I have two Sprites, where one is layer 3 and the other layer 4. For some reason the lower vertical half of the layer 4 Sprite hides behind the layer 3 Sprite. As images show.
This is my QC composition:
Does anyone have any idea of why this is happening?
It could be a result of depth testing being on. If you don't want the position of the Sprite to determine the on screen visibility try setting Depth Testing to None on your Sprites.

I have a number of square regions in my game screen which, when actors move across these regions, I want the background image to show through from behind.
So, is it possible to draw to a SpriteBatch such that a region is subtracted/deleted from the texture (effectively "punching a hole" in it)?
I can't think how else to achieve this... Scissors seem incredibly impractical for my purpose, as I want to clip the areas INSIDE a number of squares. This is the inverse of Scissors - which clip areas OUTSIDE the scissors' bounds. The thought of calculating dozens of Scissor regions to fill the inverse areas between an assortment of square regions seems too impractical to be the solution... especially if the regions are moving.
Any help or suggestions appreciated!
UPDATE: Image attached.
I want the background to always be visible in the areas marked with the dotted lines. The dotted areas will move, so I'd rather not create more sprites from the background to lay on top, but rather have parts of the actors intersecting the dotted squares not be drawn. (Or any method that will achieve the same effect.)
I think the best hack is to not try and be so precise about clipping your actors, but to just re-draw the background on top the actors (and to clip that).
Specifically:
draw the whole background
draw your actors/sprites
draw the background with one cliprect for one part that "shows through"
draw the background with another cliprect for the other part that "shows through"
draw the dotted boxes around your cliprect areas
Great image, by the way. Easily worth 1000 words. :)
I am trying to get an effect like this:
http://www.welcomeanimations.com/welcome_animated_gifs_rotating_sign_orange_chrome_k_1.htm
I have tried all sorts of things:
Matrix translation/rotation - spins the text around the 'Z' axis, instead of 'Y'
Adding TextField to a sprite, and Sprite.rotationY++: reg. point is upper left corner
Adding to MovieClip - same as above (an article said MovieClip's reg. point was centered).
This should be trivial?!?! Help me stackoverflow, you're my only hope!
So you have to remember, Display objects scale and rotate around their local coordinate system. so when you put a textfield in a sprite, you need to center it in that sprite's coordinate system. And doing that for textfields is annoying because their width/height isn't always accurate but there is trick for that: get visual bounds, but normally you can take half of somethings width and height
I've created a prototype for you on wonderfl so you can see the solution working in action. Click on the blue square to see how the local coordinate system messes with the rotation
Finally as you use thing you might find things not rotating in 3D space quite right, this should be able to fix that.
I have this background that I'm using for a section, and it starts with a small arrow engraving at the top:
However I'm trying to get it when it repeats to clip out the top arrow part, just leaving the texture in the middle part. I was wondering if it was possible to do it with something like webkit? Thanks
You can't. You need to come up with another method of doing so. There are a number of ways to do this. Personally, I would use only the arrow, but use inner box-shadow for the shadows on everything else. This way you have smaller image being used, and it will always fit the size of the container.
Break up the background image from the pointer and make the two separate sprites. You can get tricky with the pointer and have it point in all 4 directions in the same image. This will allow you to pop up the bubble in all directions from the source.
You can't repeat both x and y on a usable sprite.
I have a maximum of three sprites in my projects.
One for non-repeating elements, another for repeat-x, another for repeat-y.
I find the clip property pretty much useless.
I have two images, a gameboard and the same gameboard with all posible player positions in a pressed state. When a player moves to a position on the board, I put the board image over the pressed board image and slice using context.drawImage() on the pressed image, to display the pressed position through the slice. However, my game board contains positions which are not rectangular but different shapes.
Is it possible with html 5 canvas, to cut a non-rectangular shape out of an image to display the underlying image?
I found it's possible to use clip() on shapes but I can't find a similar option on images.
you can create a third image that is a mask with transparent (alpha-channel) pixels and non-transparent pixels, and use a
globalCompositeOperation
to merge the mask and the to-be-masked image into a new image ( think you can use an xor or source-out here..
I have a movieclip with the mesurements of a rectangle. When the application is launched the movieclip is being scaled before placed on the stage as following.
menu.width = 400;
menu.scaleY = menu.scaleX;
this is a smaller size than the original.
the position of the movieclip at this moment is in the middle on the x and top of the stage on the y.
when i click iti would like to do a tween with tweenlite wich scales it to its original(bigger) width and height and position it in the center of the stage on x and y.
the problem is when i position it with tweenlite, it gets done according to its old scale and not according to its new(bigger) scale so the movieclip isnt placed in the exact center of the stage.
Anyone know how i can resolve this?
I tried to compensate by adding a bigger number on the position so it gets positioned in the right way.
But when i click it again i would like it to rescale to its beginning scale and position so it would be very messy to compensate again. Is there any easier way to do this kind of tween?
I doubt that i'm being clear to what i want but i hope i am after all.
The easy and way of tween position and scale is probably to add the menu to a container.
You would then on one hand tween the position of the container, and on the other apply the scale to the menu it self without having to recalculate the proportional position if the scale changes.
This way you can even control the registration point of the menu within the container. e.g. to always scale from the middle...
This can be done with a matrix as well if you want to avoid to stack objects, but honestly it can get really tricky whereas the container method is bullet-proof.
