+ Code Snippet

    PrintC ( \\\"GetVirtualButtonState = \\\" )
    Print ( GetVirtualButtonState (2) )

    if ( GetVirtualButtonState( 2 ) = 1 )
        PlaySprite( 1,15 )  //shoot
        Print ( \\\"Button Held\\\" )
    endif

Upon loading, the code prints GetVirtualButtonState = 0
When holding down the Virtual Button the state changes to 1 and prints \\\"Button Held\\\" but the animation does not play.
Releasing the Virtual Button the code prints GetVirtualButtonState = 0 The \\\"Button Held\\\" goes away and then the animation plays.

I assumed that if GetVirtualButtonState = 1 it should display \\\"Button Held\\\" and play the animation or am I missing something.
I didn\\\'t find anything in the doc\\\'s or the forum about this.
Any Thoughts?

Shall we play a game?” - Joshua

You are already calling getVirtualButtonState so it will reset the value maybe?

Try this:

+ Code Snippet

vb2 = GetVirtualButtonState (2)
PrintC ( "GetVirtualButtonState = " )
Print ( vb2 )

if ( vb2 = 1 )
    PlaySprite( 1,15 )  //shoot
    Print ( "Button Held" )
endif

I think the issue is that when you hold the button down, you are constantly calling 'PlaySprite'. This will not work as when you call 'PlaySprite' it plays it from the beginning. Constantly calling it, would make it appear to not be working (when in fact its just starting again every loop)...

Try this...

+ Code Snippet

    PrintC ( \\\"GetVirtualButtonState = \\\" )
    Print ( GetVirtualButtonState (2) )

    if ( GetVirtualButtonState( 2 ) = 1 )
        if GetSpritePlaying(1) = 0
            PlaySprite( 1,15 )  //shoot
        endif
        Print ( \\\"Button Held\\\" )
    endif

And then you would probably want to create another if statment for when the button is released, to stop the sprite from playing...

Good thought there @Funnell7, you could be right but the sprite should continue playing after he has released the button... I guess it depends how many animation frames there are as to how visible the result would be?

EDIT: Also he's not using loop so it should just stop after the animation I think on the last frame?

I tend to set animation frames manually, it's far more easy to keep full control (for me anyway)

The OP said that when they release the button, the animation plays

EDIT: regarding the looping... I believe the default is for it to loop...

So it does, I misread that

Quote: "regarding the looping... I believe the default is for it to loop..."

Correct again!

Quote: "iLoop - the looping mode of the sprite, 0 equals do not loop, 1 equals loop forever (optional, default 1)."

I thought he was saying it wasn't playing at all, my mistake.

Makes perfect sense that the animation would be starting from the beginning each loop appearing not to work. It works and lesson learned Funnell7, in fact an example does show it and I over looked it.
