Is it possible to detect a hitTestPoint on a movieclip item?

mykyl66

On single image items doing this :-
function onMouseDown(self, event)
print ("yep, you touched me")
if self:hitTestPoint(event.x, event.y) then
self.isFocus = true
self.x0 = event.x
self.y0 = event.y

etc etc etc works perfectly. I can get and print out x, y positions and anything I like.

However on an item that is made up using a movieclip
the same function would be triggered but only the print statement would actually do anything. Anything after the print statement doesn't trigger at all.

If you need any more info then please ask.

Currently I am guessing a hitTestPoint doesn't register with movieclips.

You're right and this bug is fixed. And I cannot offer a temporary solution.

Well hitTestPoint is Sprite class function, and MovieClip inherits Sprite, so it should work.

On the other hand, Movieclip is a collection of multiple frames, each one could be in different sizes. Which can make it complicate to test point.

Do you use movieclip for animation looping, or simply changing images as different states of object?

How about creating invisible sprite above it and testpoint that?

atilim

The problem with current implementation (beta8) is getWidth() and getHeight() functions return 0 for MovieClip. Therefore hitTestPoint doesn't work correctly.

That's a real pain as this would have been a quick game to develop and get out the door. It can still be done but would look boring with static items.

Back to the drawing board.

Not a very good solution but you can add a invisible child to the MovieClip approximately with the same size. So that its bounds will be valid and hitTestPoint will work correctly. :-\"

Well my quick idea was to use same image or image with same dimensions as in movie clip in a bitmap, make bitmap invisible, place it in same position as movieclip, and add it to stage after movie clip, so it would be positioned on it.
Thus, you have your movieclip animation, and transparent layer above it (invisible sprites still receive click events, don't they?)

I'm always late with my response, somehow atilim is always first. Not mentioning his solutions are also better

atilim

ar2rsawseen solution also works. yes, invisible sprites still receive mouse/touch events.

mykyl66

Yup would likely work. Will develop it as a non animated game for now and put it to the side for when the issue is solved unless of course the game works as well as I think it should from playing a real world version on my kitchen floor. Then it will have to be done in any way I can.

LOL :-))

ar2rsawseen

Wait what? you can still use animations, don't mind hacks, they're good for you

atilim

totally agree >-

mykyl66

lol. Your right.
In fact, I am usually the one that says "if it works right, it is right". Never thought I would have that from others.
