Hi,
any one have idea about how to detect Long Press.
Thanks. [import]uid: 11428 topic_id: 17222 reply_id: 317222[/import]
Use timer.performWithDely() to check how long press has been going for

Hi Peach ,
In my code i have two option one for simple fire & one is power fire.
If is this power fire (It’s 3 in every level ) then allow long press event (change images of Tank during longtouch event) otherwise not.
So in this case i want know isLongPress before the “ended” phase of “Runtime:addEventListener(“touch”,onTouch)”.

You’d use a timer. You’d start it when the event.phase == “began” and end it on “ended” then see how long it was pressed for and if it was more than 2 seconds (or whatever) make it a long press.
Get it? [import]uid: 52491 topic_id: 17222 reply_id: 65011[/import]
Hi Peach,
Thanks
My problem is 70% solved with timer.
I was used timer.performWithDelay() in event.phase == “began” .
But problem is if fire is fast one after another then some time Powerfire is twice & second thing is in some case if it is not Longpress then also PowerFire is called.
My code is :
[lua]local isLongPress = false
local powerLaserCount = 0
local onTouch = function( event )
eventPhase = event.phase
if event.phase == “began” then
isLongPress = false
local timerlistenerCount
if powerLaserCount < 4 then
local function listenerCount:timer( event )
if event.count == 10 and eventPhase ~= “moved” then
if eventPhase ~= “ended” then
isLongPress = true
powerLaserCount = powerLaserCount + 1
– Set Power tank animation here
local function listenerCount2:timer( event )
– Stop Power tank animation here
local function laser_fire:timer( event )
fire(1)
end
fire_timer = timer.performWithDelay(300,laser_fire,1)
end
timer.performWithDelay(2000, listenerCount2,1)
end
end
end
timerlistenerCount = timer.performWithDelay(50, listenerCount,10)
end
end
elseif event.phase == “moved” then
– Set move code here
elseif event.phase == “ended” then
eventPhase = event.phase
if isLongPress == false then
function laser_fire:timer( event )
fire(0)
end
fire_timer = timer.performWithDelay(300,laser_fire,1)
end
end
end

I have added < lua > tags to your code. Please use them. (It makes it a lot easier to read.)
The firing twice issue just means you aren’t setting the ability back to false quickly enough; can you do it at the same time the (long) laser is fired? [import]uid: 52491 topic_id: 17222 reply_id: 65373[/import]
you can try this,
[lua]local myTimer
local isLong = false
local function detectLong(e)
if “began” == e.phase then
myTimer = timer.performWithDelay(1000,function ()
isLong = true
end)
elseif “ended” == e.phase then
if isLong then
print(“long”)
else
print(“not long”)
end
isLong = false
if myTimer then
timer.cancel(myTimer)
myTimer = nil
end
end
end
