Load particles via code

- So we've looked at creating particle systems…in a couple of different ways.…But, what if we wanted to instantiate…a particle system through code?…So, here I've actually created a spark particle.…So I created the file.…And I tweaked it a little bit.…So, I changed the birth rate,…maximum number to 100.…So, birth rate's 2,000, the maximum is 100.…Now that's important.…If you have it at zero, it will go on forever.…This is going to occur one time.…So, what we're seeing here is actually…the particle system repeating.…

So, it's looping.…So, I've made some other tweaks here,…and you can scroll down and check…them out if you'd like.…But, I haven't really changed much.…The main thing is I've changed…the blend mode to alpha.…And I've also changed the particle texture…to my particle, which is just a white circle that's solid.…Also, if you find that you're not seeing…the particles running on your screen,…you can just close your Xcode project.…And then open it back up and you…should see the particles again.…Another change I've made to this file…
