+ Code Snippet

if GetPointerReleased() = 1
	if GetSpriteHitTest(playlevel,GetPointerX(),GetPointerY())
		gamestate = 3
	endif
endif

That is my code. Simple right? Now, look at this problem.

I am trying to press that sprite. Gamestate is printed up the top. When I click the sprite, it does not change the gamestate, which makes no sense. Now, if I change the sprites position to 0,0

?? Here it works perfectly fine. Now, on my title screen I had the exact same issue. I got angry and so replaced it with a button. I would do the same for this but the max amount of buttons you can have is 12 and that is not enough. Any solutions? Anyone ever have the same problem? I could not find this anywhere else on the forum. Thanks!

We would need to see more of your code to know what is going wrong. In principle it should work fine. Here is a stripped back example that works:

+ Code Snippet

SetWindowTitle( "spritehittest" )
SetWindowSize( 500, 500, 0 )

// set display properties
SetVirtualResolution( 100, 100 )
SetOrientationAllowed( 1, 1, 1, 1 )
SetSyncRate( 30, 0 ) // 30fps instead of 60 to save battery


playlevel = createsprite(CreateImageColor(255,255,200,255))
SetSpriteSize(playlevel,10,10)
SetSpritePositionByOffset(playlevel,50,70)

do

	if GetSpriteHitTest(playlevel, getpointerx(),getpointery())
		print("Hit!")
	endif

    Sync()

loop

Keep in mind that GetSpriteHitTest uses world coordinates, so if you have changed the view offset, or zoom then you'll need to adjust GetPointerX/Y using ScreenToWorldX and ScreenToWorldY.

Well, I have this SetViewOffset ( 0, y# - 600 ) but its set to 0 in the main menus case.

Can you tell me more about "float ScreenToWorldX( x )" Would I have to do something like

if GetSpriteHitTest ( playlevel , ScreenToWorldX(GetPointerX()) , ScreenToWorldY ( GetPointerY () ))

I have noticed that it works anywhere on the X scale, but on the Y scale it won't work. Any other ideas?

Exactly it!

Not sure what to say. Here's the same stripped-down example using view offset on the y scale and screentoworldx/y:

+ Code Snippet

// set window properties
SetWindowTitle( "spritehittest" )
SetWindowSize( 500, 500, 0 )

// set display properties
SetVirtualResolution( 100, 100 )
SetOrientationAllowed( 1, 1, 1, 1 )
SetSyncRate( 30, 0 ) // 30fps instead of 60 to save battery


playlevel = createsprite(CreateImageColor(255,255,200,255))
SetSpriteSize(playlevel,10,10)
SetSpritePositionByOffset(playlevel,50,-530)

setviewoffset(0,-600)

do

	if GetSpriteHitTest(playlevel, screentoworldx(getpointerx()),ScreenToWorldY(getpointery()))
		print("Hit!")
	endif

    Sync()

loop

move your mouse pointer over the box. Does it detect the hit? Works fine for me.

Yes, it does detect the hit. But it doesn't do anything when it is being pressed.

+ Code Snippet

function levelscreen()

// set visible
SetSpriteVisible(playlevel,1)

//set invisible
SetSpriteVisible(titlescreenheader,0)
SetVirtualButtonActive(3,0)
SetVirtualButtonVisible(3,0)

//next state
if GetSpriteHitTest(playlevel, screentoworldx(getpointerx()),ScreenToWorldY(getpointery()))
	if GetPointerPressed() = 1
		gamestate = 3
	endif
endif

endfunction

// 1 set sprites visible
select gamestate
    case 1
		
        titlescreen()
        
    endcase
    case 2
        
        levelscreen()
        
    endcase
    case 3
        playerfull()
    endcase
endselect

print (gamestate)

I've tried everything I could think of :p

Getpointerpressed will indicate a value only for the initial frame its detected on.

Getpointerreleased will give you a value only on the frame its detected on

I think you may be lookin for getpointerstate? That will hold a value as long as your pointer is pressed on the screen

Also need a sync command called to update those agk commands to function properly.... Some ideas of what may be missing...
