B4J Question SetLayoutAnimated End using

ElliotHC · Jun 4, 2019

In my game I'm generating images that are falling down the screen.

I'm using SetLayoutAnimated and I'm making (image.visible = false) when I'm finished using it.

Is that all I need to do because things are slowing down after my game has been running a while...

are the images re-used (placed at the top again and dropping) ?

if not you better remove the view.

Yes, I am using the same images but cycling through 1 = 10 im (ImageViews)

Question is, is just hiding them messy?

I need to make sure I'm clearing down anything in my code. Do you know if there is a section on correctly disposing stuff?

sorex · Jun 4, 2019

if you don't create new ones I don't really see why things slow down after a while.

The question is not clear.

ElliotHC · Jun 4, 2019

I think I'm creating new ones each time. I guess once I've created that image and want to take it back up to the start once it's dropped..

Is AddNode creating it again, or just moving it?

My App is racking up some serious memory so something isn't right

B4X:

    im.Initialize("C:/Smash","BACKGROUND_SECTION.png")
            SECTION1.Initialize("SECTION1")
            SECTION1.SetImage(im)
            MainForm.RootPane.AddNode(SECTION1,230,Image_Start_Point - 80,614,254)
            Dim jo As JavaObject = SECTION1 ' the imageview
            Dim o As Object = jo.CreateEvent("javafx.beans.value.ChangeListener","moved",False)
            jo.runmethodJO("layoutYProperty",Null).RunMethod("addListener",Array(o)) ' make sure you choose property that will change
            SECTION1.SetLayoutAnimated(Image_Speed,230,Image_Bottom_End - 80,614,254) ' left/right up/down

If I wanted to create the image but keep re-using it, which part of this code do I use again?

Erel · Jun 4, 2019

1. Load the image once and reuse it.
2. Whenever you call ImageView.Initialize, you create a new view.

Thanks Erel

How do I set the image back to the start position ready for the next animation?

Another animate but with zero duration?

B4X:

SECTION1.SetLayoutAnimated(Image_Speed,230,Image_Bottom_End - 80,614,254)
Sleep(Image_Speed + 10)
SECTION1.SetLayoutAnimated(0, 10, 20, 614, 254)
