OK let’s say you have a game like when you throw a ball at pins. You are allowed to have three balls and you have three pins. If you hit the last pin with the last ball you need your game to be won. But you used your last ball so at the same time the game is saying that you lost. Does anyone have any ideas about how you could throw the last ball and not have game over until you know the ball didn’t hit the last pin? [import]uid: 49863 topic_id: 30306 reply_id: 330306[/import]
This is only an ide, but dont dispatch an event when the ball gets thrown, instead check how many balls are left and how many pins are left, maybe with a timer. If ball == 0 and pins > 0 then dispatch the lose event otherwise the won event. Since you havent posted any code its hard to help to pinpoint exactly what you can change. [import]uid: 126729 topic_id: 30306 reply_id: 121406[/import]
I would have post a lot of code for this. I tried the if ball == 0 and pins > 0 the game ends while ball is still being thrown. So in the time it takes the last ball to hit the last pin the lose event starts and once the last pin is hit the next level loads. [import]uid: 49863 topic_id: 30306 reply_id: 121410[/import]
Thats why you should delay the event. You know when the last ball is being thrown, then start a timer for a second or how long it now takes, and then call a function who checkes ball vs pins.
[import]uid: 126729 topic_id: 30306 reply_id: 121412[/import]
Not a bad idea I will try it out. Thanks for the suggestion. [import]uid: 49863 topic_id: 30306 reply_id: 121413[/import]
Well I wasn’t able to figure out a way to make this work. Here is the code maybe it will trigger a light bulb for someone who already knows how to do this. I just picked out the parts I thought were necessary. If something seems to be missing let me know and I will include that as well. Thanks
[lua]-------------in the update function-------
if dartsLeft == 2 then
dart4.isVisible = false
gameState = “removing balloons”
elseif dartsLeft == 1 then
dart3.isVisible = false
gameState = “removing balloons”
elseif dartsLeft == 0 then
dart2.isVisible = false
gameState = “removing balloons”
end
if balloons.numChildren == 0 and gameState == “removing balloons” then
if dart4.isVisible == true then
dart4.isVisible = false
end
if dart3.isVisible == true then
dart3.isVisible = false
end
if dart2.isVisible == true then
dart2.isVisible = false
end
dartsLeft = 0
end
if dartsLeft == 0 and balloons.numChildren ~= 0 then
gameState = “over”
end
-------------------------------the following happens when the player beats a level
– we start building the next level
function changeLevel(event)
if balloons.numChildren == 0 and gameState == “removing balloons” and table.maxn(levels) ~= currentLevel and gameState ~= “lost” then
timer.performWithDelay(2500, createLevel, 1)
Runtime:removeEventListener( “enterFrame”, changeLevel)
gameExitBtn:removeEventListener(“touch”, removeListeners)
end
end
------------------------------------function for losing
function lost(event)
if balloons.numChildren ~= nil then
if gameState == “over” then
if dartsLeft == 0 and balloons.numChildren > 0 then
Runtime:removeEventListener(“enterFrame”, lost)
gameLosing()
end
end
end
end
local gameLosing = function (event)
gameState = “lost2”
btPopUpt()
end
[import]uid: 49863 topic_id: 30306 reply_id: 121533[/import]
I guess you are trying to make the update in the enterFrame listener. If i would try to do this i would do it through a touch listener. I guess you have a touch listener already for making the throws.
Then try something like this:
[lua]local function checkGameState()
if (dartsLeft == 0 and ballonsLeft == 0 ) then
–Call Win
else
–Call Lose
end
end
local function throwDart()
dartsLeft = dartsLeft -1
–Rest of the darts visible checks
if (dartsLeft == 0) then
timer.PerformWithDelay(1000, checkGameState)
end
end
background:addEventListener(“touch”, throwDart) – add the listener to the object you are throwing/touching[/lua]
[import]uid: 126729 topic_id: 30306 reply_id: 121537[/import]
OK that won’t work either because once the dart is fired then balloons.numChildren is not equal to zero yet but the darts are. This fires the lost game event but then that last dart can hit that last balloon allowing for the game win event to happen. I didn’t want to have to do this again but here is all of the code for the mini game.

Ok there are some different ways for you to achieve what you are trying to do. The first one came to mind is doning this. Try to replace the code from line 559 - 563 with this. Im pretty sure this works. And change your if in the won(event) to if gameState == “won” then
[lua]local lastDartThrown = false
local function checkGameState()
if dartsLeft == 0 and balloons.numChildren ~= 0 then
gameState = “over”
else
gameState = “won” --Your win gamestate.
end
end
if dartsLeft == 0 and balloons.numChildren ~= 0 then
if (lastDartThrown == false) then – This to stop multiple timers from starting
lastDartThrown = true
timer.performWithDelay(2500, checkGameState) – After 2,5 sec or the timeframe from dart is thrown until the balloon should have been hit.
end
end[/lua]
Another way, a bit more to change but probably better, is to remove the runtime enterframe listeners for won and lose and instead count down number of darts inside the onCollision(event) function. and if dartsLeft == 0 then checkGameState() end. And then use the above checkGameState function i wrote, but instead of setting the gamestate there you call the won() or lose() functions depending. This because you already dispose the balloons in there, why not count down the darts there aswell. Then when dartsLeft == 0 you start the timer and call checkGameState. [import]uid: 126729 topic_id: 30306 reply_id: 121745[/import]
This is only an ide, but dont dispatch an event when the ball gets thrown, instead check how many balls are left and how many pins are left, maybe with a timer. If ball == 0 and pins > 0 then dispatch the lose event otherwise the won event. Since you havent posted any code its hard to help to pinpoint exactly what you can change. [import]uid: 126729 topic_id: 30306 reply_id: 121406[/import]
I would have post a lot of code for this. I tried the if ball == 0 and pins > 0 the game ends while ball is still being thrown. So in the time it takes the last ball to hit the last pin the lose event starts and once the last pin is hit the next level loads. [import]uid: 49863 topic_id: 30306 reply_id: 121410[/import]
Thats why you should delay the event. You know when the last ball is being thrown, then start a timer for a second or how long it now takes, and then call a function who checkes ball vs pins.

I guess you are trying to make the update in the enterFrame listener. If i would try to do this i would do it through a touch listener. I guess you have a touch listener already for making the throws.
Then try something like this:
[lua]local function checkGameState()
if (dartsLeft == 0 and ballonsLeft == 0 ) then
–Call Win
else
–Call Lose
end
end
local function throwDart()
dartsLeft = dartsLeft -1
–Rest of the darts visible checks
if (dartsLeft == 0) then
timer.PerformWithDelay(1000, checkGameState)
end
end
background:addEventListener(“touch”, throwDart) – add the listener to the object you are throwing/touching[/lua]
[import]uid: 126729 topic_id: 30306 reply_id: 121537[/import]
OK that won’t work either because once the dart is fired then balloons.numChildren is not equal to zero yet but the darts are. This fires the lost game event but then that last dart can hit that last balloon allowing for the game win event to happen. I didn’t want to have to do this again but here is all of the code for the mini game.

Ok there are some different ways for you to achieve what you are trying to do. The first one came to mind is doning this. Try to replace the code from line 559 - 563 with this. Im pretty sure this works. And change your if in the won(event) to if gameState == “won” then
[lua]local lastDartThrown = false
local function checkGameState()
if dartsLeft == 0 and balloons.numChildren ~= 0 then
gameState = “over”
else
gameState = “won” --Your win gamestate.
end
end
if dartsLeft == 0 and balloons.numChildren ~= 0 then
if (lastDartThrown == false) then – This to stop multiple timers from starting
lastDartThrown = true
timer.performWithDelay(2500, checkGameState) – After 2,5 sec or the timeframe from dart is thrown until the balloon should have been hit.
end
end[/lua]
Another way, a bit more to change but probably better, is to remove the runtime enterframe listeners for won and lose and instead count down number of darts inside the onCollision(event) function. and if dartsLeft == 0 then checkGameState() end. And then use the above checkGameState function i wrote, but instead of setting the gamestate there you call the won() or lose() functions depending. This because you already dispose the balloons in there, why not count down the darts there aswell. Then when dartsLeft == 0 you start the timer and call checkGameState.

Sorry I am having internet issues right now so I am typing from my phone. I tried your method and it works till the game reaches level three then it wont detect losing at all.
[import]uid: 49863 topic_id: 30306 reply_id: 123572[/import]
Is it my solution that dosent work on level 3 or is it the game in general? You have alot of Runtime EventListeners, are you sure that you dispose of them when you clear a played level? Maybe thats the problem. [import]uid: 126729 topic_id: 30306 reply_id: 123701[/import]
