Hi,

I have a problem with deleteobject command. When I remove all my 3d objects of my scene... 200 objects in Android, sometimes, the application is closed (crashed)... the code is inside a function... the important loop is:

+ Code Snippet

for i=1 to 200
deleteobject(i)
next i

however, if you use this code:

+ Code Snippet

for i=1 to 200
deleteobject(i)
sync() //the only difference
next i

the app works fine.

Do you know why?

Thanks!

Sounds like a bug to me. Can you write a simple example that can be run easily and post it on the bug board?

this.mess = abs(sin(times#))

Ok, I know what is the problem... delete objects with transparency! But this can be a problem of my device... i don't know... and i can't post it on the bug board if I am not sure...

This code is not working for me (using AppGameKit player in Asus tf300)

+ Code Snippet

img=loadimage("img.png")

for i=1 to 200
    createobjectsphere(i,1,10,10)
    setobjectimage(i,img,0)
    setobjecttransparency(i,1)
next i

do
    if getpointerpressed()
        for i=1 to 200
            //setobjecttransparency(i,0)
            deleteobject(i)
        next i
    endif
    sync()
loop

If you uncomment the line setobjecttransparency(i,0)... the app is not closed.

Can you test it in your Android device?

Thanks!

Try this (make sure a double press isn't detected):

+ Code Snippet

img=loadimage("img.png")

for i=1 to 200
    createobjectsphere(i,1,10,10)
    setobjectimage(i,img,0)
    setobjecttransparency(i,1)
next i

do
    if getpointerpressed()
        for i=1 to 200
            if getobjectexists(i)
              setobjecttransparency(i,0)
              deleteobject(i)
            endif
        next i
    endif
    sync()
loop

EDIT: Does your app work in Windows properly?

Ancient Lady, The app works in windows... the problem is android.

I think that I have not explain it very well (and my english is bad).
If you use setobjecttransparency(i,0), the application works fine, but if you don't write this line the app is closed (although you use getobjectexists(i)). The trick is setobjecttransparency(i,0).

Thanks

EDIT: At least, in my device

I am assuming you are using AppGameKit v1088, correct?

Where did you get your player from?

What Android device are you using and what version of Android is it?

If you post the image file you are using, I will try your code on my devices.

Hi and Thanks Ancient Lady!

I am using AppGameKit 1088. I have used two AppGameKit players: I built one player and I downloaded the player from forum

I have used Android 4.1 and 2.3.5. The devices: Sony Ericson xperia neo V, samsung galaxy mini and Asus TF300

I have used a lot of images... but in this example, I am using AppGameKit image (attachment).

I have discovered that if you use setobjecttransparency(obj,1 (or 2)) command, you will have problems... even if then, you use setobjecttransparency(obj,0)

With this example, you can test the problem... repeatedly touch and the app will be closed.

+ Code Snippet

SetDisplayAspect( 4.0/3.0 )

img=loadimage("img.png")

for i=1 to 200
    createobjectsphere(i,1,10,10)
    setobjectimage(i,img,0)
    setobjecttransparency(i,1)
next i

do
    if getpointerpressed()
        if getobjectexists(1)
            for i=1 to 200
                setobjecttransparency(i,0)
                deleteobject(i)
            next i
        else
            for i=1 to 200
                createobjectsphere(i,1,10,10)
                setobjectimage(i,img,0)
                setobjecttransparency(i,1)
            next i
        endif
    endif

    sync()
loop

Thanks!

Hi again,

I have tried new things... The problem is removed if you use render3d()... I don't know why...

my new code is:

+ Code Snippet

SetDisplayAspect( 4.0/3.0 )

img=loadimage("img.png")

for i=1 to 200
    createobjectsphere(i,1,10,10)
    setobjectimage(i,img,0)
    setobjecttransparency(i,1)
    setobjectcolor(i,255,255,255,100)
    setobjectposition(i,random(0,20)-10,random(0,20)-10,0)
next i

do
    if getpointerpressed()
        if getobjectexists(1)
            for i=1 to 200
                deleteobject(i)
                render3d() //THIS LINE REMOVES THE PROBLEMS
            next i
        else
            for i=1 to 50
                createobjectsphere(i,1,10,10)
                setobjectimage(i,img,0)
                setobjecttransparency(i,1)
                setobjectcolor(i,255,255,255,100)
                setobjectposition(i,random(0,20)-10,random(0,20)-10,0)
            next i
        endif
    endif

    sync()
loop

greetings!

Tgc made some changes in the syncing that could be the problem ?
I noticed that the speed of agk apps decreased alot after adding 3d commands and they made some changes to speed things up again .

Android 2.3 , ZTE Skate , 480x800 , 800 mhz , Samsung Galaxy Y , 240x320 , 832 mhz , Sony ericson arc 480x854 , 1 ghz
Android 4.0 , Dmtech 3g 9738B , 1024x768 , 9.7 inches , 1.2 ghz

Well, I was testing, to see where the issue might be coming up.

This is the final test code (including your fix):

+ Code Snippet

SetVirtualResolution( 600, 480 )

global img as integer
global scnt as integer
scnt = 200
img=loadimage("img.png")
make_spheres()

do
	if getpointerpressed()
		if getobjectexists(1)
			delete_spheres()
		else
			make_spheres()
		endif
	endif

	sync()
loop
end

function make_spheres()
	for i=1 to scnt
		createobjectsphere(i,1,10,10)
		setobjectimage(i,img,0)
		setobjecttransparency(i,1)
		setobjectcolor(i,random(120,255),random(120,255),random(120,255),random(120,255))
		atx# = 1.0*randomsign(random(1,10))
		aty# = 1.0*randomsign(random(1,4))
		atz# = 1.0*randomsign(random(1,3))
		setobjectposition(i,atx#,aty#,atz#)
	next i
endfunction

function delete_spheres()
	for i=1 to scnt
		setobjecttransparency(i,0)
		deleteobject(i)
		render3d()
	next i
endfunction

When I had scnt at 20 and without the render3d(), I could execute from my PC and repeat to my hearts content.

When broadcast to the Android Player, I could get about about 27 clicks and the next would crash it.

When broadcast to an iOS Player, it crashed on the first click.

If I set scnt to 200, the Windows version crashed on the first click. I didn't bother trying on the Players.

When I added the render3d() command in, everyone was happy.

So, it is the rendering/syncing that is killing us.

This sounds like a new issue.

Go ahead and post, use my code example in the post and attach the image (for completeness).

I'll then officially confirm it as a bug.

MikeMax, where are you doing the render3d()?

I tried doing it after the loop that did the deletes, but it didn't fix it. It had to be right after the delete command.

+ Code Snippet

function DeleteObjLoaded()
  for i=1 to GlobalCountObjLoaded
    if GetObjectExists(OBJLoadedID[i])
      DeleteObject(OBJLoadedID[i])
      Render3D()
    endif
  next
endfunction

i've tried it just after each deleteObject command .... but i have a lot of objects in each race tracks (i will count them exactly but between 200 and 300 ) ...

i've sent my entire source code to Rick and Paul. They will try to reproduce it (but they already use the next beta version and it seems that the problem has disappeared ...).

I'm waiting for a response soon
