    Originally the missiles did use the Bullet behavior however the bug was still present. I changed the code to use Move Forward to ensure it wasn't related to the Bullet Behavior.

    I didn't come across any problems with the fps, during the game there are only a maximum of 20-25 enemies and 40-50 missiles at peak times also each missile has a short 5 second life span, so nothing close to the test files I uploaded.

    I've only been using Construct 2 for 4 weeks so still not 100% sure what to expect in regards to Construct 2 speed capabilities and which routines are quickest. Now that I am a little closer to understanding what is causing the errors I'll probably revert back to using the Bullet Behavior.

    That is an interesting result as I felt there had to be a double call somewhere. As I mentioned above the bug was present when I had the missiles controlled by the Bullet Behavior which is still odd.

    I guess there could have been a problem during the For Each missile loop as well, however I doubt I would have spotted it as it was only used to control the turning and lifetime.

    Cheers all

    I hoping that in the short term if I use a single event sheet for the game that will cure the problem.

    Glad that you can confirm the behavior.

    This being my first project in Construct 2 and still learning the setup and calling functions etc, I went through rewrote, shuffled events so many times to ensure it wasn't my code.

    Naturally I only used one event sheet when I started bug testing, so I did feel I was starting to lose the plot when I couldn't reproduce the bug.

    While I was reducing the code down the bug went away when everything was on one event sheet. I thought that perhaps the bug was caused by calling the explosion function from another event sheet...

    However it seems simply including an empty event sheet makes the bug appear

    • > If I include the empty event sheet the bug appears
    • > If I remove the include to the event sheet the bug disappears

    This has left me very puzzled

    Browser Effected:

    Firefox: yes

    Chrome: yes

    Steps to reproduce:

    Fly the ship around for approx 20-30 seconds and you will see that some missiles move faster than others

    Trigger:

    Events Sheet: EvadeMain

    Group: Main - Collisions Section

    When the particle explosion is created via a function some missiles end up moving faster than they should

    When the particle explosion is created directly in the collision code the bug isn't present

    Observed result:

    Odd missiles move at double speed

    Expected result:

    All missiles should move at the same speed

    Browsers affected:

    Chrome: yes

    Firefox: yes

    Operating system & service pack:

    Windows 7 Professional

    Construct 2 version:

    Release 139 (64-bit/Steam)

    Notes:

    Although this test uses lots of spawned enemies and missiles to ensure the bug shows up, it also appeared during level testing when I had only 10 or so enemies and perhaps 20-30 missiles.

    The bug was also present in other tests when the missiles used the Bullet Behavior / Move Forward command / direct Sin,Cos calculations.

    Using some quick calculations on other tests I found the bugged missiles moved at exactly double the speed they are set to.

    Please forgive the slightly larger code, I have spent five days tracking down this bug, from dissecting my game to creating small tests. In the end I started building my game from ground up slowing adding pieces until finally the bug appeared again.

    I will try and create a more compact test later next week

    Cheers
