How to ignore touch on ui::slider progressbar and only on thumb?

[paulocoutinhox]

Hi,

How to ignore touch on ui::slider progressbar and only on thumb?

My code:

auto rotationSlider = ui::Slider::create();
rotationSlider->loadBarTexture("cocosui/sliderTrack.png");
rotationSlider->loadSlidBallTextures("cocosui/sliderballnormal.png", "cocosui/sliderballnormal.png", "cocosui/sliderballnormal.png");
rotationSlider->loadProgressBarTexture("cocosui/sliderProgress.png");
rotationSlider->setPercent(characterEntity->rotation / 360 * 100);
rotationSlider->addEventListener([rotationSlider, characterEntity](Object*, ui::Slider::EventType type) {
    if (type == ui::Slider::EventType::ON_PERCENTAGE_CHANGED)
    {
        float newRotation = rotationSlider->getPercent() / 100.0f * 360;
        characterEntity->rotation = newRotation;
        characterEntity->applyChanges();
    }
});
addLabelAndComponent("Rotação", rotationSlider);

Thanks.

Sub-class ui::Slider, and override the Slider::hitTest method. Changing the implementation to something like this should work:

bool YourSlider::hitTest(const ax::Vec2& pt, const Camera* camera, Vec3* /*p*/) const
{
    Rect rect;
    rect.size = _slidBallNormalRenderer->getContentSize();
    auto w2l  = _slidBallNormalRenderer->getWorldToNodeTransform();

    return isScreenPointInRect(pt, camera, w2l, rect, nullptr);
}
