but after delete all sprite and redo
fond =createsprite(2)
<some others line code>
player[0]=create sprite(3)

player[0] delete the fond sprite because both have 10001 value

if i want it work i need to pute these 2 line very near.iI have try to change myself the value doing fond=245878 , if before create sprite, create sprite change the value again for 10001 .If i do it after its weird, others sprite created before dont appear more.

Hmm is it possible your running the same line twice after the first instance... Hard to say without the " some other code" lol

I dont think, i have understand a sprite id is a number after 10000 given automaticly by the app, and they must all have different nomber (for dont be the same) , then when i create player[id] it give the same number to player[id] as fond . 10001 for both . I check later again.
THank!

Do you have an example project which shows your problem?

I can create multiple sprites then delete them all with DeleteAllSprites() then create them again and the sprite numbering does start at 100001 and they each have a unique id Ie 100001, 100002, 100003 etc... They dont just stay at 100001.

Are you sure it isnt just a bug in your code?

I don't know what else is involved without more code from the OP, but if using 2d physics, dont forget that the walls are sprites, as well.

You could try printing getspriteexist and see if it's actually deleting it while running the code maybe ?

You need to pass zero to the function, then the agc will assign the desired id to the sprite.

+ Code Snippet

sprite = createprite (0)

//or

array_sprite as integer []
for i = 0 to 8
  array_sprite.insert(CreateSprite(0))
next i

//or

array_sprite as integer [8]
for i = 0 to 8
  array_sprite[i]=CreateSprite(0)
next i

//========================================
image = LoadImage("image.png")
sprite=CreateSprite(image)

//delete
if GetImageExists(image) = 1 then DeleteImage(image)
if GetSpriteExists(sprite) = 1 then DeleteSprite(sprite)

//or 

sprite=LoadSprite("image.png")
//delete
//When deleting a sprite that was created using this command -"LoadSprite", the image will be deleted automatically.
if GetSpriteExists(sprite) = 1 then DeleteSprite(sprite)

//========================================
//If you want to use the same image for multiple sprites, 
//you only need to feed the image once and make sprites from it so that you do not load the same image in a loop.

image = LoadImage("image.png")

array_sprite as integer [8]
for i = 0 to 8
  array_sprite[i]=CreateSprite(image)
next i

That's not correct, only pass 0 to the sprite if you want a blank white image applied to it.

He was using CreateSprite(2) and createsprite(3) indicating that he had previously loaded images LoadImage(2,"Image.png") , LoadImage(3,"Image2.png")

If those images didnt exist he would get an error stating that image 2 doesnt exist and then sprite id returned is then 0....not 100001

@Bengismo, you are right, but by my example I wanted to show something else, that you can refuse numbers and use variables. And as noted above, without a code that reproduces the error, these assumptions are all meaningless.

"DeleteSprite()" deletes the sprite correctly, it just does not reset the internal sprite counter.

+ Code Snippet

SetClearColor(40,150,250)
//--------------------------------------------------------------
LoadImage(1, "img.png")
spr1=CreateSprite(1)

LoadImage(2, "img.png")
spr2=CreateSprite(2) : SetSpriteX(spr2, 100)

click_step=0
do
	print("id1: " +str(spr1))
	print("id2: " +str(spr2))
	
	if GetPointerPressed()=1
		select click_step
			case 0:
				DeleteSprite(spr1)	
				DeleteSprite(spr2)	
				inc click_step
			endcase
			case 1:
				spr1=CreateSprite(1)
				spr2=CreateSprite(2) : SetSpriteX(spr2, 100)
				click_step = 0
			endcase
		endselect 
	endif

    Sync()
loop

Everything is working correctly. I assume that he has an error in the code.

Absolutely understand. I normally use the auto generated ID's and only rarely use static id numbers for any resource. I would recommend allowing AppGameKit to manage ID's, buts thats my preference. Either way works fine though. Its much more likely to be a small error in user code somewhere.

DeleteAllSprites() does start the id's at 100001 again and you are right that DeleteSprite() doesnt reset the counter and it shouldn't do so. If he is getting 100001 after recreating sprites then its likely he used the DeleteAllSprites() function to delete them all.

Quote: "without a code that reproduces the error, these assumptions are all meaningless."

This is the main point, well said. There are good ways to ask questions and bad ways which dont give a lot of information that cant be answered.

We can only use the information that was given by the original post which isnt really enough to answer the question.

Hi all, thank so much for your answer, yes i use deleteallsprite, when the level of the game is finish, win or not, i use deleteallsprite.
I have do a try for find when i have same ID value. and here:

test=getspriteexists(cadreperso[0])
collisiongauche[1]=clonesprite(collisiondroite[1])
if erreurok=0
erreurmsg$="creation: etait :"+str(test)+" et maintenant: "+str(getspriteexists(cadreperso[0]))+" collisiongauche[1]="+str(collisiongauche[1])+" cadreperso[1]="+str(cadreperso[0])
erreurok=1
endif

sometimes cadreperso[1] and collisiongauche[1] have different ID , and sometime the same.
Then erreurmsg$ containt : "creation: etait :0 et maintenant: 1 collisiongauche[1]=100008 cadreperso[1]=100008 (can see it display down screen on picture)

So, deleteallsprite reset all ids after 100000, if i understand its because sprite ID cant be less than 100000 value.So after that appgamekit regive value to sprite ID but must dont give same Value for 2 different ID.And here, sometime, i have these 2 sprite ID with same value.But not all time.And when its same value, i have some others weird bug.Some textid seem have same value to. (i have a text sometime appair in game for say message, and when bug, it give the rest life, like if he as same value as the original text giving the rest life).I have some bad guy sprite in the game who have collision box sprite.One left, right,up, down ... And sometime one of them disappear, i think because an other sprite as same ID value....Im still searching
Sorry for my language, i speak english like a spanish cow.
Thank again for your help!

(thank Qugurun, you make me discover "select" "case" same use as "switch" for php

)

Qugurun, i have use your code and check with replace deletesprite ... with deleteallsprite .and yes deleteallsprite reset ID value, deletesprite dont reset.i think deleteallsprite make this conflict.I have program a longer game before, without use deleteallsprite,deleting sprites in a loop (for a to ... if getspriteexists (mysprite[a]) then deletesprite(mysprite[a]) and no problem .I think my next step is change deleteallsprite by a loop and try.
Thank again!

I have do an other try, and i see this conflict ID come when i clone a sprite from a cloned sprite randomly.If someone can try this code, and can help me for why reason they have same ID?

+ Code Snippet

SetClearColor(40,150,250)
//--------------------------------------------------------------
LoadImage(1, "img.png")
global spr4
spr1=CreateSprite(1)
 spr3=clonesprite(spr1)
LoadImage(2, "img.png")
spr2=CreateSprite(2) : SetSpriteX(spr2, 100)
 
click_step=0
do
    print("id1: " +str(spr1))
    print("id2: " +str(spr2))
      print("id3: " +str(spr3))
        print("id4: " +str(spr4))
    if GetPointerPressed()=1
        select click_step
            case 0:
         	
deleteallsprites()

                inc click_step
            endcase
            case 1:
                spr1=CreateSprite(1)
                spr2=CreateSprite(2) : SetSpriteX(spr2, 100)
                if random (1,10)=1 then spr3=clonesprite(spr1)
                spr4=clonesprite(spr1)
                click_step = 0
            endcase
        endselect
    endif
 
    Sync()
loop

---> if i change deleteallsprites for deletesprite , never clonflict because never reset ID value. I think my solution is not use "deleteallsprites" more, deleteallsprite reset value ID anyway if the id sprite is already deleted, and i think its same problem with deletealltexts for text

This post has been marked by the post author as the answer.

Im totaly missing... With this try i can see after deleteallsprite , a deleted sprite, not created exist. (It create 1 chance on 2 with random, with deleteallsprite it alway created) , with deletesprite it work normally ...

SetClearColor(40,150,250)
setprintcolor(255,10,10,255)
//--------------------------------------------------------------
LoadImage(1, "img.png")
global spr4
spr1=CreateSprite(1)
 spr3=clonesprite(spr1)
LoadImage(2, "img.png")
spr2=CreateSprite(2) : SetSpriteX(spr2, 100)
 
click_step=0
do
    print("id1: " +str(spr1)+" existe: "+str(getspriteexists(spr1)))
    print("id2: " +str(spr2)+" exist: "+str(getspriteexists(spr2)))
      print("id3: " +str(spr3)+" exist: "+str(getspriteexists(spr3)))
        print("id4: " +str(spr4)+" exist: "+str(getspriteexists(spr4)))
    if GetPointerPressed()=1
        select click_step
            case 0:
 	
//deletesprite (spr1):deletesprite (spr2):deletesprite (spr3):deletesprite (spr4):
 deleteallsprites()     
                inc click_step
            endcase
            case 1:
                spr1=CreateSprite(1)
                spr2=CreateSprite(2) : SetSpriteX(spr2, 100)
                if random (1,5)=2 then spr3=clonesprite(spr1)
                spr4=clonesprite(spr1)
                click_step = 0
            endcase
        endselect
    endif
 
    Sync()
loop

            endcase
        endselect
    endif
 
    Sync()
loop

---->id dont exist, but it still have the same id value, so the system say it exist, but it not, because i think deleteallsprite reset value only when it created again, mysprite=createsprite(1) (maybe mysprite=100001), deleteallsprite (), (i think mysprite is still =100001) , mysprite=createsprite(1) (and now i think mysprite get a new value), then , when i try to know if a sprite exists, if he as be deletebefore by "deleteallsprite" , it can be an other sprite id with same value exist, deleted, but this sprite dont have same name id. I think i get it now ! (maybe its a problem when we use deleteallsprite the ID values are not already reset, but the counter)

Final solution
---->
going to still use deleteallsprite but mixed with call this function :

+ Code Snippet

function resetarray (arr ref as integer[] )
memo=arr.length
arr.length=-1
arr.length=memo
endfunction


function deleteallsprites2()
	deleteallsprites()
resetarray (cadreperso):resetarray (matombe):resetarray (cadreperso):fond=0:fonds=0:fondo=0:avatar=0:backt=0:centre=0:backt2=0:resetarray (player):resetarray (collisionbas):resetarray (collisionhaut):resetarray (collisiongauche)
resetarray (collisiondroite):resetarray (collisionsousbas):resetarray (testvide):
resetarray (testpf):resetarray (testpl):resetarray (option):
resetarray (displaygain):
cadrechat=0:resetarray (boxchat):barre=0:noir=0:optionlangue=0

endfunction

function deletealltext2()
deletealltext()
resetarray (score):resetarray (textclone):resetarray (nom):resetarray (contenu):
resetarray (players):resetarray (etat):maxpt=0:resetarray (nomperso):
resetarray (textchat):infos=0:gameover=0
retoursalon=0:relancer=0:titretemp=0:titre=0:flvl=0
chatencour=0:load=0:erreurmsg=0:monscore=0

endfunction

for all arrays need to be reset

seem workin

thank again to all
