Any particle system without collision enabled, collide with camera
Any particle system without collision enabled, when pointed directly at the camera, will have sprites collide with the camera and slide diagonally off-screen like bird rolling off of a windsheild.
No culling setting or collision flags seem to affect it.
Also that the behavior is the same as when an in-editor user camera gets into a stream of particles, BUT, if the user is looking down or sideways at a particle system, he will see the particles pass right through the camera without being deflected.
2) How can we reproduce it using the example you attached
1 Open attached project
2 Open scene "Particle_CollideNSlide_Bug"
3 Just hit play and watch the game cam.
Here's all I do:
Create a new scene. Create a particle system with a box emitter so that the particles travel in a straight line, and have the velocity aimed directly at the camera.
reproduced on 4.2.0, 4.2.1, 4.2.2 and 4.3.0b4
