  • hi,

    after a lot of work and search i finally optimize my game and now is playable faster on iphone 3gs and iphone 4

    i recuce memory usage from 54 mb to 12mb

    reduce cpu usage fro 49% to 19%

    and fsp from 49 to 58-60

    what i do :

    -just read and read tutorial about optimize performance and apply them

    -use tiled background

    -desable behavior and enable them only when it is necessaire

    -use of family and groups

    -desable collisions and enable the only when it is neccesaire

    -optimize size of sprite and avoird transparent spaces

    you can give me your feedback

    here is my new game

  • Try Construct 3

    Develop games in your browser. Powerful, performant & highly capable.

    Try Now Construct 3 users don't see these ads

  • new update 1.1

    -add 2 game mode (classic and swing)

    -add new unlockable character

    -optimize performance

    now gameplay is much better

  • hi,

    i would like to announce that my swing copters clone is avalaible on appstore

    after 10 hours of work, "piggy copters" is out and i get more than 100 downloads in one days

    8 characters players (4 avalaible and 4 unlockable)

    3 difficulties (easy,medium and hard)

    6 medals to win

    6 achievements to complete

    great pixalized graphic and amazing sounds effects

    any feedback / bugs report / suggestions are welcome

    thanks for rate my game (its important for small passionate indie game )

    thanks to all members for help me specially ashley, aphrodite, colludium, silverforce

  • i understand that crosswalk and phonegap are the future of exporting in future(next 6 months)

    but for now we need conconjs for our small project specially because cocoonjs support canvas + (faster than canvas of ejecta and better for wracker device than webgl)

  • here is what you have to put in browser new window action

    https://twitter.com/intent/tweet?text=Yeahhh my best score on name of your game "& HighScore &" points play it on iPhone and iPad here&url=https://lin of your game

    do the appropriate changes (your game link and name" and encode all the link i give you

    the url for encoding is http://meyerweb.com/eric/tools/dencoder/

    and highscore is global variable of your highscore if you use webstorage

  • add another condition "touching the pause boutton" to the "any touch start (jump) and (invert it)

  • what you want optimize ? the size or the game play ?

  • really ... nice game

    congrats silverforce

    For the collisions, C2 already checks only the bounding box first, then if the bounding box are indeed colliding(very fast to calculate), it checks the true collisions, this can be slower depending on the complexity of the collision polygon, also C2 arranges everything in different cells (areas) if it is possible to reduce the collision checks, but other than that, I do not know much about how it is done.

    As for not checking every tick, I would say for exemple a large (relatively speaking, testing will tell if it works or not) projectile can checks if it is colliding with the player only one tick out of two for exemple, to achieve that, you can add the system condition "Compare two values: tickcount%2 equal to 0", that may help (it could also cause problems in some cases, but I consider that this kind of projectile will be destroyed right after colliding)

    I do not know much about your game so I cannot help a lot, the debugger feature of C2 may help you see what parts are cpu consumming.

    Also, it may be possible that graphics are what kneel you game down, but not sure about that

    you are master aphrodite ...

    but what you mean exactly by the collisions polygons ? the number of polygone or surface of collisions ?

    and maybe if you have time , i can send you my full game to take look on it

    It is not complexity the problem, it is than not only it is not based on a browser technology (ejecta suffer the same issue), it cannot be edited in any way possible by scirra (ejecta atleast can be modified incase of a big issue, I think crosswalk can also be modified too, and phonegap rely on the device itself to do everything), AFAIK there is no way to compile your application offline, or to an ancien version (crosswalk suffer the same issue I think, unless there is a way to mount a crosswalk app offline?), the memory management C2 does is not compatible with cocoonJS and it does not seem to be in ludei's plan to change that, also I think there are solutions to have advertisement and in app purchase in crosswalk and phonegap, not sure about ejecta though, so this argument is for iOS only, CocoonJS does not support all of C2's basic features, and if they do ANOTHER breaking update, user will complain to scirra once again, it is not about JS performances only, it is also about compatibility, you cannot make a big game on cocoonJS nor use all of C2's feature.

    It should not be advertised as an export option of C2, since scirra has 0 control over it (ludei does not seemto care about the request of scirra, scirra cannot correct things by themselves, they cannot do anything, at least intel is listening, while crosswalk has issues, it is still better to make it work than to rely on cocoonJS, and ejecta can be modified in case of a big issue), and so should be depreciated (still usable, but not listed as the others exporters are shown) because it is not a main target of C2.

    As for the main subject of the thread: The plugin is now maintained by a third party only (the community), so it is a third party plugin, but a note about that in the plugin description would be nice to have(with a link to the github maybe?).

    i agree with all what you say but just one thing about memory management

    i , (other users) prefer that the game lunched slow at start (with cocconjs) and be playable quick and fast than run faster and take some lag between layout and on lyout (ejecta memory management)

    i prefer to load every thing at start and wait for some seconds than load fast and have lags on game ...

    thats why ... iam going to turn into cocoonjs

    i see one game on appstore wich have super explosion bomb effect and i try it on my old 3gs and it run perfectly wihout any lagging ... this game was compiled with cocoonjs

  • Ashley

    dont forget that cocoonjs maybe is complicated but faster and performance accelerated using canvas + and support as well web-gl better than ejecta

  • If you are asking me I used this set up. The "kimspeed" is set to 700 in my game.

    I used a global variable/bolean that toggles every touch on screen. So if left is true if goes left else it goes to the right

    [attachment=0:3i4erxlk][/attachment:3i4erxlk]

    thats is simple move left / right by touch the screen

    but if you see the swing copter particularity that when you change direction, there is a little decceleration effect that make the game difficult and addictif then , in the same game , you have to avoid obstacles and by touching the screen not on any moments , but on special moment that make the player not colloide with the obstacles or you die

    what about performance in older device ?

  • hi,

    i will try to demonstrate as simple example

    layout a (player touch the coin update score and show it) and when go to next layout the score is shown ... ok

    layout A

    player on collisions with coin === coin destroy , add 1 to score (global variable) , set text box score to "" & score ( global variable)

    layout B

    on start of lyout === set text to "" & score ( global variable)

    if you do like that , it will work

  • and if you set webgl to on , it will look better too
