Implosion particle system
Hi, how do i make a black hole effect with the new particle system? I want to spawn particles at the outer perimeter and each of those particles move towards the center. How can i achieve this, thanks.
Particles are tricky. I would test making them explode outward, which is very do able, then make all those properties negative while enhancing the ellipsoid so they will start out as an already expanded group. $$anonymous$$aybe use force as a negative as well to bring them inward. Tinker my friend! the best thing you can do with particles.

not 100% sure how to do this but under the shape tab set the shape to sphere, the increase the radius to however much you want, then you can set it too emit from shell and from there just figure out how to make it emit too the centre.
hope this helps
just messed around and you can simple change the speed to something like -5 then under emission there is a small arrow next to the rate number, click it change it to curve, now at the bottom right you will see a straight red line, under the line there are other smaller icons with lines test these out to find waht right for you. you can also change the emission rate jsut too the left of the big line.
also for effect use color over lifetime to change it too a different color as it reaches the end of its life.
Thanks this was exactly what i was looking for.,Thanks, exactly what i was looking for.
Is this for Unity3d v4? I'm on v3 and I don't see a shape tab...

In Unity 2017 still, not all shapes have "Emit From" option. What I have used in the "Shape" tab is a circle. Then in the main tab set negative speed and a short lifetime of a particle. Think that is what you are looking for.
