Hi you can use a negative force on the particle emitter but id create an object attach tween behaviour and do something like…
spawn particles is true
if number of particle objects less than 30
then …set ‘randang’ to randoninrange(1,360), set randtime to (randomfloatinrange .2,2) and create particle at spawn pointX() +xfromangleanddistance(randang,radius), spawn pointY() +yfromangleanddistance(randang,radius) and
tween particle position to spawn point in randtime secs and delete yes
and also tween the opacity to zero
I find it a little ridiculous having to do all that complex crap just to have the particles go inwards. I’d much rather find a diffrent way to introduce the boss than jump through al those hoops.
You’ve got quite a small force. They dont go towards the center with a negative force …but it looks ok
but Its quite quick to set up something like this…
