New to Fuse4-want a Faery Tale Adventure like game

Ok so for a while I have noticed in my game that it crashes after a few minutes of playing the note music. I get a system error that kicks me out of Fuze and back to the Nintendo Switch main screen. It’s a black screen with a message that says “The software was closed because an error occurred “ [OK ]
I trouble shooted my program by commenting out the play music function in the main program loop. This time as no note music was playing and not touching anything, a couple of minutes later I get a Fuze Stack Overflow error.
My Animated knight function was the culprit. Stack overflow, too many functions called, maximum memory for variables exceeded. (Context: A3777000)
Any ideas what to do next?

Sounds like your function has a bug. Check your loops?
-
@tdg8934 Is it possible that you are creating new sprites using createSprite without first freeing the memory using removeSprite? This can lead to memory leaks.
If you go to Settings -> Preferences -> Show FPS + Memory Meter When Running Programs
and change it to Yes this will display the amount of free memory when you program is running which should show if there is a leak
-
If you are using
loadAudio()then there is a memory leak each time you press + to run your code. Technically the leak is when you go back to the editor. This is fixed in the next release. It's not going to be causing things to crash when the program is running but it won't help if you are also running out every time you stop / start. Right now, there is nothing you can do about this bug aside from come out of Fuze once in a while or not load audio!. Apologies for the inconvenience on that one. -
@pianofire this really helped me identify the function loosing memory . Thank you
-
@Martin thank you but I did not find and code that used the load audio routine
-
@pianofire this is the function I made that is loosing memory .
loop
clear()
DrawMap()
centreSpriteCamera(knight.x, knight.y)
UpdateSprites()KnightWalk()
:
//Draw 9 arrows for direction
Arrows(800,1040,red,green,blue,0)
Arrows(750,990,red,green,blue,90)
Arrows(850,990,red,green,blue,-90)
//6 more arrow function calls
:
playMusic()update()
repeat:
Function Arrows(trx,try,col1,col2,col3,rot)
gw=1950/30
gh=1080/30shape1=createTriangle(gw/3+trx, gh/3+try, gw/3+gw/3+trx, gh/3+try, gw/2+trx, gh-gh/3+try)
setVertexColour(shape1,0,col1)
setVertexColour(shape1,1,col2)
setVertexColour(shape1,2,col3)rotateshape(shape1,rot)
drawShape(shape1)
//update()
return voidEven with 1 Arrows function call looses memory slowly and it crashes
In the knightWalk function it also calls the Arrows function to highlight the direction when the knights button are pressed. Currently those Arrows function calls are commented out. However, it would look like this:
Arrows(800,1040,red,white,blue,0)So it appears my function Arrows is too complicated and looses memory

This post might help...

I think you are losing memory because you are not doing deleteShape() on your arrows after you have drawn them.
This is a serious bug in Fuze, since memory allocated for shapes is not returned even after you quit your program (same as with audio files).
-
@n_yohan thanks but adding another update() or sleep(0.0001) or smaller causes the music and character movement to be very slow and not realistic to use. As well also causes the memory loss and eventual crashing- just slower.
-
@tdg8934 I think that @vinicity has spotted the leak. Add a deleteShape(shape1) after drawShape(shape1)
-
Thank you! That did the trick. All is fully functional again - back to normal. I’ve learned so much with the members and staff in this forum. Great work!

If you notice on the last screen capture there is now a colorful “Action” menu box displayed with selectable smaller menu boxes (ie Inventory, Pause, Take, Look...). I’m able to select each menu box (into high-lighted black boxes with red letters) using the control buttons l, lz, r and rz when pressed. However there are 11 menu boxes and not enough control buttons (as I’m using 4 buttons also to control the animated knight walking).
Does anyone have ideas or code to share on how I might cycle through 1 or 2 buttons to have them go through the menus. I was thinking a counter but when the button is released have it count and move to the next menu box. Is that the right way to handle a situation like this?
thanks - Tim.

@tdg8934 It's been a while since I've played the Mega Drive version... how did that work? The Genesis only had three face buttons, yet I remember it having the little boxes, and I recall the control scheme working just fine.
I actually have a copy of the Genesis port sitting around my basement somewhere...
-
@tdg8934 you could have a box (invisible sprite or area) where your inventory is and detect some form of collision while in there just call the collision and put the controls needed in there that will allow you to use one button for multi purpose. There may be a better way but its worked for me.

We're aware of this and have a fix coming your way soon for shape memory not freeing at program end. In your programs however it's always possible to leak memory if you createShape with no deleteShape!

@Willpowered thank you and I am using the DeleteShape command which is working for me to fix the problem.
-
I haven’t been able to find a method that counts the number of times a control button is pushed. So if c.l is pushed once it does thing 1, if c.l is pushed twice it does thing 2, for let’s say 5 pushes .
I’ve searched “control“ and can’t find a routine that does this.
Anyone have ideas?
Thank you

Counting button presses isn’t so straightforward. You might think you can just make a ‘counter’ variable then put ‘if c.l then counter = counter + 1’, but that will just zip up your counter super fast, 1 per frame. I haven’t done it yet, but my question here: https://fuzearena.com/forum/topic/1195/use-of-flags-with-button-presses will probably be relevant. Maybe.
-
I’d recommend counting when the player lifts their finger as a button press. In my programs, you will often see I don’t make an action occur until then, so as to only have registered the action once.
If you look at my small Game States Demo in the TitleScreen() function, there’s a spot where aPressed==false, meaning they let go of “c.a”. You could increment a global variable count in that spot, such as buttonAcount+=1, and then check if it’s the right count, and then do the action and reset.
