Is there a way to flip an animation from a programming?

p.robinson

Lets say I have a character, and this character is walking to the right. But now in my game I want my character to walk left so I need to play a walking left animation.

Do I need to
a) go back to Spine and annoyingly mimic the walking right animation so that he now walks left

b) is there some method or neat trick I can call on an animation to simply reverse it.

I prefer option B cause a sounds like a pain in the ass.

Set flipX on the Skeleton to true.

Hmm I seem to be stuck. This project is targeted for iPhones only. It is using the objective-c sprite-kit and Spine. I have the following skeleton

SpineSkeleton *_playerSkeleton;

And I want to change the value of flipX. So I would think you do something like this

_playerSkeleton.flipX = YES;

But flipX is not a property of SpineSkeleton.m , digging through the code flipX/flipY are never mentioned in SpineSkeleton class.
SpineSkeleton is located in my Spine-Sprite Kit folder

However if I go up to the Spine-c source code and navigate to the Skeleton.c class I at last find flipX and flipY being used. But I'm not sure how I would changed the values of either of these since my SpineSkeleton is a SpineSkeleton and not a Skeleton and I don't see SpineSkeleton inheriting from Skeleton.

Thanks for the help!

Where did the runtime come from? There's no official sprite kit runtime.
I suspect a SpineSkeleton has a Skeleton member.

You should keep a reference to that Skeleton if you're going to flip often.

Ah I guess thats my problem, its not an official runtime.

And yes I plan to flip fairly often, when ever the player moves to the left the walking animation is by default animated to go towards the right, so I'd flip there. And then if the player wants to come back I'll have to change the flipX back to false to go to default.

lol. Objective-C is really weird for me to read.

You're right though, SpineSkeleton seems to be the corresponding Skeleton class. But it doesn't have flipX and flipY.

I'm coming from Java so its so weird for me but after a few mini-projects I've gotten used to it and like it a bit more.

Anyway anyone have an idea for a workaround? If not then I'll most likely end up going to Spine and making a WalkingRight animation and a WalkingLeft animation.

I'm kinda confused as to how it's intereacting with spine-c, which classes it's using and which ones it isn't. There should be clues to it where the bones update since that's where flipX and flipY are used but I really... I'm confused. XD

Is this runtime able to do meshes, FFD and skinning?

I only have the Essential license so I never bothered checking if it has the pro features. When I first started I followed this guide to help me get into using Spine.

I really have no clue on how it interacts with spine-c, assuming that it does.
