Game Dev Assistance Needed

primoz.cerar · January 30, 2014, 8:44am

As marcior suggested if you have only one hare visible at a time you can check it before you show the next hare in you showHare function:

function showHare(e) if lastHare.isVisible then lifeIcons[lives].isVisible = false lives = lives - 1 if( lives == 0) then alert() end end lastHare.isVisible = false local randomHole = math.random(1, 11) lastHare = hares[randomHole] lastHare:setReferencePoint(display.BottomCenterReferencePoint) lastHare.yScale = 0.1 lastHare.isVisible = true Runtime:addEventListener('enterFrame', popOut) end

@primoz.cerar, yeah thanks your suggestions helped!

Do you think it is possible to have “waves” or “rounds” in my game. For example, wave 1 starts off with 20 hares to advance and so on, thanks guys, much help!

primoz.cerar · January 31, 2014, 7:28am

Well yes all you need to do is to handle how and when you call the timer for the next hare. I can’t really give you code snippet as it is very dependent on your code and how you want the waves to be. Play with it a little I’m sure you will get it. Clue: When you want a break between waves just put a longer delay in the performWithDelay function.

Here is my showHare() and start timer function, would you suggest a timer in the “showHares function” that when reached a “totalHares” it finishes a wave?

local function showHare() &nbsp; &nbsp; if lastHare.isVisible then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;lifeIcons[lives].isVisible = false &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;lives = lives - 1 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if( lives == 0) then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;alert() &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;end &nbsp;&nbsp;&nbsp;&nbsp;end &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;lastHare.isVisible = false &nbsp; &nbsp; local randomHole = math.floor(math.random() \* 11) + 1 &nbsp;&nbsp; &nbsp; &nbsp; lastHare = hares[randomHole] &nbsp; &nbsp; lastHare:setReferencePoint(display.BottomCenterReferencePoint) &nbsp; &nbsp; lastHare.yScale = 0.1 &nbsp; &nbsp; lastHare.isVisible = true &nbsp; &nbsp; transition.to(lastHare, { time=300, yScale=1 }) end function startTimer()&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;timerSource = timer.performWithDelay(timeToNextHare, startTimer) &nbsp;&nbsp;&nbsp;&nbsp;showHare() &nbsp;&nbsp;&nbsp;&nbsp;timeToNextHare = math.max(timeToNextHare - 30, 600)&nbsp; end &nbsp;

primoz.cerar · February 1, 2014, 9:26pm

a timer in showHare won’t stop the timer you started in startTimerFunction.

You should be checking in starTimer whether you need to make a pause.

local wave = 1 local waveTable = {10, 15, 12, 14} local waveHares = 0 function startTimer() if waveHares == waveTable[wave] then wave = wave + 1 waveHares = 0 timerSource = timer.performWithDelay(timeToNextWave, startTimer) return end timerSource = timer.performWithDelay(timeToNextHare, startTimer) showHare() timeToNextHare = math.max(timeToNextHare - 30, 600) end

julianchiu · February 2, 2014, 4:52am

Okay cool, makes sense, your a big help.

julianchiu · February 2, 2014, 5:08am

To fully comprehend “local waveTable” represents the first wave ending at 10, the second at 15, etc?

primoz.cerar · February 2, 2014, 10:40am

Correct

julianchiu · February 5, 2014, 1:36am

@primoz.cerar, I want to display the number of wave the player is currently on, I did this by adding " wave.text = wave" under “waveHares = 0” in my function startTimer(). The text appears how ever it seems like the waveTable is not updating with the text because it just stays at “0”. Am i missing something here ?

function startTimer() if waveHares == waveTable[wave] then wave = wave + 1 waveHares = 0 wave.text = wave timerSource = timer.performWithDelay(timeToNextWave, startTimer) return end timerSource = timer.performWithDelay(timeToNextHare, startTimer) showHare() timeToNextHare = math.max(timeToNextHare - 30, 600) end &nbsp;

primoz.cerar · February 5, 2014, 4:40pm

Well this should be giving you an error as wave is a number and you’re trying to set the text property of number.

You need to set the text of newText object you created for displaying the wave number which I don’t know how you named as it’s not declared in the code you posted.

julianchiu · February 5, 2014, 9:25pm

My mistake , I forgot to mention I did exactly that in my gameview function(), which my “score” works perfectly fine in when a harehit but does not work for my wave, why is this? Thanks!

function showGameView:tap(e) &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;transition.to(titleView, {time = 300, x = -titleView.height, onComplete = function() startButtonListeners('rmv') display.remove(titleView) titleView = nil end}) &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;score = display.newText('0' , 397, 9, native.systemFontBold, 25) &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;score:setTextColor(255, 200, 0) &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;wave = display.newText('0' , 300, 5, native.systemFontBold, 25) &nbsp;&nbsp;&nbsp;&nbsp;wave:setTextColor(255, 200, 0) &nbsp;&nbsp;&nbsp;&nbsp;prepareHares() end&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;

function hareHit:tap(e) &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;audio.play(hit) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;lastHare.isVisible = false &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if t.type == "hare" then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;haresHit = haresHit + 1 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;local t = e.target &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;hareHit = display.newText('+1000', 380, 45, native.systemFontBold, 18) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;hareHit:setTextColor(255, 0, 0) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;transition.to( hareHit, { time=800, alpha=.01 } ) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;score.text = haresHit&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;elseif t.type == "badhare" then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;lifeIcons[lives].isVisible = false &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;lives = lives - 1&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if( lives == 0) then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;alert() &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;end&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;end end &nbsp;

primoz.cerar · February 5, 2014, 11:23pm

Well you can not have two things with the same name it works in hareHit because youre setting the text of the score variable and you have not named anything else score. But if you check your code you will see before the startTimer function I gave a declatazion local wave = 1 (or 0 don’t remeber which) which is the current wave number then you’re setting a text to a variable with the same name.

Make you wave text named waveText for example and set waveText.text = tostring(wave).

julianchiu · February 6, 2014, 12:55am

Yes, the local wave = 1, however the number of wave displayed on the screen stays at 0, so its between two things my waveTable or my waveText.text = tostring(wave) right?

function startTimer()&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; if waveHares == waveTable[wave] then &nbsp; &nbsp; &nbsp; &nbsp; wave = wave + 1 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;waveHares = 0 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;waveText.text = waveTable &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;timerSource = timer.performWithDelay(timeToNextWave, startTimer) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return &nbsp; &nbsp; end &nbsp;&nbsp;&nbsp;&nbsp;timerSource = timer.performWithDelay(timeToNextHare, startTimer) &nbsp;&nbsp;&nbsp;&nbsp;showHare() &nbsp;&nbsp;&nbsp;&nbsp;timeToNextHare = math.max(timeToNextHare - 30, 600)&nbsp;end &nbsp;

function showGameView:tap(e) &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;transition.to(titleView, {time = 300, x = -titleView.height, onComplete = function() startButtonListeners('rmv') display.remove(titleView) titleView = nil end}) &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;score = display.newText('0' , 397, 9, native.systemFontBold, 25) &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;score:setTextColor(255, 200, 0) &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;waveText&nbsp;= display.newText('0' , 300, 5, native.systemFontBold, 25) &nbsp;&nbsp;&nbsp;&nbsp;waveText:setTextColor(255, 200, 0) &nbsp;&nbsp;&nbsp;&nbsp;prepareHares() end&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;

julianchiu · February 6, 2014, 4:11am

local waveText = 1 local waveTable = {5, 10, 15, 20} local waveHares = 0 &nbsp;

primoz.cerar · February 6, 2014, 11:08am

You are not listening

local waveText = 1

waveText = display.newText(‘0’ , 300, 5, native.systemFontBold, 25)

The second one will override the first one because you setting to the same variable.

local wave = 1 – create variable for wave number

local waveText – just a forward declaration so you have it in scope. it will hold the text display object

in showGameView:

waveText = display.newText(tostring(wave), 300, 5, native.systemFontBold, 25) – create the text display object

then when you want to update it:

wave = wave + 1 – increase the wave number

waveText.text = tostring(wave) – set the text of the text display object to the wave number

julianchiu · February 8, 2014, 12:48am

Okay this time I am sure everything is correct but the “1” does not update with the waveTable since it just stays at “1”, would you mind taking a look at the whole code, thank you.

primoz.cerar · February 8, 2014, 10:31am

You are not increasing your waveHares counter. Try this:

function startTimer() if wavehares == waveTable[wave] then wave = wave + 1 waveText.text = tostring(wave) wavehares = 0 timerSource = timer.performWithDelay(timeToNextWave, startTimer) return end timerSource = timer.performWithDelay(timeToNexthare, startTimer) showhare() wavehares = wavehares + 1 timeToNexthare = math.max(timeToNexthare - 30, 600) end

julianchiu · February 8, 2014, 6:59pm

Thanks for your input!

This unfortunately did not work either, I think the problem lies with the “waveText.text = tostring(wave)” or the waveTable which is probably isn’t being read by the code which does not update the wave round. Any other ideas? I’ll keep trying & let you know what i come up with , thanks!

primoz.cerar · February 8, 2014, 8:32pm

where you have:

waveText.text = tostring(wave)

add infront a print for wave an waveText.text

Without the counter increase I told you about in the last post that code wouldn’t even execute.

So put this infront of waveText.text = tostring(wave)

print(tostring(wave))

print(waveText.text)

Then we will see what you get if you get anything.
