  • for each enemy

    system compare two values: distance(enemy.x,enemy.y,player.x,player.y) => 100

    enemy - move towards player.x,player.y

    for the second part I would have a rotating sprite at the players position and pin the enemy to it (trigger once), when distance is less then 100, but there are probably better solutions..

    Thank you very much. I will try it when I get home and will upload the events when finished in case someone needs them too.

  • I saw a post about a whole ago but in 1 hour I couldn't find again so maybe someone can help me out. I got a top down game with spaceships. I will like the enemies to come towards the player and when they are in a defined range I'll like for them to start making circles around the player.

    Any suggestions?

  • When spawning to avoid spikes use fade in top appear more smoothly and maybe don't spawn them all at the same time.

  • I would be very interested in this as well, but mainly for WP8 and Windows Store.

  • The only workaround I know is to lower the resolution of the sprites. It works great for mobiles.

  • I updated the beta 175, exported the project again and retested. It still froze but it seems much better now as I tapped with 5 fingers for 32 seconds. The tap timer reached 799 and then it froze .

    I got the latest phone updates as I got a dev account.

  • You need to update it manually (see the link at the bottom of the forum).

    If you are using the steam version however, this is another story

    Ah dammit, thanks

  • Try Construct 3

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

    Try Now Construct 3 users don't see these ads

  • I checked the option, restarted Construct 2 a few times and nothing is happening.

  • Use emulators, make a test project with a lot more sprites and try to reach the maximum RAM for the low-end emulated device (which is usually 512MB). Once you reach by whatever means possible the 512 in Construct, export it and emulate it; see how it goes.

    You can then extrapolate the results for the higher end devices.

  • I read a lot of optimization info regarding Construct 2, however i could not find anything related to RAM usage, only CPU and GPU.

    Your best bet on an Android device would be to use an app. Sadly I cannot post URLs

    My suggestion is to compare the Construct 2 memory number with those in a test project while using a few scenarios. You might find that the objects not on the screen might not be loaded into the RAM, thus your wardrobe must display as few sprites per page as possible to make it RAM-efficient.

    Here's a snippet on how to create a log file with RAM usage in Android:

    [quote:oub6smek]How to get a heap dump

    I created the heap dump using the emulator.

    I created a new avd for the 1.5 preview:

    android create avd -n test -t 2
emulator -avd test[/code:oub6smek]

Then you can logon to the emulated phone and make sure that the /data/misc directory is writable :

[code:oub6smek]adb shell
chmod 777 /data/misc
exit
[/code:oub6smek]
Heap dumps are actually created by sending the process a SIGUSR1 (-10) signal.

[code:oub6smek]adb shell ps[/code:oub6smek]

check for the pid of your application

[code:oub6smek]adb shell kill -10 pid[/code:oub6smek]

You can check with

[code:oub6smek]adb shell logcat[/code:oub6smek]
whether it works. You should see something like:

[code:oub6smek]I/dalvikvm(  ): threadid=7: reacting to signal 10 I/dalvikvm(  ): SIGUSR1 forcing GC and HPROF dump I/dalvikvm(  ): hprof: dumping VM heap to "/data/misc/heap-dump-tm- pid.hprof-hptemp". I/dalvikvm(  ): hprof: dumping heap strings to "/data/misc/heap-dump-tm124026 3144-pid.hprof". I/dalvikvm(  ): hprof: heap dump completed, temp file removed D/dalvikvm(  ): GC freed 1292 objects / 92440 bytes in 11 sec D/dalvikvm(  ): GC freed 215 objects / 9400 bytes in 963ms[/code:oub6smek]

now you can copy the heap dump from the (emulated) phone to the Desktop machine:

[code:oub6smek]adb pull /data/misc/heap-dump-tm-pid.hprof address.hprof[/code:oub6smek]
  
Now the file you will get does not conform to the "standard" Sun .hprof format but is written in Dalvik's own format and you need to convert it:

[code:oub6smek]hprof-conv heap-dump-tm-pid.hprof 4mat.hprof[/code:oub6smek]

Now you can use the Eclipse Memory analyzer to analyze the memory usage of your application.


Good luck!

  • Thanks zenox98 , I will do that.

  • Have you tried make one sprite for a type of costume and populating that with images ?

    Also how exactly do you test the RAM memory used? Just by looking at the counter on the status bar in Construct 2 at the bottom?

  • I want to buy the personal pack. However I would like to do so from Steam as I have multiple computers and I suppose I can use it from any.

    The question is, how do I link that purchase to this "Je Fawk" account?

    Thanks

  • It's okey, I found out

    Didn't know exactly how to use the angle expression, wasted like 2 hours (not kidding)

    Now all I need is to find out how I can rotate the player so the ship won't instantly turn the other way.

  • Any ideas? :[
