Player not centered - STLayerPanZoom and STCameraManager

[paulocoutinhox]

Hi guys.

Can someone help me with a problem? I made a video to show. Im using STCameraManager and STLayerPanZoom to make the camera follow the player. It is following, but have something that make the camera no centralized, but more to left and the player more to right.

Can someone help me?

My code:

void BasePlatformStageScene::setupCustom() {
    // setupPanZoomLayer is now called in setupLayers override
}

void BasePlatformStageScene::setupLayers() {
    // setup pan zoom layer first
    setupPanZoomLayer();

    // then call base implementation which will use our addChildLayer override
    BaseStageScene::setupLayers();
}

void BasePlatformStageScene::enablePlayerFollow(ax::Node *player) {
    if (panZoomLayer && player) {
        followTarget = player;
        // schedule update to handle custom camera following with offset
        schedule([this](float dt) {
            updateCameraFollow(dt);
        },
                 "CameraFollowUpdate");
    }
}

void BasePlatformStageScene::disablePlayerFollow() {
    followTarget = nullptr;
    unschedule("CameraFollowUpdate");

    if (panZoomLayer) {
        panZoomLayer->stopAllActions();
    }
}

void BasePlatformStageScene::setupPanZoomLayer() {
    // create pan zoom layer
    panZoomLayer = STLayerPanZoom::create();
    panZoomLayer->setPosition(Vec2::ZERO);
    panZoomLayer->setAnchorPoint(Vec2::ZERO);
    panZoomLayer->setupInput();

    // disable zoom functionality (only want pan/follow)
    // panZoomLayer->setZoomDisabled(true);
    panZoomLayer->setMinScale(0.1f);
    panZoomLayer->setMaxScale(4.0f);

    // add pan zoom layer to scene (between background and UI)
    addChild(panZoomLayer, 1);

    // setup camera manager
    STCameraManager::get()->setupWithPanZoomLayer(panZoomLayer);

    // setup camera offset (player positioned lower on screen for better visibility)
    auto visibleSize = _director->getWinSize();
    cameraOffset = normalOffset; // use the normal offset as default
}

void BasePlatformStageScene::updateCameraFollow(float dt) {
    if (!followTarget || !panZoomLayer) {
        return;
    }

    // position absolute (world space) of the player
    const Vec2 playerAbs = followTarget->convertToWorldSpaceAR(Vec2::ZERO);

    // convert to the space of the panZoomLayer (node space that the camera uses)
    const Vec2 playerInPanZoom = panZoomLayer->convertToNodeSpaceAR(playerAbs);

    // dynamic zoom/offset
    if (auto platformCharacter = dynamic_cast<game::character::BasePlatformCharacter *>(followTarget)) {
        const float targetZoom = platformCharacter->isJumping() ? jumpZoom : normalZoom;
        currentZoom += (targetZoom - currentZoom) * zoomSpeed * dt;

        const Vec2 targetOffset = platformCharacter->isJumping() ? jumpOffset : normalOffset;
        const float a = std::min(1.f, offsetSpeed * dt);
        currentOffset = currentOffset.lerp(targetOffset, a);

        // apply the zoom to the layer that the camera manages
        panZoomLayer->setScale(currentZoom);
    } else {
        currentOffset = normalOffset;
        currentZoom = normalZoom;
        panZoomLayer->setScale(currentZoom);
    }

    // desired center in the same space as the panZoomLayer
    const Vec2 desiredCenter = playerInPanZoom - currentOffset;

    // move the camera
    STCameraManager::get()->setViewpointCenter(desiredCenter, false);
}

Solved. The problem is character anchor point, need be setAnchorPoint({0.5f, 0.5f});.
