Hi h1rnz1lla
I've attached a screenshot of a section where I use the particles.
It's a pretty simple setup ...
I have a behaviour for the dust particle that has a SizeMin, SizeMax and FadeTime variables as well as some code to send it in a random 360 degree direction on creation + kill itself after FadeTime has elapsed.
When the player lands I create this particle a certain number of times and set it's SizeMin, SizeMax and FadeTime time according to how high the fall was (I set these variables from the player movement behaviour).
The Counter variable in my screenshot is just a variable that holds the Y Speed of the player and it gets reset when the player touches the ground.
Hope this helps and thanks again guys

I'm happy you like the game!
