Fast loop particle movement breaks with more than one particle. Please help.

Hi, everyone.

I've created a particle movement using fast loops to get the perfect collision on the backdrop. However, it doesn't work with more than one particle. I couldn't get the X movement in a loop either.

Here's the .mfa. Clicking the mouse creates a particle, so if you click the mouse rapidly, it breaks.

Can one of the pros on this board please fix it up? Is there an example with this already taken care of? There are lots of particle examples but I couldn't find any which consider perfect collisions with the backdrop.

Thanks, everyone.

When you have more than one instance of the same object on the screen, Fusion doesn't know which one to point to. You need to use a ForEach loop to address them individually.

Thanks, that's perfect. Didn't know there was an in-built ForEach in the event editor. You're a pro.

Hey no prob. Also, in your gravity loop, using two different lines for "if b<0" and "if b>0" can be a bit redundant and resource taxing.

"if b>0" set y to y+1 and "if b<0" set y to y-1 can be done through a single line.

Set y to y + b/abs(b)

This way, if it's more than 0, you end up with y+1 and if it's less, it returns y + -1
