I'm using cocos2d-x 3.17. When I run a Follow action on a sprite, the tiled map can't render fully. The map looks exactly the same as the screen record shows in posts below
https://discuss.cocos2d-x.org/t/1-5b2-tiled-map-not-rendered-fully/36661
https://discuss.cocos2d-x.org/t/solved-tilemap-rotation-clipping/37114
But they were using Cocos Creator and can fix it by setting ENABLE_TILEDMAP_CULLING = false.
Is there any equivalent settings in C++ api?
Found out the root cause is that the Scene has been moved by Follow action. It seems in cocos2d-x, Scene is not supposed to move.

I have few questions here, regarding creating app in Adobe Air using Starling and feathers.
I created yet a very simple app, which has Feathers list controller with static data provided to its dataProvider. According to the code it should work fine, but there are three major issues I am facing.
1: Touch/Click Positions
I am using:
list.addEventListener( Event.CHANGE, list_changeHandler );
Now the problem is, clicking coordinates are not correct. Clicking on 3rd Item triggered 4th item, to trigger 3rd, 2nd item needs to be clicked it's half way through etc.
2: Nothing, without Theme
I am using a custom theme, came along with a tutorial. If I don't use the theme, I am unable to see anything on the screen, somehow.
3: Resolution (Device Simulator) Problem
Though buggy, but it works with Theme, but my app doesn't fit with the resolution for each device simulator. Either its, iPad or iPhone 4 or any android simulator.
Also, can anyone please also explains, what is significance and use of Context3D render mode in starling class.
Any help is appreciated:
Thanks in advance

Starling is a Stage3D framework that displays content directly on graphic card using Context3D. Everything displayed by Starling is always under the regular display list. Feather is a component framework based on Starling.
Stage3D cannot handle any mouse operations so Starling and Feather simulate all their mouse event (those mouse event never really happen anywhere, they are created by calculation of mouse position on the stage)
not sure, never used Feather
Starling does not handle screen density and dpi calculation, if you want your app to fit any screen you'll have to handle it yourself.
I think you should see the example carefully. if u want to use any feathers component either you have to use feathers theme or custom theme.
if you use feather theme you need to provide theme path and before using any component you need to initialize that theme.Then use component any where.without theme you will not see any thing.
1: Touch/Click Positions
please provide minTouchHeight in class theme of DefaultListItemRenderer like:-
renderer.minWidth = this.gridSize;
renderer.minHeight = this.gridSize;
renderer.minTouchWidth = this.gridSize;
renderer.minTouchHeight = this.gridSize;
2: Nothing, without Theme,
3: Resolution (Device Simulator) Problem
Follow the example given in feather library
feathers-2.1.1\themes\MetalWorksMobileTheme\source\feathers\themes
I'm loading in an external image (a book cover from goodreads.com) into a library viewer AIR app (used on ipad and in-browser) running on Starling (in case you need to know). After it loads, the cover should be clickable to take further action.
This all works fine on ipad and when directly built from FlashDevelop, but when it's viewed in-browser, click events don't do anything on the loaded images. It'll work on my embedded placeholder bitmaps no problem (sitting in a "Book" class extending Sprite).
It seems to be a security problem, but if it was, I'd expect the image to not load at all. But instead it loads but isn't interactive anymore. I've tried various things like:
Add loader and click listener to the Book object
Add loader.content as Bitmap and click listener to the Book
Create a BitmapData and draw the Loader.content, then add the resulting Bitmap (it's blank in-browser, but works perfectly when built from FD)
Add loader and place a transparent sprite on top of it, add listener to the sprite
Has anyone had this problem? Would anyone know a work-around?
Thanks!
This was a sand-box problem.
I think it's intentional; you shouldn't be able to hot-link other site's assets unless given express permission.
I fixed this by only pulling images hosted locally and using crossdomain.xml to make sure there was no lookup issues when www.domain.com and domain.com were different.
In 1.1, the GMSScreenshot class provided a rudimentary way to get a snapshot of the entire screen into a UIImage. In 1.2, the class is missing, and in the release notes, it says this:
Calling renderInContext: on the GMSMapView layer now renders correctly;
this allows for snapshots and UI effects
Unfortunately, I'm not finding this to be the case. Typically renderInContext: does not work on Open GL drawing, but I figured I'd take a shot anyway (it didn't work). Has anyone been successful in getting a (preferred) view or screen snapshot?
I am able to take a screenshot. Here is the code I use:
UIGraphicsBeginImageContext(mapView_.frame.size);
[mapView_.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *screenShotImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
I do not call this straight after I create the map as it can take some frames for the map to render.
I'm failrly new to LibGDX and I'm running into a problem.
I'm building a classically styled RPG/Adventure game in which I'm using a TiledMap(-Renderer) to create the map. I've followed different tutorials but can't get it to work. (last one was DPG's: Full working example link)
What I need, is a column of buttons on the right side of the screen (implemented that through ImageButtons). One of these buttons lead to a settings-kind of screen and another one should lead to the game map. Under a ClickListener of the button I've added DPK's code of
MapHelper map = new MapHelper();
map.setPackerDirectory("data/packer");
map.loadMap("data/world/level1/level.tmx");
map.prepareCamera((int)stage.getWidth(), (int)stage.getHeight());
map.getCamera().update();
map.render();
The MapHelper class is an exact copy of dpk's, only change above is the setting of the width and height of the camera. Any suggestion what I'm doing wrong here?
I don't think you want to invoke map.render() in the ClickListener callback. That would mean the map is only rendered when you click, and then not re-rendered (generally everything gets re-rendered on every screen re-fresh).
I think you need to track the map in your application class, and in the ClickListener callback you need to set a flag or somehow "enable" the map (perhaps setting it to something other than null). Then in the application's render() method you can check to see if the map should be rendered or not, and render it if so.
Specifically, move the calls to prepareCamera, getCamera and render out of the ClickListener.
Today I wanted to add mouse-driven zoom and pan functionality to a pure AS3 project - something like the Google Maps interface. I was surprised that I couldn't find a good package or library to do this already - I'm using FlashDevelop rather than Flash CS3, so the nice VCam tool available as an FLA is no use.
There's nothing very complicated involved in implementing zoom/pan, although it can be fiddly and time-consuming to get right, but since zooming and panning are pretty common things to want to do I wondered if anyone could suggest a 'correct' way to do this in the Flash world, or a good library available that I haven't been able to find.
I found exactly what I was looking for in the flare library's PanZoomControl:
Interactive control for panning and
zooming a "camera". Any sprite can be
treated as a camera onto its drawing
content and display list children. To pan and zoom
over a collection of objects, simply
add a PanZoomControl for the sprite
holding the collection.
var s:Sprite; // a sprite holding a collection of items
new PanZoomControl().attach(s); // attach pan and zoom controls to the sprite
The mouse controls are also implemented as you'd expect:
Once a PanZoomControl has been
created, panning is performed by
clicking and dragging. Zooming is
performed either by scrolling the
mouse wheel or by clicking and
dragging vertically while the control
key is pressed.
You could use a 3D library such as Papervision3D or FIVe3D. Then just move your camera based on different mouse events/gestures. Or use the built in z-axis in FlashPlayer 10 to get the zoom effect.
