The problem is with particle system scaling when running on browser, however when running in the Simulator - everything behaves fine. An example of the problem can be seen here: Particle system question
Also I have attached a test project here:
ParticleScaling.zip (173.6 KB)
So to reproduce, simple run the attached project and try it in the simulator - press a few of the buttons and witness that scaling of canvas (including particle effect) behaves as expected… then run the same project in the browser and witness that the particles does not scale as expected!
Hope this can be fixed asap!
FYI: Found the bug in 1.3 but it is also present in 1.5 beta 4.1 and beta 5.1.
