation about position tween in this post, please check below

ADD 4/12/2013: Added Loop play mode

FIX 4/12/2013: Fixed a typo for set target (relative) in height tween

FIX 21/11/2013: Fixed specific bug when angle tween is used with compromise mode

ADD 21/11/2013: Added Horizontal/Vertical tweened property

ADD 21/11/2013: Added Ping Pong

FIX 5/10/2013: Fixed the height tween only accepting x,y parameter

FIX 5/10/2013: Fixed the events firing related to previous bug

FIX 3/10/2013: Fixed the events firing only once bug

FIX 3/10/2013: Fixed the height tween bug

FIX 3/10/2013: Fixed the target property throwing js error

ADD 18/09/2013: Add absolute/relative on property edit

ADD 20/07/2013: Add value tween, value property

FIX 01/07/2013: Resource hog on OnTick

FIX 01/07/2013: Fixed the set parameter bug.

FIX 01/07/2013: Now accept zero duration, it will instantly go to target.

ADD 28/06/2013: Added safeguard against set duration of zero and negative.

FIX 28/06/2013: Removed console.log messages in runtime

FIX 28/06/2013: Added safeguard, ignored set target with NaN value.

FIX 28/06/2013: Small typo fix of "set duration {1}" in edittime

I am going to retire the old EaseTween due to it having complication with bugs after so many feature request. After realizing how hard it is making a simple mouse enter, sprite go big, mouse leave sprite go small, I decided to make this LiteTween plugin.

I will try to keep this one lean, efficient and usable, learning from previous experience of so many feature creeps.

This plugin won't be compatible with EaseTween.

You can also control effect's parameter with LiteTween if you use this behavior by rex_rainbow.

How to use LiteTween

-----------------------------------------

Position, Horizontal dan Vertical tween

In design mode, litetween accepts position in format x, y

Example case 1, you want to tween a sprite from current position to the coordinate 200,100

How to do that in the design view (not on event sheet):

a. Set Target to 200,100.

b. Set Target Mode to Absolute

c. Make sure Active on Start is 'Yes'

Example case 2, you want to move a sprite to left by 100 pixel using the design view

a. Set Target to -100, 0

b. Set Target Mode to Relative

c. Make sure Active on Start is 'Yes'

Note: Or you can just use Horizontal tween

Example case 3, you want to move a sprite to left by 100 pixel, whenever your user click the sprite (on the event sheet)

a. Create an on touch sprite condition

b. Make a litetween action Set Target X (relative), value -100

c. Make a litetween action Set Target Y (relative), value 0

d. Start the tween "from the beginning"

Note: Or you can just use Horizontal tween

Warning: Set X and Set Y action is an inseparable pair on position tween.

If you do a Set X action, don't forget to do a Set Y action too. Many people think it is a bug, where it is actually not . A Set X action without a set Y action will use previous Y, even in relative mode, causing all kind of unexpected problem...

Note: The same apply with Set Y without a Set X.

Angle tween

Angle accepts value in degrees. That is to rotate three times clockwise, just enter 1080 in value. To rotate three times counter-clockwise, enter -1080 in value.

Opacity tween

Opacity accepts value from 0 (fully transparent) to 100 (fully opaque).

You can actually set it beyond 100.

Value tween

Value accepts any float number as target.

1. Set starting value using 'Set Value' action.

2. Set target value using 'Set Target' action.

3. Start the tween.

4. To check the current value use the Value expression.

Size tween

Size tween accepts target size in pixel in format width,height as target.

Width tween accepts target size in pixel.

Height tween accepts target size in pixel.

Hello I have a problem about plugin

when I exported my project to HTML5. I found "lunarray litetween" didn't work on Chrome browser and others Why? and How should I do. Please help.

Thank you

lunarray - Wow. I did not know I need this behavior until now... I use lerp/dt but found out it's not smooth. lunarray - Can I ask why this plugin is smoother than lerp/dt?

Thanks.

krisnk

I tested on chrome browser and it worked fine, can you be more specific about the steps to reproduce the problem? And also, this is a wild guess but it is a behaviour, not a plugin, so you should put it into behavior folder, not plugin folder, maybe that is why?

UltimateArceus3

It does work with expression to some extent; Though you need to know how to convert numerics into strings and vice versa.

I don't really understand the problem you encounter, are you using Set Target X and Set Target Y? Or are you using create/initialize tween? Sometimes using Set Target X and Set Target Y would be more convenient, depending on the case. I could help more if you could provide me with a simple capx describing what you want.

I am not sure either. If it is on the weaker device with less processing power, it might be because LiteTween is using precalculated array instead of having to calculate the lerp every tick, so it is lighter on the CPU. But if it is on an adequate PC/mobile, lerp/dt should have about the same smoothness with linear LiteTween.

Thanks! That fixed it up!

I'm making a "simple" card flip. With this. (on touch flip this card type of thing) ... experiencing a weird behavior when someone clicks multiple times the card (multi clickers) it doesn't perform as expected. Hopefully I'll manage to clean it up. this is my test

lunarray I think EaseInBack is not working properly, it behaves the same as EaseOutBack

Cipriux

Thank you for noticing that bug, that's a simple typo, I just fixed it. The download link is on the first page like usual. Please tell me if it is still not working correctly.

Ragevortex

You should use Enforce mode > Enforce. Don't use compromise for this case.

lunarray That fixed, thanks

lunarray I really love your behavior, I use it in almost all my games for the last past year, but I want to move an object from X1,Y1 to X2,Y2 using a curved line instead of straight line. I tried putting 2 behaviors on the same object but I could not manage to make them work together.

Please have a look at this image. The image represents the object actual movement on XY plane (not a easing curve) .Do you think it can be done?

Thanks in advance

Cipriux

Sure it can do that. My wild guess for that problem is that you use Enforce instead of Compromise. Because of that, one of the tween won the enforced coordinate for the other. If you want the second graph which looked like a circleEaseOut to me, you need to tween linearly for X (Horizontal tween), and tween easeOutCircle for the Y (Vertical tween).

I made a simple capx, I hope this is what you need.

lunarray Thanks .That looks great !!!

Quick question... perhaps I'm just tired.

When attempting your tween to a sprite that's mirrored using your 'apple' demonstration, it seems to revert back to a non-mirrored state during transition... perhaps I'm doing something wrong. I have your latest plugin (1.7) so i was wondering if there was something I can do to fix that?

Here's an example:

https://1drv.ms/u/s!AtM48QkzXUgxsjlQZ464P5dkxT76

Am I doing something wrong? You'll see what I mean when you try. I created two different sizes so you can compare - it shouldn't matter the size, it should always work as intended with the code provided.

Can i use this LiteTween v.1.7 version for current updated version of C2 or there is new updated LiteTween version available ???
