Runtime information
Tell us your Spine Runtimes version.
Runtime 4.2
Hi! I've been using the Spine2D generic cpp runtime with raylib, a c++ game development framework.
I can get things to render fine, but there is a problem with the scale option.
What I Tried
I tried rendering the default spine boy project included with Spine.
Here is the setup code I used: (I left out the raylib-specific render code)
atlas = std::make_unique<spine::Atlas>(util::getAssetPath("spine/spineboy-pro.atlas").c_str(), &textureLoaderSpine);
skeletonJson = std::make_unique<spine::SkeletonJson>(atlas.get());
skeletonJson->setScale(1);
skeletonData = std::unique_ptr<spine::SkeletonData>(skeletonJson->readSkeletonDataFile(util::getAssetPath("spine/spineboy-pro.json").c_str()));
// Create the spAnimationStateData
animationStateData = std::unique_ptr<spine::AnimationStateData>(new spine::AnimationStateData(skeletonData.get()));
// Set the default mix time between any pair of animations in seconds.
animationStateData->setDefaultMix(0.1f);
skeleton = std::unique_ptr<spine::Skeleton>(new spine::Skeleton(skeletonData.get()));
skeleton->setX(400);
skeleton->setY(400);
skeleton->setScaleX(0.5);
skeleton->setScaleY(0.5);
What I Expected
I expected the sprite to render exactly as it should, facing the right side and displaying a walking animation.
What I Got
When I set the scaleX to positive and the scaleY to positive, nothing renders at all.
skeleton->setScaleX(0.5);
skeleton->setScaleY(0.5);
But when I set either the scaleX or scaleY to negative, the animation renders just fine (I'm using the example animation from the spine boy project included with Spine).
skeleton->setScaleX(-0.5);
skeleton->setScaleY(0.5);
GIF example (x flipped, renders properly)
