First off, I compile to Android in Freedom Engine because I've got stuck in the compile process just using AppGameKit once too many times to bother again. This assumes that Freedom Engine uses 1.086 to compile the android app, which I believe it does.

I'm posting here anyway because I have two threads on the FE forum from Nov 28 that are completely unanswered.

I'm doing finishing touches to a game, but since this update it doesn't get past this stage:

+ Code Snippet

 x# = 0
    
    while x# < 20.0


        if getSpriteYbyOffset(menuShapes) > 0 and getSpriteYbyOffset(menuShapes) < 10
            setSpritePhysicsVelocity(menuGo, 70, 0)
            setSpritePhysicsVelocity(menuBye, -70, 0)
        endIf


        x# = getSpriteXbyOffset(menuGo)
        
        setprintcolor(0,0,0)
        print("I'm in the loop and stuck")
        print(x#)
        
        sync()
        
    endWhile

It gets stuck when x# is above 20.0 and it doesn't reach a code line beyond endWhile.

It worked before, and it still works in the windows part of AppGameKit but not in FE or deployed to android by FE. Just noticed it also works with the new player broadcast from AGK. (it crashed in a new place after that instead)

After the while-loop the code goes into a Do-loop with a sync() in it. It's to "animate" the menu using physics to get a slightly different result each time you start the game.

Try to write the condition inside parentheses:

+ Code Snippet

while (x#<20.0)

The parser is not very sophisticated , I had problems with repeat/until for example.

Thank you for you input, but it didn't help.

I think it catches when x# is > 20 because that's when the program stops working. Mind you it's not like a normal crash, it keeps playing the music but everything is just frozen in spot. It's like it doesn't move on from the loop even though the loop is done and it has stopped syncing

Is x# actually incrementing? Looks to me that your first block will not update x# if the double conditional fails, or something like that.

I agree with JimHawkins.

This line is the only place that moves the sprite you check:

+ Code Snippet

if getSpriteYbyOffset(menuShapes) > 0 and getSpriteYbyOffset(menuShapes) < 10

And there isn't anything in the loop that moves the menuShapes sprite.

x# increments as it should. Menushapes drops because it's physical and triggers menugo and menubye's movement. It all stops when x# passes 20.0 instead of leaving the loop and letting the menu finish its course and let the user interact with it.

If I could compile this with 1076 the app would be finished by now. I guess I have to spend another 2-3hrs attempting that

Why can't you compile it in v1076?

Does the same thing happen if you use a repeat-until loop?

I think Jim and AL are correct you need to check the Y values of menuShapes. I took out your conditional check and it exited after x# was greater then 20

here's the code I used in FE

+ Code Snippet

menuGo = createsprite(0)

 x# = 0
    setspritephysicson(menuGo,2)
    setspriteposition(menuGo,0,90)
    setSpritePhysicsVelocity(menuGo, 70, 0)
    while x# < 20.0      

        x# = getSpriteXbyOffset(menuGo)
        
        setprintcolor(255,255,255)
        print("I'm in the loop and stuck")
        print(x#)
        
        sync()
        
    endWhile
do

print("exited x# = ")
print(x#)
sync()
loop

Maybe FE is is doing something strange to the Y values of menuShapes ?

[edit]

I used your original code and put a couple dummy sprites in that met your conditional checks and it seems to work fine.

Change the Y value of menuShapes to anything greater then 10 and it'll never exit the while loop

Code for FE again

+ Code Snippet

menuGo = createsprite(0)
SetspritePhysicsOn(menuGo,2)

menuShapes = createsprite(0)
SetSpritePosition(menuShapes,0,2)

  x# = 0
    
    while x# < 20.0


        if getSpriteYbyOffset(menuShapes) > 0 and getSpriteYbyOffset(menuShapes) < 10
            setSpritePhysicsVelocity(menuGo, 70, 0)
        endIf


        x# = getSpriteXbyOffset(menuGo)
        
        setprintcolor(255,255,255)
        print("I'm in the loop and stuck")
       
        
        sync()
        
    endWhile
    
    do
    print(x#)
    sync()
    loop

AL: I just have never succeeded. I've reinstalled and set up the compile environment three times and the advice I usually get after failing is "do it over again", I don't have the patience or time to keep trying, even if I know I have to make it work. It's a horrible mix of procrastination and fear of failure (waste of time)

Hodgey: I'll give it a shot thanks!

Auger: x# does reach 20 in my loop (I print it to check) because menushapes is physical and falls from above the screen
