Why doesn't my setFocus work?

Hey guys,

I can’t work this one out and man have I tried. If the argument is true then I want the attackButton to be the only thing the user can select. They have to hold it down otherwise the attack finishes. It semi-works but only if the user keeps their finger directly over the button when they release or presses the button then lets their finger roam bringing it back to rest directly over attack button then release. Also my joystick is still selectable the whole time. Not good, I want the joystick disabled.

Any help would be greatly appreciated

Here I create the attackButton

[lua]—Create Attack Button

attackButton = ui.newButton{
defaultSrc = “AttackButton.png”,
defaultX = 51,
defaultY = 51,
overSrc = “Attack-Button-Pressed.png”,
overX = 51,
overY = 51,
onEvent = attackButtonHandler,
id = “attackButton”,
text = “”,
font = “Helvetica”,
textColor = { 255, 255, 255, 255 },
size = “”,
emboss = false
}

attackButton.x = 420; attackButton.y = 250;

hudGroup:insert(attackButton)[/lua]
Here is it onEvent Function

[lua]function attackButtonHandler(event)

if event.phase == “press” and smallShip1HitPossible == true and attackPossible == true then

local attackButton = event.target

player.isVisible = false
player.isActive = false
smallShip1.isVisible = false
display.getCurrentStage():setFocus( attackButton, event.id )

local reducesmallShip1Health = function()

if smallShip1HitPossible == true and smallShip1Health >= 1 then
smallShip1Health = smallShip1Health -10

elseif smallShip1HitPossible == true and smallShip1Health <= 1 then

timer.cancel(smallShip1CollisionTimer)
player.isVisible = true
attacksheet:dispose()
smallShip1:removeSelf()
timer.cancel(playerCollisionTimer)
attackPossible = false
smallShip1HitPossible = false

end

end

smallShip1CollisionTimer = timer.performWithDelay(500, reducesmallShip1Health,0)

attacksheet = sprite.newSpriteSheet(“attack.png”, 55, 169)

attackset = sprite.newSpriteSet (attacksheet, 1, 2)
sprite.add (attackset, “grab”, 1, 2, 300, 0)
sprite.add (attackset, “attack”, 2, 2, 300, 0)

newAttack = sprite.newSprite (attackset)
newAttack.x = smallShip1.x
newAttack.y = smallShip1.y
newAttack:prepare(“grab”)
newAttack:play(“attack”)

camera:insert(newAttack)

elseif event.phase == “release” and attackPossible == true then

display.getCurrentStage():setFocus(attackButton, nil)

smallShip1HitPossible=false
if smallShip1HitPossible==false then
if(smallShip1CollisionTimer~=nil) then – just to be safe
timer.cancel(smallShip1CollisionTimer)
end
end

player.isVisible = true
smallShip1.isVisible = true

attacksheet:dispose()

setFocus() requires just one parameter, why do you pass it two?

the way to setFocus is setFocus(control)
and to remove the focus is setFocus(nil)

cheers,

Hey jayantv. I’ve tried multiple ways. Do you mean like this? Because I’ve tried lots of different ways.

Cheers for the response

player.isVisible = true
attacksheet2:dispose()
smallShip2:removeSelf()
timer.cancel(playerCollisionTimer)

end

end
