removeSprite() not working

Maxwello

@pianofire hi yeh sorry. I meant it doesn't remove it but it does remove it enough to think it's removed it and not let you use it. Atleast last time I tried nearer end January so I was wondering if the same still applies hoping that might help with finding the error if there is one

pianofire

@Maxwello Do you mean it doesn't remove it from the screen? It certainly should do. Do you have an example?

Hi, so excited for all the answers!

Here's a picture of the code and the error message. I can't seem to put any function inside the parameter of settimer(), also tried with setspriteanimation().

My problem is I'm having a sprite show up for a couple of seconds which I later want to remove automatically.

P.S.
Really enjoying the program, it's amazing what you've done and it's really helping me to motivate myself to keep on learning programming.

@Nichson OK so settimer is expecting a user defined function not a built-in one so you would need to do something like this:

function removeSpriteCallback( sprite )
  removeSprite( sprite )
return void

and then call it like this:

setTimer (4, 1, removeSpriteCallback( explosion ) )

I haven't tested this

Nichson

@pianofire So I tried this and the error message now is "incorrect number of parameters for function." for removeSpriteCallback(), which I wrote exactly as you did, strangely enough.

If I remove explosion from setTimer (4, 1, removeSpriteCallback () ) then it says: "Cannot perform this operation on a removed sprite."

FUNCTION: removeSprite

pianofire

@Nichson OK I don't understand that.

I am also not really sure what you are trying to do here. Is there reason that you are starting a timer to remove the sprite rather than just removing the sprite?

Nichson

Hmm, yeah well It's an exploision and I want it to loop just once. If I just leave it, it loops over and over again. :9

@Nichson it is difficult without seeing the rest of your code but I suspect that you are actually calling this multiple times (you can only remove a sprite once). Maybe consider making it invisible instead using https://fuzearena.com/help/view/setSpriteVisibility ?

Nichson

Fixed it! :)

So I had a phase variable that was following the m (map). This made it impossible to change the phase variable as I was still at the same m.

Changed this and now the explosion works out well.

Great that you could help with the callback function, I had a test in school about callback functions, back then I couldn't grasp it but now It's making more sense.

Stay safe.

@pianofire
Yes that's what I meant sorry.
The code would execute meaning the game would run but the sprite would not be removed (it was the player sprite as it happens) I had another action like print "aaa" and another (which escapes me) either side of the removesprite which would happen so I know it was getting to that code.

But if I decided OK it doesn't remove it so let's after the removesprite say do something else with the sprite then when hitting run it would error saying can't do that with a removed sprite.

So I resorted to moving it off screen instead.

I can and will recreate it tomorrow
